Page 6 - Scoring

Performance (40% of the final score) - The Corsair AX750 did pretty well on the performance side of the scale. Voltage regulation was good, although there is a little room for improvement. On the efficiency side of things, the AX750 handed in excellent results easily meeting its rated 80+ Gold standard. The AX750 handled the heat very well considering my SunMoon combined with the ambient temps, wanted to push the unit past its 50°C rating. Other than our odd results in the second crossload test on the +5VSB ripple suppression on this unit was excellent. I'm going to have to go wit ha 9.0 here.

Functionality (20% of the final score) - I rarely find much to complain about on a fully modular PSU. However, I am a bit picky when it comes to the cabling and I've always been a stickler for a uniform look. The fact that the AX750 has some of the cables sleeved, and the others done up in the flat style just bugs me. I feel it would have been much easier to simply make the decision on one or the other. The cable lengths, connector options, and everything else is spot on here, I just can't get over the mixed styles on the cables. I'm going with a 9.5 here.

Value (25% of the final score) - You can currently find the AX750 going for 159.99 at Buy.com or Directron. This is just a few cents less than what OklahomaWolf just listed last week in his X760 review, which is what the AX750 is based off of. The slightly older X750 is going for a few bucks less, which means it's still going to be offering up some competition. This leaves us with the AX750 being a decent value, which means I'm going to have to follow OklahomaWolf's lead here and go with a 8.5.

Build Quality (15% of the final score) - Seasonic has been upping their game in this area here lately. Although their soldering has improved from the previous version, there is still some room for improvement. Where the Seasonic based AX750 shines is in the component selection, these units seem to have the right parts in the right places. I'm going to go with a 9.5 here as well.

Summary

  The Corsair AX750 shows that it is capable of producing the performance users want at a moderate price point. Although we did note that we seen out of spec ripple on the +5VSB in our second crossload test, one must remember that it's very unlikely to see that heavy of a crossload situation in the real world. How could you really go wrong with a unit such as the AX750? It puts out the power offering the user 80 Plus Gold efficiency even though I took the unit almost 10° past its 50°C rating. 

The Good:

  • 80 Plus Gold efficiency.
  • Quiet operation, even when at full load.
  • Fully modular cabling.
  • Good voltage regulation
  • Great ripple suppression excluding the +5VSB oddity we seen in CL2.

The Bad:

  • Nothing that concerns us here.

The Mediocre:

  • Decent value, but still has some competition.
  • Mixed bag of tricks with the cables.
