A 180-degree angled 12VHPWR adapter with 16-pin male-to-female connectors that reduces cable strain and improves airflow in tight builds
This 16 pin PCIe 5.0 male to female U-turn connector redirects the power cable at a right angle. It suits builders fitting high-end graphics cards into compact cases where straight connectors press against side panels. The F-type orientation matches specific GPU port layouts shown in the product images.
An aluminium housing with an integrated thermal pad draws heat away from the connector terminals during normal operation. This passive dissipation reduces local temperature buildup without adding active cooling noise. The rigid shell also supports the cable weight, preventing the port from sagging over time.
The fixed 180 degree bend eliminates sharp bends at the GPU power socket, protecting both the cable and the card's input pins from fatigue. Installation requires no tools; the adapter seats directly between the PSU lead and the graphics card. Buyers must verify the F connector variant matches their card's port orientation before ordering.

No published specifications for this item yet.
Align the 16 pin male plug with the GPU socket, seat it fully until the latch clicks, then route the existing cable into the female side; the common mistake is not confirming the card slot direction matches the F or Z connector variant before purchase.
No scheduled maintenance is required; inspect the 12+4 pin contacts and the aluminum shell thermal pad during routine PC cleaning and replace the adapter only if you see discoloration, melting or physical damage.
The 180 degree U turn design reduces cable bending stress, so the first limit is typically the thermal capacity of the aluminum shell and pad to dissipate heat from the 16 pin connection during prolonged high current draw.
