@steveabn , welcome to the Community.
You can actually upgrade to a 400W PSU (L69242-800). It is the same motherboard as the TE01-1175tx. It has the 400W PSU listed in this Power Supply Cross Reference Chart: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model...
Here is the PSU on HP PartSurfer: https://partsurfer.hp.com/Search.aspx?searchText=L69242-800
You can order it by clicking the box next to "Add to Cart".
