Questions & Answers

Q1: Why our cable can carry a maximum of 600W power?

A1: Our cable uses High Conductivity Copper Terminals, which can carry current up to 10-12A. 16AWG copper wire can also carry 12A current. Theoretically, there are 3 power supply circuits within an 8pin. 10A*12V*3=360W, that means, a single 8pin can carry a maximum of 360W power. The amount of power output depends on the capacity of the power supply. In theory, a single 8pin port of the power supply can output about 300W.

Q2: Will it affect using when the cable has one empty pin?

A2: No, it is not affect using because the one empty is connected to the GND wire with the function of overcurrent protection.

Q3: What PSUs are compatible with it?

A3: It is compatible with for most modular power supplies, which requires 3 unoccupied 8pin PCIe/CPU ports at least. Compatible with ASUS, EVGA, Seasonic, Corsair, Thermal-take, Great Wall, NZXT, MSI, etc.
