Will an EPS12V PSU work fine with my current motherboard?

Hello,

I am replacing my power supply and I need to know if my current motherboard supports EPS12V. My motherboard is:
GA-970A-UD3 ( http://www.newegg.com/Product/Product.aspx?Item=N82E16813128519 )

and my current PSU is:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182069



Now, I am looking at these two power supplies to serve as both a replacement for the current one and to support future upgrades this year (thus the 1300w). The other reason I am replacing the power supply is because I've had it since 2010 and I suspect it's starting to go out on me (gfx slowing down, programs loading slower, higher cpu temp and so on.)


Rosewill LIGHTNING-1300 http://www.newegg.com/Product/Product.aspx?Item=N82E16817182063
EVGA SuperNOVA http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011

They both seems like decent choices, however the EVGA one says it has "2 x 4+4 Pin EPS12V" while the Rosewill option says "4+4-Pin ATX12V / EPS12V Connector".

So my questions are, will my motherboard support EPS12V connectors? Will either of these 2 power supplies work safely with my motherboard?

Thanks in advance!

PS. This seems more like a motherboard question so I decided to put it here.. I apologize in advance if I should have put this in another section!
 
They will both work fine on that board. All are standard ATX sizes.
However, getting over 1000w of power, for a system running on the 970 chipset seems a bit wasteful. I understand your desire to be "Future proof" but you should be fine with a quality 750w unit, and put the extra cash saved into an upgrade that would directly benefit you.

I haven't looked into the EPS part so I won't answer that, However, 1300 watts is going to be wasteful unless you pull about 50-60 percent of that all the time.

With an efficiency of 80 percent you'd pull 1560 watts from the wall were you to load that up. 1560 watts divided by 110 volts = 14.18 amps.

You'll be blowing circuit breakers at that point most likely.

Of course you probably wont use anywhere near that, but even then you need to draw 650 for that power supply to be running efficiently. Power supplies get the best efficiency (save you money) at 50-60 percent load.

Manufacturers like NVIDIA and ATI HUGELY overstate the needed wattage for their cards to run (unless you overclock). read some reviews on here of dual and triple setups and write down the power usage at full load, then go to the manufacturers websites and multiply their ratings anfd you'll see they are way over what they ACTUALLY need in real life.

I haven't completed my build yet but I planned on using two r9-290x and an intel i7-4790k. I won't have a full part list for a while as I'm still doing research. I hope that's enough to go on for now, if not I will probably have a list together in several days.

I see, well thanks for the input everyone! I was really worried that using an EPS12V connector on the ATX12V slot may cause damage or something. Anyway, I decided to go with this one and I'll be ordering it at the beginning of the month:
EVGA SuperNOVA 1050 GS ( 220-GS-1050-V1 ) http://www.amazon.com/dp/B00SOXNKAM/

and ps, sorry for the delayed response - I've been pretty busy lately.

Thanks!



edit / update: I installed the power supply today and it works great! Now I just need to slowly upgrade my system. Thanks again everyone!
