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

Consumer review by:

A+ works great

 

Would buy it again

Gives ample power to all my drives and devices I have hooked up not to mention it looks nice for a power supply

Internal temprature of tower case warm not sure if video card or power supply or mobo/cpu not risking overclocking had to turn overclocking off it got so warm in my steel tower

I really wanted to like this thing..

 

I read many reviews on this psu before I purchased it and I have it a chance after seeing mostly good reviews. I wanted to like this product but sometimes I guess you just get a bad one. I'll probably keep it for a spare or a future lower power project.

Fan is quiet, lights add a nice touch to the computer

This psu only worked consistently for about 7 months. Recently while playing games, specifically Assassins Creed 4, my computer started randomly restarting. I figured out that my power level was dropping after a while and it would cause my computer to...

looks good and works great

 

high output for a low price, looks good with its blue led fan, tons of connecters

not modular

Consumer review by:

SIX AND A HALF YEARS and still going strong

 

I bought this right at the beginning of 2008. It has outlasted three computers, each of which used SLI and heavy water cooling and overclocking, I just keep putting it in the new ones. Nothing has rusted, the fan is as silent as the day I installed it,...

There are no cons. It's a perfect power supply

Consumer review by:

Long Lived and Still Kickin'

 

I purchased two of these in 2010 (4 years ago) for my computer and one for my sister. Both are still kicking and one of them I've just sold for a new upgrade. Have not had a single issue with these Rosewill PSU's. They are a great value and I would be...

Strong Steady Voltages ; Looks Great ; Lots of Plugs ; Plenty of Cable Length (mostly - see Cons)

The CPU 4/8 pin power cable could be longer. Had this bottom mounted in an Antec 900 and it was a stretch to reach the board connector

Consumer review by:

Failed after 7 months

 

This power supply started to cause my PC to reset constantly with no warning. At times it would work for normal use, but when a game was fired up, PC would restart. Heating is no issue. I ran many checks and constantly monitored. I replaced this power...

Quite

CPU power cable is not long enough for a full tower

Consumer review by:

Pleased

 

would buy again

price ; cable length ; molex - which i dont use, but if you did it has it ; plenty of extra cables for lots of components ; the sleeved cables are nice ; over a year use and still strong

not being modular is really only the con
