Depends, check to see if you have the power switch pin-outs from the case to the motherboard properly connected, they might be reversed.

Smps colour


Okay; first off an SMPS is any number of power supplies used for electronics. So this is a very vague question. In a computer power supply to an IBM or PowerPC based motherboard (the later is now obsolete and no longer in use for most new computers) there is no one power supply "wire". Most video cards are powered via PCI port through the motherboard power supply connection.

Some very high power high end video cards and some SLI/Bridged cards require their own power source and this is usually a 12 volt rail much like the ones used for SATA power supply.

In a monitor, each make and model can be different depending on who supplied the power supply. The internal power cords can come in different colors. Though the standards are black white blue and green and red. Most displays don't use colored cords for connecting to the main board of the display. They use a 8 or 10 pin ribbon. Most of the colored wires are linking the main inducer to the LED back light.

If we're talking about the internal workings of an SMPS (Switch Mode Power Supply) there is no "display" wire. SMPS internal wiring is all about controlling and routing power to the different rails (that is the different power connectors). Never open an SMPS case, especially if it's plugged in. Switch-mode power supplies have capacitors that can provide a rather nasty charge, and several inducers that can hold a charge well after the power supply has been unplugged. Never service an SMPS on your own, always seek a professional when attempting to fix an SMPS. Though, for the most part, fixing a burnt out power supply is a waste of time, it'd be best just to buy a new one and recycle the dead one.

Mercury PI865D7 Motherboard system is won't turn on. I Checked SMPS and RAM. it's also a good then what's the problem for this....And Coming high pitched Bee Sound Repeatedly.....


Hello the manual can be downloaded here:

http://www.mercury-pc.com/downloads_list.php?productid=684

Check the ram modules, and the graphic card.

How many beeps comes, when you start the pc ??

Here is a list of beep codes:

http://www.computerhope.com/beep.htm

One long beep is a ram module failing.
Try insert one module, and reboot.
The problem could also be, the power supply.

Here is a fault finder guide:

Smps transistors failed


It is difficult (or impossible) to tell exactly what caused the transistors to go bad. Sometimes they just fail because they were a little weak, or other parts went bad first and caused the transistors to be damaged. Parts get weaker and values change over time and with use, and failures can happen. The UPS can't stop damage to the power supply if some part inside the supply goes bad, but it is still good to have one. New 450 to 500 watt power supplies can be purchased for $30 to $50 (or more).
