Bought this for ₹22k, roast me if you want.
I didn't want to buy had to

I didn't want to buy had to
I am getting this gpu for ₹15k brand new from a local market with warranty.
Now there is a problem,
My psu is 6 years old: corsair cv450
Should I go for it because there is no other choice otherwise I have to go with gt710 4gb ddr3 for ₹4600(idk why am I even mentioning it)
She used to come to my home daily for food even 2- 3 times a day but after 2 weeks she just disappeared like hiding from me or even not coming close to our balcony or neighbourhood.
My current system(6 years old) is:
Gigabyte h310 m h 2.0 mb
i3-9100f
Corsair CV-450 psu
My rx-550 gpu recently died and as I don't have integrated graphics, I rely on an external gpu but I am not really getting any that matches my specs such as gtx1650/1660 super or rx-6600. But I am getting an rx-580, so I have two questions:
Should I buy this card for ₹15k
Is this card really going to be worth it for my system?
I am looking for an old or new gtx 1660 super gpu.
Spent more than 2 hours going to around 10 shops but no luck. I am looking for rx6600
i3-9100f cpu
Corsair 450 watt power supply
Gigabyte h310 m h 2.0 motherboard
1 RAM stick 8gb
My budget is around ₹20k
My previous gpu was Rx -550 which is causing no display and I checked my system with another gpu that posted but my gpu didn't though I didn't check it on the other system.
I tried everything I could but PC is not posting. My PC specs are:
Motherboard h310 m h 2.0
CPU i3-9100f GPU RX-550
1 RAM stick 8gb
