Hey guys - All help is super appreciated!!!

I have a 13gpu (RX580's) set up

I'm powering the motherboard and 1 GPU from a 750w EVGA

and the 12 remaining from 2 x DPS-1200w HP Server psu's

Problem is the server psu's sound like hoovers, when i first powered them up i shit myself and ran to the other side of the room, sounded like it was going to take off/blow up

I cannot remember whats coming our from the wall as I'm at home now but im pretty sure its almost maxing it

This is my first time mining and i went for the server psu as it was the cheaper and more readily available option

The miner is set up in my home office where i answer the phone and I cannot hear or even think when its running Sad

My question is now, do i get another server psu to share the load?? Will that lower the noise a lot? Or do I bite the bullet and get some regular PSU's??

Another arse is the 2 x 1600w i probably should get are out of stock - as are the other option of 3 x 1200w's (probably around 2-4 weeks)

The only thing i can get now is 1000w but dont know how to set that up ( i got a feeling 3 will not be enough) and not sure if i can run 4 all connected on connect 2 together to run 6 cards and andother 2 seperate for the other 6 cards or anything like this

I'm in the UK so each plug socket can take 3KW and my breaker in the board is even larger ththis
