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