COMeap Mini 12-Pin GPU Power Adapter (2-Pack)

COMeap 2-pack 12-pin GPU power adapter converts two PCIe 8-pin female connectors into a single Mini 12-pin male plug to power compatible NVIDIA GeForce RTX 30-series cards.

This pair of short, flexible adapter cables (9.5 inches / 24 cm each) is made to bridge the gap between many standard power supplies and modern graphics cards that use the compact Mini 12-pin power inlet. If your PSU lacks a native Mini 12-pin lead but has two available PCIe 8-pin outputs, these adapters let you connect without rewiring the supply or buying a new PSU. They are sold as a set of two identical cables and include a small adhesive strap for cable management.

Will these adapters work with my power supply and GPU?

They are designed for use with non-modular and semi-modular PSUs that already provide two PCIe 8-pin power outputs. These adapters are intended only for graphics cards that accept the Mini 12-pin form factor, such as many models in the NVIDIA GeForce RTX 30 series.

• Connects two PCIe 8-pin female plugs from the PSU to one Mini 12-pin GPU inlet.
• Compatible with RTX 3090 / 3080 / 3070 / 3060 / 3050 models that use mini 12-pin.
• Not compatible with fully modular PSUs that do not have fixed PCIe 8-pin cables.
• Do not use on motherboard CPU or other non-GPU connectors — risk of damage.

How durable and safe are these 12-pin adapters?

Each cable uses 18 AWG tin-coated copper conductors and standard insulation to handle typical GPU power demands when used correctly. The connectors are molded for a secure fit and the included adhesive tape helps keep the cables routed cleanly to reduce strain on the plug faces.

• Wire spec: 1007-18AWG tin-coated copper for stable conductivity.
• Length: 9.5 inches (24 cm) — short enough for tidy routing in most cases.
• Connector housings molded to minimize wobble and maintain contact.
• Includes adhesive cable strap for fast, neat installation.

What should I avoid when using these adapters?

These cables are intended solely for GPU Mini 12-pin power inputs. Never connect them to CPU or motherboard power sockets, and avoid using them with power supplies that don’t provide two separate PCIe 8-pin outputs. Incorrect use can damage components and void warranties.

• Do not plug into motherboard or CPU power headers — may burn or fail.
• Not suitable for fully modular PSUs without fixed PCIe 8-pin leads.
• Ensure both 8-pin connections are seated and the PSU can supply required power.
• Check GPU manufacturer guidance for recommended cabling and amperage.

Who is this for? These COMeap adapters are aimed at PC builders and upgraders who have an RTX 30-series GPU with a Mini 12-pin inlet but whose current power supply lacks a native Mini 12-pin cable. They suit users who prefer a tidy, short cable route inside mid-tower and full-tower cases and who have PSUs that offer two PCIe 8-pin outputs. If you own a fully modular PSU without appropriate fixed PCIe leads, or if you’re unsure about power requirements, consult your PSU and GPU manuals or a qualified technician before installing.
