Power Supply Failure. Help!

FairLady, on Monday 3 March 2008 à 08:31:36

Hi, there

First of all, I have to say I’m kind of a newbie…

I recently built a new computer with the following specs:

Case: Antec 900
Processor: Intel QX9650
Motherboard: Intel DX38BT
Memory: Corsair twin3x2048-1333C9G DDR3
HDD: Samsung HD501LJ 500GB
Power Supply: Silverstone ST75F 750W
DVD: Liteon LH-20AIL
Video Card: Leadtek Winfax GeForce PX 8800 GTS 512 MB

After setting the computer up and turning it on, it worked fine.. for all of 5 minutes before the power supply packed it in!

In other words when supplying power only the green light on MB came on. I have no idea why the power supply quit..

If you have an idea or know what went wrong I would really appreciate your help in this matter. My suspicion is that maybe the power supply could not handle the load, but once again I am not sure at all.

Thanks in advance.

Yeah, it's propably a problem with the cables... See if all are well-connected.... I don't really think you should change the power supply because you bought all your stuff together, like a kit.. So, look in the manuals if all these things are at their right place!

I'm answering your question with other questions... ;-)

What's the brand of your PSU?
What's the max wattage?
And what amps are supplied on each (should it have more than one) 12v rail and 5v rail?
What tells you the PSU quit? Did it go 'pop' ?

i just did my first build and it looks like i'm having the EXACT same problem as you....

the whole thing turned on just fine. when i rebooted to attempt to start installing vista absolutely nothing happened. well actually the LED's in my fans blink about every second if i hold the power button down. i can also hear the power supply clicking about every second seemingly in an attempt to get things rolling. i bought a new power supply today (albeit it is probably as crappy as my previous one, but it does have 50 more watts) and it's the same story. my MB light is on as well and will turn on and off accordingly as i plug in and unplug the power supply. i've tried disconnecting the fans and all other unnecessary things. still doesn't work. both the PSU's i've tried are @ raidmax's lower level of quality (each is worth about $30).

i really really really really really really really don't know what the hell is going on. this is such a mystery...AND NOT THE FUN KIND EITHER!
