Hp z420 problems

[MrAnchovies]

Hey, soo I've got some issues with my new/old hp z420 workstation. I just bought it and slapped in my powercolor hd 7970 to see whats up with it. And no post/display I can't tell which. The graphics card wants an 8 pin and a 6 pin pcie power, and only 2 6 pins are plugged in. I thought it would atleast have display. 

 

I have another card I'm going to try, it doesnt need pcie power cables so it should work. 

 

I currently don't know what version anything is, so if you have suggestions that would be great. 

 

Thank you.

The GPU needs all the required power cables plugged in order to work.

Ok I need to upgrade the psu I think, because my nvs 285 fires up fine. Thank you kameshss, so what psu should I get because the motherboard seems to have like a 18 pin power and an 8 pin cpu power

I found some 24 pin to 18 pin converters on Amazon. But not sure how reliable they're. I think it'll work.

 

Research on this https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/HP-z420-motherboard-18-pin-layout/td-p/5835021

 

Also, Does your current PSU have molex connectors? Because, there are converters for Molex to PCIe power like this https://www.amazon.com/Cable-Matters-2-Pack-8-Pin-Molex/dp/B01DV1Z428/ref=sr_1_3?ie=UTF8&qid=1520059990&sr=8-3&keywords=molex+to+pcie

 

Check it out first.

My power supply has no molex so I need a new power supply, I assume.

That shit is proprietary boiiii , but in all seriousness idk if the adapter will work and I would really just suggest to get a different gpu with two 6 pins or even get adapters from a 6 pin to 8 pin rather than a whole new psu.

Thats what i was just looking into

Ok I ordered a 6 pin to 8 pin adapter I'll tell you guys how it worked

Hi got a z420 as well. Gtx 1080ti connected. I use a molex to 8 pin which has worked fine around 4 years. My 780 worked fine on it as well.  I use it usually for heavy rendering sessions. Sometimes a few days up to a week or so.

I received the adapter and it seems to be working fine 

 

Thanks for the help

 

But I've run into another issue where only 3 of my sata ports work the 2 sata III and the top sata II port

I don't know if you guys can help out with that but I figured I'd try
