I own a hp z400 full 24gb of ram 2 ssds and a 2 tb a 475 psu

If I was to put a RX 580 in word it work...
With a 4 pin molex to 8 pin pcie
Just a thought
Thanks
 

I've got a Z400 motherboard in my system right now. I don't own any RX-series Radeon GPUs to test with, but I see no reason why the RX 580 shouldn't work in your system. I know that the Dell Precision T3500 and other similar Precision models have some huge compatibility issues with Radeon GPUs, but I've never heard anything about issues with HP's older systems.

Your power supply should be fine at 475W, since the card only draws ~185W and the recommended wattage is 500W. I would be careful about using a Molex to 8-pin adapter though. They aren't inherently bad, but there are some sketchy, low quality ones out there, especially on eBay.

Also, what CPU do your have in your system? The LGA1366 socket has a wide variety of high performance quad-core and hexa-core CPU options ranging from $5 to $100+ used. The Z400 board has the X58 chipset, so overclocking unlocked Xeons is possible through software. Just a thought. If you're interested, let me know and I can try and help.

rule of thumb is to never use adapters

many people find out the hard way, dont be one of them

buy a proper psu with the pcie cables for the 580
 
I have tried it and now my HP is no longer working properly the graphic card ran at 73c on games and the hp cut off and rebooted it self i did turn it off then removed the card and put a gtx 1050ti back it in it where for a few days ran ok but then i loaded up some titles like bf1 gta v the forest and saw there to be very low fps drops...and im also having hard drive fails as well so i think its now a PSU issue as i said its testing to how far the hp can go but having a bad graphic connectors or card has now done something.

i do have another hp but wanted to see if what would happen and get some input from you guys and girls.
 

Very interesting, your issues don't seem like they're related to your PSU but you could certainly try getting another one, either an HP Z400 PSU or a standard ATX PSU. You will find that the Z400 PSU is proprietary though, and unless you buy another Z400 PSU, you'll either need to buy a 24-Pin adapter or make one yourself using a 24-Pin extender. It's a simple issue of two wires being a different voltage, so if you're able to do simple wiring safely, I can send you some links to guides on making the adapter.

Another issue you might consider is thermals. Your card might be running at 73*c because the Z400 doesn't have enough air flow. I don't actually own a whole Z400 system (my board is in a Phanteks case) but I know that OEM cases are generally worse for airflow than aftermarket enthusiast cases.

Just things to consider.
 
Workstation PSUs are usually multi rail. The power is divided between several different 12V. "circuit breakers". On an aftermarket single rail you can use adapters up to the full power limit. But on workstation PSUs if you draw more than the rated power from any cicuit it will shut down.
An example is My Dell T5500 875W PSU it has 5 separate 18Amp 12Volt rails. HP is probably similar.
The Z400 has a 4 pin CPU EPS connector. Aftermaket PSUs usually have a 4+4 there. You could use the 2 extra 12V. wires from that to convert the HP 24 pin to Z400 spec.
