Corsair Gaming Series GS 800w


Big thank you to CryoPC for providing the following test rig:

CPU: Core i5 750 @ 4GHZ
Motherboard: Asus P7P55D-E
GPU: Sapphire 5850 1GB
RAM: Corsair Dominator 4GB PC3-12800 DDR3
Storage: Samsung F3 500GB 16MB 


Here at XSReviews, we don’t have the money for a full test bench when it comes to PSUs. Load testers cost thousands of pounds which unfortunately we just don’t have. Because of this, we don’t pretend to test the rail stability or efficiency of a PSU, as we simply can’t do it effectively.

However, what we can do is test the Ripple/Noise quality of each rail using an oscilloscope. The one used was USB Instruments Stingray DS1M12 using HP 3060 probes and also in line with ATX specifications, I used 10uF and 0.1uF capacitors to simulate added load.

Noise / Ripple Results

For a rundown of what noise/ripple is and why it’s important to test it, check out my last PSU review here.

The figure to note in the following images is the peak-peak voltage, the second reading.

All these ratings are perfectly acceptable, so there should be no hazards with using this PSU.


While this is far from a complete test of this PSU, it does show that there should be no issues with Noise/Ripple. I’d urge anyone considering this unit to check out some more in-depth reviews for efficiency and overload tests, but we can confirm that there are no safety problems with this unit.

The added lighting effects are pretty nice – even if the adjustment button is a bit close to the power switch – and the build quality feels solid too. On top of this, it’s pretty quiet, since the fan only engages when necessary. More than happy to recommend this unit for mid-range enthusiasts and gamers. Just a bit of a shame it’s not modular.


  • Passes all noise/ripple tests
  • Solid build quality
  • Nice lighting effects
  • Quiet, fan only coming on when needed


  • Not modular
  • Annoying screw heads
