180-190 F Sounds pretty hot for a CPU, I assume you mean CPU when you said my computer. Though perfectly fine for a GPU.
A system can power off due to a faulty card, insufficient power or overheating. In my personal experience, overheating will generally cause lockups as well and graphical distortions before getting to a point where it powers down the system. The GTX275 IIRC was not around 2008, so I assume its an after market card.
Nvidia recommends minimum 550W - http://www.nvidia.com/object/product_geforce_gtx_275_us.html Thought you probably want to go higher if you have additional components.

I'm no electrical engineer but here's my laymans take on this. When the components that you are running ask for more power than your source can supply you're going to have a problem. Your computer is shutting down. My fear is that you are going to fry your power suppy and maybe take your video card and your mother board with it. It hasn't happened to me but there are endless stories on the internet of this happening to people. If you are running a generic power supply I would suggest getting a new power supply asap. The psu is not the most interesting part of a computer... but everything else depends on it and a cheap or under powered psu can make for a really bad day.
