Review: Reliable Power Supply – Great Value for Money - The MSI MAG A550BN is a solid and reliable power supply. Installation was straightforward, and it provides stable power with no issues so far. It’s been running quietly, even under load, which is a big plus. The build quality feels good for the price, and the cables are decent quality and long enough for a standard mid-tower case. At 550W, it’s more than sufficient for a typical gaming or everyday PC build. Overall, this is a dependable and affordable power supply from a trusted brand. Ideal for budget or mid-range systems, and I’d happily recommend it.
Review: Great Psu!! - Fantastic PSU, arrived today (delayed by desertcart despite Paying for next day) very easy to Install despite missing Instruction lol thankfully its basically idiot proof anyway if you know what your doing. Super quiet, very fast to install absolute dream. Might need to step it up to a 750w once I've built my new PC in a couple of months depending on the power drain of the new GPU I buy for it and if I need to I will deffo be buying the 750w version too. Cables are all provided and easy to connect to both the PSU itself and the Motherboard. Packaged really well so no damage. Looks really nice, not that I can see it now its installed but still and very sturdy design. 80+ Gold Rated so should help keep the energy costs down and powers everything in my current build perfectly. What more can I say? Top piece of kit well worth the cost vs a cheaper PSU.
