U2414H, power cord?

Hi there, I just received a used U2414Hb monitor from a friend as a hand-me-down, and he didn't give me a power cord. I'm trying to buy one online, but I'm confused about which one to buy. I looked up the user manual online, it wasn't very specific: u2414H user manual.  I found this one: https://www.amazon.com/Dell-45W-Replacement-AC-Adapter/dp/B007OYLNGA/ref=pd_lpo_vtph_23_bs_t_1?_encoding=UTF8&psc=1&refRID=AP17BZCKNZDNCP0MCMJS&dpID=61Ou6DtofhL&preST=_SY300_QL70_&dpsrc=detail, but I wasn't sure if it was the right one.... I just don't want to buy a cable, and then not have it work, a waste of money.
