How much power will this draw you think?

**_ZaP_** · 03-06-2004, 08:38 AM

Not sure if I need a 100watt or 150 watt psu for this setup

+ VIA M10000
+ 40 or 60 gig 7200rpm regular hard drive (I want the faster access time of a regular HD instead of a laptop HD, but if there is a BIG difference in power consumption let me know)
+ DVD rom
+ GPS mouse (maybe)
+ TV Tuner card (maybe)
+ Another small USB device (maybe)

I am just trying to leave room for future expansion if I ever go that way. Additionally, what is the best place to tap 12v in the trunk of an Audi A4?

Thoughts? Thanks.

Sweet!

=\

Except that calculator doesn't have VIA boards. There was an article somewhere that had power consumption on VIA, but I can't find it anymore

Cool, that does the trick. I think I can get away with just a 90 watt psu.

Always better to give your self a little lee-way though. Your motherboard will appreciate it, im sure.

Remember that power sim does not calculate peak power draw, just average draw. If you run over, you'll do it at boot/drive spin up time. That's tipically when the most power is drawn. Keep in mind a laptop drive draw about 4 watts, and regular drive draws about 15. A 7200 rpm drive would probably draw more, especially at spin up. Are you using a full size DVDROM? That's about 21 watts vs. a slim drive at about 5.
