WTF PSU is that? Really 1500W? 
Corsair AX1500 is 1500W, RM1000 is 1000W and so on.
Accord is also really 1500W or 500W?
Hmm, I noticed that each additional card would add marginally more to my draw from the wall. Not as much as you're reporting - maybe about 5W/GPU (that is 1 GPU adds 130, 2 adds 135 (265 total), 3 adds 140 (405 total), etc.). I just chalked it up to extra CPU, lowered PSU efficiency, or something. Are you saying 2 cards bumps you by 260W, but 4 cards bumps you by 640W?
370W and 720W total.
Your numbers are a bit off, then - what PSU are you using? Most are most efficient around 50% load (something like that, going from memory).

I need a help.
My rig is Asus Z270-P/Celeron/16Gb/ Vega56 with 64 BIOS
I use this instruction:

If I install 2 GPU - 130W per card
If I install 4 GPU - 160W per card
Why?
