Reviews
550W Cooler Master G550M, 80 PLUS Bronze, Hybrid Modular, SLI/CrossFire, Single Rail, 42A +12V, 1x120mm Fan, ATX PSU is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Quality cost effective PSU I originally bought this PSU as a test unit to so I had a spare to check for possible PSU fault on my gaming rig. Also for use in a HTPC I intend to put together when I get around to it. Turned out it was a faulty PSU with my main gaming rig, so While it was only going to be used as test. It ended up being used for a few weeks supplying the power to my overclocked 4770K and R9 290X with no problems. Even though it was running up near it's 550w limit, it never failed or ran too hot. The cables supplied are basic plastic, but no different to the cables supplied with more expensive Corsair PSU's. The price/performance of this PSU is excellent and I would recommend it to anyone who was building a PC on a budget.

Rated 5 out of 5 by from A solid PSU If you are looking for a cost effective solution for a tidy build that provides perfectly stable voltages look no further. This PSU is handling a 280x toxic and athlon 860k without issue. All the voltages stay stable and there is only cool air coming out of the exhaust showing that it isn't even straining under load.

Rated 5 out of 5 by from good value and does the job I use it in a media system where heat/airflow is a issue due to having a fx cpu and a gtx 670 combo. I now have less redundant cables coming of the PSU that has reduced the temps inside the unit by 2c. And due to the slim nature of the modular connectors it looks cool too. When weighing up which psu to I compare this and the Corsair CS550M and chose this one because the cable management and price. Yes it is only a bronze rated supply unlike the corsair but when you weight this up alone with the price difference I am more then happy with it and believe it to be the best 550w PSU for the job.

Questions & Answers

Will this run a GTX 760 ok?

got a GTX 760 in my machine that i bought recently and my current PSU is able to run it on desktop and lower end games but if i try running something higher it just resets my pc, after confirming i need a PSU upgrade i came across this one in my price range and want to know if it will handle it well
Asked by: Trystau
Without knowing what CPU and other components you are running I can't give a definitive answer, what I can say is. I had one of these running an intel [email protected]/AMD R9 290X while gaming on ultra settings on BF4. The Nvidia GTX760 is rated for around 170w peak power draw, while the AMD R9 290X I have pulls around 300W peak. So I can't see any reason why this PSU shouldn't be able to power your PC.

why is this psu in non modular

shouldnt it be semi modular ?
Asked by: Graeme70
Motherboard 20+4pin, motherboard 2x4 pin and the two pcie 6+2 are fixed all the others are modular. So yes I would regard to as semi modular but I think to be regarded as that the pci cables also have to be detachable as well. Otherwise the nerds out there get there nickers in a twist and ask for a refund of coolermaster.
