JETWAY G03-TI70MG-F User Manual page 10

** We recommend that you use an ATX 12V Specification 2.0-compliant power
supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin
and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the
20-pin power plug can provide at least 15A on +12V and the power supply unit
has a minimum power rating of 350W. The system may become unstable or may
not boot up if the power is inadequate.
** If you are using a 20-pin power plug, please refer to Figure1 for power supply
connection. Power plug form power supply and power connectors from motherboard
both adopt key design to avoid mistake installation. You can insert the power plug into
the connector with ease only in the right direction. If the direction is wrong it is hard to
fit in and if you make the connection by force if is possible.
