Works Great

Customer review by VMD2B

I have been using this power supply for two years now and it has been working great. I cannot even hear it running unless the room is completely silent and I am listening for it. I have a Nvidia GeForce GT 520 graphics card and this PSU is more than enough to power it even when I am playing games. It was also fairly easy to install and fully works with my HP computer with Pentium Dual-Core CPU.

Customer review by Fishnndude

2.0 stars by Fishnndude

The description of this item states it will connect to AMD motherboards and accessories and while it did connect to my motherboard it would not connect to my disc drive which made this unit useless for me. Also the unit states it is a 400W unit when it is actually 375W. And lastly it said it comes with a gold plated fan guard for excellent heat dispersal but it was just a regular chrome or nickel plated (not a big deal but if they make a point of mentioning it in the item description then thats what I should get).
