Well that took me by surprise. - Page 2

post #11 of 33
Thread Starter 
Well just got back home from my parents house. Might play around a little more tonight, might not. Going to make a Video and I will show my setup. Dont know how good the video will be so I will tell you what you will be looking at.


The main system is sitting on my Desk on a Tech Bench, I think it was the Sunbeam one. Yes I have 3 OCZ 700w PSUs hooked to the Rig. The reason I done this is I got the PSUs for $30 new so I only have $90.00 then $10.00 shipping in them so not bad for 2100w of power. And that allows me to put 1 480 on each PSU.

I also have 2 water loops, but there in a custom water box that I built and its under the desk. It houses the Rads,Fans,Fan controllers, and Pumps. So all you see is tubes that come up from a hole in the desk. Not the best setup but it works for me.

No for me to be able to see the total watts pulled I have to have all 3 PSUs plugged into the Kill A Watt unit and its plugs into 1 wall socket. I tell you no joke when I hit start on the Kombustor the lights dim in my room and then start to pulse. I wonder how much the 1 wall socket can take?

It depends on the breaker/conductor size of the circuit. If you are lucky its a 20A circuit with #12awg cable. It however might be a 15A circuit with #14awg cable. Also, you don't want to go over 80% capacity of a circuit, so that's 16A on a 20A circuit. You are definitely pushing the limits and eventually will start tripping the breaker. I would recommend running an extension cord to another circuit and split that up.

Power (measured in Watts as you know) is equal to current (amps or I) times voltage (volts or E)

P=I*E
2100=I*120
I=17.5A

go look at the breaker size for the circuit you are on.

should be 15A at 120v as per wiring standards in the usa or 1800w. the breakers or fuses are supposed to trip at 15A but i've measured up to about 25A on some circuits. circuit also doesn't mean one socket. a circuit can and most likely will consist of many sockets or fixtures (hence the dimming)

it's generally not advisable to go over the rating because they're in place for safety.

ps: your rig is mouthwatering

You don't want a fire starting in your wall.

In some places you will see 20A breakers and #12 wire, just depends on where you are but it really might be 15A.

Exactly, usually it's by room, so all the receptacles and lights in a given room would be on the same circuit and is why you see the lights dim.

I highly recommend running an extension cord to another circuit, make sure it's from a different breaker.

Sweet, Looking forward to your setup video man. I bet your desk is a mess with 3 psu's and watercooling
post #18 of 33
Might want to switch to a 220v circuit if you have one, and you want to run your psu's on the same circuit. If not, you may want to split the power between two circuits.

im guessing that you may be on a 20A circuit, your breaker should have tripped if it was 15A, even still if you are on a 20A circuit, your above the 80% capacity of the breaker.

Your running into a safety concern here. be careful.

Now you just need to buy an EVGa SR-2 and 2x6c Xeon's...but seriously I would hate to have your electric bill.

Ok, a few things.

1.) You should never load a socket like that, it is not cool, rad, awesome, or mouthwatering, it is just crazy. You are begging for a fire.

2.) If the lights in your house are flickering, you have a serous electrical problem. When your lights flicker, it means that resistance is above flow. Which means something is getting warm.

3.) Why do you think you need that much power. 2,100 watts is way to much for any pc. On your machine you should not need more then 1000watts.

Please check your smoke alarms.
