Reliable PSU, fits wonderfully in my case, and I like that it comes with plenty of cables for you to work with. I never hear the fan, which is nice. Good PSU, I would recommend especially if on sale.

The MSI MAG A750GL PCIE5 is a strong choice for a modern desktop build. I like that it is fully modular, which makes cable management much easier, especially in smaller or cleaner builds. The 750W capacity is a good middle ground for many gaming, workstation, and general PC builds, and PCIe 5 support makes it more future-friendly than older power supplies. The unit feels like a good value for the feature set, especially with 80+ Gold efficiency and a 10-year warranty. As always, make sure 750W is enough for your specific CPU and GPU combination, but for a lot of systems this is a very reasonable choice. I was very satisfied with it.

I've been using this power supply with an MSI motherboard, AMD Ryzen 9 9950X3D CPU, and NVIDIA RTX 5090 GPU for over a year now. The power delivery has been rock-solid stable, and most importantly, the GPU power cables show no signs of overheating or connector issues—a critical concern with high-power graphics cards. The reliability has been exceptional throughout daily heavy gaming and workstation use. What really stands out is the value proposition—it's significantly more affordable than comparable 1250W units from competitors while delivering the same or better performance. I highly recommend this PSU.

I'm thrilled with the MSI MAG A750GL power supply! This PSU is a feat of engineering, delivering 850W of clean, reliable power with 80 Plus Gold certification for excellent efficiency and reduced energy consumption. Its fully modular design makes cable management effortless, resulting in a cleaner build and improved airflow. Support for PCIE 5.1 and ATX 3.1 also makes it a future-ready choice for any modern gaming setup. Its compact form factor is another advantage, allowing for easy installation even in tighter cases. Once again, MSI proves its dedication to quality and high performance. Highly recommended for any gaming enthusiast or PC builder!

It's the best power supply I could have bought, it works perfectly, and its energy consumption is excellent. I've been using it for about six months, and it's doing its job. I'm very happy with it.

This is an outstanding PSU for the money. It is extremely quiet and has plenty of modular cables included and even a bag to store the ones you don’t use. Comes with one PCIe5 cable, ATX connector, two CPU cables, two PCIe cables, an SATA cable, a molex cable and is ATX 3.0 ready. The ONLY reason I took off 1 star is that the 24pin ATX connector has to stretch oddly to fit into the PSU, you almost feel like your going to break the cable the way you have to twist it to fit into the PSU. The same connector is also tough to fit into the motherboard. It feels like it just doesn’t make a good connection or snap in. I’ve installed 3 of them, 2 connected to a ASUS motherboard and 1 used on a MSI motherboard, and it was the same feeling trying to make the connector fit. One of the computers wouldn’t turn on one day and I took the connector off the motherboard and plugged it back in. It still didn’t work, then I twisted the cable a little bit and the computer started up. I would buy another for $100.

I bought this to build a video server and the power supply works perfectly. It is quiet and has been reliable for over 6 months and I don't expect to have any future issues with it.

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.
