Hey guys!

So I'm going to buy a new PC soon and I'm chosing between 3 PSUs :
Supernova B2 750W and Corsair AX760I and non I, So Supernova B2 is bronze and has less outputs and its the cheapest of those 3.AX760 are Platinum and have more outputs and are more exspensive.But I don't need so many outputs so I'm leaning more on EVGA PSU but can you guys recommend me which one should I buy please?My system will be Gigabyte G1 gaming gtx 980 ti with i5 4690 non K (1080p).Gigabyte recommends minimum 600W for this card. I don't really know why is platinum better than bronze I don't know what does that do.

DO NOT buy a cheap psu.
OTOH such features such as platinum rating and modular ar not big advantages.
I suggest you go to newegg and filter on 750w power supplies.
Sort by price and look for the first tier 1 or 2 unit you can find. there will be many cheap units preceeding
At the moment it will be a XFX core edition 750w for $65 after rebate.

Not on the list, but look for Seasonic X750. At this time of year, I recall that there seem to be good buys on Seasonic.
I don't think you can go wrong with any Seasonic.

600w is fine for GTX980ti.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

There are others that may not be on such a subjective list.

Another trusted source for psu reviews is jonnyguru.com.

Here in my country the cheapest PSU of Tier 1 or 2 is EVGA B2 750W I think this PSU will be perfect 600W is minimum requierment for GTX 980 ti with two 8 pins connectors.(G1 gaming gigabyte card)but there are also other commponents in PC that will use some power so I think 750W is perfect :)

Don't ever go for a cheep psu coz when it fail or it damages it will destroy your mother board nd all connected gages to it lyk your processor your grafic card your ram nd off course your mother board.. Go for platinum one it doesn't fail so easy nd if it gets damage it will not damage your mother board nd connected gegs to it..
