Ruth's sister 0577 18cm 8-pin PCIe to dual 4-pin Molex power cable

SKU CH-M5SQ-FM138

An 18 cm Y-cable that converts one 8-pin PCIe connector into two 4-pin Molex plugs for graphics-card power

  • 18 cm cable keeps GPU power routing tidy inside compact cases
  • Y-split design feeds an 8-pin PCIe connector from two 4-pin Molex leads
  • 100 % new build quality ensures reliable current delivery to graphics cards
  • Compatible with AMD and NVIDIA video cards using standard 8-pin power inputs
  • 0577 model supplied in protective bubble bag without retail packaging

18 cm 8-pin PCIe to dual Molex adapter

This 18 cm Y-shape cable converts a single 8-pin PCI Express connector from the power supply into two 4-pin Molex plugs. It is built for graphics cards that require an 8-pin input but are installed in systems with only Molex leads available. The 5 V pin on each Molex connector is not connected. Condition is new.

Builders with spare Molex leads

Suits anyone adapting an existing PSU without 8-pin PCIe cables. Not suited for installations that need a longer reach than 18 cm, or for powering devices that require the 5 V line on the Molex connector.

18 cm fixed length

The cable measures approximately 18 cm end to end, which determines whether it can span the gap between the power supply and the graphics card in a given chassis. No other length option is offered.

Questions about this item

Will the dual 4-pin Molex connectors on the 0577 cable need replacement after repeated plugging cycles?

The connectors are standard LP4 4-pin Molex and 8-pin PCIe types rated for typical mating cycles; replace only if pins loosen or show visible wear.

What is the practical length limit of the 18 cm cable when routing power to a graphics card in a full-tower case?

At 18 cm the cable reaches from a PSU mounted at the bottom rear to most mid-range GPU power sockets; longer runs require a different cable.

Does the 0577 adapter generate noticeable heat or noise when the graphics card draws full load all day?

The passive copper wires produce no noise and only minimal resistive heat under normal GPU loads; no active cooling is needed.
