Hello all!
I recently built a computer (http://goo.gl/HrP2Hw), and pretty much everything went fine, except GTX 660 I bought didn't work. I used the computer w/o the GPU, and recently I found out that I (stupidly) didn't do all of my research and the PSU I got was only 430W while the 660 required 450W. Anywho, I need to buy a new one and would like some recommendations on a solid one, probably 500-600W, right? Picking a PSU was a main choice for me b/c they getting a good one is key to a great computer.
Thanks in advance,

Hi - actually a sys with a 660 will run on a good quality (modern design) 430w PSU. I suspect you got an inferior PSU
I agree it looks like you need to upgrade.

The Silverstone in your linked sys is good, but for that $ you can do better.

If you have a Corsair CX430 (SKU# 75-001666 / CP-9020046) you shouldn't have any problem powering a system with a single GeForce GTX 660 (non-Ti) graphics card.

I don't know, it's probably a faulty GPU. The fan whirs but when I try to install the drivers it says it can't find any compatible hardware.

Did you plug the 6-pin portion of the PCI-E supplementary power connector from the power supply unit into the 6-pin PCI-E connector on the GeForce GTX 660?
