SLI GTX 770 4GB FTW requirements (42A on 12v)

xj220falconx · Sep 29, 2013

Hi everyone,

Im thinking of upgrading to 2 GTX 770 4GB FTW in SLI which both require 42Amp on the 12v rail to work properly. I already have at home a Corsair HX1000 and a corsair HX 850 at my disposal.

The HX1000 has 2 12v rail of 40Amp and the HX850 as a single 12v rail of 70Amp

Will one of those PSU will be enough to hold both 770s in real life gaming?

Thanks!

Either will. It is combined amps they are meaning and it is for the total system with one card when they specify requirement. SLI calls for 850 watts http://www.realhardtechx.com/index_archivos/Page362.htm

Each GTX 770 is a 230W card at max. That is 19.2 amps on the +12V rail per card maxed out.

Either PSU is more than enough.

And what would you choose between a 3yr old HX1000 and a brand new HX850?
Does the HX1000 performances dropped over the years?

Thanks for the earlier answer!

If I had them both I would use the HX1000 which has not lost that much of its performance if any, if I was buying I would get the new HX850.

If you already have the HX1000 and it is functioning properly, use it. I can't think of any reason not to. It's already way more PSU than you need for a pair of 770s.
