EPS12v compatible with my EATX12v Mobo?

Hello all, I'm in the process of doing my first build and noticed that my power supply (EVGA 750G2) has an EPS12V cable, whereas my motherboard (Asus Sabertooth Z97 Mark 2) has only an EATX12v socket.

I notice that the EPS12v pins should be able to fit into the EATX12v socket, but for 4 of the pins that would mean inserting rounded holes into square pegs. Is there any way to confirm (short of calling Asus customer support, who may or may not be able to verify) whether it is okay to plug in all 8 (4+4)? I'm hesitant to do so if this may harm my motherboard, and I'm wondering whether I'd be better off just plugging in the 4 that definitely do fit? Would appreciate advice if someone is able to advise, thanks for your help!

My build:
CPU Intel Core i7-4790K 4.0GHz Quad-Core
Motherboard Asus SABERTOOTH Z97 MARK2 ATX LGA1150
Memory Crucial Ballistix Sport 16GB (2 x 8GB) DDR3-1600
Storage Samsung 840 EVO 250GB 2.5" SSD
Western Digital Caviar Blue 1TB 3.5" 7200RPM
Video Card Asus GeForce GTX 760 2GB DirectCU II
Case Cooler Master N600 Windowed ATX Mid Tower
Power Supply EVGA 750W ATX12V / EPS12V

    It's the same thing. Usually when together like that (all 8 pins) it's referred to as EPS but it is the same. Your 4+4 (CPU) connector goes there.

  3. It will fit. Round pegs (essentially square with 2 corners flattened) will fit in square holes on the motherboard. Square pegs won't fit in round holes, only square holes. So even if they don't all appear to match perfectly, it's actually 'keyed' in a way where it will only fit one direction (to prevent plugging it in backwards). Match up the square pegs to square holes and it will fit.

  4. Thanks so much for the quick responses! So to be certain, it sounds as though there's no potential of frying or harming your motherboard by placing the rounded holes into the square pegs (I know they fit, but want to confirm that the electronics will be okay as well)?

    I have the same problem as OP, but mine don't fit together, my MOBO ATX12V and PSU EPS12V don't have the same shaped pins.
