Windows 10 Home OEM key is around RM 300 if you buy from retail/physical shop, I am not sure what is Techview's pricing on Windows key, you need to ask them for more information.
If you look for Garage Sales, there are actually many sellers selling at ridiculously low price, you can buy from them if you dare to take the risk, need to beware of fake/stolen/duplicate key though.
Techview is located at Jaya One PJ.
I looked up the PSU you suggested, and I see it has no efficiency rating. Would it be worth investing in a PSU with 80+ Bronze rating?
