Up for review at MadShrimps are a pair of fairly high powered PSUs, the CoolerMaster Silent Pro Gold 700W and the Corsair Professional Series Gold AX750, both around $150.  Both PSUs provide similar power levels and both are rated for 80+ Gold, on the advertising and in testing as well.  It is up to the available features to differentiate the two PSUs, with the Corsair product sporting longer modular cables and more of them as well.
