Is there an small but strong enough battery (rechargeable) than I can use an inverter and get it to 120V and power an PC offa it?



Or is there such thing as an "Battery PSU"?

APC is the big name in backup power supplies. Businesses use these often in the event of blackouts to prevent losses of data. Generally they won't give you more then about 2hrs. of time in order to save your work. Their main product page is found at http://www.apcc.com/products/category.cfm?id=13&subid=5

Just at one shopping site where prices between vendors are compared the APC name always comes up the most as the leading brand while there are various types available. http://www.nextag.com/serv/main/buye...ID=14411433511

No no I need like an portable battery for my desktop... It's about an project... (shh!)



How many mAh do you reckon I'll need to power an Celeron 1.2Ghz, generic mobo, 512MB, FX5200, mic + headphones, 24x CD rom drive, 300W PSU, floppy USB mouse + keyboard...

A 12v battery for an auto would see all the amps you would ever need. But it mainly depends on the type of battery used. That decides how many are needed. Then you have to work out the means of connecting the power more directly bypassing the ac supply. That won't take a 12v dc input. The board will however once a standard connector is wired correctly.

You might a lower price for one somewhere else if you shop around some. Usually by searching for a specific make and model or type you'll come across a shopping site with a few links comparing prices seen at different vendors. But that product line seen there is a start for what you are looking for.
