Really, if you can't find anything on Google, you'll likely have to contact Deepcool for help obtaining a replacement if you no longer have the one it came with. While lots of popular PSUs will have available aftermarket cables, this PSU is a rather mediocre group-regulated PSU, so there's little hobbyist interest and thus, it's not profitable for companies to produce compatible cables. So it's a bit of work to find a replacement; if Deepcool doesn't help and you can't find one online, your options become to replace the PSU or find someone selling an old broken DA700 cheaply and using the cable.
