  • Delivers up to 600 W through 16 AWG tinned copper conductors
  • PCIe 5.0 12VHPWR connector powers RTX 3090 Ti 4080 4090 graphics cards
  • Three 8-pin (4+4) male plugs draw from Corsair Great Wall Thermaltake modular PSUs
  • 70 cm length with four cable combs keeps routing tidy
  • 12+4 pin male connector mates securely with GPU 12VHPWR port

Product purpose

This BFKK internal power cable converts three 8-pin (4+4) male connectors from a compatible modular power supply into a single 16-pin 12VHPWR plug. It is built for GeForce RTX 3090 Ti 4080 4090 graphics cards and measures 70 cm in length with 16 AWG tinned copper wire.

Compatibility scope

The cable only works with Corsair Great Wall Thermaltake modular PSUs that provide 8-pin (4+4) CPU ports and requires three free such ports on the power supply. It does not support the 12-pin connector found on standard RTX 3090 cards and cannot be used with power supplies from other brands.

Deciding specification

The assembly is rated for a maximum output of 600 watts through its 12VHPWR 16-pin (12+4) male connector. Buyers must verify that their graphics card power draw stays within this limit and that their PSU has three available 8-pin (4+4) ports before purchasing.

Questions about this item

Does the 16 AWG wire and 600 W rating keep the cable cool during all-day load?

The 16 AWG tinned copper conductors are rated for up to 600 W, which is the design limit for the 12VHPWR connector on RTX 4080 and 4090 cards.

My PSU is a Corsair unit with 8-pin (4+4) CPU ports — will this cable plug straight in?

Yes, the cable uses three 8-pin (4+4) male plugs that match the CPU-style ports on Corsair, Great Wall and Thermaltake modular PSUs.

Can I run an RTX 3090 Ti alongside older 8-pin GPUs on the same PSU using this cable?

This cable occupies three 8-pin (4+4) PSU ports to feed one 12VHPWR GPU, so the PSU must still have enough spare ports for any additional cards.
