    I have noticed an awful lot of questions (which is common across all tech boards) on PSU recommendations.

    I'd like (if I may) to post a post I had originally posted some time ago on another site which I had taken information from various sources in relation to PSU's & recommendations.

    This is quite an extensive list (but may not include every supply, so if yours isn't there, don't worry!), and I do need to update it, but it should at least give forum members idea's in relation to the best brands and ranges that your hard earned money can buy in relation to PSU's.

    Hopefully the mods don't kill me for posting an extensive list of recommendations! And hopefully it will be of help to members :)

    My original post can be found here:
    http://www.hardwareanalysis.com/content/topic/66076/

    But I shall copy the info here, so as not to attract users to another site for no reason.

    I have given credit & links to other sites which I have used to compile this information, and I would encourage users to visit their sites also.

    Bumped down to tier 4 due to a number of reports of failure in the line of duty

    And before you nimrods start whining about why your beloved OCZ only made tier 4... this is four tiers of HIGH END products. If the product isn't even on the list, it could be that I either don't know about it or it's not considered high end. So if your PSU is actually in teir 4, grab your e-Peen and know that you at least made the worst of the best.

    Of course, there's always more to be added later.....

    And, before you ask, there's not enough data about the 1000W or 1010W FSP built units for me to make a judgement call so don't ask. Unlike some sites, I don't go "oh goody! Silverstone has a new PSU!!! Let's make it tier 1" without actually testing it. Sorry.

    Many thanks to Perkam of Xtremesystems for the list.

    This should give you a quick reference of what to buy, and what not to buy. Some more units than listed above, but most info taken from JonnyGuru.
    WHICH ONES TO BUY ??

    Tier 1 can handle 4Ghz Conroe or 3Ghz AMD along with Oced Quad Crossfire/SLI With Ease.
    Tier Z offers quality and power unequalled in its wattage range and is second only to other Zippy units.
    Tier 2 offers almost as much power and stability as Tier 1 at Comparable Wattage levels with lower price/better availability.
    Tier T offers the high quality components of Tier 2 with slightly less Rail stability due to Topower internals.
    Tier 3 is ONLY Recommended if Price difference is present between Tier 3 and Tier 2 or due to availability issues with Tier 1/2 PSUs.
    Tier 4 is recommended for stock or low power systems if Tier 3's are more expensive or are not available.
    Tier 5 are NOT RECOMMENDED, but some brands have high/medium quality components in Tiers 2 through 4.

    Only two things wrong I can see.

    One is the omition of the Corsair TX series. Yeah, they are nor modular, but damn good power supplies, if not as good as the HX because of their multi rail format. Should be under Teir T at least.

    Also it is perfectly acceptable to say Seasonic make good PSUs. Even jonnyguru says so :P
    In looking at the low load test results, I'm starting to wonder if I shouldn't have put a big red warning logo above it to warn you to sit down first. I heard crashing noises - I hope you guys are ok. Personally, I was already sitting down when I did the math for this table, else I'd be in the hospital right now. There just isn't room for a six and a half foot tall guy to fall safely in this room and not take serious injury.
    Avert your eyes! The above shots are too awesome for human eyesight to tolerate! Yes, folks, this here Seasonic platform has decided to out-awesome just about everything I've tested to date.


  • Registered Users Posts: 7,692 ✭✭✭Dublin_Gunner


    Hi Leman_Russ - I believe the statement was made in order to not let people assume that any PSU manufacturer is always 'good' or always 'bad'.

    Yes, Seasonic units are generally extremely well performing units. And I have in fact, never heard of anybody complain of one, or have to return one.

    Seasonic was probably a bad example to use! (I shall edit lol)

    IN relation to the Corsair TX units, they are not modular - I wouldn't hold that against them though! But the list does not intend to include every range of PSU for sale, as I'd be here all day updating it! But I do indeed intend to update the list, to try keep it as contemporary as is possible.

    I'll see if I can get some more info on the TX units, and update the list accordingly.

    Nearly all posters on this forum looking for advice firstly, don't have a clue about anything to do with what kind of wattage their pc might need.

    Generalising what certain psu's can be used for such as "suitable for xfire/sli" is dangerous and really IMO the best advice for anyone in the market for a new psu is "op specific"(if you know what i mean).

    Is this just supposed to be a big page for referencing?

    Is this just supposed to be a big page for referencing?

    For a start, the posts references the PSU certification, if you actually look under each model you would see that.

    If someone comes looking for a PSU, at the very least the list provides recommended models and manufacturers.

    PSU can indeed be generalised, contrary to your post. They all do the exact same thing - provide power to your PC. However, if you're looking to power 2xHD5890's in Crossfire, I think you'd already know that a 500W unit is not going to suffice.

    It would be impossible to provide a list and post exactly what spec system each PSU would be suitable for - so please get off your high horse and stop being so pedantic.


    There is nothing dangerous about this thread lol

    For instance, if someone posts looking for advice on a PSU, they could be informed that a 650W PSU will suffice, and they could then reference this thread for a few recommended models in that range, and pick one that they can purchase locally / online etc

    Obviously, not all of these PSU's are going to be available everywhere.

    I think in general the opposite is the main problem though. ie. 'I have ordered a HD4670 and an AMD 550 BE X2, Is this Antec 1200W psu enough?' :)

    lol yeah.

    Power requirements are so inflated these days its not even funny.

    i7 overclocked + 4gb ram + 2 HDD's + HD5870 overclocked etc would probably not break 450W loaded. However, a little extra is always good.

    Personally, I'd never really recommend anything below 550W these days - there's no real point. You can get really good units around that wattage for good prices these days.

    In fact - this should apply even more-so to mods.

    However, if you're looking to power 2xHD5970's in Crossfire, I think you'd already know that a 500W unit is not going to suffice.
    Most people on this wouldn't have the foggiest
    It would be impossible to provide a list and post exactly what spec system each PSU would be suitable for -
    Of course it would be
    so please get off your high horse and stop being so pedantic.

    I am firmly placed on the ground and the fact is that maybe on more "Tech orientated" forums it is common knowledge that two 5970's in xfire would require a better psu than 500watts, but here that cannot be taken for granted.

    A lot of people comment on this forum that it's a better environment for the complete technophob than most other Computer forums on the net. Due to the fact that we presume the op knows nothing about computers.



    Grim Post-Ironic Tip Of The Day 4: Kinda funny how you called me pedantic after posting such an in depth article :D


  • Moderators, Technology & Internet Moderators Posts: 18,377 Mod ✭✭✭✭Solitaire


    I apologise for that first post. I was being irreverent but currently being in a ****ing warzone here ( :mad: ) I ended up posting something that everyone interpreted as an attack; not my intent. My bad :o

    Having said that, I do have issues...
    You should really read the first post dude. Seriously.

    I read and re-read the topic. Nothing in there about how old and misleading some bits of it are. Not your fault - the PSU OEMs have changed dramatically since it was made! - but that highlights the issue that it could convince people "Ultra Good, Corsair Bad!" when the very opposite is true and Ultra somehow managed to make roughly one decent PSU before retiring and becoming PITA patent-trolls :rolleyes:
    And exactly how would it be breaking my heart?

    Because it looked impressive - I thought you put some effort into it! :D
    Grim Post-Ironic Tip Of The Day 2: Read the thread before making stupid comments.

    Ow. That's a bit unfair. And I'm not criticising you or the concept. Its just missing so much relevant, recent, info... :(
    Does he wear his knickers on the outside?

    HEY! STOP STALKING ME!!1! AND TAKE DOWN THAT GODDAMN WEBCAM!! :eek:
    And in fairness, mod or no mod, nobody should be coming in a attempting to ruin a thread for no good reason.

    But I wasn't intending to, and if I didn't point out the whole "old" bit someone would... I'm hoping you wouldn't react so angrily toward them in that instance (I on the other hand deserved it after that good case of Foot-In-Mouth up there :D)

    Absolutely not. Sorry, if there was genuine contempt directed toward a user because they're not a regular contributer I'd step on the antagonist. Hard. The problem is that a good few of the PSUs up there are old, others are server-grade and yet others have poor availability over here, are overpriced, or are considered to be in the wrong tier by even JG. Pricing and availability are wildly different in Europe and there are a lot of noticable absences on the old list due to age.

    There was the idea of a new list mooted on JG not so long ago... not sure what came of it :o

    Effluo - in fairness, if a user was savyy enough to install two HD5970's, and even want them in the first place, a certain assuption of knowledge is allowed.
    Kinda funny how you called me pedantic after posting such an in depth article
    That doesn't make any sense...

    Catering for the technophobe is absolutely no problem - I do it on a daily basis in work. If anyone needs to know something, all they have to do is ask :)

    Solitaire - apologies if my retorts were a little on the harsh side :o

    However, I will take a quote from my first post on this thread:
    I'd like (if I may) to post a post I had originally posted some time ago on another site which I had taken information from various sources in relation to PSU's & recommendations.

    This is quite an extensive list (but may not include every supply, so if yours isn't there, don't worry!), and I do need to update it, but it should at least give forum members idea's in relation to the best brands and ranges that your hard earned money can buy in relation to PSU's.
    So in my defence, I did outline that the list needs updating and that it is from some time ago, but it should give a decent enough reference as to what brands / models should be looked at.

    As some of you may have read in the Graphics forum I had my Corsair TX750W psu blow 2 weeks ago after only 18months. I'm in the process of rma'ing it now. It took the mobo out with it as I can't get it to power on with another psu. It was powering a lot, specs in sig with overclock, 5 hds and a good few usb devices, but should have been well able for it. I always thought I was safe buying a Corsair, just goes to show.

    At least I got a 7 yr warranty, but it cost fooken €38 to post as it was 2.7kg and now its stuck in Heathrow on the way to Corsair in Holland :mad:


  • Registered Users Posts: 7,692 ✭✭✭Dublin_Gunner


    Yeah I think I replied to your thread alright. Thats pretty nasty. The unit obviously did not have OVP, or at least it wasn't working and there was a problem with the unit as soon as it left the factory.

    Its recommended on jonnyguru, and I've recommended them myself before.

    I think you're just unlucky.. :(


  • Closed Accounts Posts: 26 Vergast


    hey hey,
    Just wondering you guys seem to be quite knowledgeable in the PSU department. Anyone , heard of this brand? or anything about this?

    http://www.komplett.ie/k/ki.aspx?sku=337116

    I'm contemplating a i7 rig and this is a nice way to cheapen the whole thing but Im really not up for buying a dodgy power supply. Thanks in advance for anything!


  • Registered Users Posts: 7,692 ✭✭✭Dublin_Gunner


    Hi Vergast, no offence intended, but you're a prime example of someone that tries to skimp on the PSU.

    Let me put it in perspective, you'll spend 100's or 1,000's on building a new rig, but only €50 on powering it?!

    The PSU, in my opinion, is the single most important component of any computer - do NOT skimp, you will be sorry.

    Anyway, I don't know what you have in your system component wise, but for around the 600/650W range as you'd selected, I'd recommend these:

    Corsair HX 650W €115
    http://www.komplett.ie/k/ki.aspx?sku=492649

    Coraisr HX 620W €109
    http://www.komplett.ie/k/ki.aspx?sku=327672

    I obviously only picked ones from Komplett, as you posted a link from there so I'm assuming you're buying all your kit there!

    650W good quality PSU should be well powerful enough for a Core i7, 4-8gb ram, single high end vid card type set up.

    ^^ exactly, Corsair, Thermaltake, FSP etc. are great brands.

    Heres a load of info on what PSU's to avoid and what are good/or cheap decent ones - http://forums.guru3d.com/showthread.php?t=287485

    Again, no offence to the OP, i just mean in general as i see this a lot, but why do people in general think its ok to spend 800 or 900euro on a PC and 30 euro on a PSU?

    A lot of folk here will disagree with me, but each to their own, i get the best/largest wattage/volts on the rails/highest effeciency psu that i can get and that will last me for 5 or more years( with a guarantee for 5 years also of course ), saves on my build costs as i only have to replace mobo+cpu+ram rather than the whole lot( i.e. i do the same for the case and screen )


  • Closed Accounts Posts: 26 Vergast


    Hi Vergast, no offence intended, but you're a prime example of someone that tries to skimp on the PSU.

    Excellent! Thats exactly what i wanted to hear! I originally had a Corsair but I felt I couldnt justify spending so much more until I had a good reason to . Now i do! And no offence taken, I asked for a reason!

    Stability is more of an issue for me than overclocking, maybe take the 920 to 3.0Ghz but not much higher. And Im not much of a gamer so my GPU will probably be a single gtx 260 or 275. As such Im thinking the 550W may be more suitable than the 600w I was initially thinking.

    https://www.komplett.ie/k/ki.aspx?sku=339898

    Although as lmimmfn said, would be an investment to go for the higher wattage psu.

    PS, anyone know of a nice place to get a gtx 260?? near impossible to find a good one nearby

    Dublin Gunner, the point of what i was saying is that, having words such as "SLI ready" is still not the greatest thing to put on any psu. For the fact which you have acknowledged "that some people just don't know".
    And most people on this forum don't know either!
    Just like Vergast here!


    Also there is nothing wrong with spending 40-50 euro on a psu and for 90% of users that is all they need to spend.

    For instance what is wrong with this psu?
    http://www.komplett.ie/k/ki.aspx?sku=404885

    It certainly would do for Vergasts needs or would come close! It is pointless to spend more unless Vergast has a will to upgrade the gpu or go sli in the future!


    Also i'm also confused to why Solitaire had to apologise for his post? Maybe it could have been interpreted as being a little condescending, but anyone who knows Solitaire knows it was not meant to be.
    "Grim Post-Ironic Tip Of The Day:" It's a sad day when someone can't incorporate a little bit of humor into their posts just in case someone might take it up the wrong way!

    Not to mention while someone labels someone else pedantic because he has a valid point on why he could reconsider a heading and some info on the psu's for the good of the general person who might be looking at his post.

    while thats a decent enough psu, its just going to limit any future upgrades, 30A on the 12v rail is just about cutting it for now for any cpu overclocking + an nvidia 260 or 4870, anything above that will be cutting it very very close.

    It is up to the OP whether to buy now to prevent having to get a psu upgrade whenever he decides to upgrade the gfx card, but gfx card power requirements are going only one way and thats up.

    Heres a great chart on gpu power consumption - http://mark.zoomcities.com/images/gfx/GFXpowerchartbybrandgen.png

    Unless a psu is one of the generally recommended branded psu's i would highly recommend never ever getting such a psu.

    if you'd like it as an investment you should say so as it changes recommendations, e.g. ive had 2 psu's in 6-7 years( across 4 PC builds ), and the current one should last another 3, i.e. do you think you'll ever have a dual card solution? even if its an ATI + nvidia combo for physx?


  • Registered Users Posts: 2,614 ✭✭✭BadCharlie


    @ Effluo : the PSU you linked is good as its a well knowing brand. But Vergast never gave the spec of his computer. And Dublin_Gunner did say in his post that he did not know what Vergast had in his system... but would pick the same wattage area as what Vergast linked in his first post (630watt PSU). So hence why Dublin_Gunner linked a 620watt + 650watt PSU. Im no rocket scientists but i can follow Dublin_Gunner logic here.

    Weren't the more recent nVidia drivers disabling physX where ATI cards were doing the rendering though? They may well have reversed this policy in the meantime, I haven't been following it recently.

    The official driver do indeed disable but you don't have to use the official drivers to make said setup work :)

    Due to a small change in components, gtx 275 instead of 260 and another hard drive I decided to get a 650W PSU. Currently im looking at the Corsair TX or HX, but Im not entirely sure the difference other than the HX is supposidly better. Any one have personal experience with either?

    I have the TX 650W myself it a very nice piece of kit IMO, good quality and dead quiet. The closest HX comes in a 620W model and is modular, also it is an improved design* (©Solitare in the other thread). So I am sure there are small efficency gains and other improvements as well.

    Get the HX if you want modular cabling but the TX range will not disappoint if budget is a restraint.
