pc short circuit

SBS7484P SG

awhile ago, i was messing around with some fans with a molex -> 3pin adapter..

by accident i let the exposed 3 male pins brush the metal casing. there was a great spark where the pins touched the casing, and i think as a built in safety function, the PSU shut the pc off, only the blue power LED was left on.

i turned off the power and started the pc again, all as per normal, according to Speedfan.

voltages are as per normal too so im not worried my PSU is fried.

what i'm worried though is, does doing this harm the other components of the pc?

i know obviously its bad for the psu but will doing this take out my hard drive, or take out a fan or two? =x

Wth?
If its gonna spoil then it will spoil then by that time go get a new 1 lor since u already made it spark.

SBS7484P SG

the fans didn't spark.

the converter pins caused the spark. i had no fan attached to it at that moment but i did have a myriad of fans already attached to my motherboard.

and my motherboard derives the power for those fans from none other than the power supply. so i'm just worried that the fans may have received a power surge and the motor goes flaky or something

i know it's not that easy to kill a fan, (i've tried), but i'm pulling all the stops for these because they're real expensive fans, rare, and some of them run incredibly well even after being used for 10 years.

regular cleaning, inspection and oiling keeps them alive

i think it should be ok since it wasnt connected yet. no current running thru the fan.

yes the other fans are definitely okay but i'm not sure if the ones already running in the PC are.

you can't exactly get those around singapore - only way to get those is to buy a brand new lenovo ideacentre PC.

and of course, my PC isn't a lenovo ideacentre.

got them off ebay, an assortment of brand new AVC fans in a sealed box for nearly sixty bucks.

given that they're top-of-the-range hydraulic bearing fans... that price is somewhat justifiable.

No worries

When a short is detected, they psu basically shut off or cut power the other rails(if i am correct)

thus your other stuffs just experience something liike a blackout

according to the design document, the psu must be built to be able to withstand continous shorting, but i think doing it too often will will cause damage

just throw the whole thing if u do until like that!

go buy a new assembled computer.

thanks dude

PSU's just a cheap LITE-ON 400W one.. so if it blows up i'll just take the fan out of it and get a new one. can't RMA the psu since i cracked it open to put one of those AVC howlers inside

at least now i know my fans won't be in danger

i am planning to do that - soon.

most of my PC is basically stock from HP - since they gave me a rather beefy CPU cooler and some great fans that i had no qualms about power with.

only mods i've made was the addition of more, and faster RAM, and changing the stock ATi X1300 GPU to an X1550 one. the difference wasn't much, just twice the memory on the 1550, but since it was retailing at just $55, why the heck not.

Your PSU should be fine. Newer PSUs have all the safety features like OverVoltage Protection, OverCurrent Protection and so on. They just power off, just like when I accidentally shorted the FP connectors on an ancient mobo. The new PSU just shut off, and that PSU is sitting inside my current PC. At least thats better than my old Celeron PC. Connected a 2nd SATA HDD and the thing blew up. As long as it didn't blow up, it should be fine.

SBS7484P SG

hahaha, alright.

thanks for the advice dudes.

i did kinda get a shock due to the magnitude of that spark there, but i guess it's all okay now. haha

oh yes, speaking of power supplies..

does anyone know of a uh, good quality power supply that's this size, and pumps out, around enough watts for a dual-mid-end card set up?

can see it's noticeably smaller than regular power supplies, but i'll need one of this size to fit in my mATX casing.
