12V-2x6 Adapter with Monitoring and Shunt Resistors Appears for NVIDIA's GPUs

Or, we can hire someone to keep looking from the side panel while we are using our PC and in case he sees smoke to alarm us to quickly shut down the PC.

but the magic will be gone… ! lol.

I'm not too surprised by this since the last major thread on this issue here. In fact I thought it would be an interesting idea if CableMod and Thermal Grizzly could reimplement their previous solutions by including the necessary circuitry to manage the power connector and protect the system. After all what's a $50 to $100 power adaptor but a drop in the bucket of cost when your paying $1,000+ for a GPU without proper safety measures? At this point there is a lot of money to be had among GPU owners who have to worry about this problem and would probably buy such a device to ensure their system doesn't go up in smoke, especially those that use custom cables.

12VHP is an ATX spec.

Well that fixes everything...

A community style solution for a premium product's deficiency.

Kind of like Linux vs Windows. Except that Linux actually works.

It's a good idea but it should automatically cut all power to the GPU if any overload is detected instead of just ringing an alarm

Would that not cause the card to attempt to draw 600W from slot, at least temporarily?

Well there's an idea, a 12V smoke detector, a built in sprinkler system, as well as automatic power cut off.
See Nvidia is creating jobs and opportunities for people.

Everyone needs to switch to 4-spring, not just the cables that come with the GPU's.

It needs to become a new standard.

I agree. In fact, seeing how quickly 2-spring plugs came about, I won't be surprised if 4-spring is not the standard 12vHPWR cable included with a Corsair PSU in 2027.

I just checked a few lines.

A Shunt resistor is not a fuse.
Monitoring is not a safety feature.

A fuse is a safety feature.

that stuff also needs temperature measurement probes.



Nope - Nope- Nope.

Really how do yo measure a current with a shunt - resistor? Maybe ohms law + shunt resistor + an analog / digital - converter in a microcontroller?

--

they should have added some circuitry on the psu side, not on the graphic card site, to hardware limit the current per wire. Which should be in the power supply unit in the first place. That connector is only specified for 600 Watts not 750 Watts what some overclockers use it for.

I have a Corsair HX1500i PSU. It has a USB-C port that feeds sensor data to the motherboard. I can use a Windows app to monitor the volts, amps and watts for each of the 3 PSU rails. It monitors temperature at 2 places. It does not monitor the individual plugs and definitely does not monitor the individual wires in each plug. I wonder how much it would cost to add that additional sensor data to a PSU.

I hope you do not misunderstand me.

You power supply unit does not have any accuracy on the "measurements" like a true rms multimeter has. Therefore it is not a valid measurement. It's the same as with those cheap 8-15€ Schuko - 230V - WIFI measurement plugs. No accuracy given.

I would only trust a true rms clamp - multimeter in this regard or an oscilloscope with current probes.

I did not expect to see even an accuracy in the first place.

"The Corsair HX1500i's USB-C data port provides accurate and reliable information about power consumption, efficiency, and temperature through Corsair's iCUE software. However, when comparing its accuracy to a true RMS (Root Mean Square) multimeter, there are some differences to consider.

A true RMS multimeter is designed to measure both sinusoidal and non-sinusoidal AC waveforms accurately. It calculates the effective value of an AC waveform, providing precise measurements even in the presence of waveform distortions2. True RMS multimeters are highly accurate and are widely used in various applications, including industrial and commercial settings.

While the Corsair HX1500i provides accurate data for monitoring your PSU's performance, a true RMS multimeter offers a higher level of accuracy for measuring AC waveforms, especially in complex and distorted environments. If you need precise measurements for electrical work, a true RMS multimeter is the better choice."
