Graphic Card:MSI nVidia GeForce GT 730 2GB 128bit - N730-2GD3

I want to know will it work all together ,and i also want to know what power supply do i need, i have an old power supply 350W but i don`t know is it going to be enought.

When i go on http://extreme.outervision.com/psucalculatorlite.jsp it says that recommended wattage is 250W.I don`t believe in that so i want to ask you is 350W power supply going to be enought?

My other komponents:

HDD:SATA2 160GB
DVDRW:Samsung Writemaster
Power Supply:THERMAL MASTER ATX-12V TM-350

PLS answer me as fast as you can.

You're right. 350W is not enough. I would aim for 500W to be safe, but a 450W good quality supply would probably suffice.

Gil is wrong. You only need 300w for that video card.

That is 300W RMS. Most PSU's boast their max power instead of RMS so you need to multiply by .707 in most cases. I would say go ahead and try your current PSU. If it blows up and a capacitor goes out, just buy a new one.
