no problems - works fine, very stable

Pretty good, could be better

Significantly worse than both Corsair RMx and MSI A-GF while being more expensive. Why??? This is an FSP built ACRF unit. Poor efficiency, atrocious transient response, noisy. Literally worse than the EVGA G2 and G3. Modern high end PSUs should be better than this. Both the RMx and A-GF (both CWT built) are LLC Resonant and perform much better than this, while having excellent build quality. Just what was EVGA and FSP thinking? Oh, also worse than Superflower Leadex III Gold, EVGA G6, EVGA G+, and EVGA GT.
