Topic: 1x GPU & 1x riser from single 6pin (Read 401 times)

Anyone else got a gpu and riser running from one 16awg 6pin connector?

Ah glad we got that clarified. Given that info and you pulling all of this from a single PSU I don't see an issue, though my personal rule of thumb with power-related things is don't plan to have load at 100% if you can help it to consider for manufacturing variances and spikes. Have a great day!

Edit: even if it's the official spec, you never know what corners manufacturers cut . I guess to be absolutely sure you can create a test environment for a cable at 12V/8A, if it handles that for a few minutes without getting uncomfortably hot then you should have enough overhead.

Theres a little confusion here as ive factored the gpu and riser combined to be 70-75w per card. From what ive read the technical "official" spec is 75w but the actual technical spec is around 175w based on wire gauge and load on each cable etc. But nevertheless i appreciate your replies and providing various other info

Apologies, definitely not trolling just trying to help. I might've misunderstood your first post thinking you mentioned the 6-pin's designed power draw rather than the GPU's power draw.

I still stand by what I said earlier though, feel free to correct me if you think these numbers are wrong. Source is wikipedia: https://en.wikipedia.org/wiki/PCI_Express#Power.

6-pin max designed power draw: 75W
GPU power draw (sourced from your post): 70-75W
PCI-E riser power draw: ~10W (I don't know the exact draw for a 1060 so to be on the safe side I'm using what the slot is designed for)

Given that, if you split the 6-pin your draw would be 80-85W, and the 6-pin is designed for 75W. Could you run this? Maybe. My opinion is I wouldn't. I'll leave the floor open for other opinions.

Ah, ok. The difference is your PSU can handle the power, but not that single cable. It's like a weakest link thing. Rather than splitting the 6-pin you want to have a completely separate 6 pin cable. What'll end up happening is if you try to draw more than the spec'd wattage from any cable it'll get hot and possibly start melting things. Or catch fire. I don't work with server PSUs and breakout boards, but maybe adding a cable is something you could do instead of getting a splitter and drawing more than a single cable is designed for.

So how comes the 1200w antminers use 10 6pin connectors and rarely have failures (considering the thousands of machines they have made).

Information is useful for calculations.

That's interesting because I thought GTX 1060s usually draw 120W power. ASUS doesn't provide power specs for this specific card (I even looked for a manual), so the closest reference I found was this: https://passionstation.wordpress.com/2016/11/22/meet-the-sweet-spot-graphic-card-asus-geforce-gtx-1060-dual%EF%BB%BF/.

Seems like the card can actually draw more than 75W at load (https://passionstation.files.wordpress.com/2016/11/specs.png) which is already risky for a single 6-pin. If I average out the 3 "avg" power draws I get pretty much 75W, so I wouldn't recommend splitting that 6-pin.

Not really sure why I need to say what the card is when i know the power consumption of each card and the system consumption at idle aswell. All 5 cards are Asus Dual 1060 6Gb's. Also the whole rig is running from a HP 750w Platinum Server psu with sidehack breakout board.

What GPU? Regardless, unless it's a potato you're going to get a bunch of no's.

I want to tidy up the cables on my hobby rig and just checking that it would be safe to use a 6pin splitter so i can run one card and one riser (one 6pin socket on each totalling 70-75w) from one 6pin cable.

Thanks.
