New power supply

Chrisbes · 2 Dec 2016 at 12:21

After coming to the conclusion that my power supply is producing an awfully loud whine when games are played, I'm in the market for a new one. Specs are as follows:

I7 2600k @ 4.5ghz
Asus P8Z68-V Pro
4 x 4gb Corsair XMS3
MSI GTX 1080
2x 3.5" harddrives
2x SSDs

Currently running an old Corsair TX850 but I definitely don't need 850W anymore as I'm no longer running SLI and probably won't upgrade for a while. If I do, It'll be a smaller motherboard and probably an I5 so that's not a power related problem.
Requirements are only that it'll fit an MATX case and that it's fully modular and it's the best unit anywhere up to around £120.

On the short list are the following (In no particular order..) :

SuperFlower Leadex GOLD 650W
Corsair RM650X
EVGA SuperNova G2 650w

Any suggestions?

The EVGA Supernova G2 650w is built by Superflower and is basically the Leadex Gold 650w with a different fan, no led's and a longer warranty at 7 years. All three of the ones you listed are top quality units but the Corsair RM650X has the longest warranty at 10 years.

The Superflower Leadex Platinum 650w is in the same price range as those three as it's on offer at the moment for a cracking £95. Just keep in mind that all Superflower Leadex models have bright white led's where you plug the cables in and they cannot be turned off.

Also worthy of consideration is the new Bitfenix Whisper series. They are keenly priced and have a 7 year warranty. It's a CWT built unit with quad 12v rails. Each group of components has it's own rail so 12v1 is for Motherboard + Peripherals, 12v2 is for CPU, 12v3 is for GPU 1 and 12v4 is for GPU 2. The full 650w is available across the 12v rails. Review of the 550w version here and the 850w version here.

I'm not against going for a 750w+ unit if the quality is better. Looking at the pinned guide, it seems as though the 750s and 850s are better quality?

I ended up with the EVGA G2 650W PSU and it really is of great quality, prices has increased a bit since I purchased, but if I had to go and buy another one tomorrow would I?..I think so..

Picked up an EVGA Supernovea G2L 750w. The psu doesn't whine anymore but the gpu still does. Shame
