Hi Guys,

I need help trying to figure out if my current build has enough power to power up a new graphics card I would like to buy.

Current setup:
CPU: i5-3570K (not overclocked)
MB: Asrock Z77 Extreme4
RAM: Corsair Vengeance 16GB (4x4GB)
SSD: Corsair 180GB Force Series
CASE: HAF X (I think it should be big enough to house it)
PSU: Corsair Gamer Series GS700 700w

I just need to know if I will need to get a more powerful PSU to run the Gigabyte GTX770 OC 4GB graphics card.

Thanks,
Craig

The 770 needs a minimum of 600W PSU to run according to Nvidia, so you should be okay, unless you want to overclock CPU. If you want any overhead though, it may be best to get a new PSU when you can - 800W or so.

If you take a look at http://www.anandtech.com/bench/product/829 you will notice the 770 using less than 400 watts from the wall. You are more than fine. They also have a pretty beefy test rig.

I know my own 3570k with a 670 will pull about 310 watts from the wall, so if you added 50 for the 770 you'd be at about 360. Again, your capcity is way over your usage.

You will be fine even with an overclock, you PSU is more than enough. I dont agree that you would need an 800w.
