I am running this PSU with an ASRock Extreme 3 mobo, AMD FX-8350 CPU, ASUS Radeon HD7870 GPU, and dual monitors. Not a hitch in it yet, everything runs top notch.

Great quality for price
good size
easy to handle
Not modular
Great PSU for price, it's a good size, not to big. And it provides a huge amount of power for gaming rigs at a reasonable price, works perfectly with my rig and i would buy again.

Price, 80plus bronze
Not Modular wire
For $60 this was a very good buy. Easy to use and no problem, was able to handle my OC 2600K, 2 HDD, 1 SSD and a GTX 570. Lots of connection such as SATA and PCI. At this price you can't go wrong.

Experience: 2 Weeks

Reasonably priced for such a nice power supply. Runs very quietly.
None so far
Got this for $59.99 after $20 rebate. My old power supply was not enough to run my new video card MSI GeForce GTX 660 Ti. 750W is well above the 500W minimum recommended with the 660Ti.

Experience: 3 Days

Works as described
I would buy another ;)
Quiet and cool is always good

Cables are nicely sleeved and are easy to manage.

5 years warranty

Got this on sale for 70 dollars. Awesome power supply with no problems running GTX 570 SLI configuration. . The 5 years warranty makes this an even better deal!

Experience: 3 Years
Great Price. Excellent Price when on sale!!
Bought the v2.2 of this Power Supply 3 years ago for a Overclocked Quad and Crossfire setup. Still works Great. Cost me 150$ for open box so great price for the new version. Would buy again for sure. Great tough product, AWESOME when on sale.

Power Efficient
Got one of these on sale for $50. This is a great PSU and has handled everything I've thrown at it. No crashes caused by PSU and is stable enough to have not killed a triple core CPU with an unlocked 4th core that was overclocked to 3.4ghz g 1.545v on air cooling. Easily handles two power hungry overclocked GTS 250s.

Experience: 1 Days

Built quality, price.
The power cable cannot be removed if not used.
This is a really great power supply considering it's quality and it's power (750W). When I built computer I always told my customers that the power supply is the most important part of the computer. This is a great power supply and the price is much lower than other similar psu.

Experience: 2 Weeks

Comment: GX is the new mainstream power supply series from Cooler Master that is arriving on the market today, so far featuring 550 W, 650 W and 750 W models. Let’s see if the 750 W model is a good buy.
Posted by: Will_H @03/15/11
Comment: Past Coolermaster units have done pretty well here in the lab, and I'm puzzled that this one has done so poorly.
Posted by: Lord Babaghan @06/12/10
Comment: A great value for an 80PLUS PSU declares this review.
