Will any PC powersupply be enough?
 

I pulled a Bestec 250watt 13amp on the 12v and made a power source out of it. I am gonna buy a Hyperion DC charger and am wondering does it matter if the PSU is generic? I know it does when powering a PC but for just charging lipos I don't know. I do have a better quality PSU I could make into one but I hate to tear it down if I don't need to.
