8-pin EPS to 6+2-pin PCIe cable

This 2 ft male-to-male cord converts an 8-pin EPS/ATX connector on a compatible PSU into a 6+2-pin PCIe plug for a graphics card. It is built for builders who need to route EPS power to a GPU without using an adapter. The braided sheath adds durability inside the case.

Compatibility limited to matching pinouts

The cable works with Corsair Type 3 and Type 4 units and other PSUs that share the same 8-pin pinout. It will not function with EVGA PSUs, the Corsair RM850X Shift series, or any unit whose 8-pin layout differs. Pin 4 on the PSU side is unused and pin 5 on the GPU side is double-wired for stable 12 V delivery.

Fixed length and single-purpose wiring

At 2 ft the reach suits typical mid-tower builds but offers no slack for extended routing or external enclosures. The conversion is one-way from EPS to PCIe; it cannot supply EPS power to a motherboard or drive. Buyers who need a longer run or a different connector arrangement must choose another cable.

Questions about this item

Will the braided shielding on this 2 ft Cable Matters 104078 cable degrade and need replacement over time?

The braided shielding is a durable outer sleeve that protects the internal wires; it does not wear out under normal use and requires no scheduled replacement.

What is the first limit reached when this EPS-to-PCIe cable runs a high-end GPU continuously?

The cable is rated for standard 12 V delivery through its 8-pin EPS and 6+2-pin PCIe connectors; sustained load is limited by your PSU’s 8-pin output capacity, not by the cable itself.

Does the braided Cable Matters 104078 cable add noticeable heat or noise inside the case during all-day operation?

The passive copper conductors and braided sleeve generate no audible noise and add negligible heat; any warmth comes from the GPU and PSU, not from the cable.
