I may be wrong or not.
Please help.
You also need to include your i5 + your RAM + the motherboard + HDD's and ODD's etc. It all add's up.

It's pretty simple mate.

You'll need a new PSU, and most likely a new case as well in order to upgrade to a mid/high end card.

That doesn't mean your PSU can handle it. So yours is 350 Watt. It has to handle everything - your CPU (95 watts for an I5 750), graphics card, + everything else. Just your processor and graphics card use up 95+212 = 307 watts. Then there is your Motherboard, RAM, fans, disk drives, etc. etc. The 350 watts isn't adequate. I don't think it is even adequate for what you have now.

Go by the graphics card manufacturer's recommendations. For the 5770 it is at least 450 Watts. Plus your power supply needs to have a 75W 6-pin PCI Express® power connector:

Dells suck as far as upgradability. Their MB are proprietary, their cases pretty inadequate for cooling and not standard ATX, and their Power supplies are always barely enough for the system as ordered.

The 5770 is more than ok, it is probably the best mid-range card out there.

I am a complete NOOB at finding what to buy for computers (But i can find good graphics cards)
So, what PSU upgrade should i get?

At least 450W Antec, OCZ, Seasonic or Corsair

Look at newegg - they usually have one of these on sale.

It will probably have multiple 12 volt rails each capable of 300W. You'll want the separate PCI-E power connector for the card to be on a different rail than your CPU etc.

You will probably need to beef up the cooling of your case - more or more powerful fans.

I agree with GeneO on this as well. I would go a bit higher to 500 though. Even if a 450 is enough to handle the system, PSU's degrade a little over time and its not good to run the PSU at 100% capacity. Allow for enough head room and get either a better fan than your case has or an additional fan. You will need more cooling due to a powerful graphics card being in the case.

Here is a good site for adding up all your components so you can see what your minimum and suggested PSU power would be.

And another resource for cooling:

I'd look for something in the ~600W range.

Like this one:

SlackerITGuy +1 on that, I would also only consider a modular if it's still affordable for the OP. When they out grow the Dell and case the old PSU can go in and the new PSU and GPU can go in the new build.
