I've been asked to find a cheap(ish) scanner for a friend's Mum. This will be a Christmas present, and the maximum spend is around £50. All the ones I have seen so far are USB powered. The PC for which the scanner is intended only has a 200W PSU. It's quite an old, low spec machine. Would a 200W PSU have enough guts to power a USB Scanner? I was looking at
this Canon, from Ebuyer. If this is a non-runner, due to the small PSU, can anyone recommend a mains powered scanner for a similar price?
