its 220 volt, 20 amp.

google NEMA 6-20R

you could buy a NEMA 6-20P plug at a hardware store and just cut the end of the power supply cord and put it on. ONLY if you are SURE youll do it correctly of course. no sense dying over it..

where are you? Ive never hear of a whole house hot water heater with a plug. all that Ive seen (hundreds in my prev job in construction) were hard wired 220 volt.

Thanks that's exactly the information I needed. I'm currently in Florida living in a 3 bedroom apartment but before this I had only seen this type of plug in my grand parents trailer years ago. I'm used to soldering ect but have no idea how legs ect work with home power wiring. I i'm surprised this isn't a common question on here with power cords from china on the cheap all over the net lol. I love the idea of 220v since the current will drop allowing me to go back to 6 GPU's(had problems with breaker before not PSU) and profits will increase slightly which is good since it's been pretty grim lately.

I would really like to find a cable I don't have to butcher since this one looks euro/specific in case I move forcing me back to 120v or ever sell these power supplies. The closest I have found is here:

If the earth/ground(rounded prong at bottom) was flat like the top two and parallel like them it would probably fit right into the back of my PSU enabling the 6-20P without mods...if I find something I'll link but either way will keep the thread updated for others who may go my route.
