What is your opinion on 3x 8pin graphics cards

I don't think there's anything wrong with them using more connectors. Whether the power draw is acceptable.... depends on how hot you'd like your room to be. ;)

Ehh..... I think its nice for heavy overclockers, who may use more than 2 can provide, but for normal use, it doesnt really matter.

 

Though it does look pretty nice when you have rgb 8pin pcie powers

2 cables vs 3, what's the matter? as long as it works... my case is a regular one so I don't even get to see those cables.

I buy graphics cards based on 3 8 pins. I hate being power limited

This is the way they should be... But if dGPUs must use a power connector, limit them to one and only one.

So less power hungry cards have to share the same big connector as the flagship cards? Or PSUs come with more different connectors to suit different power level of cards, as a result a lot of unused cables per PSU?

If dGPUs were limited to only one Connector, then their wouldn't be any need for PSUs to extras now would there? Do you want a Computer or a Space Heater?

If you don't want a powerful computer don't buy components that use a lot of power and produce heat. Some of use need or want more power and don't mind the heat. If a GT1030 is enough for you, leave us alone. Nvidia is trying to push a single connector but the connector is very large and unsuitable for lower power cards as it's sorta tall and awkard, again, buy GPUs with a single 6 pin or 8 pin if you don't need or want a lot of power.

The amount of Wattage consumed and waste Heat outputted has little to do with performance.

What.... it scales almost linearly within arches for the same voltage and temperature. An RTX 2060 will use less power than an RTX 2080 but gets less performance. At the very top end yes it no longer scales, more performance usually equals a lot of extra power but that's only at the very high end if you push the hardware too far. Compared to 2010, the new generations of GPUs are getting better and better each time at not ballooning power limits, however I'm an extreme overclocker so pushing a single GPU to 500 watts is normal for me.

150 watt power limit, in actuality it can draw a lot more than that, but the specification for the 8 pin connector is 150 watts.

It is getting ridiculous.

 

I used to run my GPUs for F@H but the power draw has come to a point where I can not justify it anymore. Germany has the highest electricity costs in the world with ~0,28 Euro per Kw/h.

That is why they have standards for cables. We won't be using a 24 pin power connector for our SATA drives anytime soon. 

 

Personally, I tolerate the cables as it doesn't make a difference if its one or two cables, at least have enough power and room for the power draw in three PCIe cables instead of overloading and melting two or less. As they say, you gotta have the right tool for the job.

If the hardware is made with the same technology (which is always the case if they are from the same period of time and company), it does.

Only 3 12V and 5 ground 18AWG (in most cases) wires of up to 650mm length, not sure if some PSUs have longer cables for the PCIe 6+2 plug. 18AWG wires have resistance of 0.021ohm/metre, or 0.00728ohms for a single 6+2pin cable. Since V*I = P and V = I*R, in ideal cases at 150W@12V output from the PSU there will be 12.5A of current and the overall resistance of the wires and PCIe device will be 0.96ohms only. Wire and card are connected in series, which means about 0.76% that power or 1.14W is loss through the cable, pretty safe at this point. At 200W (that's what Nvidia's older flagship cards roughly pull when they are under the 250w power limit reference spec), that's 16.67A of current and overall resistance has to be only 0.72ohms. Heat output from cable is now over 1% (2W) at this point and the cable will feel warm if you touch it with your bare hands. At 300W (since each cable usually has two 6+2 pin plugs, this is the number each cable is rated to supply), now we need 25A and overall resistance of 0.48ohms. This means 1.516% (4.55W) of heat loss from the wires and the card is only receiving a voltage of 11.8V from its 12V to ground connections. That's a problem and apparently, enough to make cards like the 2080Ti crash.
