Having to replace a one year old 750 watt switching, non-branded power supply unit (PSU) due to power fluctuations caused by a 2GB graphics card & new processor I must say that this is an outstanding piece of hardware.

Pros:
Very quiet. The fan on my graphics card makes more noise, even writing information to the hard drive is louder.

The unit is what's apparently termed 'modular', which means you only connect power leads to & from it which are actually required. This means no surplus leads hanging down, taking up space & restricting air-flow in the PC case.

Easy to install.

7 year guarantee.

Cons:

Either the unit's a few mm larger than the previous one, or perhaps the leads are positioned differently, but I had to reposition one of the cooling fans on the top of the case to accommodate it.

The cost. It's expensive, but a stable power supply ensures longevity of CPU, graphics card, & drives. That's why trying to cut costs on a cheaper PSU is a false economy.

Purchased this power supply to replace a failing OCZ 850W PSU in a 4/5 year old computer. Fits perfectly in the Coolermaster Cosmos S case with the fan facing down. Noise levels dropped dramatically and now I can actually hear the hard drives. The manual is pretty much useless but there is some useful information in corsair's website about the cables (search for Corsair AX 750 cables), that is the only info I needed. Powers a quad core Intel cpu, 8800gtx, 5 hard drives, 2 media drives, internal high end soundcard and an array of external devices with ease.
Highly recommend the AX series of PSUs based on this experience and it is a good base for future upgrades.

I love this product. The modular feature reduces the amount of wires in the case, and as it is Corsair, you know that it is a quality product, with an excellent warranty and industry leading returns and replacements.
The PSU is quiet and has never not provided the power my rather high-end pc requires.

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.

Received this as a gift; it would become the beating heart of an excellent system shortly thereafter.

The unboxing was exciting and the packaging is premium outside and in. Mesh bags hold the individual modular cables and Corsair haven't skimped on leads. The PSU itself is handsome and rugged with its industrial-looking guts visible from above.

As far as power output, it lives up to its Raison d'être with stoic silence. Running with an overclocked i5 3570k and Radeon HD 7950, I am certain I could add another video card in Crossfire mode, water cooling, many more drives, or whatever else I fancy and still have juice to spare.

It should be mentioned that this supply is very energy efficient and also is actually capable of pulling the full rated wattage, unlike cheaper devices. It is probably overkill unless running an enthusiast gaming PC or heavily loaded server. Consider something from the TX line if you don't need or want a modular design.
