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.

So far so good! A fully modular PSU with decent cables that fit last gen cards and mobos, plus the packaging inside the box is impressive. All the cables come secured in a enclosed velcro pouch, and the PSU is is protected with high quality foam so it wont get damaged in shipping. The unit is also very light. All my previous PSU (EVGA 850W and 550w) are HEAVY, but this one is super light. I've always been impressed with MSI mobos so its no surprise this PSU is top tier. No whining of any kind, great packaging, descriptive, and its light. 5 stars.

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.

Power supply supporting my build very well. The fan is a little noisy, but I haven't bought a single power supply of any manufacturer that doesn't have the same issue. As soon as it's out of warranty, I'll replace the fan just like I've done with all the others.

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. 3 Months Later: Fan already seems to be failing a bit; PSU still works fine, but the thing is easily the loudest component in my PC while idling...in a case where there are at least 10 other fans to compete with. A bit disappointed with it, though probably not worth a warranty replacement yet, assuming MSI would humor one at all for mere fan noise. Worth shaving a star off; this one pales in comparison to the now ancient EVGA PSU it replaced.
