Corsair AX750 Power Supply Review

The Corsair AX750 arrives in an identically designed box as the AX850 and AX1200 units, featuring a very serious looking close up of the modular ports.

Inside the box the PSU is heavily protected between two thick pieces of foam. The unit itself is wrapped inside a felt bag to offer additional protection against scuffing. Corsair supply a well written manual offering support and information.

Extras include a power lead, mounting screws and cable tidies to help enhance your system build. Corsair also supply a little badge to proudly display on your case.

There is a bag containing all the cables, which can also be used for storage purposes as well. The cables are of high quality, some of which are sleeved/braided.

Along the rear are all the ports for the modular cables, while these aren't colour coded it shouldn't cause confusion as it is pretty obvious how they should be connected. The 24 pin power feed is directed into two feeds which are shown furthest left, top row and bottom row. The PCIe feeds take up the remaining three slots at the bottom. Sata and Molex power is fed from the five 6-pin power connectors top right.

The unit looks identical to the AX850 we reviewed last month, simple, clean and following a design ethic to suit the ‘Professional' moniker. A large 120mm fan takes centerstage at the top of the supply and the rear is vented to allow for maximum heat removal. There is a power switch and connector here.

  1. Weird the way the pricing is so close in the UK to the 850W model. 15 seems almost nothing for a 100W extra model in such a high class category.

  2. Another quality AX review and product from Corsair 🙂

  3. Quality stuff, man I love Corsair. I have all their products, just wish i Could get a KitGuru case review

  4. Eh? I was expecting this to be around £120, not £135? whats the point of that ? 850W is 150, id rather spend the 15 quid and miss out on a few pints on a saturday afternoon.

  5. Zardon you are a total friggin Corsair fanboi. This should be deducted for the price. its far too close to the 850 unit. 7/10

  6. I agree, 9/10 is too high. needs to lose a point at least. they are pricing this against the 850W. Lets have a vote to make Z change his mind.

  7. You can’t give such a fantastic unit 7/10 cause its £15 over the odds. I am positive the price will drop when Corsair sort out the UK market, which is normally secondary to the USA.

  8. @ Tech Head – man seriously, catch a grip. What if it was priced at £200? still 9/10? If companies ilke Corsair have fan boys like Zardon kissing their ass with every review then the prices will never drop. 135 for a 750 PSU when the 850 is 10-15 more is stupid.

  9. Did you idiots ever think that the 750W is mostly the same internally and costs them very little less to produce? £15 isn’t a bad reduction. I agree it should be 10-15 more, but you can’t score a product low because the UK pricing is a bit off at the tminute.

  10. Is this the Zardon fan club in here? im not knocking the review, just the score. I see other sites with corsair ads all over them and all their products get top marks, its paid for reviews. This is the same.

  11. John, take a deep inhale and calm down. There are no corsair ads here, so it seems pretty stupid to say that.

  12. Seems like another great product from corsair. Not sure its worth it over the 850 which I think ill still get.

  13. great site, glad I found it today.

    Thanks for review, will use it to work out which PSU to buy next month 🙂

  14. I love corsair power supplies I still have my TX unit and I love it. I will get one of these AX units next year for my upgrade when new 6000 ATI cards arrive 🙂
