Performance (40% of the final score) – we’ll start off the scoring page with efficiency. This unit had no trouble meeting Gold parameters at every turn, so it will get no points deducted for that. Platinum would have been nice, but unfortunately only the larger 1kW unit has managed it so far. Voltage regulation was beyond excellent, coming in at an average of 0.7% in the hot box. Finally, ripple performance was mind blowing, with all rails barely touching the 10mV mark at worst. All this adds up to a 10.

Functionality (20% of the final score) – like the larger unit, I can’t think of anything to penalize Corsair for. The manual is excellent. The unit is fully modular. The fan controller works really well. There are no Berg connectors where I don’t want them. Lots of accessories. I could go on and on, but I’m tired and I think I have carpal tunnel in my right wrist. 10.

Value (20% of the final score) – $129.99 will get you one of these at NewEgg at present. It’s ten dollars more than the latest version of the RM750, which is based on nearly the same platform without the in cable capacitors helping its performance. But the real competition comes from Thermaltake’s Toughpower Grand at $119.99 and EVGA’s G2 at $124.99. Really, I would say that only the EVGA is an actual threat, and at only five dollars cheaper it’s not that much of a threat. Even so, I think I’ll go with 9.5 here.

Build Quality (20% of the final score) – the only thing to score on here is that awful soldering work on the VRM board. Half a point for that, and we’ll call it a day. 9.5.

SUMMARY

Corsair’s RMx line is clearly intended to make people sit up and realize they can still “bring it” when “it” needs to be “brought.” The RM750x isn’t quite the slam dunk box of pure awesome that the 1kW model was, but it certainly is no slouch at all in the performance department. The competition had best not get too complacent… Corsair is clearly still up to the job of being competitive in the marketplace.

The GOOD:

  • outstanding voltage regulation
  • amazing ripple suppression
  • fully modular
  • lots of included goodies
  • nice warranty

The BAD:

  • CWT’s infamous solder bug strikes again… this time confined only to the VRM board, thankfully

The MEDIOCRE:

  • what’s the deal with that nasty film on the PWM board?
