SURE A+
✔✔What is a M.2. Interface - ✔✔An adapter card inserted and screwed in to the
motherboard.
comes in many lengths (42 mm, 60 mm, 80 mm, or 110 mm)
Does not need a cable (powered through bus )
✔✔what is an eSATA - ✔✔External SATA Interface
must use an eSATA cable to connect to an eSATA port.
power is not supplied over cable
✔✔True or False: The power supply unit (PSU) delivers direct current (DC) low voltage
power to the PC components - ✔✔true
✔✔Describe a PSU - ✔✔Power supply unit
, converts AC power to DC volts
most have duel voltage auto switch to correct voltage and some have manual switch
fixed voltage psu only accept high line low line voltage
✔✔what is the low line range - ✔✔100-127 VAC
✔✔what is the high line range - ✔✔220-240 VAC
✔✔What is power? - ✔✔rate at which things generate or use energy
measured in watts
calculated V*I (volts x current)
✔✔Define wattage ratting - ✔✔Measure of how much power can be supplied by a PSU
measurement of the power supply unit's output capability

✔✔what is the wattage rating for a Gaming PC - ✔✔500W or better
✔✔what does a power connector do - ✔✔supply DC voltage to the motherboard and
devices at 3.3 VDC, 5 VDC, and 12 VDC.
✔✔What does the voltage regulator do? - ✔✔correct the voltage supplied from the PSU
(to the voltage required by the component)
✔✔What is the motherboards power port referred to as - ✔✔P1 connector
✔✔describe the P1 connector - ✔✔a 20 pin connection (2x10)
black wires for ground
yellow for +12v
