Short black power cable with two white Molex plugs merging into one black 8-pin GPU connector

SMUGDESK

SMUGDESK Dual 4 Pin Molex to 8 Pin GPU Power Cable 22cm

SKU CH-ADND-S7RDF

Converts two Molex connectors into one 8-pin PCIe power plug for graphics cards, 22 cm long for tidy case wiring

  • Converts two Molex connectors to one 8-pin PCIe GPU power plug
  • 22 cm length keeps internal cabling tidy in most PC cases
  • High-conductivity copper core delivers steady current under heavy GPU load
  • Reinforced moulded connectors maintain tight contact and resist accidental disconnection
  • Plug-and-play adapter solves missing native PCIe power ports on older PSUs

Power adapter for GPU upgrades

The SMUGDESK cable converts two 4-pin Molex connectors into a single 8-pin PCIe power plug for graphics cards. It targets builders whose power supplies lack native PCIe connectors but have spare Molex leads. The 22cm length suits compact chassis layouts and keeps internal wiring tidy. No modification is required for installation.

Sustained load stability

High-conductivity copper cores and heat-resistant insulation maintain steady current delivery during extended high-load GPU operation. Reinforced molded connectors resist loosening from vibration or thermal cycling, reducing the risk of intermittent power faults. The short run minimises voltage drop across the adapter itself. It is a passive wiring solution with no active regulation.

Replaces missing native PCIe power

This adapter replaces the need for a power supply with built-in 8-pin PCIe outputs when adding or upgrading a discrete graphics card. The upgrade is worthwhile when the existing unit has sufficient wattage and Molex headers but lacks the correct GPU connector. It does not increase the power supply’s total capacity or add protection circuits. Builders needing multiple GPU power cables or higher current ratings than Molex can safely provide should not use this adapter.

Questions about this item

How much heat does the 22cm copper cable generate when the GPU runs at full load all day?

The high-conductivity copper core and heat-resistant insulation are designed to maintain stable current transmission and reduce overheating risk during long periods of high-load operation.

What existing power connectors must my power supply have for this adapter to work?

Your power supply must provide two available 4-pin Molex male connectors to plug into the dual ends of this adapter cable.

Will the molded 8-pin PCIe connector fit securely on an older graphics card that uses the same interface?

Yes, the precision-molded connectors are built for tight contact to prevent loose plugs and unstable power delivery on any standard 8-pin PCIe graphics card port.
