I was a beta tester for this line of PSU. Only problem I had was that they sent me a 750w while I don't own a rig that will take a 750w

I told them but they just said do what you can do ?
I thought of rebuilding my q9450 rig but never quite made it. I wrote them back asking where I could send it back to them but they never told me ???
No label on it other than a mix of beta id numbers with 750 embedded in them.
