PC Power & Cooling Silencer PPCS500D 500W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply compatible with core i7

Pros: Much quieter than the stock Dell psu. I barely hear it. Pretty easy to install in my Dell Dimension 4700. Gives me enough power to upgrade my video card. Finally!! Feels well built. Cabling is good quality. Lots of connectors
35 amps on the 12v rail a plus. More than enough
Got it for 20% off original price

Cons: For me just a few more cables than I needed. Took a little extra time to route them in a proper manner. No biggie. Still giving it 5 out of 5

Overall Review: Dell Dimension 4700. Fits good. All screw holes lined up. No gaps at all. Had to take the rear fan out of the way to put this psu in. That was easy. My first psu install. Took me around 25 minutes. But most of that was just cleaning dust out of the PC . Actual psu install probably 10 minutes. Powered on and no problems so far.
This psu and the new video card will keep my dell 4700 going for another 2 years. If you have a 4700 and want to upgrade your card get this psu. You wont regret it.

Pros: It fits a Dell

Cons: The first power supply lasted a month. I returned it to new egg they sent me another and it also lasted about a month and stopped working. This power supply is not worth the money I spent on it. It is not quiet, way too many cables.

Overall Review: Will never buy another from this company
