2.11 Installing the Power Supply
The S8238 motherboard requires a proprietary power supply. This product does
not follow a standard ATX, ATX12v or EPS12v power connector specification.
Only the PW1 20-pin connector is required to properly power the S8238.

TYAN recommends the use of YR190 B8238-X2 Transport System
for a complete barebones solution that includes chassis, power
supply and motherboard solution. If a separate design is
required, the 20-pin proprietary connector design would need to
follow the outline below. TYAN would also suggest a minimum of
450w per node minimum.
