Should I use molex to 6 pin?

[Royal Chicken]

I have a 2014 workstation that I want to put in something like an RTX 2080 Super which needs a 8+6 pin. I already use a dual 6 pin to and 8 pin for my rx 570 right now. The PSU in the system is about 900w so is it safe to use a molex to 6 pin?

The PSU isn't the problem. The adapter is. Most of them are shittily-built. Some are so shittily-built that they can damage components or catch fire.

 

Honestly, thinking about it more, a 900W PSU that doesn't have enough PCI-E power connectors to handle an 8+6...what unit do you have, exactly?

oh hell no, those adapters are very prone to catching fire.

 

If it's a Dell Precision or HP z-series, both companies offer safe and reliable power supply adapter cables that don't involve Molex.

No nop nope. Those adapters are a hazard.

 

What workstation fo you have and why does it sound like a hp z620?

I have an HP z640. Very proprietary psu so I can't upgrade.

Is there a distribution board inside those, like Dell uses in the 2011-3 Precision workstations? If so, there's probably a PCIe power cable available that your machine is missing; you just have to find the part number.

Ah ok easy.

 

So get the OFFICIAL hp 6 pin to 8 pin pcie adapters and you'll be fine. The 6 pins carry 150w of power but arent 8 pin so hp could charge more for an adapter

A generic often doesnt have proper quality wire

Are you saying that the 6 pins for this specific PSU carry 150w instead of the industry standard 75w? Sorry I didn't fully understand what you said.

No there isn't. The only GPU power cables are the dual 6 pins.

Yes

 

Hp did it for all their z200, 400 and 600 boxes (800's depended on config).

 

The adapter was 95 new. Basically a way to avoid users getting too good after market gpu's and prevent them from adding more powerfull ones without paying hp tax

 

Also you're like the 7th person asking this question this week alone. Is there likr a sudden dump of these

That's very odd, thanks a lot!

It's typical enterprise workstation bs. Most companies that buy these in bulk see an extra hundred or 2 on a 5k starting price machine as little extra cost. Whilst for hp it's probably 98% pure profit on those adapters.
