Why bother making your own power supply if you do it badly? You can probably get a crappy cheap Chinese power supply off ebay for much less than it cost for all of the parts and it'll be much more reliable too.
You'll be lucky if it doesn't catch fire or electrocute you.
Don't Think Like a little baby ....Hero

Its was working fine for me
I am just using 1 amp of transformaer....but I can Handle upto 20A of current and 1 amp is nothing as compare to 20A.
Thats why Its will never catches fire at 1A
