How to diagnose a dead PS?
I have what I think is a dead power supply. There are no lights or any sign
of activity anymore. Normally there is a ASUS P5E MB LED on even when the PS if off. No response to the power button at all. Completely inert. No fans, no lights, no nothing. To make sure it's the PS, is there a voltage on one of the PS connectors that is ALWAYS present that I can check for to see if the PS is producing anything at all? I recently upgaded to all new parts so both the PS and MB are relatively new. Thanks. Bruce. |

You can start it with using a paperclip or something to short-circut a couple of the connectors: http://www.google.com/search?q=how+t...e7&rlz=1I7GGLJ -- Clas Mehus - "Den som har flest prylar när han dör vinner..." |

The LED on the MB that is normally on, even when the PSU is turned off, should be lit as long as the PSU is plugged in. It indicates that +5 V Standby voltage is present, which is necessary to turn the system on. Since the LED is out, that indicates the PSU is indeed bad. |

Not only is that LED usually on all the time, but the sound card that came with the P5E is usually lit up too. It's completely inert. No fans, no nothing. I measured the line voltage at the socket of the power cord and that looks fine. No sign of any activity at all, ao I've ordered a PSU replacement for it. This Corsair 620 PSU was only about 7 weeks old. Thanks. |

Pop a new fuse in and see if it ran. If the fuse blew again, time to buy a new supply. Sometimes a power spike popped the fuse and all would run OK after installing a new fuse. Now, the power supplies are so cheep, you couldn't get a technician to touch that power supply for what you can purchase a new one for. Also - what user doesn't need a larger wattage power supply for their computer. It's time to upgrade your system! William |

I've used Antec PSUs for years and the oldest one, about 6 years old, is still working fine. I'm not advocating Antec PSUs, just commenting that a good PSU should last for years. Good luck and you're welcome. |

I used to service IBM type equipment and I can't count the number of times a repair was nothing more than replacing a blown fuse or resetting a breaker. I don't know if these supplies have internal fuses they don't want us to know about, but it's frustrating than small line surges can take out the whole power supply instead of popping a fuse. But in this case I don't know if it was a line surge or a PS that went bad, or maybe both. Since it's only 7 weeks old, I suspect it was a defective PS. I did my homework and this power supply it came highly recommended in a power supply shootout article and the reviews on NewEgg are excellent. Sigh. Bruce. |

Been a long time since I used american sockets, all of the plugs you find in europe are fused, I seem to recall that nearly all nema plugs had no fuse.. The supply you spoke of doesnt have a fuse removal plug in the back of it, a lot of supply's dont. But the supply you have does have a lot of nitfy features so it's possible that something simple is dead (it has a temp sensor that can go, and the psu is dead).. Checking for the +5v as mentioned earlier is real important, as "typically speaking" most of the internal controls are ran from that +5v.. I would (for kicks) just use the same power plug on your monitor and make sure that all is well there.. for such a new supply it's not worth opening it as you should be able to get a warranty replacement. |
