For this JPR1 power connector, you may use the 20-pin ATX power supply or 24-pin SSI power supply as you like. If you’d like to use the SSI power supply, please remove the sticker (covered the 11, 12, 23 and 24 pins, shown as the photo below) marked “SSI ONLY” on the JPR1 power connector to insert the SSI power supply in the proper orientation for correct alignment. If you’d like to use the ATX power supply, please just insert your power supply in the rest pins without removing the sticker.
