As I understand it, the Zotac recommends a 400 watts PSU. Power consumption is 60 watts.

If the DVD is not running its power draw would be negliable, just a few watts probably. If running (reading/writing) the actual power demand could vary with make and model. Maybe 20 - 30 watts.

And adding more RAM will increase the load a few watts as well.

There are a variety of online calculators to help establish the necessary PSU wattage. However, such tools are not without controversy so maybe try a few just to see if there is some concensus regarding the PSU wattage you need/should have.

Or manually add things up. Perhaps a simple spreadsheet customized to your system components.

And PSU quality counts - pushing the wattage limit...

So to answer your question: the wattage you save will not make a difference. You need to think about the bigger picture and overall expected load on the PSU.

I see, in nvidia's website it says minumum 300w. I thought zotac is the least power consuming cause it is little and has 1 fan. Should I go for MSI's twinfrozr? It hasnt got pin connector too, but it is overlocked I think. And some of people say dont listen to the manufacturer's recommends

Not familar with the MSI twinforzr.

However the "rules" still apply. The PSU must be able to meet the power demand of the system and all of the installed components.

As for manufacturer's recommendations: You should listen to them and understand them in detail. Not staying within the recommendations may void your warranty. Or, even worse, result in some damage to other components or even all of your system.

Electronic devices are not at all being made as well as they were not far back. Design, components, assembly are done as cheaply as possible usually with some built in EOL (End of Life) expectation. Not built to absorb damage or last beyond some engineered in time.

Pushing the specifications or otherwise going beyond the recommendations is likely to shorten the life time even more. And cost you more as well.
