wow, much confused post...
New Build not powering up!!!
On my Old MSI P-35 Platinum, it had 8 or. 9 Mobo stand screws. (Correct name escapes me) This new B85 has only 6, are these universal in size, I did not see any of these with the new Mobo, are they usually included? I'll look again.
I was careful, counted only 6 Mobo holes and aligned th up with the screws.
I ended up using the Intel stock cooler, so there is no retaining bracket on the bottom from
an after market cooler making contact with case.
Your old MSI sounds like an ATX size while your new B85 (Asus??) is micro-ATX size. So the smaller board uses less standoffs. Only use the correct amount of standoffs.
I went to Fry's and bought a CoolerMaster 550 PSU, I was going to try that first, would that cause any problems? (24 ATX PWR, & 4+4 CPU)
Shouldn't be a problem.
