BENCHLAB PCI-E Slot Power Measurement Adapter, Black (BL-AD-P4X16-05)

The BENCHLAB PCI-E Slot Power Measurement Adapter sits between the motherboard slot and the graphics card and feeds the slot power from an external PCIe 6-pin source. Connected to a BENCHLAB, that lets you measure the current, voltage and power a card draws through its PCIe slot. The adapter is rated for PCIe 4.0 x16.

Properties

• Type: PCIe x16 slot power measurement adapter
• Interface: PCIe 4.0 x16
• External input: PCIe 6-pin, 12 V
• Switchable rails: 12 V, 3.3 V and 3.3 VAUX
• For use with: BENCHLAB

Why measure slot power

A PCIe slot can deliver up to 75 W to a graphics card. BENCHLAB measures every external power cable of a card, but it cannot see the power supplied through the slot itself. This adapter closes that gap: the slot power comes from a dedicated BENCHLAB cable, so BENCHLAB reports it next to the PCIe and 12VHPWR readings.

Jumpers for each rail

For the 12 V, 3.3 V and 3.3 VAUX rails you choose between external and slot supply by moving the jumpers. In the up position the power comes from the external input, in the down position from the motherboard slot. The 12 V jumper is a double jumper and both parts need to be set correctly.

How to set it up

• Install the BENCHLAB as usual, typically between the motherboard and an Open Benchtable.
• Insert the adapter into the motherboard PCIe slot.
• Connect the 6-pin power input of the adapter to a dedicated cable from the BENCHLAB.
• Install the graphics card in the adapter.
• The BENCHLAB software reports the slot power automatically.
