Performance (40% of the final score) – time for the scoring. This unit performed really rather well for a bargain unit, did it not? Where the first version shut down once the heat came into play, this one did not. As a result, it was able to pull down excellent voltage stability numbers, averaging 1.33% in the hot box. It’s not mythic level, but we’ll definitely take it. Even so, I do have to deduct a half point for not being past the 0.5% mark. No more points need removing, though… ripple control was excellent at 18mV at worst, and this unit passed all efficiency requirements. 9.5.

Functionality (20% of the final score) – this is not a high-end unit, and this is one area where it shows. Not compromising on performance means the cost savings have to come from somewhere. In this case, I don’t think they went too far with it at all. The unit is only semi-modular, which is a half point deduction. There are Berg connectors where I hate them, so that’s another half point gone. But I don’t really see any more issues to score on, do you? 9.

Value (20% of the final score) – $89.99 is Newegg’s price on this unit right now, but it’s a bit tricky. Currently, there’s really no way to tell if you’re getting the old or new version with them. Indeed, the model numbers are exactly the same, so you pretty much need to be looking at the unit before you can tell for sure. The pictures on their site are of the old version, though the 650W version does seem to have been updated there. Now… one of the biggest issues the original version had was poor value against some of the competition. Sadly, I don’t think this has changed very much. EVGA has the B1 and B2 for a good bit cheaper. Seasonic has a Gold model cheaper. Rosewill has two models in Gold either at the same price or five bucks cheaper. But that’s just Newegg… Fry’s has the CX750M listed at twenty whole dollars less, which makes it far more competitive. Again, though, it’s hard to say which version we’re talking about. I think I’ll drop a 7 here.

Build Quality (20% of the final score) – one point comes off for the fan, half a point for the soldering. Everything else looks fine to me. I’ll let the caps go – the ones that matter are all Japanese or polymers. 8.5.

The new and improved version of the Corsair CX750M is just that in many ways. Performance is improved thanks to being able to handle reasonable temperatures, and we do have a new box and new stickers on the side of the unit to help us tell which is which. It is also improved in build quality from what we saw in the old model. However, the price remains a big question mark. Newegg’s price is, quite frankly, nuts. No way is anyone buying one of these when a Seasonic G-750 is the same price. Fry’s is much better, but which version are we getting? Last time, I remember recommending passing on this unit and going with the CS-M series instead. And that range is still superior to this one, I think. But if you can get this unit around Fry’s price, I don’t see any reason why you shouldn’t. It has all the ingredients needed to give you stable, reliable power for one heck of a long time.


  • improved build quality from version one
  • excellent voltage stability
  • excellent ripple control
  • semi-modular

The BAD:

  • hard to tell apart from the old version on store listings – you almost need to be looking at the retail box in person


  • CWT needs another wake-up call on their soldering before they slide back into mediocrity
