$29\ EVGA BT 450W 80+ BRONZE ATX PSU
Another budget build, and another delve into the realm of EVGA’s superbudget BT450 power supply. Yup, this is one of those kind of builds. It’s hard to recommend anything else when it comes to super-lowend power supplies. We always suggest that you go with a known brand, because it provides you with a bit more peace of mind, and if things ever go wrong (and they can and do), you can rest assured that there’s some form of warranty behind you. And, let’s face it, EVGA’s warranties have become legendary.
That said, is a 450W power supply enough? The answer: Yup. From the wall, we’re expecting this rig to draw around 50W total peak power, or within that area. You could throw in a GeForce GTX 1080 Ti 11GB (seriously, though, don’t do this), and still be left with 150W of headroom to play with. So, there’s plenty of room for expansion later down the line if you want to swap out that GPU, CPU, or memory.
