One connector comes with 24 crimp terminals for power and 8 crimp terminals for signal / side band. The crimp terminals are twice as many as you need per connector, allowing you to make mistakes and only accept perfection.
The 12VHPWR connector features 12-pins for electrical power and 4-pins for side-band information.
When you order one (1) connector, you will also get twice the amount (24) of needed electrical power crimp terminals and twice the amount (8) of needed signal / side-band crimp terminals, allowing you to learn and practice crimping these smaller than usual (compared to ATX and common PCI-Express) crimp terminals.
Important knowledge about making custom cables with the new PCIe 5, 12VHPWR connector standard:
- Due to the smaller sizes in every aspect, pin to pin distance (pitch) of 3.00 mm (regular ATX / PCIe = 4.20 mm), a narrower wire insertion slot width of only 2.7 mm and smaller sized crimp terminals, you are much more limited with your choice of wire.
- The maximum outer diameter of your wire for the power crimp terminals can not exceed 2.7 mm, including the crimp terminal material on top of your wire insulation! The signal / side band crimp terminals are used with 23-AWG or 26-AWG wire (see gallery image for crimping technique tips).
- For the power wires, we recommend wire with a maximum outer diameter of 2.0 mm or less, for example a very high quality 17 AWG wire. A 16 AWG wire, as recommended in the PCIe 5 specs, will often result in imperfect crimps, which is a potential risk for your hardware. 18 AWG would be too far away from original specs in terms of electrical capacities and shouldn't be used if you don't want to risk your hardware.
- The gallery shows how to crimp such a wire with our CTX-3 crimping tool. Insert the empty crimp terminal into the smallest slot, close the handles only to the first stop. Strip the wire on a length between 2.5 to 3.0 mm. Insert the stripped wire correctly into the rear of the crimp terminal (as described in the gallery of the CTX-3 crimp tool). Close the handles of the crimping tool until there is good physical resistance, but not as far as the crimping tool can close! Use the "pre-opening technique" for the crimp tool, by using the little lever on the inner side of the bottom handle, as described in the CTX-3 product description text.
- Insert the crimped wire into the rear of the connector. As always: The top of the crimp terminal faces to the top of the connector. The top of the connector is on the side where the retention lock is.
- Removing / extracting the crimp terminals from the connector: Just pull with enough force in the direction of the wire. Before you re-insert the wire into the connector, make sure to re-bend the retention hooks on the terminal to its original position. Don't do this too often, as the fine structure of the hook might take damage.
