powersuply causes fuzeblow! what is going on?

[1994dominik]

sorry for my english im from germany

i am at the procces of building my new pc but for some reason when i did the pretest of the parts when i connected the powersuply with the plug and then switch the button from off to on it caused the fuze to short out!

i have a corsair rm850x white

at that time i had my old computer on as well as one monitor for stresstestboot and one for a youtubevideo how to build a pc!

i tried it with the computer turned off and still i got a fuze short when i switched the powersupply to on!

i even unplugged my consoles that werent on as well as my tv(off), still the fuze shorted out!

when i tried again only the monitor and the powersupply was connected, same thing

what could be the problem? can the powersupply realy take that much voltage? i live in germany so my plugvoltage is 230V and the powersupply at max needs 12!

is the problem the plug itselfe?



AND VERY IMPORTANT QUESTION

i had my motherboard(32 ram,cpu9900k, 970evo) with my gpu connected to the powersupply coonnected when the fuze shorted out! could that have damaged the components? and could i test the powersupply in other plugs to test it or does fuze shorted cause it to damage the poowersupply?

There is a switch on the back of the PSU that is used to determine voltage, you need to move the switch to the proper voltage. The voltage should be stated on the switch. The switch is not the power switch, it is a flat switch which you throw with a flat head screwdriver.

I suspect your psu is defective.
So far as I can tell, there is no input voltage switch, it is automatic.
Double check to see that you do not have a short somewhere.
Take the motherboard out of the case and test that way.

Yes, there is a possibility that other parts could have been damaged, but I suspect you are ok.


Time to RMA the psu and try your parts with a known good psu.

i asked somewhere else and they said i triped my breaker:
The PSU can't be DOA because it tripped the breaker. You are are just pulling too many Amps on that breaker. Typical household breakers are 15 or 20 amp. If your's is a 15 that would explain why so little electronics would trip. Remember you have to calculate any lights and fans into your power/amp draw. PSU's are all QC to make sure they only output the correct voltage so there should never be any issue with damage to your MOBO. I had the same issue at my first apartment. Just get an extension cord such as 1625W 13 amp and plug it into a socket on a different breaker.

i looked its 16a

is it only cause i have 2pc on one breaker?

cause i could for the time being use extention to get power from a other breaker and when the transfer is complete just hook my new pc to the breaker in my room. when i pretested my system i once did it with the old pc on and one time with the pc off, but ididnt turn off the switch on my old pc so it still draw power that could be the reason right? besides my old pc is hookes to a very old powerstrip!

the new one has overvoltageprotection so frying my pc is not that likely right?

 

[geofelt]

Yes, running two pc's on the same circuit could trip a circuit breaker.
But, you indicated that you tried your new setup solo and it still tripped.

I suppose you could plug it all in to another circuit and try again.

If the psu was defective and had a short inside you would get a tripped breaker.

 

[Doctor Rob]

with the equipment that you have you would not be puling anywhere near the 15Plus amps.. liek the other person said.. are you sure you set the power supply to 220 / 230 V instead of 110 / 120? it matters..

as for if you had an 15 AMP breaker on your 230V that is around 3,450Watts max so with your 16 amp you should get even more output from the wall socket before it blows.. SO when you say FUZE.. you must be then according to your other post.. be the fuse or breaker panel at your house and not the computers power supply fuse.. IF you have everything unplugged except that power supply its the power supply having issues.

SO in short get a different power supply. OR you have some very bad wiering.. OR you have not selected 230V on the power supply and maybe that is causing issues. There sounds like the power supply is shorting out causing the breaker / fuse to trip / fry.

MERGED QUESTION
Question from 1994dominik : "does a fuzeblow damage your system?"

im building a pc right now and i wanted to ask(it happened) if the fuze blows on a pretest damage the components? it happened when the cables from the powersupply are connected to the parts and the powersupply with the plug and when i switched the powersupply to on it caused a fuzeblow! i asked if the psu is DOA. have acorsair rm850x white!
ANd i got an answer that it was the breaker that blew and have another question about an answer that i got:

The PSU can't be DOA because it tripped the breaker. You are are just pulling too many Amps on that breaker. Typical household breakers are 15 or 20 amp. If your's is a 15 that would explain why so little electronics would trip. Remember you have to calculate any lights and fans into your power/amp draw.

My next question:;
i looked its 16a

is it only cause i have 2pc on one breaker?

cause i could for the time being use extention to get power from a other breaker and when the transfer is complete just hook my new pc to the breaker in my room. when i pretested my system i once did it with the old pc on and one time with the pc off, but ididnt turn off the switch on my old pc so it still draw power that could be the reason right? besides my old pc is hookes to a very old powerstrip!

That's the biggest load of crap I've ever heard, well, almost ever.

First, don't EVER use an extension cord or power strip to plug your power supply into if you can in any way avoid it. If you HAVE to use an extension cord, use the shortest one possible and make sure that it is at least a 14 or 12 gauge cord of good quality and do not branch it or plug anything else into it. Whenever possible, plug your power supply DIRECTLY into the wall socket unless you are using a UPS system and then plug THAT directly into the wall socket and plug the PSU directly into THAT.

Don't use a power strip unless it is a very high quality model by companies like Tripp Lite, Eaton or Leviton. Avoid inferior products by companies like Belkin and Monster and for sure don't ever use power strips that are branded Amazon, or come from Walmart, Dollar stores or most home centers. Buy a quality model.

What is the EXACT model number of your power supply?

i tried with only the new pc and the monitor for boottest! but i havent unplugged the old computer from the plug! could that be it? that it still got energy and when i tested both of them tripped the breaker again?

and if a breaker trippes does that damege the motherboard and co?

sorry for my english im from germany
sorry im completly new to pc-building and dont have much knowlege! well i have used a extentioncable with a powerstrip! is it that not good? i have to use a extention cause the pc is 3 times wider away than the powercord gives me!
and can tripped breaker damage my system?
i have a powerstrip with overvoltage protection, kids safety and whatnot!
and maybie the breaker blew cause i still had my old pc pluged into the plug
i would try to test it again but im afraid to damage my parts(tried to connect the powersupply to the powerplug with out connecting to the motherboard and no breaker blew)

Yes, having two computers connected to one outlet could definitely, POSSIBLY, be the reason. Disconnect the other unit, make sure your power supply is selected to the proper voltage unless it is a unit with active power factor correction that does not have a switch on the back for setting the proper voltage AND also give us the model number of your power supply.

It's also highly possible that you've plugged something in wrong to the motherboard. Missed a pin or plugged something where it doesn't belong. That could easily blow a breaker and even damage your PSU or motherboard.

i got the rm850x from corsair! i cant change the voltage there! and i checked
i plugged the 1x4+4 and 1x4 cables that were called cpu into the sockets for the cpu( i have amaximus XI code) at the top! i connected the 24pin( dont know if i can even acieve to plug it in wrong and plugged 2x6+6pin pcie into the gpu(2080 ti)! but i found one odd thing the pcie need olny one 8pin connector to the powersupply! at the caable tehy split up into 2X6+2 cables

and afte the first breaker blew and i turned iot back on and tested my motherboard the first time i got errorcode A2! is that connected ot did i recieve a motehrboard dud? i tried every variable( from bare minimum to maximum 1xm.2 and one darddrive)

and i had a extention 2m cable witch hs the Certified safety seal and was testet by TÜV( german Testing organization security checks) can i use that? they are from Vivanco Schuko! or can you recommend a good brand?

and oen thing to add my speaker old pc and 2 monitors are hooked to areally really old powerstrip! can the old powerstrip can cause the energy to give wrong volts?

 

[Darkbreeze]

An old power strip can cause all kinds of problems from weak power delivery all the way up to the system shutting off, or anything in between. Make sure the PC is plugged directly into the wall, with no speakers or anything else on the same outlet plug in, and see if you still have problems. Do not run another PC off the same outlet.

 

[geofelt]

Is the outlet grounded properly?
There are some inexpensive testers that can check.

the old pc is plugged now into the the wall but it tripped the breaker again( put the old powerstrip away)!

thanks for this i will try! it definetly is the poweroutletproblem that has the problem! no test of new pc and when i put the old one in the outlet booom breaker away!
