Style: MAG A1000GL PCIE5
Upgraded to the MSI MAG A1000GL for my gaming build after my original died, and it's been excellent. Fully modular design made cable management a breeze, and the compact size fit perfectly in my mid-tower case. It’s ATX 3.1 and PCIe 5.1 ready, with a native 12VHPWR cable — perfect for powering modern GPUs without extra adapters. Runs quiet, stays cool, and delivers clean power under load. The 80 Plus Gold certification is a nice touch for efficiency, and the 10-year warranty gives me peace of mind. If you're looking for a future-ready, high-quality PSU, this one's a solid pick.

I'm delighted with the MSI MAG A750GL power supply! This PSU is a marvel of engineering, delivering 750W of power with 80 Plus Gold certification, ensuring exceptional efficiency and optimized energy consumption. Its fully modular design makes cable management a dream, resulting in a much cleaner PC interior and better air circulation. Additionally, the fact that it supports PCIE 5.1 and ATX 3.1 makes it a future-proof option for any modern gaming setup. Its compact size is a plus, making it easy to install even in cases with limited space. MSI has once again demonstrated its commitment to quality and performance. Highly recommended for any gaming enthusiast or PC builder!

Awesome PSU. I wanted to do an all white build and finding a affordable white psu was a challenge. This one not only hit the perfect budget range but comes with tons of features, cables, etc...to accommodate any build. Comes with a nice cable case for the extra cables.

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.

Great power supply and the modular feature is phenomenal, making assembly so easy. I’m a big MSI fan, so the brand was a no brainer. I’ve been running this for a few years and it run smooth and so quiet. If I need to replace the power supply, or build another unit, I’ll buy the updated PS for sure!

I like this PSU. It’s my first modular one and I found it very easy to build my system with it. My only gripe is that it doesn’t turn the fan off while not under load. I bought this rating for the purpose of saving money on the power bill and it seems silly that the fan is always on. That being said, it is not noisy. I would buy it again if I had the same budget since this was the mes one I could find for this price when it comes to efficiency and longevity. The cable length is great, my PSU gets connected without being tugged by it. A great quality item all in all. Definitely it’s worth its price.

I had to replace my older Corsair RM650x. I built a new gaming PC and used it. My old one was good for a little while, (almost a year). It started getting noisy and my system would black screen. I couldn't do anything, except power off the system. This power supply is an upgrade. My system is so quiet now and so far it's running smoothly. The power supply came with flat cables which is great. I don't have the bulky ones anymore so there is more room to work. All the connectors connected without problems, and was easy to install. My system config is Ryzen 9 9900X 12-Core 24 Thread, MSI MAG X870 TOMAHAWK WiFi Motherboard, NVIDIA GeForce ROG GTX 1070 graphics card.

Purchased this PSU as a first step effort to repair a freezing new PC build that was leaning on an older, excellent EVGA PSU that was well past its own 10 year warranty. While the EVGA PSU was ultimately not to blame, I did keep this MSI one on hand to keep vendor variety to a minimum on my MSI 870 Tomahawk build that was still giving me issues, and it was nice to have a power supply that natively had the 12VHPWR cabling available. I appreciate the modular design of this PSU, the only variety I tend to buy these days, and this one in particular has a much smaller footprint than the one it ended up replacing which affords more room during the cramped cabling stage. I do find it much more difficult to remove the cables from this PSU than I do others that I own, something that can be a bit of a pain when you're trying to remove just a single cable rather than the whole PSU to do so. While the warranty is amazing in length (10 years!), I can say from having to deal with MSI's warranty service for the motherboard, I'm not a huge fan of the process; primarily they're quite slow to turn things around, and will use the slowest shipping process available (not to mention shipping to them on your dime). There's also no Advanced RMA option (though that seems to be losing favor in general with companies). Contrast that with other vendors like AMD who sprung for overnight inbound shipping for me and used 2 day to send parts back and I'm hoping I don't need to lean on them for this PSU in the future. Overall though, I'm happy to have this more condensed unit in my new build and it shows no signs of trouble with my limited use case thus far.
