|Getting the exact one from Packard Bell, even if you can, is likely to be expensive.|
Most likely there is a Corsair PSU around which will fit inside your PC (around £50) but you would need to do the donkey work on that. The PSU should be at least the same Wattage, should have all the required voltage outputs (most have) and at least the same amperage on each of them. I've bought the odd ones second hand on eBay which have worked out.
Keep watching in case someone has particular knowledge of your B2619 UK.
Err.. it hopefully goes without saying that if you are in the UK the PSU should be suitable for 230V 50 Hz.
Do the paperclip test first.
Always pop back and let us know the outcome - thanks
