So Why are PSU prices now rising?
Not Every PSU, just high capacity/efficiency PSUs that can run multiple GPUs in a mining rig.

so why does it seem like half of the component prices in a new build are raising or completely out of reach for some?
A big part of the problem is the DRAM 'shortage', as well as the flash shortage (although that's improving). GPUs, as well as many other PC components, depend on DRAM. Both of those shortages can be at least partially attributed to Samsung's continued refusal to increase production as demand increases. Samsung's competitors also don't ramp up (although a lot of them are far smaller). Why not? I'm not entirely sure, there is some possibility for collusion that I believe should be at least looked into.
I mention Samsung in particular because China is apparently investigating them on price-fixing claims for DRAM. The threat of investigation prompted Samsung to announce an increase to production (which makes them look guilty). But Samsung set timelines of several years until production is ready, at which point DDR4 will be practically obsolete.

Is there some sort of money grab plot going on in the industry causing some of the issues we are seeing especially with GPU's?
Well yes, there always is. The computer industry has always been dirty with price-fixing and collusion, especially on new technologies. It's happened before with LCD panels (which they got caught, notice how much cheaper TVs are now compared to 5 years ago?), DVD burners (they also got caught, I never did get the class-action settlement that I applied for). In '02 - '05, five companies (including Samsung) plead guilty to DRAM price fixing - its certainly possible for it to be happening again. The question is which companies have crossed the line far enough (yet) that they will get caught.
But is it GPUs in particular? I'm not so sure, at least not yet. I haven't heard of Nvidia/AMD increasing their MSRP or charging increased chip prices to their 3rd party partners. They don't seem to be profiting much off of the situation outside of increased overall sales. I do think they will increase MSRP on their next set of cards, though.
