Installed seasonic m12ii 520W PSU and I get no signal for HDMI, Please help

ImPCnoob · Nov 10, 2016

I installed my new Seasonic m12ii 520W PSU and connected the connectors. It's not the HDMI cable since I troubleshooted it with my Xbox one. I must be missing a connector since my TV is receiving no signal from the HMDI. Before I removed the old PSU, the PC was running fine and the TV was receiving a signal from the HDMI.

I have a ASRock FM2A75 Pro4+ PCI Express 3.0 mother board with an AMD A10-6800K APU with Radeon HD Graphics 4.10 GHz processor. Along with 8.00 GB RAM. 64-bit Windows 10 OS and x64-based processor. Also a Allied ATX 300W switching power supply. My case is an NZXT Source 210 Blue with Window USB 3.0 Chassis.

Any suggestions would be great and much appreciated. Have a great day!

Please list full system spec, be specific. Get it? Bad joke, I know.

Hello.

You probably did not connect the PCI-E power connector? Look at this photo here:

If this isn't connected, you will have no HDMI signal.

Hmm, if you have no video card, then check the ATX connector here:

The correct cable looks like this:

It should be included with your modular power supply.

The reason I'm installing this PSU is so I can then Install my EVGA 3gb SC gtx 1060.

Natsukage :

I checked and I have both 4 pin connectors plugged in next to the processor and it is plugged into the PSU.

Does the computer still post? (beep) Does the hdd light still flash like it loads windows? If not, something is very wrong. Just to confirm...if you install your old PSU, do you have picture? If yes: you are missing a wire, or your new PSU is defect.

Natsukage :

Right before I uninstalled my old PSU I had the computer on and running and I had picture. Should I install the EVGA GeForce gtx 1060 and plug in the pci e and hdmi and see if I get picture? The fans for the cooler master on my processor turn on and the fan next to my mobo turns on and the PSU fan is on.

Well, you can always just install the GTX 1060 and check if you have picture with it. There's nothing to lose really. But I somehow doubt it will work.

Check all your cables once again. Compare them with your old PSU. Also, check if you did not dislodge a ram card in the process. Check if they are correctly in position.

If all seems right...just try your EVGA, and check out the picture?

If it doesn't work yet, try resetting your BIOS.

How do you reset BIOS?

Natsukage · Nov 10, 2016

To reset the bios, remove the small coin battery in the middle of your motherboard, while the computer is unplugged from the wall socket. And the switch is at OFF. Wait for at least 5 minutes, then re-insert the battery (+ is up) and test the pc again.

ImPCnoob :

Turn off the system, unplug it, press and hold the power button for three seconds to drain any remaining power, then open the case and remove the CMOS battery from the motherboard. It looks like a large watch battery and may be hiding under any expansion cards you may have installed. After five minutes, put the battery back in and turn the system on again. Thanks to the lack of CMOS power from removing the battery, the BIOS will have forgotten its settings and returned to factory defaults. I recommend setting the date and time in BIOS before booting into Windows.

Natsukage :

You didn't say to hold the power button to drain excess power. Skipping this step could result in OP getting shocked.

Natsukage · Nov 10, 2016

Shocked...? I've never been shocked by a PSU in 15 years...O_O This is 12V we're talking about. You can hold your hands on it and never feel a thing. But yeah, it's a good idea to drain excess power by flicking the power switch a few times. It also shortens the time you need to reset the bios.

Be sure to ground yourself correctly before attempting this! Touch any metallic part of your PC to prevent static discharge.

weberdarren97 · Nov 10, 2016

Natsukage :

In this case, it wouldn't be the PSU that would shock OP, but any capacitors on the motherboard that he might bump while trying to remove the battery. Everybody does this at least once so it's a good idea to drain extra power so they're not live if you do end up touching them.

I installed the gtx 1060 plugged the hdmi into it and still no picture. I reset the BIOS and tried it again still no picture. I installed the old PSU and plugged in the HDMI and still no picture. Before I removed the old PSU and installed the new one I had picture and could use google chrome and my pc ran fine.

Natsukage · Nov 11, 2016

Sadly, it seems like you either did a static discharge while removing the PSU, or your motherboard had issues before, and a single unplug would have killed it.

Before going to that conclusion though, can you test your HDMI and monitor elsewhere, or with another pc?

ImPCnoob · Nov 12, 2016

Natsukage :

Gladly it wasn't a static discharge and how do you prevent that for future reference? It was a simple fix, I took it to the computer shop in my area and the guy unplugged both 4GB RAM sticks, cleaned the ports, and reinserted them. I didn't see him do it but that's what he told me he did. I unplugged only one of them to help me get a better grip on the 24 pin Motherboard power plug to remove and insert it but did not unplug both 4GB RAM sticks. What are the next things I should upgrade on my PC for better FPS/Performance while gaming?
