I would be having these specs:

GIGABYTE GV-R777OC-1GD V2.0 HD 7770 1GB
Intel Core I5 2320 3.0GHz Quad 6mb cache
Asrock B75 Pro3-M 1155 Micro ATX 4 x DDR3 1600 Intel B75
4GB RAM DDR3
1280 x 1024 monitor
Windows 7 64 bit

I'm thinking about the XFX Pro 450w

Obviously I'd like to spend as little as possible but I want a trusted PSU

Great PSu and more than sufficient for your PC. Where are you buying?

Your current choice will work fine, however, so will a Corsair CX430V2.

The XFX PSUs are great price to performance PSUs in the EU; hard to beat the value/watt with a 5 year warranty and made by Seasonic.

But the GPU requires 450w atleast that's what the site says

It's an 80 watt card, they reccomend 450 watts for the system with the card
You could use an Antec 380 and have plenty of power overhead

Corsair Builder CX500 €52
Corsair Builder CX430 €43
XFX Pro 450W V2 €52
Which one to pick :o 
If you really think the 430w Corsair one is good enough I will just get that one, but would I get a performance boost whatsoever with the others?

No performance boost for the more expensive PSUs and the CX430 is definitely sufficient for your PC. Check prices on the Antec VP450 and the Enermax NAXN82+ model ENP450AWT B. Choose the least expensive of those and you'll be good. The CX430 is a great deal in the US, too; can usually be bought for $20-25 after a mail-in-rebate.

I would go for an OCZ PSU. For the equivalent price of a Corsair TX650 or the Antec HCG 620, you can get an OCZ Fatal1ty PSU with more power with the same power efficiency.

Then again, it is your choice to pick.

The lowest rated Fatality PSU the 550W since the 400W was discontinued. Not to mention that not all of the Fatality PSUs are of the same quality; it's a mixed bag. If going that route, then I'd stick with the Corsair Enthusiast but that is not what the OP is looking for....OP is looking for an inexpensive but decent quality PSU. In the OCZ lines the ModXstream PSUs best fit that description. The OCZ ModXstream 400W has been discontinued and the 500W will be more expensive than the CX430.

As the previous posters have stated, you won't even use 430w of power, it's only recommended to get a 400w PSU for your system as a whole, not just your GPU.

Your GPU uses 80w, your CPU uses 95w, and your other components etc will most likely use around 50w at most, that's a total power draw of 225w.

Realistically speaking, you'll only use around 180w maximum so the earlier recommendation of an Antec Earthwatts 380w PSU is sufficient as well.

TL;DR - You only need 350-400w for your system, just make sure you choose a PSU that's from a reliable company as the ones listed above.
