Corsair GS800 Power Supply Review

Conclusions

The new Corsair GS800 is a terrific power supply for its price point, and we highly recommend it if you are looking for an 800 W unit with a good cost/benefit ratio.

Even though it only has the standard 80 Plus certification, we saw efficiency up to 85.7%, and we could pull up to 1,000 W from it (even though under this extreme condition efficiency dropped a lot). Voltages were closer to their nominal values than required (3% voltage regulation), and ripple and noise levels were below the maximum allowed.
