Black 12+4 pin to 16 pin U shaped angled power adapter

Vszerda

Vszerda 12VHPWR ATX 3.0 PCIe 5.0 12+4 Pin to 16 Pin Down Angled 360° U-Shape Adapter

SKU CH-ZG1K-4XVQZ

A 12VHPWR ATX 3.0 PCIe 5.0 adapter converts a 12+4 pin source to a 16 pin GPU connector with a 360 degree U shaped down angle for tight clearances around RTX 4080 or 5090 cards

  • Fits tight GPU clearances with 360° U-shape down-angled design
  • Delivers up to 600W via PCI-SIG 12VHPWR H+ 12+4 pin connector
  • Compatible with ATX 3.0 and PCIe 5.0 power standards
  • Ready for RTX 4080 and 5090TI 16-pin graphics cards
  • Connects 12+4 pin PSU cables to 16 pin GPU socket securely

12VHPWR ATX 3.0 PCIe 5.0 adapter

This Vszerda adapter converts a standard 12+4 pin power supply output into the 16 pin 12VHPWR connector required by modern graphics cards. It supports the ATX 3.0 and PCIe 5.0 specifications for up to 600W delivery. The 360 degree U-shape angled design routes the cable downward to fit tight clearances around the GPU power port. It targets builders installing RTX 40 series or compatible AMD RDNA 3 cards where rear clearance is limited.

Sustained 600W delivery through PCI-SIG H+ terminals

The connector uses the PCI-SIG 12VHPWR H+ layout with twelve power pins and four side-band signal pins. This construction is rated for continuous 600W operation rather than only peak bursts. The modular adapter format adds no active components, so electrical performance depends on the source cable and PSU quality. It suits workloads that maintain high GPU power draw for extended periods.

Passive thermals with no added noise or power draw

As a passive metal-to-metal interconnect, the adapter generates no heat of its own and adds zero fan noise. Power loss is limited to the contact resistance of the gold-plated terminals under load. The downward U-shape routing can improve airflow around the GPU power socket compared to a straight backshell. It draws no auxiliary power and does not increase system wattage beyond the GPU demand.

Questions about this item

Does the 12VHPWR adapter generate noticeable heat when delivering 600W continuously?

The adapter is a passive cable with no active components, so it does not produce heat itself; any warmth comes from normal current flow through the 12+4 pin connector.

What power-supply connectors must I already have to use this 12+4 pin to 16 pin angled adapter?

You need a modular power supply that provides a 12+4 pin (12VHPWR) output cable; the adapter plugs into that cable and routes it toward the graphics card.

Will this down-angled 360° U-shape adapter fit alongside an older 8-pin PCIe power cable in a tight case?

The 360° rotating U-shape lets the 16-pin connector point downward, clearing space beside the card so an existing 8-pin cable can sit next to it without interference.
