    Quiet, fully modular, and always on Rebate for some reason. I could have easily done with a 430W but this was on sale for a good price. great buy!

    Had it laying around and I actually have the 620W version of the M12II in this build. It cost me 64.99 three months ago. Still working strong today and it’s modular with black cables.

    At the time of purchase, it had a rebate going that brought its price down enough that it was a good deal for a fully modular 520w with a decent enough reputation to trust in a $500 build.

    Seasonic nothing much to see here great power supply very quite and fully modular and brone certified another great ebay find. Old build had a Corsair GS700 so i figured it was a worth upgrade seeing as that PSU is dirt old and wasnt modular.

    The only good modular PSU that doesn't cost £75+ It gives good clean power and was recommended by the pros such as JonnyGuru.
