What kind of graphics card could I run in a 460w HP PSU?

Here are the specs of my computer.
What cards could I possibly run on this machine? I'm wondering if I would have to replace the PSU to upgrade to a better graphics card. (possibly around from $100 to $250)

Is the PSU 80+? Does it have a PCIe power cable on it? It is likely to be a "minimal" PSU without being junk, else HP would have business-wrecking warranty problems.
If its not 80+, but does have a PCIe power connector, you should be able to run a HD7770 or GTX650Ti on it. If it is 80+ and has that connector, a HD7850 or GTX650Ti Boost Edition (perhaps even a GTX660Ti) should be safe. If it does not have a PCIe power connector, and is not 80+, I would not use anything more demanding than a vanilla (i.e. 800MHz) HD7750 or a GTX650 "E" edition, neither of which need PCIe power.

I'm not so sure about if it's a 80+ PSU, but I'm sure that it has the PCIe power. Would it be a risk as to running a GTX650TI boost on this?

There might be a little 80+ sticker on the PSU; you'd need to open your case to see it. If the PSU has a little voltage switch on it, then it is NOT 80+.
The reason I ask about 80+ is because although they use a low temperature, they do run the PSU at 100% of what is on the label; cheap junk can't take that, and dies (which is why their manufacturers never submit them for testing).
If it has the PCIe power connector, it should be able to handle the Boost. Still, if only for the sake of longevity, you may wish to get a vanilla GTX650Ti. They still do pretty well.

By the voltage switch, I'm guessing you mean a little switch on the back that is red. It doesn't have that, nor does it have a sticker for 80+, only a green LED. I could be wrong but I'm still fairly noob at most of this. Here's a (quite blurry iPod) picture. Picture of PSU sticker.

Well, I can see that it has full range active PFC. That means the design isn't archaic. Acbel Polytech doesn't enjoy a stellar reputation, but again since this one is being made for HP, it probably doesn't suck. I would think you can run a GTX650Ti Boost on it.

>small question, so does that mean aswell a HD 7850 would run properly on this too?

Yes, it should. But, the Boost is generally the stronger card (in games, anyway). Choose the HD7850 only for bitmining or other GPGPU tasks for which you know the Kepler architecture performs poorly.
