1 out of 5 eggsLook elsewhere

Pros: Specs on paper look good for the price.

Cons: Used it for about 2 hrs to install some software on a new pc build. Loud pop and the smell of burnt wires just as I was finishing up for the night. I knew after reading the reviews I was rolling the dice. Looks like I rolled snake eyes. RMA'd it (Newegg was awesome) and spend a little extra for a quality unit. Unless you like to gamble, avoid this product.

5 out of 5 eggsBeast

Pros: This PSU is a beast for gaming. Works so good! enough for my AMD 8 core vishera.

Cons: Don't serve dinner.

Other Thoughts: MAke sure u give enough power to your PC, I had to replace my backup UPS unit cuz was a cyberpower 1350APR 800W and my PC shuts off randomly while gaming. I ordered a new UPS (((CyberPower Intelligent LCD Series GreenPower UPS CP1500AVRLCD 1500VA 900W 8 Outlets UPS))) unit giving my rig 900W and my PC is running excellent.

4 out of 5 eggsstable power

Pros: Still strong and stable after 18 months. Quiet, modular, efficient. Most cables were a perfect length for a full atx tower.

Cons: 12v 4 pin MoBo connector wasn't long enough to route from bottom mount PSU through the right panel cable management system in my full atx tower without pulling tight. Had to buy a 6" extension to relieve the tension. If that cable was 2" longer I would have given 5 stars.

1 out of 5 eggsDO NOT BUY

Pros: None

Cons: This power supply just won't work right. The one I received worked fine for a few days before suffering from surge problems, and now causes my system to crash when doing high performance tasks.
