Hi guys just finished my first ever build and I am very proud of it (thanks to you guys). Now that it's up and running I want to install a graphics card. I think I'm going to go with http://www.amazon.com/GDDR5-technology-Graphics-Cards-H.... Anyways, I've used psu calculators online and they just don't seem to give me a legitimate answer. They keep telling me I only need like 380W. So here are my components.
Case: Phantom 410 (2 120mm, 1 140mm and 30W controller)
MOBO: AsRock z77 Extreme 4
CPU: intel i5 2405s (65w)
PSU: 600W diablotek
Those are the main power suckers. And I don't plan on overclocking. So do I have enough power?
What you have doesn't use a lot of power. You have a 65W CPU and the 7770 uses less then 100W. (80 something I think.) Your total power draw would be 200W or less.
That said, whoever suggested you buy a diablotek PSU wasn't giving you good advice. I have yet to see a single PSU from them survive any real testing. As such I don't suggest people use them. Return if possible and get a better one. The Antec 380W green or the Corsair CX430 should power that setup just fine. The 7770 just doesn't use a lot of power.
