Solved Power supply for GTX 770 Last response: June 2, 2013 9:03 PM in Graphics & Displays Share austin4189 June 2, 2013 7:57:51 PM 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. PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168... and here is the 770 just in case. http://www.newegg.com/Product/Product.aspx?Item=N82E168... thanks for the help in advance More about : power supply gtx 770 Best solution cookybiscuit June 2, 2013 7:59:43 PM Yuppers, good to go. Share Bezzell June 2, 2013 8:05:59 PM 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. m 0 l Related resources Is my Power Supply Enough For Hi,I want to buy EVGA NVIDIA GeForce GTX 770 Superclocked w/ACX Cooler ? - Forum Gtx 770/ Gtx 760 power supply help - Forum gtx 770 super clocked acx power supply - Forum Gtx 770and my power supply - Forum Power supply for 2 way gtx 770 - Forum Can't find your answer ?

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... m 0 l Bezzell June 2, 2013 8:16:58 PM 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. m 0 l cookybiscuit June 2, 2013 8:19:45 PM It's Seasonic so I'm sure it will be fine. m 0 l austin4189 June 2, 2013 8:21:44 PM 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. m 0 l Bezzell June 2, 2013 9:03:13 PM Yep, you're good to go. m 0 l Can't find your answer ?
