Gateway Parts

Did my power supply damaged any other parts of my computer?

Guys i just bought a new custom computer 2 weeks ago. Today i went somewhere and left my desktop computer turned on. When i came back home my computer was totally shutdown. I pressed the power button but nothing happened not even a single led on my chases was turning on. My power supply is OKIA 500 Watt. I opened my power supply and checked wih meter if there is any 12 volts in its pins, certainly the result was negative. So i think power supply is blown up. Q1. Guys i am worried if it damaged my motherboard or other hardware before it blew up. Q2. If i replace the power supply is there any way to check all my hardware are working fine or not?

1. Ya, replace it and see if your stuff still works. It probably didn't hurt your components.
2. im sure it dident hurt any components or anything so u got nothing to worry bout just replace the PS and u will be good to go
3. If power supply is plugged the ONLY voltage available is on +5V standby rail. On the 24 pin ATX power connector, it is pin number 9 with the purple wire. If there are no signs of burned parts or burnt smell, here is a quick test for power supply: Disconnect all PSU connectors except one 4 pin connector that goes to a case fan. On the 20 or 24 pin ATX power connector, short the pin w/ GREEN wire to an adjacent pin w/ BLACK wire. You can use metal paper clip. Connect the PSU power cord and turn ON the PSU switch if there is one. If PSU is OK, PSU fan and case fan should immediately rotate. If nothing happens PSU is most likely dead or internal fuse is blown. If PSU turns out OK in the quick test, it is probably detecting a short in the PC, thus failing to turn ON. It is a standard safety feature. Quick test for hardware: Bare set up test= Mobo, processor with cooler, integrated or dedicated graphics (NO RAM, HDD, DVD and FDD) connected to PSU. This set up will NORMALLY give no display and the endless beep (RAM error since not installed yet). Power OFF, then add RAM. Bare set up should beep ONCE, display POST then be able to open BIOS menu. If bare set does not work, something (a short) is overloading the PSU thus activating the safety feature (overload protection). Mobo may be grounded to case or cpu heatsink (or its backplate if it is big) may be causing a short on mobo. Try running bare setup again but with mobo dismounted from case or not touching any metal part of case. If bare set up works, the short could be on one of the devices that connects to power supply or motherboard. Install them one at a time to find out which will cause the problem.
