Can you put ATX PSU in micro ATX?
1 Answer. YES. A micro-atx motherboard will work fine with an ATX case and power supply. Atx cases normaly included the standoff mounts for smaller mirco-atx motherboards.
Can I use a 5V power supply on a 12v?
In one word — no–. The battery won’t charge on 5V and it may even try to feed back into the 5V charger if for example one of the rectifier diodes is blown. Nice one Core.
How can I increase my power supply voltage?
The one closest to the fan is the 5v. You turn it clockwise to raise the voltage. The other pot is located underneath the wire bundle near the back of the psu. That is the 3.3v and you turn it counterclockwise to raise the voltage.
How do I increase the voltage on my power supply?
Two or more power supplies can be connected to supply higher voltages or current. The simplest method to create higher voltage is to connect the power supplies in series, set each supply to output the same voltage and each supply should have the same current limit.
Can a ATX PSU fit in a Matx case?
azaran : Short answer: Yes.
Do you need a bench or ATX power supply?
Everyone sometimes needs an adjustable power supply. Bench power supplies are expensive and therefore we usually use what’s available. The most well known power supplies of a high current low voltage are AT or ATX supplies from computers.
How to modify an AT / ATX computer power supply to a 3-15v?
Therefore, I present a simple modification of an AT or ATX PC power supply to an adjustable bench power supply of 3 – 15V with a proper regulation and an output current corresponding to the original 12V output. The voltage feedback is connected to pin 1 of TL494 control chip (or its equivalent KA7500, KIA494, DBL494 …).
How does feedback work on an ATX power supply?
There’s usually UC3843 and is on the primary side. Feedback is introduced via optocouplers. Voltage is sensed by TL431 (GL431, AZ431 – letters may vary). This circuit also has a 2.5V reference, so the principle is similar. From the reference pin (R) resistors go again to the ground, +5V and +12V.
How to create a variable output in ATX bench?
The only thing left to do is add the variable output and make a case for it! For the variable output, we need some characteristics of the LM317 voltage regulator first. The output voltage is defined by this formula: Vout = 1.25* (1+ (R2/R1)). The resistors are indicated on the schematic.
