Short 18cm black cable converting dual 4-pin Molex to 8-pin PCIe GPU power

SMUGDESK

SMUGDESK 8Pin PCIe to Dual 4Pin Molex GPU Power Cable 18cm

SKU CH-AWMV-63QGW

Converts dual 4‑pin Molex outputs to an 8‑pin PCIe connector for graphics cards, with an 18 cm length for tidy internal routing

  • Powers 8-pin GPUs via dual Molex connectors
  • Compact 18 cm length keeps internal cabling tidy
  • Secure connectors prevent loose power connections
  • Plug-and-play setup requires no extra tools
  • Works with standard ATX supplies and midrange graphics cards

8-pin PCIe power adapter

This 18 cm cable converts two 4-pin Molex connectors from a standard ATX power supply into a single 8-pin PCIe plug. It is intended for builders whose PSU lacks the native 8-pin lead required by many mid-range graphics cards.

Bidirectional Molex-to-PCIe conversion

The adapter lets existing Molex outputs feed an 8-pin GPU port without replacing the power supply. Its short length keeps excess wire out of the airflow path and simplifies routing in compact cases.

Plug-and-play installation

Connect each Molex plug firmly into the PSU cables, then seat the 8-pin end into the graphics card until it clicks. Loose Molex pins are the most common issue; verify every pin is fully inserted before powering on.

Questions about this item

Will the 18 cm cable length or the Molex connectors need replacing after extended use?

The cable is built with durable wiring and secure connectors rated for standard ATX power delivery; no periodic replacement is scheduled.

What limits sustained power delivery through the dual 4 pin Molex to 8 pin PCIe adapter?

The adapter supports midrange graphics cards drawing power from two Molex outputs; the PSU’s Molex rail capacity is the practical ceiling.

Does the 18 cm converter cable generate noticeable heat or noise during all day operation?

Passive wiring produces no fan noise and negligible heat under normal midrange GPU loads.
