For performance we have a PSU which does well across the board. Readings are not up to the standard of Corsairs more expensive units but they still compare well with the competition and we were pleased to see the unit pass tests such as AC ripple with ease. Additionally, the GS800 also powered our Core i7 system with GTX 580 GPU without issue.
So that brings us to value, at £80/$120 the GS800 is priced appropriately and backed by a 3-year warranty and Corsairs standard support which includes aspects such as an active user forum.
A good PSU which will serve any gamer well should they not be able to afford one of Corsair's higher specification units.
