My PSU can read power like a wall outlet monitor.

It's Corsair's Link software. Need to have a corsair PSU that supports it. It's nice to have. I'm finding that with two 1080ti's under water and an OC'd 6900k that I'm almost hitting the limit of my AX1200i PSU. It will sometimes spike to 1000 watts. Wasn't expecting that.

Is there anyone who has had problems with melt PCIe power connectors / pins. I have read it before, about three standards on contacts, how much current they can handle. Likewise with the cables. The most marked for 80 degrees Celsius, but the sleeved cables are insulated by the stocking and getting warmer ... I myself made a hardware mod on my 1080Ti and evaluating. I put togather Asus Strix mITX and i7-7700K recently as more a test bench. It is calm at 4.9 GHz, but I'm waiting for a "Delid-Die-Mate 2". The GPU i can I run 2100 MHz in benchmarks but 10 hours of continuous heavy gameplay is another thing. I have not been so active lately because I have not been well. My previous setup was Asrock x79 extreme 9, 2xGTX 690, i7-3970x, 64Gb ram, 2xAX1200 and later Rampage 4 Extreme, 4-way SLI Titan v1. It has gone on 5.2 GHz and GPU modded Titan bios + 1.2 Ghz for 4-5 years. I gave it to an old colleague recently. Many problems i recognize but it is much easier to get one GPU and two ram modules to sing than four GPUs and eight ram modules.

The connectors can handle up to 80c, that doesnt mean they run at 80c. The cables should be rated higher, as 80 is quite low. Most I see are 90c minimum, with many of the more insulated types sporting 125c ratings as pretty standard.

The cables and connector are not going to be anywhere even remotely close to these temperatures, not even a little bit. And just cause the cables are insulated does not make them hotter, electric cablees dont really work like that. This isnt a CPU heatsink we are talking about. You have to exceed thee maximum amperage ratings by a pretty good margin for the conductors to heat up to anything you can even feel as being "warm". Im talking like at least 20% past max capacity. It would take a good 50% past max amp capacity of the conductors to get hot enough to feel hot.

I just came to think of the GTX 590. There are many who melted contacts and graphics cards, but there was something wrong with the overcurrent protection. There was some update later. I had two myself.

For those of us with vertical setups, would using graphite from a mechanical pencil work for this purpose? I'm not sure if electrical tape would be hold it in place but just a thought?

I am not an expert in this topic, but as far as I read in different sources, all other methods beside liquid metal or soldering a thin wire do not work, because they are not conductant enough and/or do not make enough contact with the ends of the shunt. This counts for silver paint and i am pretty sure for your suggestion too.

What he said.

The point is electrical conductivity to raise/lower the resistance (ohms) of the shunt itself. The shunt mod itself has a rated resistance you are just altering said resistance (in this case raising it since its a "shunt" resistor).

All that I can say is that the TXp are a beast. smokes my card. oh, and, shunt mod is a must for Pascal if under water. helps a lot.

Hey Guys, took me a while to finish my build but today i could finally press the power button for the first time. Fortunatly everything worked instantly.

First shot, no optimisation at all:

Settings:
Benchmark: Metro Last Light Redux, 4K, 4x Antialising, 1 Run
CPU Voltage: +0%
Power Limit: +0%
CPU Clock: +200MHz
Memory Clock: +500MHz

Results after 1 run(stable)
CPU Clock: 2100MHz (not one single drop)
Memory Clock: 6003MHz
Max Temp: 36°C
Max Power Target: 96% (no Power Limit at any time)

Higher clocks seem to need a higher voltage.

I am extremly satisfied being able to run steady 2100/6000 even at stock voltage. Shunt mod works perfectly!
