Black 15cm adapter cable with dual 4-pin Molex plugs and a PCIe 8-pin 6+2 connector

Vszerda

Vszerda Dual 4Pin to PCIe 8P 6+2Pin Power Adapter 15cm

SKU CH-MTTH-C79HC

Connects a PCIe 8-pin graphics card to two Molex 4-pin power supply leads, 15 cm long

  • Powers PCIe graphics cards from legacy supplies
  • Dual Molex 4-pin inputs feed a single 8-pin output
  • 15 cm length keeps cable routing tidy
  • Supports both 5 V and 12 V rails
  • Enables modern GPU use on older PSUs

Power adapter for older PSUs

This Vszerda cable converts two Molex 4-pin connectors into a single PCIe 8-pin 6+2 plug. It lets a power supply without native PCIe outputs run a modern graphics card. The adapter is intended for builders upgrading a GPU while keeping an existing PSU. It supports DC 5 V and 12 V delivery.

Thermals and power draw

The cable carries 12 V power from the PSU to the graphics card without active components. Heat and noise depend entirely on the power supply and GPU load, not on the adapter itself. Power draw is determined by the connected card and the PSU rating. The 15 cm length keeps voltage drop minimal in normal use.

What the bundle changes

Only the adapter cable is included in the package. No extra connectors, sleeves or software are supplied. The dual Molex ends must plug into separate PSU rails for balanced current. Builders needing more PCIe plugs or different lengths must source additional cables separately.

Questions about this item

How do I connect the two 4-pin Molex plugs to the power supply correctly?

Plug each 4-pin Molex connector into separate power supply cables, not the same daisy-chain line, then attach the 6+2-pin PCIe end to the graphics card.

Will the Molex connectors or cable insulation degrade over time?

The connectors are standard Molex 4-pin and PCIe 6+2-pin types; no maintenance is required unless physical damage or loose pins appear.

What power limit does the 15 cm adapter hit first under continuous load?

The dual Molex design supports DC 12 V delivery up to the PCIe 8-pin specification, so the power supply’s own 12 V rail capacity is the limiting factor.
