    Excellent per supply when looking to upgrade

    Did exactly what I needed. I wanted to put a modern video card in an older case and this fit all the requirements and then some. I'm happy that this supports the PCIe 5.1 standard.

    Awesome power supply for less power hungry builds

    I bought this power supply because I had a less power hungry system from an older chipset. Luckily the Skylake chipset and the GTX 1060 from sister's system didn't need much juice to have it up and running. The fan is pretty quiet and the cost to performance ratio is nice. The 140mm fan is pretty nice with big blades with the embossed MSI Dragon logo on the undercarriage of the power supply depending on your configuration of course. It's a small and compact power supply and the power switch was snappy and looked durable even though that's probably not something most people look at these days.

    reliable and easy to install

    Pick this PSU for my friends build. Currently he has AMD Ryzen 7 7800X3D paired with 4060TI and his old one gave up on him. Since my build has another MSI psu, I didn't hesitate to get him this one. It is really stable and reliable. The price point was also why we pick this psu as well. It is also also very quite compared to what he had before.
