Hello, I wanted to know is it worth to pay 4 more euros for 650W PSU even if 550W is enough for me, is it better that I have less % load on my PSU and is there any differenece between these two PSU's, It looks like 650W one has 4x6pin but official page says only 6pin but newegg says 6+2pin connectors, so I'm not sure.

With that system, and that price difference, get the 650 every time.

Its got the right amount of headroom, the right amount of upgrade ability, the right cables (4x 6+2pin PCIE) and the right price. Perfect.

The difference in price and wattage lead to one simple answer: Get the 650.

Most PSUs are only efficient at relatively high load %, but as the difference is only 100 watts, that % will not be massively different and therefore will not have any noticeable negative effect.

For 4 euros, you may as well get the bigger one that would allow for more future upgrades.

As for the cables, it would be extremely strange if a 650watt Gold rated unit from a solid manufacturer like XFX didnt have 6+2pin PCI-E cables, and every site Ive found it on say it does.

I don't see why not.4euros is not that much and if one you decide to upgrade to a more powerful gpu you won't have any problems or limitations. They are solid psu, so yes buy the 650W even if you don't need it.The difference is very small. As for the pins just check images, many companies misspec their products. Or even better a review at a site.

4 more euros, not four time more, the 550w is 70euros, and the 650w is 74euros.
And right now I have
i5 4690(non-k)
asrock h97 pro4 motherboard
2x4gb crucial ballistix sport 1600mhz cl9 ram
and i'm thinking of buying gtx 970 (maybe asus strix)
so I don't think i will be upgrading this pc, I would probably buy new one after few years.
