Can't remove power supply, instructions for regular G5 don't work

I tried to follow the regular G5 and the repair guide says you just slip the power supply out after unscrewing it, but mine seems firmly fixed by something I can't see. Any guidance?

Update (06/09/2018)

Seems to me like this row of weird screws is holding the power supply in. I thought I had the right Torx screw for it but apparently not. Any ideas?

@sunsetblow Yes, you have to remove the power supply bus bar screws to free this up. According to the manual those are T-10 screws.
