PSU Recommendation

Crash Override

Hi,

My current PSU seems to be flaky or on it's way out in some degree (see my thread in Computers & Technology for more info [PSU Power Surge and BIOS access issue].

Just wondering if anyone has any reccomendations on a suitable PSU upgrade given the specs below:

System Info
Motherboard: ASUSZ87-Pro - BIOS Version 10.07 (05/17/13)
Power Supply: CoolerMaster V650 80+ Gold
Processor: Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz (8 CPUs), ~3.5GHz
Memory: 8GB Cosair Vengence
GPU: NVIDIA GeForce GTX 1060 6GB
OS: Windows 10 Pro 64-bit (10.0, Build 18363)
Other: 1 SSD, 1 HDD, 1 Disc Drive.

I did look up a few a while back but everytime I found one that was a good price and seemed like a good unit, I always found someone to say that the coil noise was awful for the unit itself was unreliable. A 650 Watt I would think should be enough to run everything I have currently.

Thanks in advance.

Firstly, it's a mistake to assume that more is necessarily better when it comes to rated wattage, as a good PSU can provide more power for your components safely than a bad PSU, even if the bad PSU has a higher rated wattage. At minimum, you need to check the more detailed sub-ratings on the PSU particularly to see how much amperage it can supply on the 12V rail (or rails), while the 3.3 and 5 volt rails are typically less of a concern. Sometimes companies will simply call a PSU "650W" when it really shouldn't be used for anything like that:

You shouldn't need anything like 650W for that system. I put your specs (and a few assumptions) into an online PSU calculator and it came back with 367W recommending a Corsair 450W model.

It's always a good idea to over-specifiy your PSU a little bit, just so that it's not working flat out, for that I'd recommend a good 500W PSU. I'm a fan of Seasonic, hard to go wrong with them, so you might consider something like this:

500W, pretty much all of that available on the 12V rail, or if you want to buy from within the EU:

Thanks for the reply and informative response!

As you can probably tell from the components this rig was built many years ago back when I knew a lot less about the intricacies of PC building.I definitely did hear before that too high a PSU can actually be a bad thing - I didn't realise mine was way over the recommended level.

I get a "ASUS Anti-Surge Was Triggered to protect system from unstable power supply unit" every once in a while (no graphics card and not playing games) and I get it very frequently when I amusing the GPU and playing games with it.

I just checked my current PSU and it can supply 54A to the 12V rail apparently.

Thank you for the suggestions too, I'll have a look into those!
