ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for an ATX power supply. The plugs from the power supply are

designed to fit these connectors in only one orientation. Find the proper orientation and

push down firmly until the connectors completely fit.

• For a fully configured system, we recommend that you use a power supply unit (PSU)

that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum

power of 400 W.

• Do not forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not

boot.

• We recommend that you use a PSU with a higher power output when configuring a

system with more power-consuming devices or when you intend to install additional

devices. The system may become unstable or may not boot up if the power is

inadequate.

LPT connector (26-1 pin LPT)

The LPT (Line Printing Terminal) connector supports devices such as a printer. LPT is

standardized as IEEE 1284, which is the parallel port interface on IBM PC-compatible

computers.
