bit-tech published a review of the Enermax Infiniti 650W power supply
Enermax ticks me off with its poor maths and occasionally iffy modular plugs and to be honest I expected a little better from this unit. You may never use the 3.3V and 5V much at all in a modern PCβnot near the levels that weβve tested at and the 12Vs work perfectly fineβbut if a product claims it can do something, it should be able to stand by that claim. In this case, Enermax unfortunately hasnβt stood by that claim.Enermax Infiniti 650W power supply Review
The unit looks fantastic and still supports all sorts of PC setups, however, the extra cost and tough market might easily give enough ammunition for all the Corsair HX-series fans out there to play it down.
