Kind of feels like if you spend $40K on your GPU setup, you don't want to cheap out on the PSU.
Still, you're right, I have a 1200W PSU for a single RTX Pro 6000, cost ~500 something, so still the PSU shouldn't be that large part of the total budget.
Funny thing is, you don't really want to just plug that into a wall socket. You want an uninterruptible power supply that can keep the machine running for the 5 to 8 minutes you need to get to it and shut it down safely during a power cut.
But you'll find most household power sockets aren't actually rated for the kind of power these things draw at peak. If you go for a dual GPU you're going to want to sustain a higher current. Think washer / drier / fridge kind of hookups for the UPS and that rig.
You spent $42K on the rig, you're also going to need to get an electrician in and have the electrical hookup seen to. The single 4090 I'm running put me right up to that edge where I could use a standard electrical hookup with a 1000w UPS.
So another $1K for the UPS, and $500 worth of electrical work (or more if they have to up the switch to 200 amps, for example).

Not for the faint of wallet.
