PEGx Slot Power Limit Value Value
Sets the upper limit on power supplied by slot.
Power limit (in Watts) is calculated by multiplying this value by the Slot Power Limit Scale.
Values 0-255
PEGx Slot Power Limit Scale 1.0x, 0.1x, 0.01x, 0.001x
Or from the Intel 10th gen specification sheet:
16:15 0h RW/O Slot Power Limit Scale (SLS): specifies the scale used for the slot power limit value. BIOS sets this field and it remains set until a platform reset.
14:7 00h RW/O Slot Power Limit Value (SLV): Specifies the upper limit (in conjunction with SLS value), on the upper limit on power supplied by the slot. The two values together indicate the amount of power in watts allowed for the slot. BIOS sets this field and it remains set until a platform reset.
