5 out of 5 eggsLasted almost 6 years! Amazed.

Pros: Bought this in March of 2008 for a first gaming rig. It advertised support for up to a 8800GTX. Originally powered a 8800GTS, and has been the motherload to many other cards. In 2013 (5 years later) I purchased a GTX650, and only now in January the PSU started powering off from a lack of available power to the GPU. Impressed with a continuous almost 6 year performance, would highly recommend Rosewill's PSU's regardless.

Cons: Fan louder than expected, generates a considerable amount of heat.

Other Thoughts: Will purchase Rosewill again!

2 out of 5 eggsRan Great - then melted my power cable

Pros: This was a great and reliable power supply for well over a year.

Cons: After I recently purchased another graphics card to run SLI, I kept smelling something funny when I was playing BF3. I couldn't figure out what it was until I looked at my power cable which had practically melted completely off. Now I need to get a new PSU.

3 out of 5 eggsDead after just over 3yr

Pros: Looked pretty. Would say it ran good, as rated but I never pushed it. i always like ot buy my PSU's with more power than I will ever need as they are generally more efficient that way and alst longer.

Cons: my assumptions on it being overkill for my uses and thinking it would last MUCh longer than it did were wrong. This PSU now immediatly 'winds down' when I engage game play on a single 5830 video card. And will crash completely if I don't stop right away. I have 3 additional, verified working 5830's from other systems that all prove the same result. blue lits in PSU dim and system crash after a few seconds. =(

Other Thoughts: oh well, live and learn. I usually pay the bit more for PSU but this at the time seemed the best mic of price/performance. I was wrong.

2 out of 5 eggsGood... for awhile

Pros: Easy Install
Bottom mounted
850W
Netted cables

Cons: Died after 2 years of very mild use.

Other Thoughts: It was good, till it died. 2 year life is unacceptable, and I won't be buying this brand ever again for myself, friends, or customers.

2 out of 5 eggscheap brand

Pros: worked fine while it lasted

Cons: Payed 108, and it was dead just after a year.

Other Thoughts: Also the CPU power cable is short. Barely reached the other side of my mobo. Guess you can get a case that doesnt have the psu on the bottom of the case....

1 out of 5 eggsNot built to last

Pros: Cheap. Bought this back in '09 for 90 bucks not a big loss

Cons: Failed just after a year of moderate use.

Other Thoughts: The powersupply created rolling waves in monitor last few months before it died. Very annoying determining the cause because i thought it was a house ground issue for a while, and it was distracting while playing games.
