Topic: An blackout can kill a mining rig??? (Read 389 times)

I have blackouts literally 2-3 times a day minimum haha. Been mining for months and its still going strong. Just have to enable power on after AC so it automatically starts your miner again.

Have had blackouts happing to my rig twice.
The first one screwed up my rig so it didn't boot to OS. Easily fixed by clearing CMOS with the jumper on MOBO.

The second time had to just pull out all the cables that go to the electrical outlet. Plugged them back in and everything worked again. Don't know why it didn't boot before, maybe had to drain some capacitors before boot was possible, don't know.

Blackout won't kill your rig, just gives you some unnecessary hassle

An blackout can kill a mining rig, I do not think there is any influence, because even though the power goes out mining is still in the wallet even though we have to repeat the mining from the start

Indeed, you just need a surge protector and you'll be good to go

Incorrect.  A circuit breaker only protects from over current.  It is an overcurrent device. Not an overvoltage device.

firstly you must got good AC for your rig

your card temperature must 70C or down

if the electrical  many time of

you can make your rigs run after the power return

you can do that from the motherboard bios

AC after power : make it enable

If you have good circuit breakers installed then you won't have any issue with yours rigs. They fill protect you from any power surges.

Off topic: Since you mentioned you are living in a tropical country, you need to also worry about cooling your rigs too. What setup were you thinking to use for it?

A blackout can't really destroy equipment. The worst is usually data loss. However since it's a mining rig then it's no big deal just reinstall everything from scratch or keep backups.

The bigger problem are brown outs. Browning happens when the voltages lowers itself to unsafe levels like 90volts.

Basically regular electronics like a fan isn't affected, it will just run slow. But computer equipment with capacitors are an issue because with a lower voltage the current compensates and it ends up essentially rushing large amounts of current which causes most of your electronics to fail.

You do NOT need a surge protector for an "outlet voltage that is not stable".  The ATX power supply will handle well over 240ac input.  Read the label on it.    It already has surge protection built in.  The computer which actually runs on 12vdc and less (CPU and memory is less) is isolated from the incoming 120vac (or even 240vac overseas) by design since there are a few stages that are isolated via transformers within power supply during the conversion from ac to dc in the power supply.  So essentially it would take lightning to jump the electronic gaps within the power supply (Transformers, diodes, transistors, mosfets, etc.) The power company is not going to jump those gaps UNLESS some moron some how managed to get a cross country power line connected to your house grid! Which is not likely to ever happen.

Please read with care.  Now more numbers.  A 1500 joule Tripplite means it only absorbs a paltry 500 joules and never more than 1000.  A surge that tiny is routinely made irrelevant by protection already inside appliances.  So what has that Tripplite done?  Nothing useful.

Also read this with greater care.  Effective protection means direct lightning strikes without damage even to a protector.  Routine are direct lightning strikes without damage - even 100 years ago.  But that means learning well proven science.  And ignoring lies, myths, and propaganda.  Effective protection will always answer this question.  Where do  hundreds of thousands of joules harmlessly dissipate?

Protectors from other companies known for integrity means a protector remains functional for many decades after many direct lightning strikes.  These protectors cost many times less - about $1 per protected appliance.  Companies known for integrity include Intermatic, Square D, Ditek, Siemens, Polyphaser (an industry benchmark), Syscom, Leviton, ABB, Delta, Erico, General Electric, and Cutler-Hammer (Eaton).  A so expensive Trippite is not in that list.  Its near zero numbers even says why.

If using a Tripplite, then damage from lightning is even made easier.  You have zero reasons to believe a Tripplite does anything useful. In fact, if found in your luggage, it may be confiscated by a cruise ship.  They also take fire more seriously.  Fire is another problem created by near zero joule protectors not protected by a properly earthed 'whole house' solution.  And yes, that solution means direct lightning strikes without damage even to a protector - today and over 100 years ago.  Is that clear enough yet?

Completely different is power provided by any power strip - with or without protector parts.  Shape of that AC receptacle says it can provide up to 15 amps.  Power strip's circuit breaker also must be 15 amps.  If a wall receptacle can provide sufficient power, then a power strip also can provide that power.  Those numbers are completely unrelated to separate circuits that do surge protection.

If a power strip does not have a circuit breaker, then it should be removed as a threat to human life.

Last two paragraphs are completely irrelevant to surge protection, brownouts, or blackouts.  A human is always expected to perform some arithmetic.  Sum of currents draw by appliances verifies that its circuit breaker will not trip.

All this stuff is layman obvious.  Unfortunately too many eyes glaze over with each number - not an exaggeration.  Concepts even taught in elementary school science are implemented so that your telco's CO (switching computer) suffers about 100 surges with each storm.  How often is your town without phone service for four days while that computer is replaced?  Never?  Exactly.  Because protection from direct lightning strikes is routinely found in every town - today and 100 years ago.  And completely unknown to so many educated by outright lies and myths - such as those from Tripplite.

Protection from lightning is impossible only when one has swollowed the lies from Tripplite and equivalent (high profit) manufacturers.

Again, a Tripplite or equivalent plug-in protector can even make surge damage easier.  As we demonstrated by tracing surge damage even by replacing each damaged semiconductor.  And explained it in design reviews.

Informed consumer uses a solution that always answers this question.  Where do hundreds of thousands of joules harmlessly dissipate?  A protector is only as effective as its earth ground - today and 100 years ago.

Same applies to blackouts and brownouts.  Those do not harm any properly designed electronics.  Brownouts are a concern for motorized appliances - not electronics.  How often this week have you replaced less robust appliances - ie doorbell, GFCIs, smoke detectors, microwave oven, central air electronics, clocks?  Are those protected by invisible protectors? Best protection at each is already inside each.  Miners are even more robust.

Then discuss what can overwhelm that best protection - always with numbers.  We have not even begun to discuss effective protection because so many fables first must be exposed - with numbers.

Start by admitting protection from direct lightning strikes is routine.  Even that expensive and near zero joule Tripplite must be protected.

Yes, strong enough to support the rig. As i said if you're pushing too much power through an underrated surge protector or power strip it will pop the breaker in it. That's moving backward at that point.

A middle of the road tripp lite protector is good to the ball park of 1500~ joules, and yes as you said, if lightning strikes too close it doesnt matter what type of protection you have, anything is going to get fucked regardless. While the topic is about blackouts and equipment, surge protectors are good for other reasons beyond that.
Surge spikes by running too much power at the wall, old houses and out of date wiring, could help prevent fires. Not everyone lives in a modern society where every house or building they enter is up to date in wires and electrical circuits and breakers. (Even in the states)

Sometimes i leave a little wiggle room for an inquirer to do their own reaserch, so pardon my lack of "spec numbers".

Even under bitmains list of reasons of voided warranty it's stated:
"b. Damage caused by poor power supply, lightning or voltage surges;"

So if your home or facility faces any of the problems i stated above and you tell bitmain "i lost power during a thunderstorm and my rig doesn't work anymore" they're gonna tell you to kick rocks.

You seem very well versed in this area (much more than i am). While protection against close lightning strikes is damn near impossible, there are a number of reasons they are necessary and saying they're not is like saying that since its not 100% guaranteed a condom will prevent inception of offspring and contraction of STD's, im not wearing one at all.

Define 'not stable'.  A subjective term - an indication that a scam may be promoted.

Voltage can drop so low that incandescent bulbs dim to 50% intensity.  That is perfectly good voltage for all electronics.  Computers work just fine (are required to work) even with a lower voltage.

Voltage can rise so high that incandescent bulbs double intensity.  That also is perfectly good voltages for all electronics.

Those same voltages can be problematic for motorized appliances. So motorized appliances desperately need that protection?  Long before PCs existed, AC utilities had to provide sufficient voltage - or cut off power.  These standards existed long before PCs and long before most who have posted here existed.  But fears, myths, and subjective claims live on.  Because so many only feel it must be true.

Anyone can read a let-through voltage in spec numbers.  Again, most simply ignore numbers to somehow become knowledgeable.  A 120 volt protector may have a 330 let-through voltage.  That means a protector does absolutely nothing until 120 volts rises well above 330 volt.  Where is this protection so hyped subjectively?

Best protection at each appliance is already inside each appliance.  Numbers posted previously.

Just as bogus is a destructive blackout.  If destructive, then an 'at risk' part will be identified.  Nobody will.  No part is damaged by unexpected blackouts.  Only fear and other emotions justify that belief.  However, the challenge is blunt.  If blackouts are destructive, then one must cite that 'at risk' part.  Or admit to having been manipulated by hearsay, wild speculation, and advertising - also called brainwashing.

Defined is what anyone does to protect from surge damage.  Since even a Tripplite and other magic boxes must be protected.  Then superior protection already inside every appliance (defined above with numbers) is not overwhelmed.  If a miner needs that protection, then everything needs that protection.

Use only power surge protection when your outlet voltage is not stable to reduce the overflow voltage. So, surge protection could help  reduce the risk of any parts of your miner.

however, if your miner is always shutdown every time your area is blackout without shutting it down your miner can  damage unless if you are using other bootable OS like ethOS or smOS these OS that I know it's safe for blackouts Also, I suggest you if you are using h110 btc pro you can set the bios to auto power on everytime your miner shutoff.

It has to be strong enough to support your rig?  How many joules does that Tripplite claim to 'absorb'?  Hundreds?  Thousand?  Potentially destructive surges can be hundreds of thousands of joules.  How is a near zero Tripplite strong enough?

As others have accurately noted, blackouts do not harm hardware.  Surges occur maybe once every seven years.  If a surge does exist, then everything (most that are less robust) must be protected.  Protection is also desperately needed for a dishwasher, dimmer switches, furnace, LED & CFL bulbs, refrigerator, door bell, recharging electronics, garage door opener, GFCIs, central air, every smoke detector and that near zero joule Tripplite.   How many have been damaged by surges this week?

Blackouts do not damage electronics.  Brownouts may be problematic for motorized appliances.  120 volt appliances, before PCs existed,  would withstand up to 600 volt transients.  Many electronics today are not damaged by thousands.  But everything remains at risk if one has not properly earthed a 'whole house' solution.  Only that has numbers that define actual protection.  Tripplite clearly does not.  So that recommendation did not include the always required spec numbers.

Protectors do nothing for blackouts or brownouts.  Each is a completely different anomaly.  Did solutions exist for each anomaly.  Obviously, any recommendation must also include spec numbers that say why it works and by how much.

No problem, just set AC BACK Function on the motherboard and continue mining.

Absolutely right, BlackOut only affected the motor electric (HDD will affected), as long as you are using SSD, you was on safe. The one that's risking your rig is BrownOut.

Yeah, surge protector may be needed for safer.

better to make electrical storage. our blackout compass is ready with our own detrimental conditions.

Oh, the 'ol computer-breaking non-proper shutdown thing.
This is because of old Hard Disk Drives spin can't be stopped in the middle of the operation.
If it happens, the data might get corrupted or worst, bad sectors.

Most mining rigs however, uses SSD which is far less vulnerable to data corruption by power loss.

If you are using SSD, a surge protector is good enough.

All depends on the fault that caused the power outage.  Its quite possible the power (voltage) goes up during a serious tropical storm because of substation and other types of more local to you faults in the power grid.  Ive seen a U.S. home have 290v when it shouldve been around 240v.  This causes both 120v legs to be around 145v+ which pops all the lights (incandescent at the time) and took out the tv and some small appliances.  This was caused by a drunk driver hitting a power poll down the street which had the local block transformer on it.  The power supplies (ATX) for computers are made to handle substantial power spikes.  In fact most all though plugged into 120v will run just fine up to and over 240v. The power supply will make up for substantial lower voltage for awhile also. The specs are labeled on each ATX power supply to show what they can handle.  The sudden loss of power will not hurt your system. Might screw up windows o/s but can be recovered from.  A UPS big enough to power everything during an outage would cost a fortune!  Would be totally useless if the internet was down which is likely if the power is down because of a storm.

All bets are off when it comes to lightning which is a "surge".  Lightning takes ALL paths of resistance and does whatever it wants. It takes 10,000v to jump a half an inch air gap.  Lightning is going between the sky and the ground...you do that math!  

Power surge don't do any damage at all. if something dies because of it then blame the components of the product.
