What Power Supplies should I look at?

post #1 of 17
Thread Starter 
I'm going to be ordering my system very shortly (once Sandy Bridge is released). And, I want to make sure I have everything planned out before the 9th.

With my limited knowledge on computer hardware, I've been asking the overclock.net forums for a lot of advice. With most of my build completed, I just need a few more things. 1. being a power supply.

Here's my build.

Cpu: i7 2600k
Mobo: Gigabyte U5
Gpu: eVGA GTX 570 (Will be adding a second gpu in the near future)
Memory: Undecided
Psu: Undecided
HD: Samsung F3
Cpu Cooling: Undecided
Case: Raven RV02-W

I want to add a second video card. And, I do plan on overclocking.

The power supplies I have been looking at are a AX Corsair's and Cougar's SX 850 http://www.newegg.com/Product/Produc...82E16817553006.

Will 750-850 wats be enough? Should I look into the 1,000 range?

Thanks.

You need a quality 750W.

Tier 1:
SeaSonic X750, SeaSonic X760, Antec HCP-750, Corsair AX750,
Tier 2:
XFX BE 750W, SeaSonic S12D 750W, Corsair HX750, PC P&C Silencer 760W
Tier 3:
Silverstone ST75F-P, Antec TruePower New 750W, Cougar S700, XFX Core 750W
Tier 4:
Corsair TX750, Corsair GS800, Antec HCG-750, PC P&C Silencer 750W, PC P&C Silencer Mk.II 750W, OCZ SXSII 700W




Any of those would be more than ample and you would likely not see any difference in performance with any of them; you definitely would not see any difference with Tier 3 and above.

A nice 750W will do. What is your budget?

You may have to check the connectors for the PCI-E but I'd recommend Seasonic stuff if you have the money.

The one you provided in the link looks like it should do fine. But I think this is in the same price range a a single rail is something I'm more comfortable with.

Agree with previous two posts. A solid 750w psu can do 60a on 12v should be fine. Both 850w psus in your link can do 68a on 12v so it give you some headroom in case you add WC or other components.

I might add a water cooling system in the future. I'm not 100% sure yet.

I'll look into all of these. Thank you.

Where does Cougar rank as a company? I really like their color scheme. It's different. However, I don't want to sacrifice too much performance for it. They don't really sell themselves to an American market, but they still sound like a good company.

I guess right now it's a toss up between SeaSonic, Corsair, and the Cougar I posted.

Cougar are basically rebranded HEC units.

The S700 is not a bad PSU.

In fact, it's probably amongst the best of its time, but the other Cougar ones are just mediocre to average.

They are probably some of the best things from HEC we've come to see.

The AX-750 is a very good PSU but a little expensive! The best brand is Seasonic X-series but if the price is right you could check the Corsair HX-850w.
