What is the output voltage of the 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.
Can I plug a 5V into a 12V RGB header?
RGB devices are compatible with 12V headers that have 4-pins and are present in many motherboards nowadays. As 5V aRGB headers can only provide 5V of power, the lighting on the 12V RGB devices will most likely fail to show or may just be very faint.
What uses a DC IN 5V?
A 5V output is most commonly used when the end application needs powering via a USB connector, for example a mini/micro B or Type-C plug. Or, if space is at a premium, the DC cable and USB plug can be removed altogether and replaced with a female socket on the case like on phone chargers.
What uses a 12V DC power supply?
Devices that are often compatible with proprietary 12V DC adapters include: Cellphones. Laptop computers. GPS units.
What is DC and AC power supply?
Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. (Source: Unsplash)
What is the output voltage of a 12V DC power supply?
This is fixed, so instead of making a fixed output voltage their output is mostly proportional to the input AC voltage. For example, such a “12 V” DC supply might make 12 V at 110 VAC in, but then would make over 13 V at 120 VAC in.
Can the current rating of a power supply be higher than voltage?
In that sense, unlike with voltage, the current rating of a power supply must be at least what the device wants but there is no harm in it being higher. A 9 volt 5 amp supply is a superset of a 9 volt 2 amp supply, for example.
Do I need a DC or DC power supply for computing?
Most electronic circuits require a DC power supply. Chances are you have one at home already, and can use it for physical computing projects. The most common operating voltages for microcontrollers and digital processors are 5V and 3.3V. You can find power supplies in many voltages, but 5V and 12V are common.
What does it mean to connect power supplies in series?
Connecting Power Supplies in Series. The outputs of two or more power supplies can be easily connected in series to obtain a combined output with a higher voltage than provided by a readily available standard supply.
