    • Great Power Supply.

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. 😍 ... show more

    • Highly recommend
Style: MAG A850GL PCIE5
The MSI 850W PSU delivers everything you'd expect from a high-quality power supply. It's quiet, efficient, and provides stable power even under heavy load. Installation was straightforward, and the fully modular design made cable management easy and clean. Build quality feels premium, and the unit runs cool with minimal fan noise—even during long gaming or rendering sessions. It also comes with all the necessary protections (OVP, OCP, SCP, etc.), which adds peace of mind. Plenty of wattage for high-end GPUs and future upgrades. If you're looking for a reliable and efficient PSU that won’t give you headaches, this is a great choice. ... show more

    • Solid PSU, but the 12VHPWR cable is stiff
Style: MAG A850GL PCIE5
I got this PSU kinda expecting solid quality already, and honestly it didn’t disappoint. The build feels strong, and being fully modular helps a lot when building, no cable mess everywhere. evven with a good fan for cooling, It’s also pretty compact, fit easily in my mid tower case, which isn’t always the case with 850W units. It’s been handling my heavy setup with no issues so far. One thing tho, the 12VHPWR cable is really stiff, not easy to bend at all, so I had to be careful not to stress the connector. Other than that, all good. ... show more

    • Good Product
Style: MAG A850GL PCIE5
Works exactly as advertised modular cables seem to be high quality and come with a cool bag that holds the extra cables you are not using currently but may in the future. Lastly it has been working quite well in my new build would recommend.

    • Easy to install; works great (so far)
Style: MAG A850GL PCIE5
This replaced a 650 Watt power supply that was failing that was only about 6 years old. This one has a 10-year warranty so should last longer. I like the fact that it's modular and the cables are flat not round. So it was a little bit better fishing them through the motherboard.
