Where i live, the psu are scarce and right now you cant find any at all. My psu broke a few days ago and i urgently need my computer operational. I have decided to buy a used psu. I wanted to ask how many watts will i need for an i7 10700k (quite overclocked) a water cooler (evga 280mm but soon will change for kraken x73), 2x sli RTX2080ti, 4 case fans and a lot of rgb strips etc plus a samsung ssd 870 evo 1tb i think it was and a cheap seagate hdd also 1tb. Also how do i test the psu to see if it works well and wont die in a week?
