Style: MAG A850GL PCIE5
I built an all MSI PC and couldn’t be happier. I have a X670E motherboard, 7700X CPU, 7900XT GPU in an MSI 111 case and this power supply has been wonderful. I have pushed my GPU and CPU to the max with power and this has had zero issue powering my tunes. Cable management was easy, it’s quiet and has been great. The fact that my case can also show off the power supply makes me happy as I love MSI’s dragon 🐉 and I gotta lot of them to show off. It comes with all the connectors you would need no matter the build and has been a great power supply. MSI is awesome and I love them. 😍

The MSI MAG A1250GL is an absolute beast of a power supply. With 1250W of 80 PLUS Gold certified power, it easily handles high-end gaming rigs and workstation builds without breaking a sweat. The fully modular design keeps cable management clean and simple, and the build quality feels premium throughout. What really impressed me was how quiet it runs—even under heavy loads, the fan stays whisper-quiet thanks to the smart fan control. The inclusion of ATX 3.0 and PCIe 5.0 support makes it future-proof, especially for powering GPUs like the RTX 4090. If you're looking for a high-wattage, reliable PSU that delivers stable power and top-tier efficiency, this is it. MSI nailed it with the MAG A1250GL!

Product works great with plenty of cables and options for plugging in all the pieces for my new gaming rig. Not super bothered by noise since I'm usually gaming with headphones, but this runs cool and quiet. Feels sturdily built and has enough power to allow for future upgrades. Super happy with this buy!

Super simple, easy to use to and install. Theodukar cables made cable management a breeze. I have plenty of wattage capacity to run my 9800X3D + RX 9070 XT Nitro combo. It's easy to install, coming with the screws needed. I really appreciated that all the modular cables come in their own felt bag nicely organized and bundled. It was a nice touch. Good PSU, nothing to complain about and all smiles and thumbs here.
