thermatake

I have an old system with the following specs : Core i5 3470, Intel Motherboard DZSL77-50k, Corsair Vengeance Ram 8gb, a GTX 1050ti requiring 6pin power also, and 3 sata hardrives. Currently in my budget I can get only the two supplies mentioned in the title. Please guide me which one should I buy?

Hi guys recently bought the Asus ROG Strix x570-E gaming mb (installed a Ryzen 7 3700X fyi) I asked the guy about water cooling and he suggested the thermaltake water 3.0 now that fits my thermaltake case but the sockets don't match up with my amd mb. Did he accidentally give me the wrong socket...
