What it is
This two-pack of 12-inch extension cables links a power supply's EPS 8-pin output to a motherboard's 8(4+4)-pin CPU socket. Each cable carries a 500 W rating on standard 18 AWG conductors insulated to UL1007. They are intended for desktop builders who need extra reach between the PSU and the CPU power header.
Build and connectors
The black jacketed wires terminate in a keyed 8-pin female plug on the supply side and an 8(4+4) split male plug on the board side. The split design lets the same cable serve motherboards with either an 8-pin or a 4-pin CPU power header. Straight moulded housings keep the pin alignment firm during installation and removal.
Limits of the EPS extension
The 500 W ceiling and 18 AWG gauge restrict these leads to mainstream CPU power delivery; they are not rated for high-current GPU auxiliary connectors. The fixed 12-inch length adds reach but cannot span full-tower distances if the PSU sits far from the socket. The EPS pinout also prevents use on PCIe 8-pin graphics headers.

Questions about this item
Does the ATX CPU 8-pin EPS-12V female connector limit power delivery to the 500 W rating?
Yes — the 18 AWG UL1007 wires and connectors are rated for a maximum of 500 W, so the extension cannot safely carry more than that.
What clearance does the 12-inch cable need behind the motherboard tray?
The cable adds 12 inches of length; ensure your case has enough routing space behind the motherboard tray for the extra slack and the 8(4+4) male plug.
How do I install the extension without reversing the 4+4 pin halves?
Plug the EPS-12V female end into the PSU’s CPU 8-pin output, then align the 4+4 male keying with the motherboard socket — the split design only fits one way, so do not force the wrong half.
