Introduction (Cont’d)

High-end power supplies would use two separated auxiliary PCI Express power cables instead of using two connectors sharing the same cable (see Figure 4). Anyway, this power supply at least has these two connectors, as low-end power supplies usually don’t provide any auxiliary PCI Express power connector or, when they do, they only offer one connector.

This power supply uses two main cables, the main motherboard cable with a 20/24-pin connector and an ATX12V cable.

The gauge of all wires used by this power supply is 18 AWG, except the wires used by the auxiliary PCI Express power cable, which are thinner (20 AWG).

Only one aesthetic detail HEC could have worked on is regarding the plastic sleeving used by the cables. The sleeving doesn’t come from inside the power supply housing, so the wires are exposed when they come out of the power supply housing.

This power supply is really manufactured by HEC, as we could check by reading its UL number.

We decided to fully disassemble this power supply to take a look inside.
