I would like to know how much power this build consumes approximately when on idle.

So far I have this:
CPU (24W) + GPU (4W) + SSD (0.35W) + Fans (1.5W) + RAM ( ? )

1. How much would 4 RAM sticks (4x16GB) consume?
2. Is this how I would calculate the total power usage? Am I missing something or is there anything I should add to get the total W?


Details:
Motherboard: X99M Killer 3.1

CPU: i7-6850K @ 1200MHz idle (VID at 0.770V) with adaptive voltage -- otherwise overclocked @ 4200 MHz with 1.278V
HWMonitor shows 24.00 W average idle usage for the CPU.

GPU: GTX 750Ti (Palit KalmX)
HWMonitor shows around 2.00% power usage. TechPowerUp says 4W is idle usage for this card.

SDD : One 2.5" (Samsung 840 Pro 256GB)
~ 0.32W at idle

FANS: 4 Fans with a total max power of 4.2W running at low speeds so it should be around 1.5W.

PSU: EVGA SuperNOVA 750 G2 with Eco Mode enabled so the fan does not spin.

RAM: 4x16GB with these:

@ 2800 - DRAM Voltage 1.250V


 
Solution


motherboard probably draws abut 20-50 watts

Thank you.

Do you know if there anything else that I might be missing, like the motherboard itself consuming energy?

CPU (24W) + GPU (4W) + SSD (0.35W) + Fans (1.5W) + RAM (2W) = 31.85W
