Performance (40% of the final score) – units that perform this well are really easy to score. In order to find something to deduct points for, we’ll look at efficiency, ripple suppression, and voltage regulation. Starting with efficiency, we had a clean pass for Platinum both times. No deduction there. We had excellent ripple suppression on all three main rails, so no points come off there. Finally, with an average regulation of 0.9% in the hot box, we have no deduction to make there either. This here 10 should come as a surprise to no-one.

Functionality (20% of the final score) – I’m still on the fence about ribbon cabling when used on the main ATX cable, but in this unit, the wires aren’t so stiff and bulky that they present a major problem. And fully modular is always good. I like the Corsair Link functionality, limited as it may be compared to an AXi unit. I like the fan test switch. Love the number of extra goodies that come with the unit, as well as the cable lengths and documentation. I don’t think I have any major complaints here. 10.

Value (20% of the final score) – $169.99 is the going rate at NewEgg right now. For ten dollars more, you can get a Thermaltake DPS 750W, which is Gold level efficient. For twenty more, you can get the AX760i. For the same money, there’s a Seasonic. But even so… you’re still talking about an awful lot of money just for the pleasure of getting Platinum efficiency. Corsair Link support does add some to the value, yes. But does that and Platinum efficiency really add up to a 750 watt unit with good value when Gold can be had for a fair bit cheaper? I don’t know. I’m thinking almost but not quite. I’ll do 8 here.

Build Quality (20% of the final score) – the old HX series used to be the best Corsair had before the AX and AXi units came along. As such, they were expected to be top notch in build quality. While the soldering on the mainboard of this unit was excellent, the modular connector board almost makes me want to score against it. Almost. In fact, CWT has upped their game in this unit enough that I think I’m ok with another 10 this time out. Barely. Let’s hope that other unit on the shelf looks as good to me.

The HX750i takes the old HX750, brings efficiency up to Platinum level, and adds a decent amount of Corsair Link functionality to the equation. While the price is disturbingly close to Corsair’s own AX760i and is higher than the vanilla AX760, it’s still a very solid unit with a good future in the marketplace. I want to see the price come down, but that’s more a side effect of the Platinum efficiency than anything else. Yes, Platinum can be had cheaper, but not much cheaper. And certainly not with the same level of functionality you get right here.


  • excellent voltage regulation on all three main rails
  • excellent ripple suppression on all three main rails
  • fully modular
  • Corsair Link enabled
  • 7-year warranty

The BAD:

  • Platinum is really expensive at the 750W level… from any company


  • I’m too sexy for this category
