850 watts. 80+ bronze

Not a con but this thing is HEAVY compared to other power supplies I've owned. The blue light is also a weird shade of blue almost like an aqua blue or slight turquoise color, also it's not the brightest either

Dead after 2 years

 

This is my second Rosewill PSU to have died after only a couple of years. I do not recommend this brand. This PSU ran fine while I was using a HD7870. It should be fine for last generation gaming rigs. However, I just bought a new GTX970 and the PSU...

It was a solid PSU while it worked. Ran cool and quiet

Died after two years

"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
