Kill-A-Watt beeping for 9 GPU Rig

[tipac]

Hi i need help urgently
I recently built my first rig, it include 7 RX580 8GB, 1 GTX 1080 , 1 GTX 1070 ti, motherboard asus b250
All gpu runs at temp 65-70, my kill-a-watt is beeping continously

It shows about 1800 Watts and 5.40 kWh
Is that normal ?
Any advice would help a lot!
Thanks

if running at 120V that is 15 Amps... check your killawatt see what its limitation is.

i have 2 psu, first is evga supernova 1300 and second is corsair 850. i connected both in same wall.

[dagarair]

you did not understand what i said so i will stop now.

[tipac]

if i understand correctly 15 amp is 1800 watts so kill-a-watt is beeping because it goes over that range ?
How do i check killawatt limitation ?
Thanks

Looking at the sticker on the back MIGHT provide a clue

Yes this is correct, 1800 watts is too much for a killawatt to safely measure for extended periods of time. It will overheat and possibly cause a fire, that's why it's alerting you to a problem with the beeps. On the back of the device it should show a "max amps" rating, going over that value is unsafe.

[tipac]

Thank you so much for reponses! On the back of killawatt it says: max voltage: 120vac, max.power:1800w
In this case what should i do ? Connect 1 psu in one outlet and the second psu in different outlet ?

Might also want to educate yourself on the max amp draw of the circuit you're running off of before you start tripping breakers.  If you're running off of a 15A circuit, you should only be using 80% max.

I definitely should, thanks for advice!
So if i connect the evga 1300w in one outlet in basement where nothing else is connected like tv or refrigerator and the second power supply i connect it in different outlet/breaker via and extension, will that be safe ?
Thanks

You could have ten outlets all on the same 15A breaker.  The number of outlets does not matter.  You really need to take a look at your breaker box and hope they are labeled.  If not ... You can just shut one off and go start testing outlets.  The ones that don't work are all on that one circuit that you shut off. 

Usually all of the outlets in one room are going to be on the same circuit.  You'll have exceptions for washer/dryer, range, ect.

You're running over 1800 watts from one outlet, which means your are pulling over 1800 watts from one circuit.

If that's a 120V 15A circuit you are in dangerous territory. You should not run a continuous load greater than 80% of your total available wattage on any given circuit. I'm guessing you are using other electronics on this same circuit and are overloading your circuit. It's going to eventually start tripping. If you have an older house/apartment you have a fire risk of the breaker not tripping at a given heat.

Before you build your first rig, buy your first part, or think about pressing the power button you need to know your power limitations. This is why there are threads and pictures of people with burned out rigs, cables, and components.

You need to shut your rig off until you map your circuits to disperse your load correctly.

yeah you are fucking operating un safely.


at least you asked us.

and why are you pulling 1800+ watts with 9 cards?

you don't have proper settings for the cards that is why.

do you use msi afterburner?

[tipac]

I test reseted each outlet and found that in my basement 2 outlet use different breakers, does that means that i can use around 1000 watts for each breaker ? will it be safe ? I mean if i have 5 different breakers in a house, does it mean i can safely run up to 1000 watts without a problem ? i live in california, the house was just built in 2015 so i think it has installed the latest electricity standard
Also if the killawatt shows 1000 watts usage for each 4 gpu does that mean that at the end of month the electricity bill will be (1000 watts = 1 kw, 1 day = 24 kw, 1 kw = 0.17$ so is around 4$ per day to run 4 gpu ?) is that correct ? lets say if i undervolt them i might save 20% so for 10 gpu the bill will be around 330$ a month, is that normal or i'm doing something wrong ?
thanks

Are your breakers 15 Amp or 20 Amp breakers?

A 20 Amp breaker can handle 1920 watts at the 80% standard "safe" capacity, whereas a 15 Amp breaker can handle 1440 watts at the 80% standard "safe" capacity.

If you're pulling 1800+ watts then you must be running all your GPUs at stock 100% power limit. You will get better results if you lower the power limit using software such as MSI Afterburner.  Typically you can drop the power limit to 80% and still get the same hashrate with a modest overclock.... and have much lower power and less heat to deal with.

msi afterburner doesn't detect my amd radeon rx 580 cards (i think is driver issue) but the amd watt tool detect them,
what is the recommendation settings for these rx580 cards ? should i set power limit to -10% or more ? Also is it ok if i set the fans at 100% ? If someone can share the recommended settings for oficial watt tool it would help a lot!
And the last thing i urgently need to know, is it ok if i connect each evga 1300w psu in different outlet / different breaker via extension cable and use both them for same rig, will that be ok for the whole house ? when it says maximum 1800 watts limit, does that mean per whole house or per breaker ?
ps: i'm learning first time about these electricity things, thanks everyone for helpful tips. you saved me a lot of time researching
Thanks very much!!!

Set thepower to -10% onthe 7 amd.
Set thefansto 90%

Tell us what the meter drops to.

This!

You have one and possibly two very real fire hazards going on until you correct this. As has been pointed out the Kill-a-watt is only rated at 15 amps at 120V, and even then that is for a maximum snapshot reading and not meant for continuous 24/7 operation with that much current running through it.

The other potential hazard as Elder III poitned out is if you are running this through a 15 amp circuit. You can check the breaker panel to see if the outlet you are using is connected via a 15 or 20 amp breaker. In the US all circuit ratings are required to be derated to 80% of maximum capacity for continuous operation, which mining most definitely qualifies.

he simply needs to lower the power use it appears every card is maxed on power

if he lowered the power used to normal rates.

such as 70%  on the nvidia and to  -10 or -15 on the amd the power would drop a ton.

In the meantime he is certainly  running too hard to be safe.

In case anyone was wondering. The Kill-o-watt meters do work on 240v without issue. They calculate everything as expected.

15a is the limit, even at 240v. They didn't like being pushed when we setup a few 20a 240v circuits.
