My PC restarting with the below error Message

It looks like cpu is not getting enough voltage so under load its giving you errors.

Have you changed anything in bios or all stock ?

I think you should first rule this out before buying a power supply.

Also your PSU is quite good with plenty of headroom... you could easily run a much more power hungry GPU.

If your settings are auto or manual try setting vcore to 1.35 and lower cpu clocks a little and run tests again.

I replaced my 5 year old Antec Earthwatts Pro 750w with Coolermaster MWE 750w PSU and the problem is gone.
 
Happy to hear your issue is resolved .... quite surprised 750W PSU wore out with your config ... but it has been 5 years so its not terrible.
 
After registering in CoolerMaster website for my newly bought PSU it show like below:

What does null stands for?
 
you should start separate thread for your Antec PSU warranty claim, will help others to decide.
I sent a reply to rptech service centre in chennai attaching my invoice, also posted in Acro for Gamers in facebook, also in Antec India in facebook, also sent to WhatsApp number given in Antec India facebook page and also on Antec Subreddit. Let us see who will respond.
 
Primeabgb where I bought the Antec PSU told me to send the PSU to them in good packing and I have to bear the to & fro shipping charges along with the Invoice. This is the reply I got because I mailed them about the issue with RPtech India regarding Antec PSus.
