Corsair GS800 800W Power Supply (Page 5)

Test Results

Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.

The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are greater than the Corsair GS800, we can test it to the maximum.



With the exception of the 5V rail, the GS800 performs quite well for a mainstream power supply. Unfortunately the 5V rail started out low, was out of ATX specifications halfway through our testing, and only got worse as the load was increased. Noise on the 12V rail was also higher than we like to see, but it is still well within specifications.

I went back and re-ran the tests with multiple multi-meters just in case something was configured wrong or I had a bad meter, and the test results were the same.

Final Thoughts

Corsair gives you just what you would expect from a mainstream 800W power supply. Enough connectors are available for the task at hand, enough power is available for the mainstream gamer/entry level enthusiast, and the price is right for a retail unit. If only the performance was all within specifications, I would gladly label the GS800 as an all around good deal.

Unfortunately the 5V rail on the GS800 just isn't up to specs, literally. The voltages were low from the start and dropped fast as the load was increased. They aren't even close to borderline.

The rest of the power supply was spot on with what you would expect throughout the entire test. Power supplies are all or nothing when it comes to performance and unfortunately this one just isn't all there.
