Will 300W PSU good for following Configuration

Hi Folks,

I am replacing my existing Motherbaord & Pentium P4 Processor with new GIGABYTE B75M-D3V motherboard and G2020 Processor, and I am planning to utililize my existing ATX Cabinet having 300 W PSU (from Mecrury).

PC will be for a typical home use - Browsing, Video/Movie Play etc. and no gaming etc.

Could anyone please comment on compatibilty of this PSU or any other suggestions?

Thanks,
