Looking for a good PSU for my first pc

hello, I'm saving up money to build my first computer.

This computer is made for gaming purposes, and so I REALLY want to be sure nothing is wrong with it, and since I understand that a PSU truly is the heart of a computer, I want to ask the help of some expert here.

I have budget limits, I really wouldn't want to go over €80 for the PSU.

this is my build

- CPU: AMD FX 8350 (not going to overclock it, for now) (not bought yet)
- GPU: VTX3D AMD RADEON HD 7850 2 GB
- MOBO: Asrock 990FX Extreme3
- RAM: 2X 1600MHZ 4 GB Corsair Vengeance
- 1 X 5400 RPM SATA 500 GB HDD
- 1 X 128 GB Samsung SSD (not bought yet, but going to do in the near future)

I have no interest on adding anything else to this build for now, so, this is the question:

What PSU do I require to safely run this build at FULL LOAD with no worries? 500W? 600W? Also what CPU would YOU, dear reader, suggest?

thanks in advance for the help.

A 600W from any good reliable brand is enough (xfx, antec, corsair, coolermaster) you can get a modular 80+ certefied for around 50 60€.
Also the FX8350 is a good cpu, but i sugest you get an aftermarket cooler, since the stock one is not so good. (a bit loud)
CM coolers are good and cost around 25 30€.
Altough you can always buy the cooler later, if you can handle the noise.

I really have no intention of upgrading in the near or far future this build (matters of 2-3 years), and I'm honestly worried about bills with a 750W PSU.

Plus, but I can get over this, I buy everything from Amazon, since I know no other place where to buy stuff, I know no other reliable site.

a 750 watt doesent mean it will consume 750 watt all the time.it consumes as much as it is drawn from it.it can output 750.
if yoy are browsing the internet you might only consume 200 watts if you are gaming and your computer is on a 100 % load it will consume 500 watt or even more depending on the hardware.
lets say 750 watt is 100% of the power supply on 50% load you have the maximum eficiency.which is 375 watts on your system.if your system goes 500 watts the eficiency will drop.with a 80 plus it will never drop under 80 %.why i sudgested 750 is that if you are gaming your system will consume near 500 watts if you had a 600 watts psu that whould be 90 % load on the psu.the eficiency will drop.
now what is the eficiency.
your power outlet isgives you 220 volt ac your power supply converts it to 12 3.3 and 5 volt dc.in this prosess there is a loss in wattage.if your power supply is a 600 watt and has a 80 plus if you put it on a 100% load you will consume 720 watt the 120 wats are lost in the conversion.if you ceep it in a 50% load wich can go up to 87% eficiency the loss whould be only 75 watts 45 watts in defecence.
this is the reason why i sudgested you a 750 watt bronze so you can ceep the load on the psu under 80 %at most times getting the best eficiency and saving money.in a year the loss is equal to a psu.or more.
i use newegg to find products at the price point where you will buy it from is you concern:)

I see, but even if, the prices are a little overboard:

and I don't think I'll be able to find it any cheaper than that.

I'd go with a 550 - 600 watt bronze 80+ from seasonic or xfx. Unless you are gaming a lot (and i mean really a lot) and electricity is oddly high where you live, the extra cost usually won't offset the savings from the electricity bill.

My plan is exactly to use it for Gaming (Battlefield 4 Ultra with no antialiasing), to succeed this build:

Intel Core I5 430M
ATI Mobility Radeon 5470
2X2GB 10XXMHZ DDR3 Memory
320 5400RPM Notebook HDD

And I was thinking about buying an XFX PRO 550W, but maybe a Corsair GS600 is better? I don't know.

PS: Yeah, electricity is oddly high, but I was suggested that an AMD FX 8350 was way better than a Core I5 3570K, so I went to my actual build.
