    Enough to power a 3900X and a RTX2070.

    No complaints in terms of performance. I do however, have an issue with the cables. They are all black, so no gross ketchup and mustard to worry about. However, I was kind of forced into buying sleeved cable extensions because the PCIE cable that came included has 2 plugs which made it push up against the glass side panel of my Meshify C Mini.

    Modular power supply and very good from what I heard of the RMx section of power supplies. Comes with a lot of cables however these cables come with in-cable capacitors along with being stiff in general which impeads cable management. Might consider getting less stiff cables in the future.

    Runs silent when it's not under load, but this power supply has some of the, if not THE thiccest cables I've seen. Had some trouble routing 24 pin cable to the motherboard.

    A high quality PSU, it has a pretty nice metal sticker bundled with it.

    Had an 80+ rating, modular, and was one of the cheaper options when I ordered it. Power supply prices seem to be pretty inflated in spring 2020, so I paid a bit extra for one I thought should last me well into the future, even with upgrades.

    Does what it is supposed to do, but the cables aren't the nicest.
