Vostro 3881 PSU, GPU Upgrade

Hello, I've been using Vostro 3881 for two years now. And i wanted to upgrade my GPU into gtx 1050. And i found out that i need to upgrade my PSU too. Does any psu work with the 3881 model or am i only allowed to "upgrade" into 360w dell psu? Or perhaps 260w is enough for gtx 1050 and i3 10100?
