accidentally dropped it half a inch fall 

I'm saying it's not worth it. 
 
Anything you could buy, you would buy at too high price to be profitable.  Let's say you get lucky and buy a RX 570 used for 150$  (they sell NEW in local store for 250 euro here today, and 6 months ago I couldn't sell my RX 470  for 80 euro, can you imagine that...)
 
If you pay 0.1$ for 1kWh, you're probably gonna end up making something like 1.5$ A DAY after paying the electricity, probably even less... AS LONG AS the price will remain at around 1200$ for ETH, or whatever bitcoin is worth now.  
 
You could be mining for 60 days or as long as it takes for the minimum payout amount (for example 0.01 ETH or whatever) and by the time you get enough ETH or Bitcoin to convert to cash, the price may be only 900-1000$ instead of $1200, so you'll be paid only 1-1.2$ a day 
 
Anyway, the basic point is that you're still making 20-40$ a month with a single video card, with no guarantee prices will remain there... so if you pay $150 for a card, it would take you 4-5 months to recover the money you invested and then start to make a measly 20-30$ a month profit. 
 
 

it can handle it, but its still a crap PSU. You can use but i'd highly recommend replacing it.

It will probably be enough, especially if you modify the gpu clocks on the 570 to get lower power consumption.  
 
However, I suggest you don't buy a video card now, unless you don't pay for electricity - with a rx 570 your profits will be very small, you'll recover the cost of a video card in half a year or something like that. By that time, there's a high chance the prices will go down, or the complexity of the algorithm will increase and it will be even less profitable to mine.
 

core count isn't the only thing that makes a cpu.
^.

No, all modern GPUs have an encoder yo take the load off the CPU. 

We don't know how long the cv550 would last. It won't explode, it has the proper protections after all it's just not the best. 

I mean yea but I gave some options. Like a system power 9 500w or a cx550 should be plenty and are better. 

it is near the pcie connector thank god i thought something is wrong i just plugged my new videocard today thanks alottttt i even thought i broke it im scared so i asked here
