I have stock 3 years old 400 Watt PSU, is it ok for the below

i3 3210@3.2 Ghz
GTX 750 TI OC 2GB DDR5
6Gb DDR3
Intel DH61HO
1 TB HDD

the gtx 750 TI supposed to be low TDP but when I checked online its need 200+ Watt on load status.

what do you think?

The power draw of your system is exceptionally low, you have a processor that will not draw more than 50w, and the GTX 750ti runs directly off the motherboard PCI-E slots, being restricted to a MAXIMUM of 75w.

Even on a no-name PSU, Your main components are already only at 125w. That is why the 750Ti is great as an upgrade for older/prebuilt PC's. Its power draw is so efficient you are essentially able to simply drop it into a PC without issue.

---Your 400w older PSU should not pose any issues with the 750Ti, even if it is a 3 year old OEM PSU.
