Hi Nick,

Yes, that number does sound correct. I will be working on the PSU thingy next. Hopefully that is it and will be easily resolvable.

PSUs are so cheap now you might just as well replace it with a good high power one and see if that fixes it. If it doesn't then at least you have a spare power supply in your tool box!
