Watts to high? Help not burn my house down.

[flip4flop]

Almost lit the dang house on fire.


Fired up the first rig and drew way more power than I thought almost resulting in a disaster.

4 MSI GTX 1070s
i5-6500
Asus B250
120gb SSD
1000w EVGA power supply


Ran benchmarks on NiceHash with no issue

Started mining and pulling 1059 watts.  Cable started melting (was my old power supply cable not the 1000 one) 

Turned off and replaced with a server cable rated up to 1800 watts

I didnt expect to pull over 1000 watts with my setup and I hope it was a stupid mistake with the wrong PSU cable.

Any thoughts on why I am pulling so much power?  Only expect 600 total for the cards at the max and then maybe 150 for the remainder of the stuff.

are you using nicehash miner? try EWBF

also try other tweak in after burner.

this is a good read

You need to download and run a utility such as MSI's Afterburner to reduce your power usage.  https://www.msi.com/page/afterburner

Once installed, run it and adjust your Power Limit settings to around 75 to 80%. You may need to adjust the clocks a little too, if you are mining Ethereum you can increase the memory and decrease the core clock.

There are a ton of threads already on this subject as well as a lot of YouTube videos so I won't go into all of the details, but this should be enough to get you started.

Very odd because I have two EVGA 1070 (Watercooled version) and 3 Zotax 1070 mini on a single EVGA 1000w PSU.  At 80% it draws under 700 watts.  I been using this settings for few months straight.

I used nicehash to test the rig. Will be using EWBF when I tweak everything.  More concerned with how I pulled 1057 watts and why?  I’m assuming it was because of the alternate power cord that was to small. After we shut down and pulled the semi melted cord out and replaced it with a 14 gauge server cable it dropped to around 840 watts for 10 mins on nicehash

Was using the wrong size cable the culprit? I thought they were interchangeable. Going to run 3 cards instead of 4 till I know what the cause of the large power draw to the wall was.

resistance of the say 18ga ac wire causes it.

The 14ga has less  resistance saves 200 watts.

Next load proper software to set tdp to 70 or 75%.

Running nvidia at 100% is just dumb. Also some 1070s are
 200 watts
 175 watts
 150 watts at 100%

Do any of your gpus have 2 sockets vs 1 ?  They will have higher stock tdp.

That’s why you need msi afterburner

the thinner the wire, the more power it consumed, or other called it more power loss.

Most likely he used a PSU cable designed to power a monitor.

They look the same and the plug fits. I've done the same mistake. You can tell right away because the cable gets hot very fast.

Thanks for the info.  I would probably have made the same mistake and melted the cable...
