Rosewill RX850-S-B

 

I've disabled the surge protection in the BIOS so I'm 100% sure this PSU is the source of the issue. I would strongly recommend NOT buying this PSU if you are using a GTX970 or higher. The PSU may meet the minimum wattage, but it falls FAR short of...

Good wattage for the price

When faced with a powerful graphics card, this PSU routinely deems graphics draw as a power surge and forces the system to shut down to "prevent damage

No good Power Supply

 

None. First unit failed a month after I had it

This unit is flawed. Purchased the first one, did not power on at all. Returned. Received this one. Wanted to upgrade my 600W power supply to this 850 Watt. Powered on computer it ran for 2hrs before failing. This thing SUCKS

6.5 Years and still kicking

 

I turn off my computer every night, maybe that's why it has lasted me that long? Give your computer time to rest!

I have had no issues with this PSU. I bought it in July of 2008 and it has lasted through 2 machines. It handled everything that I have thrown at it. Had 3 8800GTS running SLI at one point, now running 2 GTX560s and bout to upgrade to a GTX 970

NONE

It will break within few months

 

If you're looking forward to buy a PSU for a single card, opt for a more efficient PSU, and you might as well throw a few extra bucks for a better quality product, it will payback on the long run.

The PSU is very efficient and handles Heavy Gaming like a charm, while it lasts

Owned the Power Supply for around 6 months and it worked fine until it started shutting down my computer as soon as I started playing a game or started a Graphic Performance test ; The computer will boot just fine, the temperature will be good,...

Computer restarts during games

 

I upgraded from a 350W supply to support my new graphics card, and there's absolutely no way the extra 500 watts are insufficient to power the card. I cannot at all recommend this power supply, especially for use in heavy gaming.

Quiet, has a pretty blue light

I didn't notice any issues until I started playing Borderlands: The Pre-Sequel a month after buying this. During any intense activity in the game my computer has a chance of immediately shutting off and restarting. There is no blue screen, no...

Disappointed =/

 

I wanted to upgrade my PC so I got this 850W to take over what my old 700W was doing perfectly and it cant. My airflow is good but this thing just doesnt like to work when run any games. If I stay on my desktop and dont do anything my comp doesnt...

looks neat when its working

When ever I try and run any game my comp powers off then restarts
