This is a hard money call for me.

15000 watt model will do my 3 whatsminer's which take 10000 watts and it will do a 2000 watt miner say the inno t39
that is about 220th of my 900th but it is 1925 usd.
the cheapo amazon is 179 and will do some the s17 the t17 the inno t39 the avalon 1041
but I do not think it can do the 3300-3400 watt units . I could order five of them for 900 but they take up space. etc.
At the moment both inno's dropped out 24 + 39 = 63 th and part of the m21s dropped out 18th = 81th along with 2 s9's
81th + 27th = 108th. I know it is power fluxes since the amazon linked regulator shows we dropped to 190 volts
when this happens some psus won't work and I get drop outs.
