Table 124. Remote Sense Requirements
Characteristic
Requirement
+3.3V remote sense input
impedance
200 (measure from +3.3V on P1 2x12 connector to +3.3V sense
on P20 1x5 signal connector)
+3.3V remote sense drop
200mV (remote sense must be able to regulate out 200mV drop
on the +3.3V and return path; from the 2x12 connector to the
remote sense points)
Max remote sense current draw
< 5mA

Note:
+12V current to PCIe slots may be supplied from four different connectors. 12V1 on P2, 12V2 on P3, 12V3 on
P1, and 12V3 on P12. P12 is reserved for board that needs 4 x GPU cards powered. P1 is the main 12V power
for PCIe slot; but additional 12V power can be connected to P2 and/or P3. The motherboard MUST NOT short
any of the 12V rails or connectors together.
13.4.2.6 Hard Drive 12V rail configuration options
The following table shows the hard drive configuration options using the defined power
connectors. In some cases additional converter or ‘Y’ cables are needed.
