The MSI MAG A850GL PCIE5 850W uses an upgraded Channel Well Technology GPX platform to meet the strict ATX v3.0 and PCIe 5.0 requirements. It might not achieve groundbreaking performance, but it is not too far from strong entries in this category, which cost more. The main problem I believe MSI should deal with soon is the increased noise output, even at light loads, because the fan speed profile starts the fan above 1000 RPM. With a higher quality fan, operation at lower speeds wouldn’t be a problem, so MSI should use a higher quality fan, even if this slightly affects the product’s price. Most users won’t mind paying a few dollars more to get a better fan with an optimized fan speed profile, leading to silent operation at light and moderate loads.
Another thing that left an impression on me is the 12V-2×6 socket on the PSU’s modular panel, which, in fact, is a 12VHPWR one. Moreover, although the provided 12VHPWR cable has a 600W marking, it is set at 450W. I don’t mind that so much since a 600W setting for an 850W PSU would be an overkill, but users should have the correct information. All in all, MSI does a decent job in the PSU field thanks to its good cooperation with CWT, one of the best and largest PSU OEMs.
If you want ARGB lighting and lower noise output, with 5 dollars more, you can grab the Thermaltake Toughpower GF3 A3 850W, which I will review shortly. Till I do, you can read the Toughpower GF A3 1050W review instead! The MSI MPG A850G PCIE 5 also looks interesting, but I haven’t tested it yet.

You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.
