I was wanting to upgrade my PSU to a more powerful one as I am wanting to also upgrade GPU to a GT 730. Does anyone know a good PSU that would fit my case?
Take a photo of the PSU's nameplate and post it here. You may be able to use a GTX 1050 Ti for much better gaming. And if you can't, look into the GT 1030 instead. It will be better than the GT 730... and will run on your PSU.
