Power Supply

This adapter power is supplied by +12V from a 6-pin type PCIe auxiliary power supply as shown in Figure 5.

The power switch controls the power supply to the adapter and the installed SSD. The power-on status can

be checked with the LED next to the power switch.

The +12V power supply is used to generate a +3.3V power supply with a DC/DC converter inside the

adapter, which has a maximum supply capacity of 20A. The current consumption of the adapter itself is as low

as 100mA, so even when four M.2 SSDs are installed, the power supply can supply approximately 5A per

SSD.

Connector for Cooling Fan

When continuously operating the latest high-speed SSDs, it is necessary to cool the heated SSDs using a

heat sink with a fan, etc. This adapter is equipped with four fan connectors that supply +12V for cooling fans

at the positions shown in Figure 6. The pin assignment of each connector is as follows.
