The liquid-cooled version of AMD’s Radeon Pro Vega Frontier Edition draws power from a pair of 8-pin PCIe power connectors as well as the PCI-Express slot power, giving it a total power output of 375W. The guys at PC Perspective have tested the card and their tests show that it is overdrawing power from the power connectors, with a peak power draw of a staggering 440W. This is with the power limit raised by 25% to stabilize a 7% overclock.
At its stock clock speeds the card remains under its 375W limit, drawing around 350W of power. The overdraw of power like that does not bode well for those who are looking to overclock the card and if the Radeon RX Vega is anything like this overclocking may not be that possible without overdrawing power.
