Hi guys, just wanted to buy the CoolerMaster GX 550w to replace my old PSU which shows signs of aging already. Definitely would buy this because its the cheapest around and also did thorough research about this psu and found out that the older model receives mostly negative feedbacks. The RS-550-ACAA-D3 however receives oppositely, luckily the shop offers the same model, so my question is, is this a go or no go?
