Corsair AX750 Power Supply

From the Reviewer

Corsair AX line of power supplies has always been a great performing unit. The AX750 is no exception providing stable power delivery even when under extreme load when overclocking and gaming.


The Corsair AX750 ATX/EPS Modular 80 PLUS Gold is one of the higher-end professional PSU’s that Corsair produces, and we have an unboxing and review of it for you!

The PSU specs are very impressive, featuring 750 watts of combined power and a fully modular design. This model is aimed towards professional use, as evidenced by the fact that Corsair has that nomenclature attached to the AX line, as well as the color scheme. The color scheme of the PSU is gold and black, a scheme that I personally find pleasing but others may not like as much. The detailed specs of the AX 750 are in the photo below, but some highlights of them are the fact that the PSU has one powerful rail, as opposed to multiple less powerful ones, and the great fan profile when under load.


Unboxing and Impressions

The box I got is quite plain, but that is to be expected of a Manufacturer-supplied case. No fancy outer box, just the model name and specs, as you can see here:

After opening the box, you are at first greeted with a view of the accessory bag, extra Corsair bag, and the foam encasing the Corsair AX750. As you dig deeper into the packaging, you discover the incredible amounts of extra cables & accessories that Corsair has included in with the power supply. To be exact, you get:

  • 1x 24 pin Motherboard power cable
  • 2x 8-pin CPU cables
  • 4x 6+2 pin PCIE cables (there are two cables, each having two PCI-E cords on them for a total of four PCI-E connections)
  • 2x Flat Sata power cables
  • 1x Sata/ Molex combo cable
  • 1x Molex cable
  • 2 Molex to 4-pin adapter cables
  • 6x black screws
  • 1x Power cable
  • 10x Zip ties (for cable management)

This is truly impressive to see so many power cables and included extras. Gone are the days where all you got when you got a PSU and you were lucky to get extra screws, let alone an accessory bag. This is great to see, and not only does Corsair include all the power cables you could ever possibly use – they also are nice enough to have zip ties, screws, and not one but two bags to hold the extra cords in!

On to the actual power supply. The unit is encased in a very good, heavy-duty foam protective casing. On top of this, the AX750 is also covered in protective plastic to ensure against scratches that may occur.

And finally, the Corsair AX750 in all its glory. The unit has a matte black finish, with gold and grey highlights for the AX750 logo and decals.

As per on Corsair products, Corsair branding is the typical white and black scheme.

Installation and performance!

The installation of the Corsair AX750 was by far the easiest PSU installation I have had the pleasure to have known. This is mainly dur to the fact that the AX750 is the first modular power supply that I have ever used. That being said, the implementation of the modularity in the PSU is quite well done- no strange ways you have to plug in certain cables, all you have to do is see if the cable fits into the correct place in the back of the unit, and you are good to go! No worries about wrong kinds of power, or anything else. Installation of the unit was like any other PSU, put it in the case and then put the screws in to hold in the PSU. After that, attaching all the cables worked very well. I found it immensely satisfying to hear the audible clicks as each cord clicked into place firmly. Many other PSU’s do not have nearly as well built cords, and to be able to tell when the power cords are secure is a huge bonus to this Corsair PSU.

My rather jam-packed rig with the new AX750 installed. As you can see, the modularity helps out a lot in cramped cases like mine.

And finally on to performance. The Corsair AX750 is one of the best performing PSU’s I have had yet, Coincidentally, it is also the first unit that I have had that has as many features that the AX 750 has, like zero fan speed under low load, 80 Plus Gold certification, and so on. I do not have a PSU tester, but one thing that is impressive about the AX750 is that it actually outperforms my old 1000 watt Alienware PSU by a large margin in overclocking. I am now able to push over 20% higher speeds with my i7 3970x than with my old PSU, due to the incredible stability and clean power of the AX750.


The Corsair AX750 is one stable, solid PSU for overclocking, has a high wattage, and is decently priced for a modular power supply. Despite being aimed at professionals, the AX750 is one epic PSU for gaming and overclocking.
