Im trying to buy a case and a psu, but I dont know what size of a psu goes into the case I have selected out.

PSU needs to be atleast 550Watts, with 2x6 pin connectors for the videocard, graphics card is going to be Gigabyte GTX 560 TI OC.

Other specs:

i5 750 quad core processor

8GB DDR3 RAM

The selected case: http://www.1a.ee/arvutikomponendid_vorgutooted/korpused_jahutid/arvuti_korpused/mars_gaming_mc0_matx_black_tacmarsmc0

If you could, I would be so happy. places to look at: (I cant afford any other place since there will be pricy shipping fees)

Minimum is 500, and 550 is recommended. I dont want to have any problems in the future when I am going to max out the card to its potential limit, so I need 550 i think.

would this go, if 2.4 atx is the standard size?

Its cheaper, and if it fits, I need that. I dont want to spend lots of money

Doing the math, you're not really ever going to need more than 300-400 watts with that setup.

No you don't. That is only what they recommend due to them wanting to protect themselves since they have no idea aobut how good or bad your PSU is or the rest of your build. What is recommended is not what is really needed since you can figure out how much power you really need.

You would be lucky to need more than 300W. Keep in mind this is from the wall so the system is using less than what is shown here.

But it has nothing out on it so for we all know it could be a train wreck that will damage parts, could go boom at anytime, and could be stable as quick sand. You shouldn't cheap out on the PSU and especially you shouldn't buy units that don't have any information out on them.

The CXM has the best bang for your buck. Its only a few dollars more than the S12II and M12II and a few other units which seem to only known units but its better than them.

Looking at the site you are using now you can get a 450W CXM for about 60.

are you sure the pc will boot afterwards up with 450 watts?

also it has only 1x 6 pin connector i think

I am afraid it wont boot up. on old forums people say 500 watts is needed for that card, especially when you have a dual fan card.

The card is also overclocked, what about that?

also I found this about the psu I wanted: http://www.aerocool.com.tw/en/psu/value-series/vp-550w

Yes, you will be using less than ~300W. See above.

also it has only 1x 6 pin connector i think

It has 2 2+6 pins.

Maybe a few watts difference, it is still plenty of wattage.

I am afraid it wont boot up. on old forums people say 500 watts is needed for that card, especially when you have a dual fan card.

Not sure how to say this but those less than bright to say the least. The fan has NOTHING to do with how much power a card uses, they are going by recommended wattage which is completely wrong since its not accurate, see the anandtech link.

also I found this about the psu I wanted: http://www.aerocool.com.tw/en/psu/value-series/vp-550w

Its a a very bad choice. See what I wrote about it above. You wouldn't want it.

It says: PCI-E 1 x 6 + 2 PIN - it means 2x 6 pin connectors? just making sure I understand correctly

By 2x 6 pin I mean like, 2 6 pin connectors
