Black sleeved 16-pin to triple 8-pin GPU extension cable with combs, 30cm

Vszerda

Vszerda PCIe 5.0 16-Pin (12+4) to 3x8 PCI-E Sleeved Extension Cable 30cm

SKU CH-AP71-V28DJ

PCIe 5.0 12+4-pin to triple 8-pin sleeved extension cable with combs for RTX 3090 Ti, 4080 and 4090, 30 cm long

  • PCIe 5.0 16-pin (12+4) powers RTX 3090 Ti 4080 4090 GPUs directly
  • 16 AWG tinned copper handles 600 W continuous load without overheating
  • 30 cm sleeved extension keeps cable routing clean inside the case
  • Included 12+4 pin cable combs organise wires for a tidy build
  • Converts three 8-pin PSU cables to 12VHPWR so no PSU swap is needed

12VHPWR extension for RTX 40-series

This cable bridges a standard triple 8-pin PSU output to the 12+4-pin 12VHPWR connector found on RTX 3090 Ti and RTX 4080/4090 graphics cards. It is intended for builders upgrading a GPU without replacing the power supply. The 30 cm length suits typical mid-tower routing. The product ships new with three dedicated cable combs included.

600 W headroom with triple 8-pin input

Rated for over 600 W when all three 8-pin plugs are populated, the 16 AWG tinned-copper conductors stay cool under full load. Using fewer than three 8-pin sources reduces available power and stability. The extension design means it must attach to existing PSU cables; it does not connect directly to the PSU. A 35 mm straight run from the connector is advised before any bend.

Cable combs and sense-wire protection

Three 12+4-pin combs align the sleeved wires for a cleaner interior appearance. The combs slide along the cable but require gentle force to avoid damaging the thin sense wires inside the connector. Proper seating is critical: the plug must sit completely flush with the GPU socket, and the connection should be re-checked after routing to prevent accidental dislodgement.

Questions about this item

Will this 12+4 pin extension work with my existing 8-pin PCIe cables from an older PSU?

Yes, the cable converts three 8-pin PCIe connectors into one 12+4 pin plug, so you can keep your current PSU cables and reach RTX 3090 Ti, 4080 or 4090 cards.

How do I verify the 12VHPWR connection is fully seated after routing the 30 cm extension?

The connector should sit completely flush with the GPU socket with no visible gap; re-check after fitting the three supplied cable combs to ensure nothing has loosened.

What comes in the pack and do I need to buy extra combs or cables?

The box contains one 30 cm 16-pin (12+4) to 3x8-pin sleeved extension and three dedicated 12+4 pin cable combs; no extra parts are required.
