    What can one say about a PC Power Supply? It either works or it doesnt. This one does, and has an on-off switch.

    Its a decent basic 400w PSU which is fine for a desktop without a beefy grafx card. Price was right and I found it at retail.....if you need something with umph then go online!

    Purchased as a replacement to my PCs old power supply. Replace the power suoply myself, did the trick no issues. Just make sure you know what you're doing before you try this at home.

    My friends power supply unit went bad on her computer. I went to Best Buy and found this unit as a replacement. The unit was priced well and was easy to install. I was able to get the power supply unit installed in 15 mins and had the computer back up and running in no time. I would definitely recommend this product to friends.

    Installed this product to solve what I thought was a power supply problem after upgrading my GPU. Turns out it was actually a bios startup setting. Would definatley have kept this product if that would have been the problem. Removed the product and returned it for a full refund. Thanks Best Buy for your easy return policy!

    Works as expected. Typical 400W power supply. If you have other power hungry peripherals buy something bigger.
