My current PC build is as follows !

pentium 4 @ 3 ghz with HT
2 HDDs
1 GB ram
PSU : iball LPE223-400
(+3.3v-25A | +5v-32A | -5 V-0.3 A | +12v-17 A | -12v -0.8A)
i know this build is very old and crapy but i will be buying laptop in near future.
so i want to buy a new graphic card for time being. I searched and liked this entry level card (AMD/ATI Radeon HD 5450) link : http://www.flipkart.com/powercolor-amd-ati-radeon-hd5450-1-gb-ddr3-graphics-card/p/itmd5vrzwe6g9qry?pid=GRCD5VRZZ9URJFXD&ref=50aa7310-0f76-453e-9927-a9f3de4fd663
i dont know my PSU wattage rating. some say its 250W and some 400W.
will my PSU be sufficient for this card ? i am on a tight budget ! are there any card which will run on this psu or i'll have to upgrade it

PSU brand iball model number LPE223-400
sticker readings says (+3.3v-25A | +5v-32A | -5 V-0.3 A | +12v-17 A | -12v -0.8A)
i dont have any external video cards . i do have ati radeon xpress 200 inbuilt mobo graphic card which is as good as nothing!
