Hey all, I be new to the boards, so, Sup? I’m hoping someone can shed some light on the problem for me. The power supply on my wife’s Dell E310 went out after a thunder storm. (it had an amber blinking light, according to dell user manual… PSU prob.). As I’ve read from others, Dell told me also that buying any other power supply would burn up the mother board. I read that they didn’t know what they were talking about and that another PSU would work. So, I matched up specs to the original as best I could, except that the original was a 230w and I went to replace it with this one… Ultra X Connect VS 400w ATX PSU Meets ATX Version 2.03 and ATX 12V Version 1.2 specifications Short Circuit Protection In-rush Current Protection Thermal over-load cutoff protection (1) 20/24 pin motherboard connector (1) 4 pin +12V motherboard connector (6) 4 pin Molex connectors (1) 4 pin floppy connector (1) PCI Express Connector (2) SATA connectors AC Input voltage: 115v/230v AC Input frequency: 50-60hz AC Input Current: 7.5 (RMS) for 115vac input 4.5 (RMS) for 230vac input Max Output Current 160w +5v,30a +3.3v,18a 240w +12v,20a 3w -5v.,6a 7.2w -12v,.6a 10w +5vbs,2a Max Combined Wattage 400w The system only needed the 24 pin, the 4 pin +12v, (1) Molex connector, & (1) SATA connector It fit into the case perfectly. I turned it on and it displayed on the screen during initial boot up that it couldn’t find the drive SATA 0. I turned it off, unplugged from the wall, waited for the mobo light to go out, and saw that I had plugged the main drive SATA connector into SATA 1 plug, rather than SATA 0 plug. I switched it, plugging the main drive SATA connection into the SATA 0 plug. I plugged it back into the wall outlet, and pushed the power button. This time, everything started to sound fine (i.e. heard the hard drive startup, ect.) and then a high pitch click that sounded like it came from behind me, and a sharp flash of light from around the PSU area of the inside of the computer. Now, there is absolutely nothing happening. No blinking amber light... nothing, it's totally dead. Obviously, I’m thinking I did something wrong, or that maybe Dell was right. I’m hoping that it was just the PSU that just fried before my eyes, but as my initial question. Can anyone tell me what the heck just happened and why? I would immensely appreciate it.
