Power adapter for GPU upgrades

This 8-pin PCIe to dual 4-pin Molex cable lets a graphics card draw power from two spare Molex connectors on an existing power supply. It targets builders who need to add a card that requires an 8-pin connector but whose PSU lacks one.

Maximum continuous power rating

The adapter is specified for 180 W maximum power delivery through 18 AWG pure copper conductors. This single figure determines whether the cable can support a given graphics card without exceeding its thermal limits.

Sustained-load behaviour

At the rated 180 W the 18 AWG wires and connectors are designed to handle continuous current without overheating. The 18 cm length keeps voltage drop low during extended gaming or compute sessions.

Questions about this item

What does the 180 W rating mean when the cable is installed in a system?

It indicates the maximum continuous power the adapter can deliver from two Molex connectors to an 8-pin PCIe graphics card without overheating.

Which connectors are used and what limits do they impose?

The cable uses a male PCIe 8-pin plug and two female Molex 4-pin sockets; each Molex leg is rated for 15 amps on 18 AWG copper wire.

What clearance is needed to route the 18 cm cable inside a case?

The 18 cm length (7.08 inch) requires minimal space between the power supply Molex leads and the graphics card 8-pin socket.
