The 7750 is the strongest card that is powered entirely by the pci-e x16 slot.
Your psu should be good.

If, by chance your psu is of very bad quality, you might see some artifacts or other symptoms, but no harm will be done. Try it.

If you find you need/want a stronger psu, the corsair cx 430 is a very good budget unit that is often on sale.

A psu calculator is deadly accurate...... Assuming you can give it accurate information.
Unfortunately, we can't. Who knows what capacitor ageing factor to use?
Or more simply, what graphics card might you use in the future.

A reasonable approach is to base your psu on your graphics configuration which consumes the most power. The other parts difer little.
I use this guide:

It is not wrong to overprovision a bit. A psu will only use the wattage demanded of it, regardless of it's maximum rating.

Whatever you do, buy only a good quality psu. Here is one list for that:

I've often recommended the HD 7750 for those with a 300 watt OEM power supply and I've never heard of any failures. It should work.
