What PSU do you need for an GTX 1050 Ti?
The GTX 1050 Ti draws up to about 75W under full load. On its own that only tells half the story — your total system power (and so the PSU you need) depends just as much on your CPU, drives and cooling. This page sizes a supply for the GTX 1050 Ti paired with a Core i5-6600 / 6600K; if your parts differ, the calculator gives your exact number in seconds.
Paired with a Core i5-6600 / 6600K, this build draws about 255W at peak (75W GPU + 90W CPU + system). A 500W unit runs it at ~51% load. Absolute minimum: 400W.

FAQ
Is a 400W PSU enough for an GTX 1050 Ti?
It's the bare minimum, but we'd recommend 500W. This build peaks around 255W, and a 500W unit keeps it near 55% load — the efficiency sweet spot — with headroom for the GPU's transient spikes.
What efficiency rating should I get for an GTX 1050 Ti?
80+ Bronze or Gold. It's the best balance of price and efficiency for a build this size. Never pair a good GPU with a cheap unrated PSU.
