blown power supply

[mrblonde]

Good afternoon,
I'm learning here so I apperciate as much background as you are willing to give in your replies. I have a pc with (what I think is) a bad power supply. I have swapped cords and nothing happens when I turn it on. I'd like to know what a good tech would do at this point (other things to look at) and if it needs replacing, is there anything I need to know? (are power supplys standardized or are there variations, that sort of stuff.

Thank you to everyone for your time!!!

I think I would need a little more information.

What type of system is it and who makes it? You say nothing happens but do any power led's or fan's come on or does it just sit there and do nothing? Have you checked the circuit breakers where the computer is or tried another outlet? Also, if you have it plugged into a power strip or UPS you may want to plug it in directly to be sure those haven't failed. If you have made sure that the power supply is indeed getting power by elimintating all of these variables, then I would start looking at the power supply or other component within the PC. Justin

If absolutly nothing happens when you press the power switch. the first thing i will look for is
1: make sure switch is turned ON on the power supply if its ATX.

2: make sure power supply is getting juice.

3: make sure the power supplies cable is snug on the motherboard.

4:Test with new power supply.

the two kinds are ATX and AT.
if it's a fairly new computer it will be ATX
powersupplys are measured by wattage 230W or 250W or 300W or higher.

the standard nowadays is 250W or 300W but mainly 250.

if the fan motor on the power supply goes out, that can cause the power supply not to power up the pc.
if you have checked ALL power connector to the pc and you are sure the pc doesn't power up, then i would believe the fan motor failed to work. bring your pc to a local repair shop so that you can match up the fan motor, you may need to have the power supply replaced if the new fan motordoesn;t work either.

Aaaaargh!!!!

I just replaced the power supply. I've got all the connections snug. Nothing, no fan, no LED, nothing. I'm going to double check all the connections here, but what now?
