Can you mix power supply cables?
There are two ends to a power supply cable: The device-side and the PSU-side. Mixing cables between power supplies can kill them or kill attached components.
How many cables connect to power supply?
Most PSU’s provide two cables; one with 4-pins and one with 8-pins. Obviously you only need to use one of these cables. It is also possible that your 8-pin cable can be split into two segments to provide backwards compatibility with cheaper motherboards.
Do power supply cables matter?
If you are referring to the 110 VAC power cord there is no problem as to which cord you use. However, the cables that connect from the PSU to the motherboard, devices, graphics card, etc. are not inter-changeable from one brand to another.
Why does USB 3.0 need a power cable?
Adoption of USB 3.0 could bring an end to interfaces that use serial ports like e-SATA, which, while fast, require an additional power cable. USB 3.0 sockets are designed to accept today’s plugs and cables, they’ll just operate at USB 2.0 speeds.
Are power cables the same?
Basically, if it’s just a cable (no power adapter) and it physically fits your computer, it’ll be just fine. Desktop computers (and many monitors) all use the same connector (IEC). Of course, different plugs are used in different countries, but electrically they are all the same. Again, these are standard cables.
What kind of connectors do I need for a power supply?
Power Supply Cables and Connectors. 1 P1 (PC Main / ATX connector) 2 P4 (EPS Connector) 3 PCI-E Connector (6-pin en 6+2 pin) 4 Molex (4 Pin Peripheral Connector) 5 SATA Connector.
Where are the extra 4 pins on the power supply cable?
The extra 4 pins on the cable just hang over the end of the motherboard connector. The 24 pin cable only fits into a 20 pin socket at one end so you can’t plug it in incorrectly. The extra 4 pins were added to the 24 pin version of the cable to provide one extra wire for ground, 3.3, 5, and 12 volts.
Are there different types of power supply cables?
Power Supply Cables and Connectors. There are a lot of different Power Supply connectors out there. Luckily they are designed in such a way that you cannot go wrong when installing them. The cable simply won’t fit in the connector slot when you try to connect the wrong header.
Why are there voltage lines on power supply connectors?
Some of the voltage lines on the connector may have smaller sense wires which allow the power supply to sense what voltage is actually seen by the motherboard. These are pretty common on the 3.3 volt line in pin 13 but are sometimes used for other voltages too.
