POWER SUPPLY REQUIREMENT FOR GRAPHICS CARDS
#1
PSU consumption is a crucial question of all PC users.


As the processing power of graphic cards has increased, so has their demand for electrical power. Present graphic cards tend to consume a great deal of power. While CPU and power supply manufacturers have recently moved toward higher efficiency, power demands of GPUs have continued to rise, so today graphics cards have become one of the most power-hungry component, even though cpu still hold the second position in this rating.

Although power supplies are increasing their power too, the bottleneck is due to the PCI-Express connection, which is limited to supplying 75 Watts. Present graphics cards with a power consumption over 75 Watts include a combination of six-pin (75W) or eight-pin (150W) connectors since the remainder of the graphics card’s TDP thus needs to come from its 6-pin or 8-pin PCI-E connectors.
