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 PC—not near the levels that we’ve tested at and the 12Vs work perfectly fine—but if a product claims it can do something, it should be able to stand by that claim. In this case, Enermax unfortunately hasn’t stood by that claim.

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.
