Remarks -This PSU comes with a 24pin (20+4) connector for the board (multicolored wires) and a special 20pin connector for the drives (yellow, red & black wire). Make sure they are connected correctly as they have the same shape but different pinout. -Some QNAP systems require a 24pin & 12pin connectors. Our PSU Comes with a 24pin & 20pin connectors. Your machine should already include a "20pin-to-12pin adapter". Please keep this adapter and attach it to the 20pin connector of our PSU. -Some QNAP systems may require an additional 8pin connector (4 yellow and 4 black wires). This connector is supplied as standard with our PSU. -If you require a similar QNAP PSU but less wide (80mm) please check our website. -A cable with 2 small connectors (4 wires: black, orange, brown, red) may be tied up with your original QNAP PSU cables. This cable is actually independant and is not part of the PSU. It does not come with our replacement PSU. Cut the cable ties, detach it from your old QNAP PSU and reconnect it in your QNAP box. The connector with the Black, Brown, Red & Orange wires goes to the boards on a 4pin socket that may be labeled "panel" or "LCM" and the other end with Black, Orange, Brown & Red wires goes to the front LCD display.
