The AX750 is the third Corsair AX power supply we have reviewed and it has reaffirmed our opinion that the Professional Series Gold power supplies are the finest on the market, bar none.

The 750 model is finished to the same exacting standards as the AX850 and AX1200 and we love the understated design and simple aesthetic appeal. This PSU will look great in any system, regardless of lighting or internal structure.

Inside, the components used in the product composition are as good as you will find … independent DC output boards, double sided PCB and zero voltage switching to help raise efficiency and improve overall thermal performance. These claims are not just PR fluff as our testing shows how good the thermal performance and efficiency are – the unit manages to maintain over 90% efficiency throughout the full range which is not an easy goal to achieve.

In regards to acoustics the unit is fantastic with a hybrid fan design which means under very low load it switches off, therefore emiting no noise at all. This would make an ideal power supply for a high quality media center, with the user safe in the knowledge that this will not only handle potential upgrades, but it comes with a full 7 year warranty.

In the real world we tested this PSU with an Intel Core i7 970 at 4.5ghz with two 5870s in Crossfire X and experienced a fully stable system, even when running Furmark under dual GPU mode with Prime 95 in the background.

Pricing in the UK is reasonably competitive as it is selling for £135 inc vat, however the biggest competition actually comes from the AX850 which is only £15 more. If the difference was £30 or more then the AX750 would be a more viable option, but the AX850 seems better value to us at the current pricing. All being said however the AX750 is the finest 750watt PSU we have reviewed to date.

KitGuru says: Another extremely high quality product from Corsair which is helping to ensure the AX name is a class leader.
