Which connector is this and how do I connect the motherboard correctly (PC)?

Question

Hi guys.

I recently bought a PC.

Or an office computer (HP Elite desk)

With an i5 4570 and upgraded to a GTX 1070. My problem now is that the HP Elite desk case was too small, which is why I bought a gaming case (Endorfy Ventum 200 Argb). Now I have the problem that the power connection, ie the power switch plug on the case with which I turn on the PC, is completely different to any I have ever seen, and it is not compatible with the case either.

(The black one where 1 pin is missing in the middle.) The question now is what this type of power connection is called because I would like to buy an adapter so that I can use my case with it.

Then I plugged in the cable from the other PC, so that the PC was in the gaming case, but the cable was connected to the old one. Then I pressed the power button. The button briefly flashed white and then red. And I don't know how. (Only the CPU was connected, but with integrated graphics.)

My 450-watt power supply that came with my HP PC only has one 6-pin connector and one 4-pin and 8 SATA connectors, etc. Now I need a 6-pin connector for the GPU (with a 6-to-8-pin adapter) and one for the motherboard. Is there an adapter for this, from 1x 6-pin to 2x 6-pin, or do I need to buy a new power supply?

Here are a few more pictures.

So if I see it right, you really need some adapter at all. Correct me if I'm wrong.

Your new housing has separate plugs (second last image), you just have to put them right on the pins from the motherboard. Most of these pins don't care about polishing. Only, from my experience, HD LEDs (hard disk controller LEDs) can produce false ads if they are incorrectly plugged around (if they are permanently leaking instead of the usual charging torches). Where you can look at the plug of the old housing (yes marked on the sides, with +/-). Broken can't go, there's only low currents on it.

Note on my part: the HP Elitedesk signals a pre-boot check error from the motherboard with the red blind of the power button LED. So there's something he doesn't taste at all. So something that lets the boat finish completely before the BIOS Post Boot grabs and overrides the CPU (voltage error, RAM error, CPU error, timing error, hardware defect, etc.). I hope you've always cleanly discharged before you touch the components.

Now I need a 6 pin connector for the GPU (with 6 to 8 pin adapters)

If the graphics card has an 8pin connection, you will certainly not want to use an adapter from 6pin to 8pin.

6pin is designed up to 75W, 8pin to 150W. With such an adapter, you would call from a connection of the power supply that provides up to 75W to double if the graphics card is after. The wires of your power supply cables become correspondingly warm to the graphics card – and if it runs stupid, the fire extinguisher should be ready to handle next to the already open housing.

By the way… are you sure the graphics card is in the right PCIe-x16 slot?
Usually this is the upper slot that can be found directly below the CPU.
