Prit Did you use psu calc?
Those Calculators are for high efficency psu's only.
In my country we use low efficency power supplies only and then blame power companies for high electric bills.

i have not used any type of calculator upgrading your hdd and cpu will not require a new psu but if you upgrade your card to then depending on the card a new psu would be needed or if you use a fx 9570 type of processor with has a TDP of 220 watt then .

My problem is that my pc isn't operating with my graphic card because of low wattage psu.
Without installing graphic card, hdd and cpu upgrade would run perfectly on that psu as you mentioned.
