730W-900W Power Supply Roundup

“Though the power supplies have different max outputs, they can be regarded as one group serving the high-end market. These are power supplies for people running more than one graphics card and multi-core CPUs, probably with some moderate overclocking as well. After looking at the test results, we like the Cooler Master M850 and Antec TruePower Quattro 850 the most. They are reliable and have very stable DC outputs. They also generate the highest efficiency scores of the group with up to 87% at a medium load of 400W (with 230VAC). However, the ripple results could be better, and from in terms of noise the Cooler Master performs better than the Antec unit.”
