  • Power needs

    Im putting together a carputer system and i already have an extra celeron mobo and processor lying around, will a 140 watt psu be able to handle this setup with a minimum video card and gps? What's the rule of thumb for how much power you'll need, i've tried those psu calculators and they always say i need around 160 or so. What do you think?

    calculate the total power you will draw out on each voltage rail. example how much will you pull off of the 12v rail and the 5v rail and the 3.3v rail. good luck

      I ran a Celeron 633 with AGP card and GPS on a 90W M1-ATX. There's no problem. The calculators play it safe.
