Conclusion And Recommendations
The current crop of 80 PLUS Gold-rated power supplies in the 700-900 W range demonstrates what modern power supplies can really do. Each unit we tested easily accomplished the demanding tasks we threw at them.
However, there were a few small (but meaningful) differentiators among the four devices. Seasonic's X-760 and FSP's Aurum AU-700 performed especially well. The latter boasts both the best test results and lowest price. If you simply cannot do without modular cable management system, that leaves Seasonic's unit.
Antec's HCP-850 is likewise free from glaring imperfections, save the lowest efficiency numbers at minimal load levels.
