Will my PSU support a EVGA Superclocked GTX 770?

Hey Guys,

As I said in a diff post, I'm upgrading my GPU to a EVGA Superclocked 2GB GTX 770. It's currently on its way...

On a review of the card, I saw something that said that the card needs "42 amps on the 12V rail" from the PSU...

Honestly I have no idea what that means, or if my PSU can support it.

I have a Antec HighCurrent Gamer 750W (Non modular) PSU. - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Do I need a new PSU or am I good to go?

You're more than good to go. That PSU will likely even support 2 GTX 770s.

However the PSU only got 40 amps per 12v rail, but I don't suspect it will let you down. Antec usually make some decent PSUs. A guy on Newegg mentions that he can run two GTX 570 with no issues whatsoever. GTX 570 uses more power than a GTX 770, so as mentioned before, you're pretty much good to go.

Best solution

Ya would need 600 watts for the system and 1st GFX card, add 230 watts for the 2nd so it's a bit tight for SLI on that PSU, but 1 GFX card will be fine.

The HCG-900 only handles 850 watts on the 12v rails or 70.8 amps. So if you going 2 cards x 42 amps, that would be 84 amps.
