You should be OK, in one system the card was tested in, it used just under 190 watts real power at load for the full system. Your computer should be using that or less.

Is the power supply 350 watt or 300? A PSU rated at 300 is probably good for 250, which should be OK, Delta is a good brand so your PSU should be putting out close to it's rated power.

Got it, you should be OK with that power supply. 300 is the normal wattage the PSU can put out without breaking a sweat, your system will need under 200.

If you get a radeon 7750 you don't have to worry about the power supply because it gets all it's power from the PCIE slot.

But where does the PCIE slot get it's power from?

If he had a 175 watt PSU in the system which many small office PCs do, would not be a good idea to run that card in it.

Yes, the slot will power the card, but a 70 watt card will need a more powerful power supply to run it than a 20 watt card.

Good point but he doesn't have a 175 watt PSU his is a 350watt PSU from Delta so it will be enough for a 7750.

Right, what you wrote though made it seem like the power supply did not matter, I wanted to clarify things a bit. The fact that the power supply is good for that card is the main point, not the fact that the card does not need external power.
