i think you should familiarize with your amperage of each wall connectors. Mine is older condo and it appears all the sets of wall distributed around 2bedroom is controlled by 2 major circuit breaker. One time I tripped the circuit breaker and half of my miner lost power. Using that chance I decided to tinker with the patch panel to found out which switch will enable/disable which electrical items. There are separate breakers for lighting, walls sockets, dryer, kitchnen washer and dryer and I think I identified most of it. And each of them has marking of max amperage.
I've checked already by running test with the breaker and turning off and on the breakers to see witch rooms/outlets are affected. My basement is very small and the picture I posted shows 40amp 240V for that circuit (witch is used for my stove only).
Certainly don't just buy a "adapter" and use a standard surge protector with it, because the plug fits. Standard surge protectors are rated at 15A, in the USA at least. ... You're talking multiple rigs anyway, right? So you're going to want a PDU. Spend the money on it, before you blow everything up.
And as we've seen in this very thread ... Electricians don't know everything.
