My current PSU is an RM850x, which I think would handle it fine, but unfortunately the case I'm potentially building in will only fit an SFX or SFX-L PSU, which limits me a bit. (There is a 1000W available, but it's pricey, but this may be the route I take).
 
Ran it through the EVGA power meter 550W would suffice based on a 5950x not overclocked & 3070 assuming one SSD and one mechanical drive.

Something like the...

Corsair SF Series SF600 SFX 600 W Fully Modular 80 Plus Gold Power Supply Unit


That’s £ 108 inc VAT with free delivery at one online store.

I think the SF600 only has 2 PCI 6+2 connectors so wouldn't handle both cards
 
5950X maxes at 140W.
3070 draws up to 220W in average, with transients exceeding 350W.
Throw in 50W for other parts.
2070 Super would draw about same to 3070.

My bad, didn’t realize he wanted to run two cards. I thought it was either 3070 or 2070 S.

A 5950x not overclocked and 2x 3070’s with 1 SSD and 1 mechanical drive would be 750W. Same wattage if running 2x 2070 Super.

I wasn’t aware you could run two different GPUs in SLI. Anyway a Corsair SF 750W is £ 134.75 inc VAT and free delivery at one online store. It’s got 4x PCIe connectors.

Edit: Just been googling you can’t SLI a 3070 as it doesn’t support it.

I don't plan to SLI them. Blender uses any and all GPUs attached to the system, regardless of how they're connected.

It's kinda like mining, except actually productive.

OK well the EVGA power meter suggests 750W for either two 3070’s or two 2070’s in SLI but I guess that would cover both in non-SLI.

That Corsair SF 750W should be enough. Here’s the power meter if you want to check yourself...
