Wiring: 16 AWG braided copper * 80 degrees C * 300 V * WV-1/FT1 flame rated insulation
Length: 8 inch / 20 centimeters
Ends: Open wire to 6-pin male Molex PCI-E connector
Rating: ROHS / UL 1007 compliant
Each cable can reliably deliver 240 Watt/20 Amps @12 volts without any discoloration/burnout in 24-7 continuous use. We know it from practical experience with thousands of these cables over nearly two years. These are perfect for powering Bitcoin Antminer S9 or S7.
Please make sure the cable length (8 inch / 20 cm) is suitable for your setup. In our data center, we favor shorter cables to minimize heat loss and airflow obstacles.
We are not an electronics reseller, but an experienced large mine operator/engineer who shares the lessons learned. Here's the info on PCI-e cables:
- Consumer PCI-e cables (e.g. those coming with a PC ATX PSU) are not suitable for bitcoin mining. They have high likelihood of meltdown/burnout at the connector/boot joint.
- The weakest part of a PCI-e power cable is the pin boot at the connector. This is where heat, oxidation, and insulation damage build up. Our cables are custom-made by one of the leading power cabling manufacturers. The boot is properly crimped, and the connector is made of high grade heat-resistant materials.
- 16 AWG wire size is the "sweet spot" for this application. 14 AWG wiring is too thick for proper crimping to the pin boots. This poor joint can lead to local overheating, separation, and meltdown. Bigger is sometimes not better!
- Never use aluminum wiring, or wiring of 20+ AWG for bitcoin mining!
