PSU recommendation please

skyqpic · 23 Mar 2016 at 13:37

Hi,

I am struggling to choose a PSU among the following 4...

1. Corsair RM850i
2. Corsair HX850i

3. EVGA G2 850W
4. EVGA P2 850W

All of them are tier 1 PSUs and RMi series seem to have solved issue in the origial RM series...difficult choice.

Corsair has a Corsair digital link...is it useful?

Thank you very much.

What system are you trying to power? If you're looking at 850W units, I'm guessing you've got SLI/Crossfire.

The EVGA G2/P2 units are made by Superflower and are very good. The price is similar to the Corsair units, which are also good units.

I don't know how long the Corsair warranty is, but the EVGA units you're looking at have a 10 year warranty, which is very good. EVGA's customer support is also supposed to be very good, although so far I haven't had to use it!

Hi,

I am building 5820k+GTX970 SLI...

but just realised that 5820k + SLI will only work at x16+x8 mode...so not sure if I am getting anything from SLI...so 850W is kind of just for future proofing...

Corsair gives 7 years warranty I think...

I was debating the same... ended up getting a 1000w EVGA and been happy as a pig in the donut shop!!

x16/x8 SLI will be fine. I don't think you'll notice the difference unless you're benchmarking. You need a 5930K or 5960X to get x16/x16. 850W will be more than enough for 970SLI and OCing the 5820K.

I would go with a single 980 ti over 2 x 970's.

EVGA and a single 980ti. Why tempt fate with possible additional problems from using a pair of cards when you can have a single powerful card?

I was going to suggest a 980Ti, but wondered if the OP already has two 970s.

If the OP is indeed buying everything from scratch, then a good 550W would be fine, 650W if they want some headroom for OCing. You don't need obviously don't need 850W for a single card setup!

Confirm, RMi/RMx and HXi PSUs have 7 years warranty.

Any one has experience with Corsair ones? How useful is that Corsair link software?

It's a gimmick and can be buggy from what I have read on here. Why does anybody need to see what a psu is doing? As long as it does what it's supposed to do is good enough for me.

Because the idea of "control" over components appeals to some people...

People shouldn't have any control over a psu apart from the choice to run the fan in eco mode. Most people have no idea how a psu works so should leave it well alone. As long as it does what it's supposed to do there is nothing to worry about. We still see people building high end pc's and then stick a £20 psu in it and then wonder why things go wrong. I can see right now what would happen if people like that were able to control a psu.
