The 10mv3at - it's the ATX 8-pin power connector (12V). It needs a 8-pin or a 4+4 pin connector.
The 25gudcz is a PCIe connector 6+2 pin - for graphics cards that need the extra power.
The ztxj44 is what you need for ATX (4+4 pin).
Every screw hole of the board should have a corresponding standoff (an extra standoff would short the board). 2 standoffs are not enough.
But since you are here, I would firstly test the board outside the case, with a minimum configuration, just to make sure it does work.
Put it on the board's box or a similar non conducting surface, install the CPU, CPU fan, one RAM stick, graphics card, keyboard and mouse and see if it does boot.
The mobo is supposed to rest on standoffs for avoiding a short with the case.
