What is the voltage for Molex cable?

Standard 4-pin Molex connectors coming from a PSU supply ~12v on the yellow wire, and ~5v on the red wire.

How many volts is a 4 pin Molex connector?

12 volt
It’s not a technically useful term because the 4 pin 12 volt cable is also a 4 pin Molex cable (Molex makes lots of connectors) but “4 pin Molex” is commonly used to refer to peripheral cables anyway.

How much power does a 4 pin Molex put out?

The Molex designed 4 pin connector itself can handle 156 watts.

What is the power of Molex connector?

The 1.57 mm pin can carry 5 A of current, while the 2.36 mm can carry 8.5 A. Because the pins have a large contact surface area and fit tightly, these connectors are typically used for power.

What are the 4 output voltages of a power supply?

Standard output voltages The positive output voltages produced by a power supply unit are +3.3V, +5V and +12V. Negative voltages of -5V and -12V are also provided, together with a +5V standby voltage.

How many volts is a 4 pin power supply?

As a result the PSU delivers most of its wattage at 5 volts. There are three or four lines dedicated to the 5 volt rail. The other main rail is 12 volts….Original PC main power cables.

Pin number Wire color Description
4 blue -12 volts
5 black ground
6 black ground

Can you power a GPU with Molex?

And even beyond that, there’s the issue that using Molex->PCI-e adapters is far from ideal: a single Molex plug carries a single +12v wire, with a rated maximum capacity of 8.5a. In theory, this works okay for a 2xMolex->PCI-e 6-pin adapter, but when you get to the 8-pin plugs, this can start to strain its capacity.

What are the voltages of a SATA connector?

The new SATA power connector contains many more pins for several reasons: 3.3 V is supplied along with the traditional 5 V and 12 V supplies. To reduce impedance and increase current capability, each voltage is supplied by three pins in parallel, though one pin in each group is intended for precharging.

How much power can a Molex cable carry?

The ATX standard for SATA or Molex connections is rated for 54 watts. Each SATA/Molex connector provides three 12v pins at 1.5 amps each, for a total of 4.5 amps. 12 volts, times 4.5 amps, equals 54 watts able to be provided by a SATA/Molex connector.

What three voltages are commonly provided by the power supply?

How PC Power Supplies Work

  • 3.3 volts.
  • 5 volts.
  • 12 volts.
