Silverstone SFX 450W

This is a 450W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the SFX form factor — confirm your case lists SFX support. 450W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $91.88, which lands it among mid-range options. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
