NEW PSU Died After 24 Hours?

[coinzoid]

Hello everyone, recently I've ordered following system:

EVGA 1200 P2 PSU
6 x rx480 Nitro+s
Risers v6
8 GB DDR3 RAM
SSD
z87 deluxe quad
g1840 cpu

STORY: I've mounted my system and gpus on a rack and system worked fine except 6th gpu. It looked like thunderbolt on mobo enables itself on connecting 6th riser. This mobo has 7 pcie slots and i have configured slots as gen2.

Anyway, while researching for thunderbolt issue, I faced another problem. For no reason my psu produced a big noise (bang) and turned off itself and also turned off circuit breaker. As soon as connecting PSU with PSU tester it is tripping circuit breaker again with same noise.

My circuit breaker is B class Siemens 25 Amper.

Later, I tried to unplug everything and only use PSU tester on another outlet. Same thing happened. My friend checked it and told me i should return PSU. I've asked him if I should upgrade circuit breaker with another large capacity one but he said that would be overkill. Before dying, psu and system is working fine and issue happened randomly just after 2 minutes of decreasing temperature of Natural gas combi. Basically, when using room termostat, if you set temp to a lower value, it turns off the combi remotely. Somehow, I think it is not just random crash and looking for ways to adjust my environment.

What else is on that circuit? One rig shouldnt pull more that about 12 or 13 amps @ 120v with 6 gpus. I installed double pole breakers and wired my outlets to 240v so that amp pull drops in half and i can now run 2 rigs on a 20 amp circuit. I am not sure why you have a 25amp breaker though. Most newer houses are wired with 12 gauge wire and are on 20 amp breakers. Alot of the older homes have 14 gauge wire and should be on 15 amp breaker. See what size wire is feeding you outlet and to your breaker. Double check its not overloaded. If you starve the power supply it will likely blow. Been there and done that.

Either you have some really dirty power that killed the PSU or you just got a bad PSU is my guess.

If you just purchased the PSU, return it and swap it out, otherwise I would buy another and send that one off to EVGA for repairs.

Bang in a psu = boiled cap and explode  = dead = rma  get it replaced.


It should not have happened.


so the psu was defective or a short in the other gear killed it.

[velbet]

are you doing dual mining ?

[arielbit]

or worse, it took some of your gear with it to the netherworld.

@navydude I live in Europe (Turkey) so we have 240 instead of 120. The apartment i live in is 25 years old. So wiring in my house is not quite new. Only good wiring is the one I've planned and deployed for instant water heater at my bathroom. Later, we switched to natural gas combi and that wiring does not have anything attached. Also circuit breaker connected to that wire is Siemens B40.

Today, I've upgraded the problematic circuit breaker from Siemens B25 to Siemens B32 and found out EVGA still tripping circuit breaker.

I'm pretty sure, air conditioner (inverter model) in my room and maybe combi is connected to same circuit breaker. However, when testing EVGA with other outlets, it tripped main circuit breaker of my apartment.

A question is: I have two peripheral cable from my psu and i was connecting two gpus usb/molex riser per cable before issue happening. Is this a mistake?

If you want i can provide screenshots of my setup.

@velbet No I didn't dual mine yet. I was considering it but didn't have time to test.

That depends.  You can check the wires to see how hot they are getting as you run.  If they are getting really hot then you are pulling too much power and need to separate them.  It is a little subjective, I mean what does "really hot" mean?  But consider that you really don't want to be responsible for burning the place down and maybe killing some neighbors so use good judgment.  It isn't unusual for the wires to be warm but if you think they seem more than warm then separate them.

I am surprised by this though, my experience with EVGA is that the high end PSU's are rock solid.  But as you describe it, it sounds like without a doubt the PSU has failed and needs to be replaced, just as others have said.

I recommend for rig power distribution monitoring to get a good termal camera, it can help you easily pinpoint where your "hotspot" are, and take mesure to fix it. A must have for serious miners !

You shouldnt just be upping the size of your mcbs without checking how its wired, You may have a ring main wired in 2.5mm in which case the 32 is acceptable  but im not sure how its done in turkey, chances are youve put in too large a circuit breaker for for the circuit. you may have luck changing out the mcb for a c type breaker which will give you a larger starting current which may me the issue as you try starting up. You also dont mention if you have an rcd on this circuit because if you do then it would be safe to assume its 30ma and if your loading it up with a lot of computer equipment you will soon have more leakage current than  that rcd can cope with.

On another note that psu shouldnt draw more than 5 amps flat out so i doubt your circuit is overloaded unless your running a lot of other things on it.

Try to run the system with one gpu if ok, then add another in sequance until the problem appears , maybe a raiser problem if it's powered raisers maybe one of them is shorting the psu so it shorts the breaker, the main reason for circuit breaker to close is a short circuit not an overload , you must be searching for short circuit.

[philipma1957]

Hey guys he said his psu made a loud popping noise.

95% chance = popped cap = dead psu = rma


At op.

that psu comes with this part


https://www.newegg.com/Product/Product.aspx?Item=9SIA2F84BC9923&cm_re=evga_1200_p2-_-17-438-029-_-Product

1)first turn switch on psu to off

2) so plug power cable into wall
3) plug psu power cable into psu power switch on psu is off
4) 24 pin mobo cable only no other cable into psu
5) tester on the open end of mobo cable

then using the switch on the psu turn it to on

my guess is the circuit breaker in your home trips due to a psu short

You have a 1200 watt psu. Look at the side. That is not 1200 watt of 12volt. That is most likely 1000 at 12volt and 200 at 5 and 3 volt. So good job you killed your psu. The psu was not faulty as it was working until you overloaded the 12 volt rail. You should not rma as the problem was with your lack of knowledge and not the PSU.

1200W power supply should be able to support 6X RX 480.

[stoniestfool]

No it should not. 6 rx480's will pull over 1000 watts. You are not realizing a 1200 watt psu will only output a max of 1000 watts of 12volt power. GPU'S only use 12 volt. No 5 or 3 volt rails ever connect to gpu's. Sorry but you are not correct as you have no math to back up your statement. Only incorrect assumption. If you had 6 undervolted 480's it might pull around 1000. That is if you are running stock firmware and no overclocking That is also assuming you are ming eth only. No zcach , no dual mining no xmr..However, even then each gpu will spike and eventually you will go over 1000 and blow your psu.
     I am sure you ignorantly responded " 1200W power supply should be able to support 6X RX 480" without even looking at the side of the psu which would have clearly stated what I am tellinmg you.

i am not sure what is above based on; instructions clearly say 1198.8W on 12v rail:
http://www.evga.com/Products/Product.aspx?pn=220-P2-1200-X1

he messed up something else OR his wiring is old OR EVGA is defective (least likely in the beginning, but likely now).

[vapourminer]

that psu has overcurrent protection, it should just shut down if overloaded. not blow and make a "bang" noise, which indicated physical damage to the psu.

the psu is toast.

RMA it.

[RentGPU]

A poped circuit breaker means a short circuit not an overload ......thats it , if you power up the psu only and it did the same problem then you have a shorted psu

[stoniestfool]

I reviewed the specs and was wrong. This psu will output 1200 watts on the 12volt rail. However. Most psu's are not rated of the 12v , I see this one is.
If the psu keeps shutting off from overcurrent then he is pulling to much current. THAT IS THE DEFINITION OF OVERCURRENT.

I have 2 rigs each with 1 ref 480 and 5 rx 470. They each pull over 1200 watts while dual mining. Have not tried zcash miner since verion 9. On version 9 they would run for short periods until the spikes overloaded the 12volt. So I know 6 480's will pull even more.
  You assuming psu's could be defective. The odds are so slim you would have a better chance at hitting the lotto.  I am a hardware expert. It is not like a cap can be incorrectly made.  The only thing that would make a psu defective would be a bad solder joint.
 

If he had modded roms and was only mining eth that yes the psu could be the problem. Overclocked ref 480's dual mining pull 225 watts. so do the math. 6 x 225 is higher than 1200. Even non ref 480's pull 200. So if 1 gpu spiked it would go over the 1200 watts. The fact that the psu is working but keeps shutting off due to overcurrent protection eliminates the possibility of the psu being fault. IMHO. Yes . I know when you google tdp rx 480 it says 140 to 160 watt. That is on stock. On stock settings it would take 3 years for roi if your electric is like mine at 13 cents per kilowatt.

Now that the psu is blowing the circuit breaker the psu is probably bad. That is not what started his problems, though.

That was based off my 860 plantinum evga. The model I have is only rated a 752 on the 12v. Also, the stuggles I went through when I could not dual mine even 5 gpu's without the overcurrent protection shutting off the psu. 1 ref 480 I though would be 160 and 4 470 I though were 120. Total should have been 680. The walmeter would say around 850. I had not counted for the overvoltage nor the fact it was really 752 on 12v and not 860.

I do see I made an incorrect assumption that his psu was simuliar. However, the majority of psu's are like mine. The 12 volt rail is almost always lower than the psu rating.
