For single 12V operation both connector 24pin and 4pin are required!
24pin ATX connector :
1. Pin8, 14, 16(NC) must NOT be used in single 12V mode
2. Pin9, 10 , 11 are responsible for the operating mode
3. Pin9: Leave open or connect to 12V. Don’t connect to GND
All four +12V
in
pins must be connected to the +12V supply source.
Both GND pins (4-pin conn.) & two GND pins (24-pin connector) must be connected to the
supply source.
Important Note (Single 12V mode):
The “output” pins (3.3V
out
, 5V
out
, 12V
out
) provide power for drives or extra devices.
Maximum “output” power ratings:
+3.3V


: max. 4A = combined output current of 3.3V PCIe x16 and 3.3V

pins (1, 2, 12, 13)

: max. 6A depends on output power of single 12V PSU! (12V

If the mainboard is off no output voltages are available on the 24 pin ATX connec

Note: Each single pin of both connectors is capable of max. 8A!
