power supply — 6-pin PCIe cable for 8-pin PCIe graphics card (GTX 1070 for HP Z820)?

Forgive me, if this has been asked before: While researching I found countless similar threads, yet virtually all of them involved a weaker power supply unit (PSU) than the one I am using. So, just to make sure…
Can anybody help me understand, if it’s alright (and riskless) to power my GTX 1070 graphics card (which has a 8-pin PCIe power connector) using a 6-pin PCIe cable (and an adapter)? Here’s what’s unclear to me:
- I understand that the 8-pin connectors basically tell the card that it’s possible to draw up to 150W from the PSU.
So, combining this with the 75W from the PCIe port means that the graphics card will want to get up to 225W from the PSU. I know for sure that my PSU itself can handle that, as currently, there’s a card plugged into the same PCIe port that is connected using two 6-pin connectors. So, provided I just substitute the old card by the new one, the PSU should be up to the task. Correct?
- How do I know, if the 6-pin cable is capable of handling 150W instead of 75W? Is there a way to see the AWG rating?
- Assuming I would want to add the new card without unplugging the old one and I still have one free 6-pin cable… How do I know, if the PSU can handle the additional 75W necessary?
- I read that the card (MSI GeForce GTX 1070 Aero ITX) has a TDP of around 150W… So, is there a problem at all?
Here’s a picture of the info on the PSU:
Can anbody help me understand all that data with respect to my graphics card?

There is no problem — I have in the past done exactly that with a GTX 1070.
The 6-pin is able to deliver all the required power.
All you need is a 8-to-6 power adapter (or was it 6-to-8?).

GTX 1070 and 1070ti — Making MSI 1070 Gaming X run on 8-pin only?

When I connect my card, it asks me to connect all the power. Is it possible to make the card work without an additional 6 pin connection, only on 8 pin?

All Radeon cards work for me on 8 pins, I didn’t even try.

Apparently it takes a long time to reach you, but if the card has 8 + 6 pin power (it will be a shock right now) — it needs 8 + 6 pins to work.

Look, I’ll try to explain it to you in a simple way.
For example, I have an RX580 card, it has an 8 pin + 6 pin power connection. But in order to just run the card (without overclocking), just 8 pins will be enough, without 8 + 6 pins. Did I make my point clear or not?

but what prevents you from buying an adapter from 1 8 pin to 2 = 6 + 2 pin and 6 + 2 pin and connect it?

rx580 has less consumption than 1070, because they all go just 8 pins, this is how the sapphire stood out .
..
1070 for just 8 pins, especially for mining — you won’t plant it.

I have 1070 MSI gaming, today or tomorrow I will try to connect to one 8 pin, the point is that the card has 2 connectors for 6 and 6 + 2 pins, the problem is in the power supply, the server one is on the way. It turns out that to connect 1 card you need 6 pins per raiser, 6 and 8 pins per card, 18 connectors per farm.

Why are you mocking the cards??? The manufacturer is not a moron if he made a power supply of 6 + 8 pins.
Do not compare two completely different architectures in terms of consumption…

you will not run only on 8 pins, except for soldering or closing contacts, but you are unlikely to go for it.

Planted using an adapter from the raiser to 6 pin sat, 6 + 2 from the PSU flight norms, molex raiser 5 volts. I’ll unsolder the server one, but for now let them work, especially in the convict they have 180W consumption, one 6 pin is enough.

if you don’t understand or don’t want to figure it out, just look at the topic and wait for answers from experienced users
I personally don’t know the answer, because I haven’t tried
but I would like to know. since I have 3 bp with 2 8 pins and on the way 6 580 cards with 6 + 8 pins
so this is what is written in the technical manual for the 580s:
RX 580 ref = 185W.
RX 580 factory OC = 225+
PCI-I = 75W
8pin = 150W
6pin = 75W
as I understand it:
at load you need 185 watts, which naturally 1 8pin will not give out
and, accordingly, if you run 580 at reduced consumption, then 8 should be enough!
WHO TRIED?
Yes, and it seems to me that any vidyuha should start on 1 8 pins without load. and if this is not so, then it is strange

by the way my 1070 mines on 6 pins instead of 8 and everything is ok
