What is TGP? (Total Graphics Power)
TGP is the amount of power, in watts, that a graphics card is designed to draw under full load. You’ll also see it called TBP (board power) or loosely TDP — for buyers they mean the same thing: how hungry the card is.
Typical RTX power draw
Reference figures range from about 115W (RTX 4060) and 145W (RTX 5060) through 200W (RTX 4070) and 250W (RTX 5070), up to 320W (RTX 3080, 4080) and 360W (RTX 5080). Factory-overclocked models can draw more. See every card’s figure in our RTX GPU comparison.
Why it matters
Your PSU: NVIDIA’s recommended total system power is around 550W for an RTX 4060, 650W for an RTX 4070 or 5070, 750W for an RTX 3080 or 5070 Ti, and 850W for an RTX 5080. Some RTX 30 cards also produce short power spikes, so a quality PSU matters as much as its wattage. Heat: almost every watt ends up as heat in your room — noticeable in a Singapore HDB bedroom without aircon. Electricity: at roughly 30¢/kWh, 150W extra for 3 hours a day adds about $50 a year.
Performance per watt
Newer cards usually deliver the same performance for less power. An RTX 4070 matches an RTX 3080 in games while drawing about 120W less — a real advantage in a hot climate. Every one of our gaming PCs in Singapore ships with a branded PSU sized for its graphics card.
