Can I use old power supply ?

But your old power supply will not make a shiny new PAL amiga 1200 magically an NTSC model... it is and forever will be PAL until there is a hardware change/modification to the chipset.

Most OS based software is agnostic regards NTSC/PAL....   well written OS based software should run in whatever screen mode has been set for either its own screen or window mode on workbench.

I believe there is much more PAL floppy games than NTSC, most of the large game publishing houses were European based.

PAL games were mostly 320 x 256 x 50hrtz
NTSC were about 320 x 200 x 60hrtz

PAL can have a very slight flicker... but NTSC has a very horrible red with bleeding black edges called "ant crawling" on vertical red lines. Quite ugly even on the best of displays.

The 320 x 256 also gave more raster time for interrupts so some PAL games had the advantage of doing more things per screen refresh. Some games could not be reproduced well on NTSC because of this. This happened quite often with C64 games.
