A technician is required to replace a faulty power supply in a desktop PC. The PC motherboard has a 24-pin ATX socket but the only available replacement power supply is one with a 20-pin connector. Delivery of new power supplies with 24-pin connectors is not expected until the next day, but the user requires the PC to be operational as soon as possible. What can the technician do in these circumstances?
- The technician can install the power supply and insert the 20-pin connector into the 24-pin socket on the motherboard.
- Power supplies with 20-pin connectors are not compatible with motherboards with 24-pin sockets, so the technician can do nothing until the new power supplies arrive.
- The technician can use a 20-pin-to-24-pin adaptor to connect the power supply to the motherboard.
- The technician can recover the 24-pin connector from the faulty power supply and attach it to the replacement power supply for connection to the motherboard.
Explanation: 20-pin power supply connectors are compatible with the 24-pin socket on the motherboard, so the replacement power supply can be used temporarily if necessary. A power supply 20-pin-to-24-pin adaptor does not exist. Power supplies are not considered to be field repairable, so it is not recommended that the technician attempt to modify the power supply connections, although this is not required in this situation.
