Cooler Master GX 550W

Hi all.. im currently using this Cooler Master GX 550W Bronze 80 Plus PSU with my current rig.. I don't know but for some reason people here saying that this PSU sucks and is known for damaging hardware. So tell me should I buy a new one that is better than this? or does anyone have any Good/Bad experiences with GX Series PSU's Please Help!

Reason i'm asking is im worried. I just recently build a new rig and I don't want to fry any of the components due to the malfunctioning of the PSU! Also I heard a strange kind of noise that came only once from the Rig side.. it wasn't a beep but it sounded like thin and sharp noise like pooooooiiiiinnnngg.. don't know if it came from the board or the psu or any other thing... but PC kept running fine.

That is a decent psu, but is on the lower end of their models. Looking at your specs you have a good build. I would get a better psu, and keep it as a back up for testing. Corsair and Seasonic are good choices, others will add more. The psu is one component you do not want to cut corners on. I would go for a modular one.

If you aren't afraid to spend a little money on a PSU that you can use for this build and probably the next build, I'd go with this one: SeaSonic X Series X650 Gold

Fully modular, Haswell ready, all black cables, and made by one of the best PSU manufacturers around.

ok thanks kbrady and dude... but in Pakistan there are only ASUS, Corsair, Cooler Master, FSB, Thermaltake and Xigmatek available easily so which particular model should I go for? in 500 to 600 Watts as i'll be adding GTX 760 in couple of months in the Rig!
