Hello ,i will be changing my power supply that i have had for 3 years and i've been looking at many options i have. I ended up to the XFX ProSeries 650w core edition full wired for 80 euros(+shipping).
link here--->http://www.newegg.com/Product/Produc...82E16817207014

My current specs are:
i5 3570k 4.0GHz(will probably add a cooler and oc further)
Nvidia GTX 770 1333/1920
8GB RAM 1866MHz Corsair
Z77 Extreme4 Asrock
1 HDD and 6 fans(will add another hdd and an ssd)

Is this power supply good and should i buy it?

You should be fine with spending that same money on a PSU with 450-500W, and getting something more efficient, with potentially better warranty/fan/cabling/hardware, like this:

or this

Or just spend 15 euro less and get one of these:

Also, your link appears to be broken.

If buying from Europe, I usually recommend Super Flower Golden Green. They are excellent value, despite being high quality units with Gold efficiency. For a single GTX 770, the Golden Green HX 550W would be ideal. If you want to be able to run SLI, the HX 750W is 20-25 eur more.

That said, the XFX 650W is not a bad pick. I just feel that 80 euros is a bit too much for it.

i also +1 superflower. a slightly-bigger-than-needed PSU of goo dquality is a great investment that will both pay in the future (lower heat waste, lower bills) and gives you peace of mind - because of upgrade possibilities, quality components, and less constant load (thus longer life expectancy)

caseking.de is worth looking at

The XFX 550W should handle your system fine as well, it's much less expensive than the 650W unit
I thought of going for that but I wanna buy something that will be future proof and sustain power hungry components that I might buy in the future. Isn't the performance gap between the two worth it?

If you like. Personally I don't think the 100W gap is worth 20 euros... what I'd do is get the 550W unit, and if I bought components later that required more power, then I'd upgrade to 750W with proper SLI support, modularity and Gold efficiency

Seconded.
Even 450-500W are enough for an overclocked system with a 770-level graphics card.

When the time comes for you to get 300+ euro more of graphics card, and thus require at most another 200W of power, you can always get a new PSU at that time.
Realistically, the cost of components requiring you to go beyond 500W is so monumental, that it eclipses the cost of a power supply designed for this load.

In all likelihood, depending on how power hungry the overclock you run is, you're currently not even running into 400W peak power. Therefore even 550 is more than generous, and plenty to feed your CPU and a GK110 class card with a mild OC, for example.

I'm personally running a 500W enermax for my system with an MSI Gaming 770 (powerlimit maxed out), an overclocked 2500K, 32GB RAM, two SSDs, an HDD, a sound card, and five 120mm fans, as well as a number of USB devices. If the Enermax were to die, I'd probably go for the 480W bequiet with cable management - but then I don't plan on building an SLI system. But from my experience, SLI isn't worth the trouble anyway, except for very specific circumstances.

The question you need to ask yourself then is, will you ever get 2+ graphics cards. Because components of the same class go DOWN in power over time, not up. The only way you will NEED more than that psu is if you plan to get 2 graphics cards (or something super expensive) in the future.

Hmm, you would hope so... but I'm not sure we can draw such a trendline based on recent graphics cards. Sure, there's the GTX 750 Ti which is a great example of performance per watt ... but when you look at AMD, R9 280X which corresponds to 7950 in terms of price, consumes more power than 7970 (techpowerup). R9 290 consumes more power than 7970 GHz (techpowerup). And then we have the 290X which has power consumption in a completely different class compared to any single GPU in previous generations, although it is also quite a lot more expensive than the 7970 GHz or the 6970 before it.

But your point stands, 650W is enough for any single GPU.

So after your suggestions I ordered the 550w version. I think that in the future power consumption will drop as we can see from Maxwell architecture. One question though,if I were to get a 780ti would this PSU be OK?

Reference 780 Ti requires one 6-pin and one 8-pin connector, and the XFX 550W provides those (you can't connect a dual 8-pin card on it without adapters). Given that the XFX 550W is advertised as being capable of full power continuously, with peak power much higher than that, then I'm quite certain it can handle a 780 Ti.

In Anandtech Bench, a system with an overclocked CPU and a 780 Ti uses 370W from the wall while gaming, so actual power consumption is going to be closer to 320-330W.
