Updated 1st page with list of most of the components with pics. I know I've missed a few things but I'll get to them later!

Phat, if you're less than an ace in CloD with that rig then shame on you.

just curious, how many amps on the 12v rails are you pulling in full load? HOW MANY IN ALL? that's an unreal system, congrats on being so extreme!!

also how many amps on the ac side (120v/240v)

thanks!

Im using 12x 30Amp 12V rails with each GPU using 2 dedicated rails per GPU (8x 30Amp) with another 2 rails for the 2x PCIE 12v molex on the MB. (~1450W 120Amps used in total for GPUs)

Then there's the 2x 30Amp rails for the 24pin + 2x 8pin CPU (CPU draws about 400W & 33Amps) + Accessories (26 fans and 4 pumps draw 20Amps)

Total ~175Amps roughly = ~2100W load pulling ~9.2Amps (2200W) @ 240v @ 95% efficiency
Officially we are good for about 2400W @ 240v per socket here so I am right on the limit with full load. Although the circuit breakers are all 15Amp (3600W) across a few power sockets on each circuit. So technically I can draw a little more than 2400W as long as there are no heaters/AC, Microwaves, Fridges etc running on the same circuit.

These are all guestimates but seem pretty close from my testing. I wasnt able to run the system stable with a 1500W and 1200W supply so I upgraded to 2x 1500W PSUs. The 1200W only had a couple 30Amp rails with the rest being 18Amp so it couldnt cope with the load and the system would shutdown.
