will this work in a mini itx case?

I have a phanteks evolv shift 2 mini itx tower this worked perfectly but I ended up getting a 750 watt I needed the extra power for my 3090

Are the cables cross compatible? If I’m replacing the 650w unit with the 750w version, can I just use the old cables?

If you are replacing it with the same PSU just higher wattage, then yes it is compatible. If it's a different PSU then no.

Ok i have a vbestlife itx computer case, aluminum alloy mini itx desktop computer case would it work in there?

The manufacturer is stating a 1U psu...that said, if your case is a little over 5" thick, the Dagger should fit.
