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.
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.
Another quality AX review and product from Corsair 🙂
Quality stuff, man I love Corsair. I have all their products, just wish i Could get a KitGuru case review
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.
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
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.
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.
@ 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.
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.
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.
John, take a deep inhale and calm down. There are no corsair ads here, so it seems pretty stupid to say that.
Seems like another great product from corsair. Not sure its worth it over the 850 which I think ill still get.
great site, glad I found it today.
Thanks for review, will use it to work out which PSU to buy next month 🙂
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 🙂
