Chosen Solution

Dear Ifixit, I want to add 650 watt power supply to my HP pc because of the dedicated videocard Sapphire ATI 6970HD. Default power supply gives only 350 watt. How to convert my power supply to feed the HP motherboard. ATX to 6 +6 pin. Example site to get information: http://h30434.www3.hp.com/t5/Desktop-Har… I have the following cable, see attachment.

I want to do what livingnote says but how with my converter: If you do this yourself - cut the original HP plug off the original PSU so that your colors are on the right pins and then from the ATX PSU get an ATX header and wire grey to grey, black to black, blue to blue, green to green, just fine, but USE THE HP little plug you cut off the original HP PSU because indeed the pins are different from anything standard ATX. Colors are identical except for Purple which is 12VSTBY. If you don’t have 12VStby use a DC DC stepup converter or a wall wart PSU to get you started, wire + to purple, -/GND to black/PSU Ground and in you go. Plug it in, small green LED on motherboard should light, then you can turn on the main switch and board should fire up and give you a 515 fan not detected. Apart from that, looking good here. Gonna install chipset drivers next but that’s not my job anymore. :) Have fun, Lukas out. Update (04/23/2017)

Is this what he means, the red one (converter cable color) this is connected to the purple color cable wire from the default ATX connector?

Your pictures aren’t very good, I don’t know what I’m looking at there. But I think this would do the job for the PSU Let me know if this helps.

See image content:

But I don’t know if the picture with the connections are the right one for my motherboard to power up. And I don’t know how to read it. Like one of the 6 pins is the picture showing where the pins must be behind the connector or front of the connnector.

The 6 pins are separate. 2 times.

Look on ebay for “ATX 24pin to Motherboard 2-port 6pin Power Supply Cable F HP Z220 Z230 SFF 30cm” Wont let me add links

All 100%, thanks. Any idea how to eliminate the error 515 fan not detected - having to F1 creates a new problem (I’m using as a small home NAS away from everything). Any idea what signal / ground / voltage etc could do the job? Thanks in advance

I’ve seen a tutorial video on YouTube, but they’re not the greatest quality. But I can give you some of the research I did. This is the best video I found on the subject. https://youtu.be/Cid9TOu5XNU I believe the HP z200 has a 24 pin connector, the main reason you can’t upgrade the power supply is the four pin CPU power connector is proprietary. You’ll need one of these to sync the power supplies. Dual PSU adapter amazon.com/dp/B075VRMQ55/ref=cm_sw_r_cp_apa_i_mtumCbA4NQA49 And one of these to extended the GPU outside the case for larger graphics cards if you have the small form factor model. Pci Express riser cabel amazon.com/dp/B01N7D6401/ref=cm_sw_r_cp_apa_i_fvumCbJ818D9T Also I would only recommend this for one card because it is very power efficient, and I would even underclock it if you have the option. Gtx 1060, usually they come with molex to 6 pin adapters, if you have a floppy power cable or SATA power cables, two of those in the adapter will run the 1060. But I seriously recommend a GPU overclocking tool, tweak the power limit so that it doesn’t draw more than 120 Watts, if you go this route.
