Black 16-pin to 16-pin 12VHPWR power cable, 30 cm

Vszerda

Vszerda ATX 3.0 PCIe 5.0 12VHPWR 16-pin to 16-pin internal power cable 30cm

SKU CH-A076-YYBQY

Delivers up to 600 W through a single 30 cm 16-pin 12VHPWR cable for RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards

  • ATX 3.0 PCIe 5.0 12VHPWR cable delivers up to 600W to RTX 40-series GPUs
  • Single 16-pin to 16-pin connection powers RTX 4080 and 4090 cards directly from PSU
  • 30 cm 16 AWG length keeps cable routing tidy inside compact builds
  • Designed for 12+4 pin GPUs such as RTX 3090 Ti 4070 Ti 4080 4090
  • Compatible with modular PSUs featuring native 12VHPWR ports like GP-UD1000GM PG5

Direct GPU power delivery

This Vszerda cable connects an ATX 3.0 modular power supply directly to a 12+4-pin graphics card using a single 16-pin to 16-pin link. It is built for the PCIe 5.0 12VHPWR standard and supports cards such as the RTX 3090 Ti 4070 Ti 4080 4090 series. The 30 cm length keeps routing tidy inside the case. It is not compatible with the older 12-pin connector found on the RTX 3090 series.

Thermals noise and power handling

The 16 AWG conductors are rated to carry up to 600 W through the 12VHPWR interface. A direct single-cable path removes the need for daisy-chained adapters, reducing connection resistance and heat at the plug. No active cooling or fan is involved, so the cable adds no acoustic noise to the system. Power delivery remains stable within the PCI-SIG 12VHPWR H+ specification.

Ready-to-use simplicity

The cable ships as a complete modular assembly with 16-pin connectors on both ends, so no extra pins, combs or sleeving kits are required. Builder effort is limited to plugging one end into a compatible PSU port such as the GP-UD1000GM PG5 and the other into the graphics card. This single-cable approach eliminates adapter clutter and supports a clean internal layout.

Questions about this item

How do I install the 16-pin 12VHPWR cable and what is the common mistake?

Connect the 16-pin end from the PSU 12VHPWR port directly to the GPU 12+4-pin socket; the step people miss is fully seating both the 12-pin power and 4-pin signal rows until each latch clicks, otherwise the 600 W path can stay loose.

What maintenance or replacement will this 30 cm 16 AWG cable need later?

No scheduled maintenance; inspect the 16-pin connectors for discolouration or melted plastic after heavy 600 W loads and replace the cable if any pin shows heat damage.

What limit appears first when the cable runs at 600 W continuously?

The 16 AWG conductors reach their thermal ceiling before the 12VHPWR connector rating, so sustained 600 W draw will hit wire-temperature limits first.
