    Works like a charm! I liked how the wires came in a anti-staticbaggy to protect them.

    Previous online order that arrived earlier that day had a rattle. Went to store and wanted to replace with same item due to a great price. Unfortunately store did not have the same item in stock. Customer service offered options of return and pick up in another location, or reorder online. Great customer service in returning item. Hassle free.

    High Quality PSU

    High Quality PSU. Just don't mount it with the fan pointing down towards the floor, as this will cause the fan to start making an awful noise after a few days. Wish this wasn't the case, as (see picture) my PC has a vent grate underneath itself and only has a small gap below the motherboard for airflow. Otherwise seems to be of very high quality and made of high-quality parts. Almost my entire PC is built with MSI parts, so that says what I think of their stuff.

    I used this in my build & is easy to set up, the best thing is that this is a PCiE. 5.0-5.1 ready. So this already has the cable for new GPUs

    The MSI MAG A850GL PCIE5 850W power supply is an excellent choice for anyone building a modern, high-performance PC. From the outset, it delivers rock-solid power stability and clearly feels engineered with current and next-generation hardware in mind. The native PCIe 5.0 (12VHPWR) support is a major advantage, eliminating the need for adapters and making it ideal for newer GPUs. Build quality is outstanding. The fully modular design makes cable management clean and straightforward, and the included cables feel durable and well-finished. Installation was easy, and the unit fit perfectly in a standard ATX case. The 80 Plus Gold efficiency rating is evident in both performance and thermals, keeping power delivery efficient while maintaining low heat output. In day-to-day use, the A850GL operates quietly, even under heavy load. The cooling system is well-tuned, with the fan rarely becoming noticeable. Voltage regulation is stable, providing confidence when running demanding workloads or extended gaming sessions. Overall, the MSI MAG A850GL PCIE5 850W offers excellent reliability, forward-looking features, and strong performance at a very competitive price point. It is a dependable power supply that inspires confidence and easily meets the needs of modern PC builds.

    Being fully modular, I only installed the necessary cables, which greatly facilitated the airflow and aesthetics in my cabinet. Voltage stability: I have monitored the 12V and 5V rails with software and the deviation is minimal, providing total security to my GPU and CPU.

    I have used this PSU in a few builds, it just works. It's modular so you only need to use the necessary cables which makes cable management a breeze. It's quiet and just performs well.

    Great modular power supply. Has weird pin layout

    Very modular which is cool, but I noticed that the some of the pins are in a weird configuration. I forget which one at this point, but I was looking to buy shorter cables, and one of the connections was difficult to find since it was a weird amount of pins going into the PSU. Still a great power supply that has given me no issues.
