"Power Surges" Since GTX 980 installed

 

Might work fine with some computers. Just be careful, upgrading parts might make the difference between working and not working. It's up to you to roll the dice! I submitted an RMA. We'll see how things go with this faulty model. Still unsure if I will...

Worked great for quite a while with my GTX 680 installed! Didn't have any complaints

Upgraded to the GTX 980 which has a recommended 500W PSU. Know my rig would need some more so I grabbed this 850W which should be plenty. Now my computer keeps shutting down due to "Power Surges". Handles the GTX 680 fine which has a 550W recommendation

Ol' reliable!

 

I'd rather have too many cables than not enough. Still, it's never failed me and lasted for some time now. I highly recommend it!

Worked flawlessly for my system since 2012

Many many cables, and I have a smaller case, so cable management is atrocious

Great power, cool running,great price

 

I have used Rosewill power supplies a lot and just do not have problems with them and if you have a constant power demand then not having removable cables is a plus because each connection is resistance and with each connection comes more work and with...

Cool running, great power for price, I purchased 5 for projects I am doing

none ; I see people complain that they have all the cables attached.....you know that already ; Having said that if you are looking to do a pretty see through case to show off your build this type of power supply will leave cables hanging all over

Great!

 

saw someone review this and mention flipping the psu upside down to get the blue led to show in their case this would be bad for two reasons; you've now increased the heat in your pc greatly, and you've dramatically shorted the life of the psu by...

Stable power supply. certified even if it's only bronze. have two cross fire HD 6850s overclocked, X4 860k overclocked to 4.2 ; nice sleeved cords, blue led light which doesn't matter unless your case is on a shelf for some under glow. most cases mount...

only thing i can say is heat shrink on the 24 pin-power connecter doesn't cover enough, but most people won't care about that

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
