At 550W and an 80 Plus Bronze rating the Cooler Master G500M is not as powerful as many of the PSUs we have seen lately, then again at $75 it is also more affordable. Unfortunately for Cooler Master the competition tends to be lower priced, with Corsair, SeaSonic and Thermaltake all having slightly better PSUs of a similar wattage for an equal or lesser price. On the other hand Cooler Master's five year warranty is longer than any of the other brands and [H]ard|OCP feels that the G500M shows improvements over previous models as it passed all of their tests. This particular model may not be a great choice but if CM continues to improve the quality of their budget priced models the next release might be a solid contender.
"Today we spend our time with a computer power supply from Cooler Master that is towards the lower end of the wattage scale coming in at 550 watts. Cooler Master claims "notably higher efficiency and voltage stability than other designs." We will see if its Bronze efficiency G550M PSU will stand up to our gauntlet and its own claims."
