While several tech websites gave Cooler Master GX 750W favorable reviews and have recommended it to potential buyers, but one website did not. According to this article at Hardware Secrets, the GX 750W has a MAJOR flaw: high electrical noise and ripples at 80% (600W) and 100% load (750W).

Only Hardware Secrets tested PSU in terms of electrical noise in addition to Voltage Regulation. While voltages are stable at high load, noise level was said to be above the 50mV limit which could overload and harm other PC components. Hardware Secrets recommended 450W as the safe limit. :(

My PC system specs are as follows:
CPU: Intel Core i7 2600 3.4GHz (cooled by Cooler Master Hyper TX3)
Memory: 2 X Kingston 4GB DDR3 1333MHz
Motherboard: ECS H67H2-M
Graphics: Powercolor Radeon HD6870 2GB GDDR5 Eyefinity 6
SSD: Patriot Memory Pyro 60GB SATA3
HDD: Western Digital 640GB Caviar Blue SATA2
Optical Drive: LG 22X DVD Rewriter SATA
PSU: Cooler Master GX 750W

Generally, how much is the load in % during heavy gaming (e.g. playing Crysis 2 at max. settings for hours)? Is my PC in danger of getting fried due to overload from the Cooler Master PSU? :~

No danger with the hardware you have, but upgrading later might be problematic. I would probably update the PSU anyway, at some point, just to be on the safe side.

This is by far the best place for PSU reviews. I trust no other source.

As for a PSU recommendation, I would I would go with this unit instead. Its a tested model that has sold thousands of units. Jonny gave it an 8.3, which on his scale is decent. For the money, its going to be one of the better PSU's until you start breaking the $150 mark.

Thanks for the link. I've bookmarked it (also Hardware Secrets) and I'll make sure to read the reviews first at these site even before considering buying a new PSU. Prior to my discovery at Hardware Secrets, I only took account the brand name and wattage values.

I just realized something. The GX 750W featured in all the reviews doesn't have the "Bronze" label both on the unit and the packaging. The review units are 80+ certified but mine is 80+ Bronze.

I may have based my fears on outdated info. :doh
