NEW PSU Died After 24 Hours?

[Biodom]

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

yes, of course, PSU is probably dead now and it was most likely not what started his problems, you are right.
Phil told him how to test PSU without connecting it to anything (with a plastic dummy/jumper short for the 24 pin connector, which is usually included in the box these days).

@ op I don't want to curse at you and call you terrible names.

But I have four firefighter relatives alive and one dead ( World Trade Center)

Your choice of putting in a bigger breaker was bad. Unsafe and if you had a fire with loss of life criminal neglect.

Never put in a bigger breaker. Unless you know exactly what you are doing.

Please be more careful.

Dude even if you know what your doing you should never upgrade the circuit breaker. The reason circuit breaker have rating is to match the rating of the wire in the wall. So unless you change the wire there is never a reason to upgrade the breaker.

[alucard20724]

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

actually, both conditions will cause it to pop.

if he only had the power supply hooked up to the circuit breaker, then it's highly unlikely he overloaded it, but instead shorted it because a properly function 1200w power supply will not pull enough current to overload a 25 amp circuit circuit breaker.

[QuintLeo]

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

 NEVER EVER DO THAT.

 You have just created a MAJOR fire hazard.

 It is safe to replace a breaker with one at a LOWER amperage rating, but NEVER EVER put a higher-rated breaker on a circuit.



 As far as the power supply goes - it was probably defective, the most common time for anything electronic to die is very early in it's lifetime (this is commonly known as "infant mortality"), even folks that make good gear will have occasional failures early on.

 Probably since it's so new you can get it replaced through the dealer you bought it from.



 Most if not all power supplies in the 1KW+ rated range are capable of supplying their full rated output or very close to it on just the +12V rail(s).
 It doesn't hurt to CHECK ahead of time though, there are a FEW exceptions out there (or used to be).

If you know exactly what you are doing when you upgrade a circuit breaker from 15 to 20 or 25 to 32 amps it means you know to upgrade the wire.

But in the case of the op. Whom has no fucking idea of what he is doing he needs to be more careful.

My early post told him to rma the psu.

He did not he upgraded the circuit breaker.  And of course popped the breaker.

I offer my prayers for the op and his family and the fireman that serve his town.

[NewbieMiner.IO]

It is PSU faults , it is defective , File a consumer complaint and ask for a refund .

[coinzoid]

I haven't mentioned but I was using modded bios from Jukebox (Powersave bios) and was pulling around 820 watts from wall. If i downvolt i was able to pull around 700 watts.

Seller is kind enough to offer a replacement. But I'm afraid a replacement will cause same issue. So I need to take measures to prevent same problem if it is a mistake on my end. I'm also willing to re-pay the item cost, if it turns out to be my mistake.

[coinzoid]

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



see this

I have tested my psu with psu tester and result is same. I'm scared to touch Power On switch to make the test so it is already on Power ON position before connecting cable to wall. As soon as connecting PSU to wall socket problem repeats itself.

The same problem being the breaker in your fuse boxes blows?  Did you buy this psu in a rig or separately? If you bought this in a rig perhaps the seller used refurbished psu's to save cost.  The psu is definitely bad if when you tested it by itself it blows the fuse. At that point if working correctly the psu is pulling almost no power. I see you were using power save bios so my assumption you must be pulling more than 1200 watts was wrong.
The rig was mining before you tried the 6th card?
When you are testing with the psu tester are all the other cables disconnected? Of course the 24 pin must be connected or maybe not if the tester plugs directly into the psu.

 If you still have the gpu cables connected to the psu but not the gpu's. I am wondering if you pulled to much power on 1 of the gpu connectors. This would cause the wires to get hot enough to melt the coating. Then underneath the sheath the individual wires would be touching. That would be a short and cause this problem.

[philipma1957]

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.

so like I said here in the beginning   the psu is bad.

as to what else is wrong you can not tell until you get a new psu.

once you get a new psu   do not attach to the mobo.

just test it with the little black tester  the mobo cable and the power cable.


once it works (95% chance it will work)   do not do any thing  come back here and tell us it passed.

I will give you  a step by step test method   with photos.

This thread now has me thinking. A nearby store has a few Corsair AX1200i on sale (well they are actually refurbished) for around $150 each. I was going to take a chance and pick a couple up, but my first concern was they only carry a 90 day warranty. Now I am also concerned if they might be a fire hazard, as what was the reason they were refurbished.  Anyone have luck with refurbished PSU units? The store does have a 30 day policy, so if anything is immediately wrong I am ok, but I am think of once past the 90 day mark.

[stoniestfool]

There is no greater chance of a refurbished psu to caught fire than a new psu. You will get slightly less efficiency the same as if it were used. That is because caps wear overtime. How motherboard manufacturers advertise how many hours of use their caps are rated for.The fire hazard would be from improper installation. As far as longevity goes a refurbished psu would be fine for a pc that is not running constantly. For a mining rig that will run constantly that is just a bad idea.Probably why this psu died after 24 hours.

@philipma1957
I'll come back and tell you once test is passed with new product. FYI, I've tested current PSU before connecting components to it and it has acted very well with built-in tester. But it died later, as I stated.

Shall I downgrade the circuit breaker back to Siemens B25? Remember I've upgraded it to Siemens B32 without upgrading cables. Due to building is 25 years old, it is difficult to change cables. Maybe I should create a new electrical line through wall but not sure what would be the best way to do it. I belive it will be impossible to use existing tunnels as they are very tight.

The same problem being the breaker in your fuse boxes blows?

It is tripping breaker, nothing like blow. Once I turn on breaker, breaker is working again. But PSU is tripping it even with only PSU tester is attached.

Did you buy this psu in a rig or separately?

I've bought PSU from an online store. Other components from different store. The box was unopened and I can tell, product was unused. Unless it was refurbished.

@stoniestfool

If you bought this in a rig perhaps the seller used refurbished psu's to save cost.  The psu is definitely bad if when you tested it by itself it blows the fuse. At that point if working correctly the psu is pulling almost no power. I see you were using power save bios so my assumption you must be pulling more than 1200 watts was wrong.

Correct, I also have kill a watt and I'm pretty sure 5 cards was pulling around 800 watts. Even with 6th gpu I should be pulling around 950 watts. I'm using another computer to mod bios of gpus before connecting them to new rig.

The rig was mining before you tried the 6th card?

Yes, it was hashing ETH using Claymore and my hashrate per gpu was 29.3 using modded bioses.

When you are testing with the psu tester are all the other cables disconnected? Of course the 24 pin must be connected or maybe not if the tester plugs directly into the psu.

PSU tester is attached to mobo cable. So nothing else was connected while testing PSU after issue.

If you still have the gpu cables connected to the psu but not the gpu's. I am wondering if you pulled to much power on 1 of the gpu connectors. This would cause the wires to get hot enough to melt the coating. Then underneath the sheath the individual wires would be touching. That would be a short and cause this problem.

Most likely due to a short this issue is happening. But I'm not an expert so I'll be following suggestions posted here.

[philipma1957]

Put the old breaker back in the breaker box.

Once you have the replacement let us know.

At this point. I suspect the psu was defective and popped a cap.

It happens.

[arielbit]

advice: add another layer of protection!

I'm using surge protector extension wire (2500W rating) that has a push to reset breaker built-in --> serves as first protection before the breaker trips

20A breaker --->to 2x outlet at 16A (socket rating each)
       - 2500w surge protect extension wire per outlet


some maths: (the secret is in the Amps)

20A breaker / AWG #12:
 plug 1: 2500W/220v  = 11.36A (~max)  --> outlet is 16A rating (safe) , wire is 20A breaker (safe)

 plug 2: 2500W/220v  = 11.36A (~max)  --> outlet is 16A rating (safe) , wire is 20A breaker (safe)

notes:
  - if 2500W is reached in both of the 2x surge protector extension wires (11.36A x 2 = 22.72A) the 20A breaker trips (solution: reduce load)
  - if one of the 2500W protector extension wire trips (11.36A reached or exceeded) (solution: reduce load)

the the load in my 2500W surge protector extension wires are tested thru time when voltage fluctuates, if voltage goes down (power company's service transformer get loaded) Ampere goes up a bit(ohms law)..today a one of my 2500W surge protector extension wire tripped(been running for about two weeks already), I unplugged my rig with 1x r9 390 and plugged it in my newly bought 2500W surge protector extension wire (will add a rig or two there for expansion).

i have just sent 12 x 1300 Gold psu back to evga out of about 200.  As soon as i turned it on it sounded like a shotgun went off.  They were almost all sequential as well.  I thought I was doing something wrong, turns out it was a bad (weak) internal fuse.  They took them back asap no questions

Hello, I've received new psu (EVGA 1200 P2 again) and tested it using built-in psu tester for a few minutes. Fans spin and it looks like it is working.

Today, I'm going to put back old breaker back in breaker box as suggested and listen your suggestions.

I've Belkin F9M823YY2M-GRY as 8 socket surge protector. I can use this if helpful. Besides, I have used very cheap US to EU plug converter with dead psu. Shall I stick to it or order a better one? My PSU has US plug. But my location is EU so i need a converter.

I've figured out that that 25Amper breaker was connected to almost all wall sockets, air conditioner (not used at winter), gas combi and my pc.

Remember I've said I've a very good cable that is connected to 40Amper breaker, it was used for instant water heater at my bathroom but later it became available for other possible uses. At this time, we are not using it but I may need to extend that cable if you suggest to do so.

I'll apply your recommendations before turning my miner on again

okay  lets see a link  for the adapter as the adapter  may be the cause of the short.

under small test load  which passed you are fine.  check 1

check 2 is a look see at the adapter.

check 3 is not to be done until check 2

It sucks  but   I have had cheap adapters kill psus and gear.

Once we figure out the adapter is good or get a better one

check 3 is  plug the  24 pin into the mobo  plug the cpu cable into the mobo  using no cards  boot and see if the mobo posts.  this means you need to plug a video cable into the mobo's video

check 4  if check 3 passes    put in 1 video card  fire it up  don't mine with it.

check 5 if check 4 passes   test that same video card in all six slots don't mine with it

check 6 if check 5 passes  test the same video card in all six slots  via mining with it  1 hour each slot

check 7 if check 6 passes add a video card  mine with 2 video cards for an hour.

check 8 if check 7 passes add a video card mine with 3 video cards for an hour.

check 9 if check 8 passes add a video card mine with 4 video cards   for at least 2 hours

check 10 if check 9 passes add a video card mine with 5 video cards for at least 6 hours.


at this point  if you have 5 working video cards  you may as well stay at 5.  going to six  may not be worth it

I've used this product and noted following:

Bottom of adapter says 13A 250V
PSU cable has 15A 125V

Shall i buy a better adapter? I was hesitant to use this one but seller said there would be no problems. If required would you recommend following?
