Having problems with your Dell Dimension C521 PC Desktop ?

DELL HIT BY LIGHTNING, WILL NOT TURN ON. HOOKED UP ANOTHER POWER SUPPLY TO IT, BUT ONLY AN EMBER LIGHT CAME ONE. BUT IT WAS A 20 PIN, AND MY DELL IS A 24 PIN.


Answers :

You can buy and adapter that will turn a 20 pin connector to a 24 pin connector to test the board with the other powersupply(i would use it just to test). Most powersupplies that I have inspected do not have a fuse in them. Don't buy a powersupply from the manufacturer they charge too much. There are very cheap power supplies available online for sub $30 dollar prices. Most of the time when an electrical surge happens the PS takes most of the hit and burns up.
You'll need to match the power supply, if it's 24-pin, you need to use a replacement 24-pin power supply, otherwise you will not be able to power up the system. I recommend checking dell's site for a replacement, or tigerdirect for a compatible aftermarket power supply. They're relatively inexpensive.
