My pc has the following specs
Asus H61m-D motherboard
I3- 3220 3.3 ghz processor
4gb ram
450w power supply(dont know the brand)

Now i am looking to buy an Evga gtx 750 ti SC. I chose this because it requires min. 300w power supply while the zotac one requires minimum 400w. Can any1 tell me why there is a difference in power supply even though both consume same 60w power?
Also will my system be able to handle this configuration without harm to motherboard or other components??
PS: my seller tells me the zotac and MSI ones won't.

Changing the PSU would cost about 7000rs more according to my seller(with cabinet). Im not sure i would be able to spend that much.

Okay thanks. Any low power equivalent which might be able to run all new games?

Talking about any other GPU which my power supply would be able to handle well
