J&D 8 Pin PCIe to 2 x 4 Pin LP4 Molex Power Cable Adapter (2 Pack), 6 inch / 15 cm, Black

Bottom line: The J&D 8 Pin PCIe to 2 x 4 Pin LP4 Molex Power Cable Adapter: 18 AWG oxygen-free copper with braided shielding, not thin unshielded wire; main trade-off: adapter splits load across Molex rails, so PSU headroom must be checked first.

Pros & Cons

Pros

  • ✓ 18 AWG oxygen-free copper with braided shielding, not thin unshielded wire
  • ✓ 6 in / 15 cm keeps slack out of the case behind the GPU
  • ✓ Feeds an 8-pin PCIe card from two spare 4-pin LP4 Molex leads
  • ✓ Vendor lists fit for most 8-pin cards including ASUS, Gigabyte, Sapphire

Cons

  • ✗ Adapter splits load across Molex rails, so PSU headroom must be checked first
  • ✗ 6 in reach is short if your Molex leads sit low in the case
  • ✗ No PCIe 12VHPWR or 6-pin variant, so newer cards need a different cable
  • ✗ Molex-to-PCIe is a stopgap; a PSU with native 8-pin is the better fix
