I was wondering - did you need to do anything special to install the 850W Corsair in your m9650f? Reason I ask, I'm trying to install a 750W Corsair in my e9150t system. In summary, installing new Corsair 750W power supply in new HP PC causes PC to fail to POST. I've built several PC's over the years, never hit this type of brick wall.
The details:
1. We purchased this computer HP e9150t
2. The HP PC has been running for several days as burn in, working fine.
3. So that we had enough overhead for larger video card (video card was not yet installed - everything was stock on the HP except for the PSU) we were looking to swap out the 460W power supply with this 750W power supply, CMPSU-750TX. We have this power supply in our current Dell PC, works fine. We just pulled it to install in the new PC.
4. After the Corsair PS is connected to the HP the HP fails to boot. The cooling fan on back plate spins up, the power indicators on the PC light up but no other noticable progress - fails to POST.
5. To eliminate any chance of one of the peripherals causing a problem we connected PS to only the 24 and 4 pin connectors on motherboard and booted, no change in response. The attached monitor didn't even acknowledge any signal from PC.
6. To confirm that HP didn't suddenly hit the wall and crap out on us during the PS upgrade we connected the original PS to the HP (only 24 and 4 pin connectors), unit hit POST (monitor registered signal).
7. Connected Corsair back to HP, same non-responsiveness.
8. Connected original HP PS and assembled unit, works fine.
9. Put Corsair back into Dell, Dell works fine.
10. HP just doesn't seem to like the Corsair 750TX power supply
So, what I'm trying to understand is why a "better" PS (better wattage) would fail to boot up in the new HP. Any suggestions or anyone have any idea on what may be causing the conflict? PS - we did not install the new video card yet, everything in HP was stock other than the swap out of the power supply.
