i guess u r a professional..as u r handling power supplies..
ur point of view has always a priority..

no 'the led on the power supply be bright at first and then go dim after connecting the power cord'..this happens when there's no/incorrect oscillation/frequency due to push-pull failure, incorrect wattage output etc.
well, itz likely to b the power supply causing it..!!..

however, check the following:

1) the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg & grey~sb); -12v (blue); -5v(white); +3.3v(orange)..
the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..

2) if itz not the smps, then it must b ur main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above 1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector....

3) remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

4) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

5) see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..

6) check cmos battery (above +3v)..

..plz give higher priority to step2 (as listed above) CAREFULLY..

always better to seek advise from ur system admin/vendor....

Smps part no 243890-001 is dead and i want to replace


Dear skytechcompu,

Power Supplies can be expensive!
I found your part for $146.00 @ http://www.partstore.com/Part/Hewlett+Packard/Compaq/243890001/Refurbished.aspx

You could order FixYa's Guaranteed Solution and try to fix the power supply yourself for less!

Hope this is Helpful!

450W ATX SMPS of Intex


sir all smps can be reapired using indian jugar technique. first of all see twi diods under the burnt transistors check them they are short then check the capacitors if they are not leaky or pregnant then see bridge reactifier change all that looks short or open then replace all and the transistors with 13007 transistors(jugad) be careful that 13007 must be isolated from heat sink that means metal part must be fixed to them but not short to them . replace the fuse with 2 ampere fuse (for safety) ..... have fun

hi there, you should be able to purchase a 400 watt ATX power supply from any pc part retailer, even better, buy it off the net, its usually cheaper. 99% of supplys be they the old AT (mostly obsolete now) or ATX will fit like a glove. Best of luck and I hope this helps...

HOW DO U KNOW THE CAPACITY OF AN COMPUTER SMPS (unbranded)


Maximum output of any smps is not based solely on the type of power switching transistors used. One of the parameters which will be crucial is the Ic (Max collector current rating). But this by itself isn't the lone determining factor either.

Other design factors which will come into play are the switching transformer, its size and windings. A smaller transformer and smaller wire gauge windings will generally mean lower max power output.

Max power output measurements probably require a set of load resistors, volt and amp meters, monitoring the 3.3, 5, 12 volt lines.

I'm not an engineer, but have had numerous computer power supplies apart, repairing some, junking some. Quality of construction or lack thereof is generally obvious. PC Power and Cooling probably builds high quality units. There are plenty of cheap, low cost power supplies which frequently die after a year or two, sometimes taking a motherboard down with it.
