Power supply for GTX 770

austin4189 · Jun 2, 2013

I am upgrading to a GTX 770 and i was wondering if this power supply will suffice. My main worry is the amps of the 12v rail it doesn't say on the graphics card but it need minimum 42amps on the 12v rail.

and here is the 770 just in case.

Yuppers, good to go.

I believe you need 42 amps on a single rail. The seasonic you linked is 2 rails, 24 amps each. Even if both 6 pin vga cables are each on separate rails, it'll be cutting it close.

I'd get a single rail PSU. Preferably with 2 x 6+2 pin connectors, as you need two of them for the 770.

ok thats what i was afraid of :/. But I've had a GTX 480 which has identical power requirements and everything has been running fine for over a year so im kind of confused at the moment...

If you own that power supply already, give it a try, probably will work fine. Just will have to use one of the 8pin adapters that come with the card. I thought you were shopping for a new one.

It's Seasonic so I'm sure it will be fine.

The 770 requires a 8 pin and 6 pin, am i wrong? Also my PSU has a 6+2 which = a 8 pin. And my psu has a 6 pin so i dont think i need to use any adapters.

Yep, you're good to go.
