Hi there,
Recently my AMD setup stopped working and I decided to upgrade. I got the new Intel processor, the motherboard, and RAM you see listed below. everything was fine with the previous build, specifically the power supply and gfx card im reusing on this build. the CPU was physically broken by a relative (honest mistake and not worth going into).
Anyways after a long irritating installation session, I thought everything wa tos good to go and try to turn on for the first time. Nothing happened, no fans are noises or anything. The only sign of life was an orange indicator LED where I had plugged the Ethernet cord in.
I'm typing this on my phone and I don't know how to bold but I'll point out in a separate paragraph. This motherboard requires not only the 8-pin CPU plug but an additional four pin plug which my 750 cx didn't have.
I figured I would try and beat the system as to avoid buying a new power supply. Thus, I appropriated the proper four pins that I needed from one of the additional PCI Express cables and plugged those in the mobo's cpu2 Port. I wouldn't be surprised if this is the problem but I made sure that it was 12 volts and ground where it needed to be (confirmed with multimeter.)
Thinking it was user error as I'm sure it still is, I unplugged and took out the power supply and made sure my modification hadn't screwed things up. I had cut some of the excess power cords that I wasn't needing as there wasn't much room in the case plus they were just unsightly. There are no stray wires or anything like that.
When I have the power supply removed and I shorted the green power pin to ground, it came on and the proper voltages were at all the appropriate pins, including five volts at the grey wire. However, when I did the same procedure with the other plugs still in (sketchy appropriated 4-pin CPU plug, and video card power plug, and SATA power cable), and just the main 24 pin ATX out, the power supply did not respond.
Figuring there was some kind of trickery or sense pin going on with either psu or mobo I decided to try using a 300w separate PSU, in addition to the 750, with the ground and power pin shorted, to supply the CPU 2 4-pin port on the motherboard. With this strategy, everything all of a sudden came on, but I got no post nor picture on my monitor. The LED light indicating CPU missing or failure was also lit. I suppose it should also be noted, and I find it strange that, everything turned on despite the smaller power supply's Main powerswitch in the off position. Additionally, when I remove the jumper from the ground to green power Pin, everything again turned off.
Trying to make the equation simpler, I tried without the external graphic card and use the onboard instead with the same result. I have tried clearing the CMOS, and I've tried reinstalling the RAM and only using one stick.
Lastly, I don't know if it's relevant but obviously I'm not the expert, I have essentially none of the front panel connectors plugged in. I put in my own switch for the power pins but the speaker pins, reset switch, and power and HDD LED pins remain unplugged.
I think I have included everything if not let me know. Kind of burnt out on the whole things for tonight so that's all I'm going to do for now. This is my first post I hope everything's aboveboard and within the guidelines.
Components:
-Corsair cx-750
-Intel Core i5-9600K Coffee Lake 6-Core 3.7 GHz (4.6 GHz Turbo) LGA 1151 (300 Series) 95W BX80684I59600K
-MSI MPG Z390 GAMING EDGE AC LGA 1151 (300 Series) Intel Z390
-Samsung 860 EVO 250GB
-CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000)
-EVGA GeForce GTX 1070 SC GAMING ACX 3.0
Edit: word choice, spelling errors and clarification. Sorry for the double post, don't know how that happened. I'm not very adept on the mobile platform and have been irritated in a hurry my apologies
