Reddit reviews Leviton 2620 30 Amp, 250 Volt, Flush Mounting Locking Receptacle, Industrial Grade, Grounding, V-0-MAX, Black

i would run 30a 240v lines, 2 for now, 3 if you want more space in the future. thats 10amp wire, with 2 hots and a neutral, aka 10/2. same as dryer wire, its not too pricey. you would run that to a NEMA L6-30P socket, and get a PDU such as PDUMV30HV and plug each psu in to it using these plugs: IEC-320-C14 to IEC-320-C13

1. Buy this plug- https://smile.amazon.com/gp/product/B00002NAT9 (have electrician swap the outlet)
   
   
2. Get a PDU- I use this one . https://smile.amazon.com/gp/product/B0046JS1ES (buy the used ones for ~$315 or so)
   
   
3. Snag a few of these cables to run from PDU to PSU's - https://smile.amazon.com/gp/product/B008ABO7PA
   
   
   The PDU is 30amp, but good luck finding a 50amp PDU. You can run ~6ish mining rigs off of this setup (6 GPU per rig)

Below are most of parts that are needed for the kettle and electronics controller. I don't think I forgot anything. You would obviously need to be a little handy and have some tools like files, a drill, etc.

Thats a twist lock with the correct c13 end for a computer / bitmain power supply yeah. 14 gauge is nice too... thats what I use from my PDU's to each machine. The 3 prong wont fit the outlet in your picture though, you'll need to rewire it to something like this:
https://www.amazon.com/Leviton-2620-Receptacle-Industrial-Grounding/dp/B00002NAT9/ref=pd_lpo_vtph_23_bs_t_1?_encoding=UTF8&psc=1&refRID=AB56ZCHD7BGJW6QN1DGH
Should be a really simple job for any electrician... just need a box, the outlet and a few minutes.
If you switch out the outlet you could also run one of these:
https://www.ebay.com/itm/Tripp-Lite-PDU-Basic-208V-240V-30A-20-Outlet-15-ft-Cord-PDU1230/112826455467?epid=1837218544&hash=item1a44fb15ab:g:Nz4AAOSw2cNakT4K
which will let you run the number of miners that outlet is capable of (30 amp). 30 amps * 80% = 24 usable amps. Each miner runs around 6amps on 240, so 4 s9's safely from the one outlet (through a PDU of course).
