Which one is higher quality? Internal bits and pieces wise, which one has better quality?

More about : corsair series

Both have their problems. If you are truly looking at a Corsair line, the AX series is of the best quality, followed by HX, then TX.

I'm just trying to buy something for a HTPC that's both cheap and good and right now the RM450 is on sale on Newegg Shellshocker so I think I''ll go for that.

I would avoid all CX series (Tier 3). RM series depends on the model. RM 750/850(Tier 3) and RM 550 is (Tier 2).

Most people do not stress their PSUs anywhere near hard enough for any of the quibbles against Tier-3 to really matter so unless OP can get a Tier-1/2 PSU for about the same price as a Tier-3, there is no reason to lose much sleep over it.

Due to limited availability at the time, the cx-750w looked like the best psu I could get... Is it worth buying a new one? What makes it so bad? Why is it to be avoided? Is something at risk because of it? Is it bottlenecking things? Is it a dirty bomb in disguise? What are we talking about here?

The CX,CS, and RM (except 550w) all use low end poor quality capacitors. They fail when subjected to any real heat and do not age well. There have been multiple posts on here from uses with a CX unit frying their entire computer.

They are fine for office or low draw builds, but for a serious gaming computer I would DEFINITELY get something better. XFX has AMAZING units for the same price that are light-years better.

Well, I brought the RM450, probably will draw less than 100w from it when I use it. PCPartPicker estimates 138w for my build but I seriously doubt I'll even hit 100w for a HTPC.
