HEC WinPower 480 W Power Supply

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 3) and also they would use a separated cable for EPS12V connector instead of using an adapter (see Figure 4).

Figure 3: The two auxiliary PCI Express power connectors share the same cable.

Figure 4: EPS12V connector is provided through an adapter.

This power supply uses two main cables, the main motherboard cable with a 20/24-pin connector and an ATX12V cable. Like we explained, this power supply provides an EPS12V connector through an adapter.

The gauge of the wires used on the main motherboard cable is 18 AWG, but all other wires are 20 AWG, which is thinner.

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.
