They should, unless you have a computer case which isn't default ATX by standards or you have a motherboard that doesn't like getting graphics cards it intself.
If you bring it to a local computer store they can make it absolutely sure. Doing that remotly would like telling an other human being to move his arm foward, stretch his fingers out and don't forget to keep breathing in the meanwhile.
Don't let the shop keepers talk into you though, most of them like telling people they should get theirselves a new computer.

Can cannot reply to that, the only powersupply's I see on that website I recognize from makes I know having a good name here, are terrible weak ones, and the better ones are expensive to say the least.
For a pound or 350-400 you could get yourself a new computer, but NO, I'm not going to make an example tonight.

If you can get some screws out, disattach some plugs and put something else instead of it, you can replace a powersupply. There are plenty of video's on google video or youtube on how to mount a powersupply, or even how to assemble an entire computer.
