  • Reliable and Efficient - MSI MAG A650BN Delivers
Size: 650W Style: MAG A650BN
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. ... show more

  • good value.
Size: 650W Style: MAG A650BN
its not modular! but, it works well, quiet/silent. and good value. only has one daisy chained 8 pin connector, and one 8 pin cpu. so not something youd want to use on a component drawing 250w+ or if you have multiple components needing 8 pin pcie.

  • Always a great pickup
Size: 550W Style: MAG A550BN
I’ve used this unit a few times. It’s An always decent and reliable power supply for budget oriented builds. Tier c on power supply tier list. This is a great pairing for any 250w graphics cards and ryzen 5 cpus. It runs quiet as I haven’t noticed the noise. Clean look and black cables. Highly Recommend. ... show more

  • Great Budget PSU if you have the space!
Size: 550W Style: MAG A550BN
Non-modular, so it takes up a lot of space, the connectors are firm and ugly, and the fan is relatively loud. However, for $50, its a great PSU that wont blow up.
