How many watts does GeForce MX550 use?
Short answer
GeForce MX550 draws up to 25 W under gaming load — that is its rated TDP; short spikes can reach about 35 W. A build with a mid-range CPU needs a 400 W power supply or more. At 3 h of gaming a day the card uses ≈2.3 kWh a month (≈$ 0.39).
| TDP (rated, gaming) | 25 W |
