Yes, that power supply is good (Delta made 525w unit) for anything up to and including a GTX 1050, so long as no PCIe (PEG) six or eight pin power cable is required, which it isn't for everything that is GTX 1050 or lower. It is fine for that GT 730. It might even be ok for up to some models of GTX 1060 as it may actually have a six pin PCIe power cable but it is difficult to determine from the available information. Either way, fine for what you want to use it for by a long shot.
