I recently purchased a Cooler Master HAF 912 Series case. I bought this because my old case did not have a space for a 2.5" SSD. I took apart my old build (without taking pictures, of course...) and immediately began getting it set up in my new case. The first few times I was unable to get any hint of power when I pressed the power button, but after I unhooked the front panel LED's/switches, I was able to get some power. However, it only powers up for a split second (really not even 1 second) and then immediately shuts off. My motherboard is an MSI 970a-G46. It has a 4-phase power sequence(?) for the CPU (I know this by the blue LEDs on the board), and when I press the power button, all four of the LEDs light up before the computer shuts down.
I've tried the following troubleshooting methods:
Reseat 24-pin and 8-pin power cables that go to motherboard
Removed dedicated graphics card
Removed connections to HDD, SDD, and CD/DVD
Tried front panel connections both ways (can't really tell which is positive or negative)
Tried different power source (plugged tower in to another wall socket)
I'm really at a loss here. I know when I first built my computer about two years ago I had this same issue, but I think it ended up being the CD drive. I didn't take pictures last night of my connections, but I can definitely do so later today when I get home from work. I figured I would throw this out there for now to see if anybody had any ideas.
If anybody needs any more detail, please let me know.
Thank you so much in advance!
