Where can I find all types of accessories for my PS3?

May be...

For example, I need a power adapter that bends 90* or that can rotate 180*. The standard stuff takes up a lot of room in the back of my component.

Do you mean this?

looks to me that your PS3 is in a very tight and crampy place... without enough room to breathe, your PS3 will overheat and get the yellow light of death.. the space you need for cables in the back is the minimum space you need for your PS3 to have enough room to breathe and prevent overheating.

I dont think they sell that...
