I'm planning to buy all of the components in this month, except maybe the gpu (due to availability). I'll use a cheap gpu for display output till then. I want to able to play at 1440 120hz+

 

I was trying to pick a psu from the psu tier list but I can't really seem to find a good power supply which is not out of stock or isn't very expensive even after searching for hours, it would be very helpful if you guys can point out some

 

ps: The prices in PCPP are in INR but converted as PCPP has dropped support for india ans the cx650 (non-m) and rm750x both are out of stock everywhere
