Corsair RM850 vs Seasonic 850W

[Spinny99]

Hi everyone. What PSU should I get between these too (I'm looking for SILENT, Fully Modular, And able to support my SLI 660ti's.

I've boiled it down to these too, they get good reviews and seem really nice:

Seasonic 850W 80 Plus Gold ATX12V/EPS12V Power Supply - X-850 SS-850KM

Corsair RM Series 850 Watt ATX/EPS 80PLUS Gold-Certified Power Supply - CP-9020056-NA RM850
http://

Please help me decide!

Both are good but I would go with the Seasonic.

Is there a particular reason the Seasonic over the Corsair?

I would also get the Seasonic. Seasonic has never made anything poor quality but Corsair has some questionable quality units (Cx line). Simply supporting a better company.

Build quality. Seasonic is arguable the best PSU manufacture around. The Corsair is made by Chicony Power Technology, good but not as good as Seasonic.

I believe the RM-850 is a unit made by another oem manufacturer, either flextronics or delta. I would go with the Seasonic as it is rock solid unit, the rm 850 is still relatively new, and their track record is top notch.

I would guess that Corsair PS was either made by Seasonic or Channel Wells. Both are good I would think.....

That is true. I'm just astonished by the reviews on the 850w, and I'm a long time corsair customer. I've never bought anything from SeaSonic before. I'll keep looking into it, but I'm leaning toward the RM850.

You guys think I need 850w or 750w:

750w is plenty for that build. Anything more would be overkill.

2 gtx660 ti's will only use 270w MAX under FULL load.

Alright thank you. I'm going with the RM850w for the extra modular cables (even though it's overkill). It's supposedly dead silent, and has great reviews. I can always return it through amazon and go with the Seasonic if that is wrong.

Thanks for the help everyone!

I would have gotten a 750w unit but 850w won't be bad or anything.

The RM series is made by 2 different OEMs the 450,550,650 and 1000 are made by CWT(channel well) and the 750 and 850 are made by Chicony Power Technology.
