Pros: FULLY Modular, Gold certified

Cons: None for the time being

This fully modular AX750, is brilliant.
It has enough power and is also very efficient (based on other reviewers).

I've had no problems with it, despite HW monitor displaying the wrong volts being produced (12v rail was showing up as 7v)

There's not much more to say of this PSU, apart from the fact that it powers my GTX 660ti PE OC, with no problems, and the fact that the modular design is GREAT for keeping your case and build super tidy.


Here's my unboxing of it:

Pros: Modular design, high efficiency, silent operation, sleek look, "sleeved" look on the cables

Cons: Pricey for the wattage

This was my first high end PSU purchase for my rig and I am very pleased with hit. Its being used with 2x GTS 450's and an overclocked i7 950. With that set-up, the PSU has more than enough power to comfortably power everything. In fact, this would only start chocking if 2x 570's were thrown into the mix.

The biggest appeal to me was its modular design. The cables are nicely labelled and because of the standard connector on the PSU, it doesn't matter which extension you plug into each port, with the excpetion of the 24-pin power cable. The PSU does have a fan, but it is dead silent. It is completely inaudible compared to the fans on my HAF 932.

The sleeved look of the cables really adds to overall aesthetics of this PSU, but it isn't perfect. It doesn't look as good as individually sleeved cables, but it goes pretty darn close. The caveat in my case was the stiffness of the 24-pin power cable. It was pretty stiff compared to all the other cables and even compared to other power supplies. This has become a little less pronounced after a couple months of use, but it is still quite stiff nonetheless. However, this could just be an isolated incidence in my case since I've never heard of any other complaints.

The efficiency of this PSU does bring up the price, but that's the price to pay. I was looking for the highest possible efficiency from a reputable brand, and Corsair did just that. Furthermore, the internal components used are actually capable of sustaining over 750W without damaging itself or the components. However, this goes without saying that its not something that should be done on a regular basis.

I really reccomend this power supply to anyone. The only down side for me is that this is now the limiting factor for high end dual GPU set-ups. For dual GTX 570's, at-least 850W is preferrable, but that is my mistake.
