Hi! This is my first time building a PC and I have a question in regards to a PSU and the compatibility of its connectors with motherboard connectors.

CORSAIR RM Series RM650 650W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Asus Z97-A

--Now my first area of confusion is in regards to the PSU as it is labeled as "ATX12V v2.31 and EPS 2.92" What does this actually mean? Is this just a fancy description for being ATX compatible or is it something different?

--My second question is in regards to the connectors. The mobo specs state that it needs a main 24-pin EATX connector whereas the CPU needs an 8-pin ATX12V connector. The PSU has an ATX connector, which I assume is the 24-pin connector, and an EPS connector which is probably for the CPU. What exactly is the difference between EATX, ATX12V, and EPS connectors? Are they just different names for the exact same cables/connectors?



So will this PSU and mobo work together and am I just making something simple more difficult than necessary? Thanks for your help!
 
Solution
You are over complicating things. The PSU can only be incompatible with the case because of its dimensions. Unless you have a PSU from 10 years ago you'll be fine. You can only plug things where they are meant to be plugged when talking about PSUs and motherboards.

Quick answer -> Yes, that PSU works fine with your motherboard.

ATX versions tell you what version of the ATX spec it is compliant with, it doesn't really impact you.

As for the connectors, its marketing people being dumb. The 24 pin connector is the main ATX connector, the 8 pin CPU connector is an EPS connect, a 4 pin CPU connector is an ATX12V connector. Its just people confusing acronyms.
