Black 20 cm PCIe 8-pin female to dual 8-pin male power splitter cable

Vszerda

Vszerda PCIe 8Pin Female to 2x 8Pin Male Adapter Cable 20cm

SKU CH-S258-3RVMZ

Splits one PCIe 8-pin connector into two male 8-pin plugs using 18AWG cable over 20 cm length

  • Splits one PCIe 8-pin into two 8-pin connectors for graphics cards
  • 20 cm length fits tight chassis layouts without excess slack
  • 18 AWG PVC conductors handle GPU power loads without overheating
  • Female-to-male design plugs directly into existing PSU cable for quick installation
  • Not suitable for motherboard power — dedicated to graphics-card use only

PCIe 8Pin Splitter for Dual GPU Power

This adapter cable converts a single PCIe 8-pin female connector into two 8-pin male plugs. It is built for graphics cards that need two power inputs when the power supply only offers one. The 20 cm length keeps routing tidy inside compact cases. It suits builders adding a high-end GPU to an existing PSU.

18 AWG PVC Construction and Direct PSU Link

The cable uses 18 AWG conductors wrapped in PVC for durability and heat resistance. This gauge supports normal graphics card power draw without overheating. The design connects the GPU directly to the power unit, removing the need for daisy-chained cables that can limit current delivery. It cannot be used to power a motherboard.

Single 8-Pin Source Limits Total Wattage

The splitter draws all power from one 8-pin PSU output, so the combined load of both GPU connectors must stay within that port's rated capacity. Cards requiring more current than a single 8-pin line can safely provide are not supported. Builders needing independent 8-pin rails from the PSU must look elsewhere.

Questions about this item

Will the 18AWG PVC cable insulation degrade or need replacement after long-term use inside a case?

The 18AWG PVC construction is described as durable, heat-resistant and not prone to aging, so no scheduled replacement is expected under normal operation.

What is the maximum safe power draw before the 20cm splitter becomes the limiting factor?

The adapter simply passes through the existing PSU 8-pin capacity; it adds no extra current rating, so the limit is whatever your power supply's single 8-pin rail can deliver.

Does the 20cm length or 18AWG gauge cause noticeable voltage drop or heat when the GPU runs at full load all day?

The short 20cm run and 18AWG conductors keep resistance low, so voltage drop and heat build-up are minimal during sustained full-load operation.
