The pc energy provide is a tool that gives energy for all gadgets on the pc to function. Gives voltage for the cpu vcore supply, supplies chipsets, pc parts, video playing cards, and provides. voltage 5v and 12v for arduous drive, DVD drive. If the ability provide doesn’t work, different gadgets won’t work or function intermittently.
Energy provide English title is energy provide unit (abbreviated PSU) referred to as energy provide unit. ATX energy provides have manufacturers resembling Acbel, Arrow, cooler grasp, SD…With capacities like 400w, 450w, 650w…However usually these capacities usually are not as said on the label. The ability provide consists of 24 pin and 20 pin sorts (pins) and 4-pin or 6-pin pins to provide voltage to the cpu, and has 6-pin pins to provide voltage to the graphics card with totally different colours resembling: yellow pins = 12v , crimson pin = 5v, orange pin = 3v3, inexperienced leg to set off the black pin is the mass pin, the purple pin is the 5v pre-source, the brown (grey) pin is the nice pw (sign okay).
To examine the supply is working or not. You plug within the energy, use a copper wire, or a lead wire to attach the inexperienced (ps-on) and floor (com, black) pins, often pins 14 and 16. If the fan rotates then the supply continues to be good (to not point out different illnesses, there’s a fan nonetheless spinning however the machine doesn’t activate), this fashion is used to rule out the case of turning on the pc and the fan doesn’t spin. There are various good sources resembling Acbel with a safety circuit when shorting these two pins, the fan doesn’t rotate (the supply is nice) for the fan to rotate, it’s mandatory to connect a further peripheral machine resembling a tough drive, cd drive, dvd.
Frequent illnesses within the energy provide embody:
The supply of voltage drop often known as edema, dry capacitor: This illness usually causes the machine to flicker, resembling booting with no image, the machine beginning however not recognizing the arduous drive, the machine working for some time, restarting or shutting itself down. , in these instances ought to examine the ability provide first. This illness solely must be changed.
Energy on the fan doesn’t spin, or rotates just a few occasions after which turns off: On this case, there are a lot of causes. Have to be acquainted with electronics to have the ability to repair it. As a result of throughout the scope of the article, I solely introduce illnesses of the supply solely. This illness is often brought on by a 5v voltage loss on the blue pin that makes the supply unable to set off, the 5v stb voltage loss, the oscillation ic dies, the safety ic , mosfet quick, fuse damaged…
Energy supply fan rotates however doesn’t flip up : This illness is often brought on by the lack of good voltage pw on the brown pin, lifeless ic oscillator or safety ic.
When checking that the machine can’t energy on, run it for some time after which flip it off, or it may well energy on however the machine doesn’t present up, it is best to examine the ability provide first. If you wish to study extra about widespread illnesses within the energy provide and the best way to repair it, you’ll be able to go to hocnghetructuyen.vn for reference.
