Electronics PSU size?

So i successfully swapped my XPSP3 email box to an SSD using an IDE to SSD convertor. Please dont ask why i dont just upgrade the hardware, i wont.

My question is this: i only have a 1.2G Celeron PIII based proc, a single 60MM CPU fan and the OS SSD. Ive been told the max the CPU can draw is 30W and the fan/SSD would be negligible. The mobo is a Gateway mATX Intel 915 series with on board video, but i only access it via RDP.

Currently i have a Thermaltake 430W PSU on it and i know its overkill. Most SFX PUS's are way more than i want to spend, so im wondering if i can get away with a smaller PSU around 75W or even a pico PSU with a wall wart.

Any ideas?

 

picoPSU will be enough, if you don't use a dedicated GPU, but the price for these is $80 aswell (picoPSU + powerbrick) so a SFX-PSU for $60 is a good option.

 

What he said.

 

Thanks guys, one more ?, will this work you think?

Should do. Take it your motherboard needs a 20 pin not a 24 pin then?

I didn't realise you could get them that cheaply!

 

Yea, i figured the PIII equiv would have tipped that off

Sorry, its an 815 not 915 lol.

 

Yeah, this should work. The Celeron PIII 1.2GHz draws a max of 31 Watts according to ark.intel and as it's an old PPGA370 it should have a 20-pin ATX-connector aswell.

 

Yea i thought so, but the PSU Calc page said i would draw around 100w which seemed really high considering i think it came with a 70w from Gateway.

 

id suggest buying a 120watt picto psu just in case you plan on adding more hard drives

 

Pffft lol. I just downsized from an 80gig IDE to 40 gig SSD... it ONLY does email.

 

Just wanted to update this, the pico is installed and running fine
