"In the end I found that, like I said in the beginning, this is to date, one of my favorite PSUs to use. Not only does this PSU look great with its bright LEDs, or for those that don’t like LEDs you can turn them off, but also the Kingwin Lazer 850W Performance Series PSU shows that it’s a powerful little work horse." - Reviewed OVERCLOCKERS HQ

"Most everyone prefers modular power supply because you don't have any extra unwanted cables to deal with. While the Kingwin LZ-850 850W Power Supply isn't completely modular, most of the leads are and the remaining leads are hardwired into the PSU. It has a very quiet 140mm white/Blue LED fan." - 3DGAMEMAN
