Power Supply Considerations<br />
● Power connectors<br />
<strong>D2568</strong> is powered by a split plane PSU with six +12V-rails and 1000W continuous power. One rail is<br />
for each processor, one for systemboard and three for peripherals (e.g. HHDs, add. 6-pin graphics<br />
connector). There are three power connectors on this motherboard as listed below.<br />

By following SSI EEB v3.51 specifications, <strong>D2568</strong> is designed with two separate voltage<br />
regulator circuits to provide the power for both onboard processors in separate power rail.<br />
Using a power supply with a combined CPU power plane from the CPU power connector is not<br />
allowed and may cause the system to fail to power up or damage to the power supply.<br />
