Corsair VX450W
Efficiency is definitely one of the highlights of this product. Corsair says this power supply achieves a maximum 85% efficiency, but they are wrong – in a good way. The only time this power supply achieved efficiency BELOW 85% was when we pulled 450 W from it (84.3%). On all other tests efficiency varied between 86% and 88%. Amazing. Just to put things into perspective other entry-level power supplies can’t even reach 80% efficiency, and the ones that can they don’t reach 85%.
eto ti cijeli test...
