At work we have a voltage meter we can hook it up to - or if we suspect its bad we have a spare one we know works that we put in to try.

Turn on the computer nothing happen then smell burning from the power supply! turned off right away.


That power supply is probably dead. try your motherboard witha known-to-be-good power supply to determine if your system has survived. IN my experience the failrate for antec sp450 watt psu is close to 40% over 4 years (300 pc:s at university), so there is a high probability that your psu is unrecoverable.

If your psu is missing 5VSB it is defective and should be returned to manufacturer or retailer if within warranty period. See testing psu articles also.

Cooling fan for antec power supply pp 303xp does not come on when computer is switched on. Is this a replaceable item or do I have to buy a new power supply?


I THINK I REMEMBER reading that Antec had introduced a feature on some of their psu s where essentially the fan(s) were thermally controlled - if the psu was not working very hard it remained cool and the fan remained off but as the psu got warm with additional load it gradually increased fan speed. Perhaps this the issue you are seeing and nothing is wrong ?
PSU's are generally difficult to open and contain few accessible parts. some you can actually change the fan. I don't know about yours though.

The fan turns on and off for the SL350


you might have a faulty PSU power supply unit or a faulty power point or lead
test the power point first by trying another electrical device then test the lead if these fail you will have to test the PSU using a multimeter making sure your psu is getting the correct amount of voltage and wattage
hope this helps

I agree with you about the power supply being faulty. Unfortunately FixYa is not affiliated with Antec nor sells or service any computer components.
You need to contact the supplier who sold you the power supply or contact Antec.

Ive antec pc case with twin 550 psu's there are five sockets


The Power supply willhave to pin #16 connected to pin #15 for an ATX power connector. It would bebest to purchase a Power Supply Tester for about $20.00, which will test allvoltages with a load and give you a go or no go signal. If you want to use ameter to check voltages, here is a link for the pin outs.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
