No power, nothing labeled on motherboard, any ideas?

Millgo47 · May 29, 2014

I just installed a new power supply CX750
I thought I rehooked everything back the way I had it but when I hit the power switch I get nothing.
My tower is HAF 932 full tower.
My mother board is HP IPISB-CH2 (Chicago)

Not sure if the pictures help.

Hi. You sent pictures of everything but the important stuff. Make sure the 24 pin ATX connector is snuggly plugged in an clipped. Same with the 8 Pin CPU connection. Most times that is actually 2 four pin connectors and can be a bit difficult to get plugged in. They are identified by yellow and black wires. I think the PCIe connectors are too, but they are marked as PCIe.

And make sure the front panel power switch, et al are attached correctly to the front panel header on the mobo. Here's a diagram: http://www.findlaptopdriver.com/uplds/ipisb-ch2.gif

I uploaded the pictures you asked all the wiring seems tight

Sorry. I had to enlarge them. The connections look good. AS for the front panel stuff, you shouldn't have had to unplug that for a PSU changeout, so shouldn't be an issue. They looked alright from what I could see. Make sure the switch on the back of the PSU is on.

Thanks you were right, it was the 8 Pin CPU connection it was just a bit loose and not fully clipped, I thought I triple checked, apparently not haha, Thanks for your help; appreciate it.

Yeah, those things are difficult. The reason I made that last suggestion is because I have been working inside one then went to start it and nothing. I checked everything, but couldn't find anything out of order. I just happened to check the switch on the back of the PSU and I had inadvertantly shut it off while moving the computer.
