PCIe 5.0 12VHPWR Type B adapter

The RIITOP 12VHPWR adapter connects a PCIe 5.0 power cable to GeForce RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards. It uses a 12+4 pin female-to-male layout built to the ATX 3.0 specification. The pack contains two black adapters for builders running compatible GPUs.

180-degree angle for tight builds

The 180-degree bend routes the cable parallel to the card, adding only 7 mm of protrusion beyond the connector. This orientation preserves the original cable direction and reduces strain on the GPU power input. Builders with narrow side panels gain extra clearance, though the adapter will not fit if the GPU backplate extends more than 3 mm past the port.

Aluminium shell handles 600 W

A CNC-machined aluminium housing dissipates heat from the 16-pin interface while supporting up to 600 W of continuous power delivery. The metal shell adds durability without active cooling, so the adapter runs silently. Users must confirm their power supply cable is also rated for 600 W to match the adapter capacity.

Questions about this item

What is the maximum power draw the 12VHPWR adapter can sustain without overheating?

The adapter supports up to 600W continuous power delivery and uses a CNC-machined aluminium shell that acts as a heatsink to dissipate heat during sustained loads.

How much additional heat or noise does the aluminium shell add when the GPU runs all day?

The aluminium shell is passive and adds no fan noise; it simply spreads heat from the 12+4-pin connection, keeping the adapter cool during extended 600W operation.

Which existing power cable must I already have to use this Type B 180-degree adapter?

You need a native ATX 3.0 PCIe 5.0 12VHPWR 12+4-pin cable from your power supply rated for at least 600W; the adapter connects between that cable and the GPU.
