Worked with out and issue for 2 years 11 months. Failed exactly one month prior to the warranty running out. I run my PC 24/7 365 days a year. RMA process was easy Shipped back on a Monday. They received it on Thursday and ship the replacement on...

Works Great


BF bought the 850W version recently to replace a shot power supply and it works like a charm as well. Also, it comes with a nice velcro wrapper for the body cords and several black zip ties. Nice touch.

Haven't had any issues with this power supply yet. Love that it is modular, it runs great, never gets too hot, and I haven't had any issues so far

Wish there were less cords, but that's not really the power supply's fault

Crapped out after 5 months


Was on sale for $90. Still too steep a price for a 5 month lifespan. 5 months of use is maybe worth $30. If you're looking for a 5 month solution for only way too much money, click "add to cart" now!

It supplied power for 5 months

It only supplied power for 5 months. Started acting up after 3 months, cutting power occasionally. Finally died after 5 months

Good PSU While it Lasted


Worked perfectly on the day I got it for about four years until it began to break down

A little disappointed it started to breakdown about four years since I got it. I have other brand PSUs such as Antec and Thermaltake which still operate fine 5+ years. The PSU started to breakdown everytime I would turn on my PC, it would make abnormal...

loud and unstable


if you get one of these, be sure to get the replacement plan with it, I made the mistake of not getting any kind of warranty and now I'm stuck with an 850W paper weight. Not going to buy a Rosewill PSU again.

Nice size to price ratio. Looked pretty sleek when I unboxed it finally

It took me almost six months to get the rest of the computer and when I finally got everything and put it all together this one didn't work correctly. I had it in a simple setup with an AMD A10 6800K, asrock hudson board, and two harddrives. At first I...

Decent power supply

PAY ATTENTION TO THE AMPS!!!!! I'm sure this is a dependable power supply, but it only puts out 20 amps on the 12v rail. Newer video cards, including mine, require at least 24 amps. My computer would automatically restart when my GPU needed to draw a...

Not recommended


I build my computer for gaming, and this psu was running the moderate games I was playing. As soon as I started playing demanding games, it would surge after 15 mins of game play and reset my computer. There is no reason this psu shouldn't be able to...

Lots of connections ; Quiet ; Nice LED

Can't handle the load ; Gets "power surges

It Works


I still have yet to buy a modular psu. It would have been useful for this build to keep things a little neater.

Has all the connections I need and then some

The 8-pin cpu power connections are too short to run behind the motherboard. I will have to buy an extension or just leave it weaving across the top of the motherboard under the video card
