- System power supply requirement: 450W (one 75W 6-pin PCI Express connector recommended) Ultra Durable VGA board provides dramatic cooling effect on lowering both GPU & memory temperature by doubling the copper inner layer of PCB. Gigabyte Ultra Durable VGA can lower GPU temperature. Ultra Durable VGA board reduces voltage ripples in normal & transient state, thus effectively lowers noises & ensures higher overclocking capability. Gigabyte Ultra Durable VGA graphic accelerators improve overclocking capability. Ultra Durable VGA board allows more bandwidth for electron passage & reduces circuit impedance. The less circuit impedance, the more stable flow of current & can effectively improve power efficiency. Gigabyte Ultra Durable VGA can lower power switching loss.
