Manufacturer description

The Sirlyr PSU Cable Extension Kit gives your build a clean, all-white look without changing your power supply's original cables. You get six braided extensions: one 24-pin ATX lead for the motherboard, two 8-pin (4+4) EPS leads for the CPU, and three 8-pin (6+2) PCIe leads for the graphics card. Each cable is 16AWG tinned copper wrapped in bright white nylon braid. Sirlyr says the braid will not yellow from case heat over time. The PCIe connectors use gold-plated terminals, which are rated for stable power delivery to high-draw cards. The main feature is the one-way bend layout. Longer…

Frequently Asked Questions

What cables come in the Sirlyr extension kit?

Six cables: one 24-pin ATX for the motherboard, two 8-pin (4+4) EPS for the CPU, and three 8-pin (6+2) PCIe for the graphics card.

Are these full replacement PSU cables or extensions?

They are extensions. They plug into the end of your power supply's existing cables, so they work regardless of the PSU's modular pinout.

What wire gauge does the Sirlyr kit use?

All cables use 16AWG tinned copper, and the PCIe GPU connectors have gold-plated terminals.

Will this work with a GPU that uses a 16-pin 12VHPWR connector?

The kit includes 8-pin (6+2) PCIe leads only, not a 16-pin 12VHPWR or 12V-2x6 cable. It suits cards with standard 8-pin or 6-pin power inputs.

What warranty does Sirlyr offer on this kit?

Sirlyr offers a one-year warranty and free replacement if a cable has a problem. Contact the seller through the listing to make a claim.
