What does it mean or what is it

It used to mean a lot more than it does today.

A lot of mobos have a 4+4 pin connector to provide additional power beyind the 20+4 pin power connection.
This is the EPS12V part of it. Most ATX PSUs include these today.

What about eps12v

EPS is a format for high end motherboards that have an additional 8 pins of mobo power.

Almost all ATX power supplies have these extra 8 pins.

These days, there is really no difference. EPS is classically marketed towards servers, but really, there is no difference in the wiring standards of either.
