My sytsem:

CPU: i5-4440 Cpu 3.10GHz
Ram: 8,00GB Single-Channel DDR3 @ 799MHz
System: 64- bit, Windows 10
GPU: 1060 6gb
SSD: 111GB KINGSTON SV300S37A120G (SSD)
Motherboard: ASUSTeK COMPUTER INC. H81M-K
GPU:Asus Geforce gtx 1060 OC6gb
Optical Drives: TSSTcorp CDDVDW SH-224DB

So how many watts will it use .And my GPU isnt OC
Thanks for the answers!

Less than 84W (CPU) + less than 150W (GPU) + less than 100W (other components) = Less than 334W total.

A PSU rated at 450W is more than enough. Good price/performance PSU would be the Corsair CX450M.

If a ~550W or so PSU is cheaper (or about the same price), you can go ahead with that for more headroom in future upgrades and better efficiency at 50% load. Good price/performance PSUs in the ~550W or so range are the Seasonic M12II-520 EVO, or the Corsair CX550M, or (if budget/price is good) the Seasonic G-550.

So if youre correct than a 250 psu wouldnt be enough for the 1060 but would be enough for the 750?

It depends on your PSU quality (built, components, protection, and efficiency). A mediocre PSU should never be used at full load (much less a bad-quality PSU should never be used at all - else, risk damaging your components). Generally (not specifically), a rig built around a GTX 750 is "recommended" to have a PSU wattage of 350W (http://www.realhardtechx.com/index_archivos/Page362.htm). This is taking into account the PSU you have is mediocre (or less than mediocre) quality.

Using a no-name 250W PSU is very risky. They don't have protection such as overcurrent/overvoltage/undervoltage, and the like. It is highly likely it doesn't provide 250W at all. Look at the +12V rails, as the +12V powers most of the PC components. Usually, a 250W PSU could be just around ~180W-200W or so at such rail.

No, 250W would not be enough. Even if it has a max draw of 240, say, you want headroom in case of small inaccuracies in calculation , as well as keeping within the max. effiiency range of the PSU.
I usually want my max. power draw to be around 70-80% of the PSU's rated power. To find this, divide the power draw you have calculated by 0.75. The result you get will be around the power PSU you will want to get.

So the amount of the psu should be displayed somewhere like this? (not my psu):

Yes, that's correct. Pay close attention on the +12V rail (the total amperes and/or the total wattage).

In your photo example, the Power Man IP-P300AJ3-1 power supply (a "300W" PSU), only provides 18A at the +12V rail (or equal to 216W).

So which one should I choose ?:

The Seasonic S12II-520 is significantly better than the Corsair VS550 (which is already discontinued due to its poor quality).

HOWEVER, it is better to get the Seasonic M12II-520 EVO version, or, best, the Seasonic G-550 version as I have read before that the S12II series have some problems with Haswell (4th-gen CPU such as your i5-4440) Intel sleep state enabled. See: https://www.bit-tech.net/news/2013/05/14/seasonic-confirms-list-of-haswell-compatibl/1

Some M12II series models does support such feature and is fully modular (so you'll only use the cables you need and not have to hide/clutter the inside of your case with unnecessary cables that will restrict airflow). The G Series, are fully compatible with Haswell CPU's sleep state feature, are semi-modular, and have better build compared to the M12II and S12II series.

Given your system specs listed in your opening post and considering the budget based on your latest post (the Seasonic S12II at EUR 57,50 and the Corsair VS550 at EUR 44,90), these are my recommended PSUs:

Corsair CX450M (EUR 51,90): https://www.amazon.de/Corsair-CP-9020101-EU-CX450M-Teil-Modular-Netzteil/dp/B019NWTCEA/ref=sr_1_1?ie=UTF8&qid=1497468178&sr=8-1&keywords=CX450M

Corsair CX550M (EUR 67,99): https://www.amazon.de/Corsair-CP-9020102-EU-CX550M-Teil-Modular-Netzteil/dp/B019NWRUXK/ref=sr_1_2?ie=UTF8&qid=1497468178&sr=8-2&keywords=CX450M

Seasonic M12II-520 (EUR 71,94): https://www.amazon.de/Seasonic-M12II-520-Stromversorgung-520-ATX22/dp/B0038T0V8Q/ref=sr_1_1?ie=UTF8&qid=1497468093&sr=8-1&keywords=m12II

Seasonic G-550 (EUR 80,56): https://www.amazon.de/Seasonic-SSR-550RM-Active-G-550-PC-Netzteil/dp/B00918MEZG/ref=sr_1_1?ie=UTF8&qid=1497468115&sr=8-1&keywords=G-550+seasonic

Just select from any of the above good-quality PSU models, based on the budget you have.

Newegg has a wattage calculator. Not entirely accurate, but it gives you a good idea. It says 399 watts. Now it doesn't let you put in exact parts, so it is probably off some. But a PSU over 500 watts will be safe. But the price difference between a 500 and 600 is negligible, I would go ahead and get the 600 for future upgrades.
