Short Y-split cable with black 8-pin PCIe plug and two 4-pin Molex connectors

Ruth's sister

Ruth's sister 18 cm 8-pin to dual 4-pin PCIe power cable

SKU CH-8V90-4XD7Q

An 18 cm Y-cable that splits one 8-pin PCIe connector into two 4-pin Molex plugs to power a graphics card from a PSU with only Molex outputs

  • Converts a single 8-pin PCIe connector into two 4-pin Molex plugs for graphics card power
  • 18 cm cable length keeps internal routing tidy inside compact cases
  • Y-split design delivers power to dual 4-pin inputs from one PSU lead
  • Supplied as a new component ready for immediate installation
  • Model reference 280903 identifies the exact cable variant

What this cable does

This 18 cm Y-shaped adapter converts a single 8-pin PCIe connector from a power supply into two 4-pin Molex plugs, letting older PSUs feed graphics cards that require dual 4-pin power inputs. The wire length is about 17 cm and may vary slightly between batches.

Who should use it and who should not

Builders with a modern PSU that already provides native 8-pin or 6+2-pin PCIe leads will not need this adapter. It is also unsuitable for anyone whose graphics card demands more than two 4-pin connectors or who needs a longer reach than roughly 17 cm.

The deciding specification

The cable bridges an 8-pin PCIe source to dual 4-pin Molex outputs, so the only thing that determines fit is whether your power supply has a spare 8-pin PCIe port and your graphics card accepts two 4-pin Molex plugs.

Questions about this item

What does the 18 cm length mean when I route it inside my case?

The 18 cm Y-shape gives a short run from the PSU's 4-pin Molex connectors to the graphics card's 8-pin socket, keeping cable clutter low in tight builds.

How does the 8-pin to dual 4-pin Molex interface work in practice?

It converts two peripheral 4-pin Molex plugs from the power supply into a single 8-pin PCIe connector for the graphics card.

What clearance do I need to fit the 17 cm cable and Y-splitter?

Allow roughly 17 cm of wire plus the splitter housing; the short length suits compact cases where longer cables would bunch up.
