Im buying a replacement psu, is size (volume) a problem?

hi, i blew up my psu. i plugged it into a 220V socket with the switch on 110V. i dont normally, but this time i did, and i hope its only the psu i have a problem with.

now while looking for a new one, i dont know if i can buy any, or i have to worry about the size and wether it will fit in my case.

the one i blew, was model :

"Delta Electronics
GPS-350BB-100A"

its a 350 W psu and has a voltage change switch. now when buying a new one,
could i just go to compusa and pick one up, as long as it is 350 W and looks like it will fit?

i dont still have the one that i blew, its gone.

and also how much should a decent one cost? 30 dllrs?

i dont mind paying the exta 15 though, if its reccomended i gtcik to 350W

does it just have to be atx?

more important, how many outputs do i need? most i see come with dual output, so i guess thats standard, do they make different normally?

Hi.

Yes, it needs to be an ATX psu as it's the industry standard in everything from physical size to voltage regulation.

I'd stick with a 350w psu simply because your last one was, so why mess with it.

You'll need enough connections for the components you have, so count up molex's required (optical drive(s), ide hdd(s) etc). I believe the 5200 is powered through the AGP port so no worry's there.

New psu's have a 24pin connector or 20+4 connectors for the motherboard, check your motherboard to see if you need a 20 pin or 24 pin because if you need a 20 pin you'll have to get a psu with the 20+4 pin connectors (you could get a psu with a 24 pin motherboard lead and get a 24-20pin converter but it's more cost and messing about).

Also, check if the cpu requires a separate 12v lead, these usually take the form of a 4 pin or 8 pin slot. I doubt very much the motherboard in question will require an 8 pin but it may need a 4 pin for the cpu, so check your board, and if so, then check the psu you're looking at.
