Plenty of Power with Reasonable Price
Style: MAG A850GL PCIE5
Great power supply with plenty of ports and even comes with a 12V 2x6 port for your GPU and cable. The power supply is quiet and stable. Well packed and delivered on time.

Works like a charm
Style: MAG A850GL PCIE5
If you are building a modern mid-to-high-tier gaming PC (like a Ryzen 7 + RTX 4080 / 5070 Ti or RX 9070 XT combo) and want a solid, hassle-free power supply that won't fight you during installation, this is an absolute workhorse. It isn't a ultra-premium halo product, but it nails all the stuff that actually matters day-to-day ... show more

Great Product for the right price.
Style: MAG A850GL PCIE5
Super easy to install in my 2024 MSI Aegis. I upgraded from the RTX4070 in this machine to an RTX5070 TI OC. The 750Watt PSU that came with could do it, but would freeze up on max settings. Now, that stopped as there is enough power to draw from. Cables are easy to install, the fan is quiet, and the PSU cable being yellow makes it easy to locate. Great product and comes with a cable pouch too! ... show more

Well built PSU, great price, but i suffered loud coil whine with the 9800x3d + 5070 ti.
Style: MAG A850GL PCIE5
This PSU worked great with my 12700k and 5070 ti. But once I upgraded to the 9800x3d, this thing was buzzing like crazy. The coil whine went off the charts after upgrading my CPU. It seriously was the only fault I had for it. It had plenty of wires included and all the necessary hookups. Its great for the price because its very well built. Cant fault MSI for coil whine on such a great priced PSU. But I ended up replacing it with the MPG a1250gs and its been night and day with coil whine. I dont have any issues with the MPG with coil whine or any noise, seriously quiet as a mouse and buit so well. I honestly have to say I do prefer the braided wires that are included with the MAG 850 over the MPG 1250. ... show more

Great. Quiet. Cool.
Style: MAG A850GL PCIE5
I ordered this power supply when I upgraded my cpu and needed more power. The modular cables made it very easy to install. It works perfectly so far, and runs cool. It doesn't have that strong, acrid, PC electronics smell that some pc components have when unboxed. The 24 pin motherboard connector is at the left side of the front face of this PSU. When installed in my case (and likely many other cases), this puts the motherboard connector at the front of the case. It would be easier if the motherboard connector were at the right side of the front face. This would allow for less visible wiring after installation. Overall though, it's great. ... show more

Good deal
Style: MAG A850GL PCIE5
UPDATE *Received a replacement unit (whole new box etc.) and the cables were longer and I've had no power issues so far.* Wires are too short. Too stiff. And my unit was defective, causing strange mouse lag when starting computer, which means, it's defective and could damage components. And I'm not surprised. The wires are thick and need to bent so much that the positioning at connector points physically stress the ports on the motherboard, essentially causing microscopic uneven sitting which can cause serious issues. They really need to work on the flexibility of these wirings. And make the cables longer. I will be switching to a 1000watt if I continue having issues. 5080, 9800x3d, 32g ram, m.2 ... show more

Very nice power supply...but oh the fan noise!
Style: MAG A850GL PCIE5
There's a lot of great things to like about this power supply, including the removable connectors, the many cable options, and the clearly labeled connections. Though I can't speak about longevity yet, I'd assume it will last quite a while. The problem is with the fan. I can't say for certain what the speed was at cold start, and there wasn't any rattling per-se, but the fan was just loud, like way too much air noise for just starting up. I took it apart to investigate, and saw there was a Martech 12V fan being powered by 5V. So this is the lowest voltage setting for this fan, and with heat this will only get faster/louder. For Ss and Gs I powered this stock fan with an external power supply and varied it from 5V to 12V and it did indeed get faster and louder....very loud....like a drone flying around. If this was in your computer, I can guarantee it would be the loudest thing in there...no thanks! An option could be to buy a quieter fan, but due to the voltage speed control in this PSU, there's no way to know (or control for that matter) the speed or temperature. So I bought a standard Noctua 12V fan to replace the stock fan, and wired it to the motherboard. This way, both the temperature and speed can be controlled. Now it's working great, it's much quieter, and I can boost the fan only when the system needs it. ... show more
