Power Cables - Stock vs. Budget

@kota1 

I would upgrade the wall socket first, get a power conditioner second, and get power cables last. For wall sockets you can check Pangea or Synergistic Research. 

why would you not recommend that the OP get dedicated lines installed first with hospital grade outlets first vs just doing wall outlets?

you suggest a power conditioner......how do you know that the OP even needs one?

i would still do the dedicated lines first, then look at power cords and conditioner last if that is even needed, as again, he might not need the PC and no sense of spending money if you dont have to .
