This review is about a 550W PSU from Cooler Master, according to the reviewer it's a solid performer that doesn't disappoint in any area.

"Power supplies are often almost overlooked when building a new PC and with many newbie’s to the field there are many people without a clue as to which wattage suits them and their requirements best. Thankfully though CoolerMaster have come up with the GX series of power supplies which are a line up of high performance, high efficiency PSU’s aimed at the mid to high end of the gaming systems market. Today we have one product from this line. The GX550. Let’s take it for a spin."
