Amazing Power Supply

This hefty chonk of metal will absolutely suit your 850W PSU needs. It's very quiet under operation, cords are braided and quality feeling. Not to stiff, but not to loose either. Very secure connectors. All cables come in a very nice Velcro bag, so all those random extra SATA cables and such can be stored in a nice way. VERY HEAVY. Cant even lie, even the box is pretty nice too lol. You really can't complain, great power supply.

Excellent power supply for a modern gaming PC. The MSI MPG *********GS feels very well built, and the fully modular design made cable management much easier. The embossed jacket cables are a nice touch and give the build a cleaner, more premium appearance. I also like that it supports ATX 3.1 and PCIe 5.1 and includes the newer 12V-2x6 cable, which makes it a great fit for newer graphics cards such as the RTX ********* and ********* series. At ********* with an 80 Gold efficiency rating, it provides plenty of power without going overboard. Installation was straightforward, it runs quietly, and the 10-year warranty gives me a lot of confidence in the long-term reliability. Overall, this is a high-quality PSU with modern features, clean cable management, and plenty of power for a higher-end gaming build. I would definitely recommend it.
