This PSU is solid, and you can sum up the level of quality relatively fast, even without the elaborate packaging and, yes, "sacks" to store your cables in... I'm not complaining, I just think its bizarre lol. Not sure if I bought a PSU or a bottle of Crown...

Make no mistake though, there are few occasions where product quality really does justify a little packaging bling, and when you buy a PSU, and you have the money to make sure you get the best brand on the market, you buy a Seasonic.


This isn't a con, but for those out there that haven't done a build in a few years, or even if you're just replacing an older PSU, there is one step that is a bit different. As most people know, this PSU, and most modern quality PSUs are fully modular in order to grant better cable management. You'll notice that on the Seasonic X 850 there is an upper row of labels, and a bottom row; indicating which output connectors you should use, such as MB, PCI-E, Peripherals etc..

When you connect your 24 pin ATX connector which will extend out from the bottom row, there is an additional connector on the PSU side of the cable that plugs into one of the connectors on the top row. Your PC won't boot if you forget to plug that in. If my description seems complicated or vague, don't worry, you'll see exactly what I mean when you get yours.
