Efficient and high quality
It works perfectly and is great value for money, I love it

Quiet power and meets my needs exactly
I replaced a 430 watt supply with this one. It might be overkill but it's working fine and temps all look good. I was concerned about the fan barely moving air but don't panic! It has semi-passive/zero RPM mode when it is operating in low load / temp. 650 watts are not struggling in my system at all. I'm not running a cutting edge gamer box and your needs might be greater.

Works perfectly
I've had 0 problems with it and it was super cheap. Makes almost no noise. The cables are a bit stiff

Works in old prebuilts.
Fixed a friends old dell computer. Swapped out a eight year old power supply with this thing in about a hour and the computer works perfectly. MSI makes good power supplies as it "feels" durable.

Solid Budget PSU for a Homelab or Server Build
I’m using the MSI MAG A650BN 650W (80+ Bronze) power supply in a small homelab server, and it’s been reliable with no issues. The system runs 32GB of DDR4 RAM, an AMD Ryzen 5 CPU, and an underclocked RTX 3060 Ti, and the PSU handles the load without any instability. Even though it’s non-modular, cable management was manageable, and the unit runs quietly, which is important for a server that stays on for long periods. Power delivery has been consistent, and I haven’t experienced any random shutdowns or power-related problems. For a budget-friendly power supply, the build quality feels solid and dependable. If you’re putting together a homelab, NAS, or server that doesn’t need premium features but still requires stable power, this has been a great choice. My only complaints come down to it not being modular, but as long as you know that going in you should be fine.

Well constructed and look good too.
Looks to be well constructed like all the rest of their products. The video cards, main board and now power supply. Very good choice for today's power hungry devices. Looks good too.

Reliable and Efficient - MSI MAG A650BN Delivers
I recently upgraded my gaming setup with the MSI MAG A650BN Power Supply, and it's been an excellent decision. This 650W PSU is 80 Plus Bronze certified, which was a major selling point for me. It means the unit is not only energy efficient but also reliable in power delivery, a crucial aspect for gaming rigs. The compact size of the MSI MAG A650BN is a big advantage. It fits easily into my gaming case, leaving ample room for airflow and other components. Despite its smaller size, it packs a punch in performance, handling my gaming load without any issues. The build quality is solid, giving me confidence in its durability and long-term performance. It runs quietly, even under load, which is a pleasant surprise and adds to a more immersive gaming experience. Another aspect I appreciate is the range of connectors and the length of the cables. They are sufficient for a clean and organized setup, allowing for easy cable management. Overall, the MSI MAG A650BN Gaming Power Supply is a top-notch choice for gamers or anyone building a PC who needs a reliable, efficient, and compact power supply. It offers great value for its features and performance, and I highly recommend it.

Bought this PSU for my MSI rig, stable power supple, not modular but the cables are not hard to manage, overall great PSU unit for a good price.

Went into my PC and lined up nicely with the screw holes. Didn't go too deep into the case. The cables were stiff and unruly however. The psu functions and the chemical smell mentioned in other reviews is present.

Mon thermaltake 650watt a rendu l'âme apres plus de ~12 ans de service. Donc je lai remplacer par le msi 650watt. Beaucoup de connecteur plat (il est pas modulaire mais les cables sont bien penser) Plus petit en taille que le thermaltake. Silencieux et avec un tres beau look. Tres bonne spécifications pour un excellent prix (en special a 89$ can) en plus certifier 80+bronze (ce qui est tres important,un psu sans cette mention ne doit pas etre utiliser) En espérant quil soit aussi durable que mon ancien thermaltake. En ten que technicien informatique depuis +20ans je ne voulais pas de marque chinoise batarde, et le msi fut un excellent choix.
