  • Two LP4 male connectors supply power from existing PSU
  • 56 oz lightweight adapter adds minimal strain to connectors

Purpose and Compatibility

This StarTech.com LP4PCIEX8ADP adapter converts two 4-pin LP4 connectors from an existing ATX power supply into a single 8-pin PCI Express connector for a graphics card. It suits builders who need to power a PCIe video card without replacing the current power supply.

Sustained Operation

The 18 AWG conductors carry the load required by an 8-pin PCIe graphics card under continuous use. Reliable delivery depends on the host power supply providing adequate current through both LP4 sources.

Build and Connectors

RoHS-compliant materials and a lifetime warranty reflect durable construction. The 6.1 in length keeps routing tidy inside typical chassis while the 2-tone male-to-male ends ensure clear polarity identification during installation.

Questions about this item

How much heat or power loss should I expect from the 18 AWG wires when the adapter runs all day?

The 18 AWG conductors are rated for the current an 8-pin PCIe connector delivers, so heat stays minimal under normal GPU loads.

My power supply only has Molex LP4 plugs — will two of those feed this adapter correctly?

Yes, the adapter takes two 4-pin LP4 male connectors from the PSU and combines them into one 8-pin PCIe male plug for the graphics card.

Can I keep using my older PSU that lacks native 8-pin PCIe leads with this cable?

Exactly — it converts two legacy LP4 outputs into the 8-pin PCIe connector a modern video card requires, avoiding a PSU upgrade.
