Fasgear FG-16PM03 12VHPWR GPU cable

The Fasgear FG-16PM03 is a 70cm PCIe 5.0 power cable built for graphics cards using the 12VHPWR 12+4 pin connector. It links RTX 4090, 4080, 4070 Ti, 4070 Super, 3090 Ti and 5070 Ti cards to fully modular Corsair, Great Wall or Thermal-take PSUs via two 8pin (4+4) male plugs. This cable is not compatible with GPUs that use 12pin or 8pin power connectors such as standard RTX 3090 or 8pin RTX 4070 models.

Thermals noise and power delivery

Rated for 600W at 12V and 50A, the 16 AWG tinned copper conductors handle high current loads without excessive heat buildup under normal gaming or compute workloads. The nylon braided jacket adds abrasion resistance while keeping the cable flexible for routing. Because the cable draws power from two separate PSU 8pin ports, load is balanced across both connections, reducing stress on individual pins and keeping connector temperatures within safe limits during sustained operation.

Bundled cable combs and pinout verification

Four cable combs are included to align the sleeved wires neatly inside the case, improving airflow and making the build look clean. The supplied pinout diagram shows Pin 1 to 3 as +12V and Pin 4 to 8 as GND on the PSU side; buyers must confirm their modular PSU matches this layout before connecting. Using the cable with a mismatched pinout or with fewer than two occupied 8pin ports can cause system damage, so verification is essential before powering on.

Questions about this item

How do I install the FG-16PM03 cable, and what step do people often get wrong?

Connect both 8-pin (4+4) plugs into free CPU ports on a Corsair, Great Wall or Thermal-take fully modular PSU, then attach the 16-pin (12+4) end to the GPU. The common mistake is using only one 8-pin connector, which can damage the system.

What maintenance or replacement will this cable need later?

The nylon-braided 16 AWG tinned-copper wires are rated for 600 W continuous load. Inspect the connectors periodically for discoloration or loose pins; replace the cable if any melting or corrosion appears.

What limit appears first under sustained heavy use?

The cable is specified for 50 A at 12 V, giving a 600 W ceiling. Exceeding that draw will hit the thermal and current limit of the 16 AWG conductors before any other constraint.
