1.8 - Connection Types And Their Voltages

Question 1

SATA Power Connector

Answer 1

15 pins

+3.3, +5, and +12 V wires
+3.3 rarely used

Question 2

Molex Connector

Answer 2

4-pin power connector used for many devices in computer case (i.e. Hard drives, floppy drives, peripherals, etc)

+12 and +5 V

Question 3

4-pin ATX power connector

Answer 3

ATX12C Advanced Technology Extended Motherboard Connector

+12 V to ATX12 motherboards

May be labeled ATXV12, P4 or CPU

Question 4

4+4 connector

Answer 4

8-pin EPS +12 V power (or cable)

Can combine with ATX +12V 4 pin to create 8-pin EPS +12 V power

Made to give +12V power to multiple CPUs (most on servers) p

Question 5

6-pin PCIe power connector

Answer 5

75 watts providing +12V

Commonly seen in high-power components

Can combine with 2 pin modular connector to create 8-pin PCIe connector

Question 6

8-pin PCIe power connector

Answer 6

150 watts providing +12V

Commonly seen in high-power components

Can combine with 2 pin modular connector to create 8-pin PCIe connector

Question 7

Formula for Watts

Answer 7

Volts * Amps = Watts

Question 8

Ampere

Answer 8

Amp - rate of electron flow pat a point in 1 second

e.g. Larger hose = more water (amps)

Question 9

Voltage

Answer 9

(Volt, V) - electrical “pressure” pushing the electrons

e.g. Turn faucet up higher will make more pressure in hoes = more voltage
