Edit: I also didn't notice the case also came with a PSU. That's awesome.
The PSU sticker says 80 Plus Platinum which is amazing, but it makes me wonder how all that is so cheap.
Well, $195 isn't cheap where it came from; China, plus it's second-hand.
Also, those Julongfengbao 2000W/2500W PSU are (
were) being sold for something less than $40 brand new.
For that price-range, don't count on the label's ratings including the 80+ Platinum sticker.
The good news is: those are "
well-tested" for years and from the looks of the sample images, haven't caused fire... yet.
if he does xelis mining with 3060 ti or 3070 they pull about 100 watts each.
so the rig would do 800-900 watts against a 2500 watt psu.
it should mind you should be fine.
of course any mining gear can fail.
