Topic: Don't focus on GPU panic. Focus on efficiency. (Read 2119 times)
I've been searching this forum for a good advice in mining especially gpu mining. I do want to build a rig someday to farm some profitable tokens. Upon reading your thread it covers most of the questions in my head such as buying 2nd hand gpu's, what is a better psu to use and power or efficiency. Nice thread OP! I'm saving up to buy some gpu's do you have any recommendation for starters?
Also worth noting that most (if not all) PSUs do show their best efficiency at approximately 50%-60% of their maximum rated load capacity.
Wow, that is scarry!
How could this happen? Everything in PC world is usually made of non burnable materials.. cables etc, or at least should be! Do you think it was some respectable brand of PSU? Or did it caught fire from PSU at all?

Looks like an "overloaded cables" issue.

You have to be very careful, I saw a guy on a video putting things close to the psu and other components that catch fire. You should never do that. The place you are mining should be zero contact with anything else and needs to be a larger room and most important you must distant them from other things.
Most Gold rated power supplies do noticeably better than 89% efficiency across most of their rated power range - EVGA and Seasonic in particular usually just MISS "Platinum" rating on their G2 and X series power supplies.
Also, long term you aren't likely to be profitable at 10 cents / kwh - the last few months have been a noteable exception but NOT the norm - since most of the BIG farms are paying less than 5 and commonly closer to 3.

So true, the competing factor still a big thing.

There's also a good ROI on platinum/titanium psu. Imagine gold psu = 89% efficient, titanium = 94%.
The psu is 1500W, and you use 1200W. 5% efficiency difference is ~ 60W lost.
60W over a year = 60*24*365/1000 = 525KWH wasted due to poor efficiency.
If your electricity rate is $0.10, thats $52 lost. Over 5 years, that's $250 due to efficiency loss. If you're in mining for the long haul, it makes sense to go for platinum/titanium psu

There is a lot of types of mining some very trusty while some are not so trusty but it depend on the person choice what he want and which quality he want. Mostly GPU have no good quality as you are expecting for which you can paid a very high price.
For the long run it is really important to also keep the cards cool with MSI Afterburner app to keep fans 60-80% and place the mining rig not in a hot place. Keeping cards cool prolongs their lives. Also the PSU is the most important part of a mining rig and I would not settle with anything under Corsair,Evga or CoolerMaster. Also you have to be patient and to not expect great returns nowadays, a rig with 6 x RX 580 can make 200-250 usd in a month and this is an optimistic prediction considering the profitability totally down from Gpu mining.
Is staking coins more profitable than mining coins at the moment? dollar for dollar?
I have yet to see a "staking coin" offer returns that beat a good Certificate of Deposit, much less a decent "high yield" stock.
They're not even in the same BALLPARK with PoW mining unless your electric cost is insanely high.
If someone's GPU rig caught fire, they were doing something SERIOUSLY WRONG with it's setup.
PC cases are ALMOST ALWAYS made of steel - aluminum is sometimes used on high-cost "vanity" cases but it's not the norm.
Keep in mind though that most serious miners don't use cases at all, as they add needless cost and hurt ventilation (unless you add HIGH AIRFLOW fans that soak a fair bit of power).
The person who want PSU then for a PSU I would like to prefer plat, gold and titanium rates psu these are a quality and branded and also a big profit is that it is efficient power supplies.
On small scale mining is considered less profitable due to the electricity rates. So if you have good efficiency that means output to input ratio than there is no need to pay attention to GPU panic.I am sorry for the guy that burned his miner, it is a shame ur investment is gone

Actually I feel quite to opposite, it is probably a good thing it caught fire but did not burn his house down. This will be a very strong lesson and reminder for him going forward to do things correctly and not cheaply. Imagine if that had started on fire in the middle of the night and say he has young kids in the house. While it may suck to lose a few pieces of hardware, the result could have been much worse.
Anyway, I also agree with the consensus that you should not cheap out when building a mining rig. Buy a quality name brand PSU and only run it at most to 80% of its capacity. Also same is true with the circuits feeding your miners. If you are in the US that means a circuit can only continuously operate at 80% of its breaker rating, thus a 20 amps breaker/circuit can only supply 16 amps of current. On a 120V line this would only allow about 1900 watts of power, so this could feed only two 1000 watt PSUs running at 800 watts (to system) and will probably draw 850 watts (at wall) or about 1700 watts. Keep this in mind as well when adding rigs to your home to help minimize fire risks.

+1 for the PSU part of the topic above. I couldn't agree more. However, I would like to add following: You system is only as good as weakest link in it. Now when it comes to mining rig you could think that is not so important but better to be safe then sorry.
I was fortunate to bump into my rig one night while passing trough basement. One line from power cable on one of the PCIE risers has apparently disconnected itself from connector and found itself next to metal (I think aluminum) frame of my rig. When I bumped it in the night there was sparks everywhere. After closer inspection I wound the wire and it already burned trough few milometers of aluminum. The rig was working normally and I was not aware of any problems and it could have burned everything down

Metal is only one material for rig case. Remember PC cases made of steel or aluminium
It should be added Do use ONLY flame-proof materials for your rig to:
If you are new to GPU mining here is my advice to you.
Do not pay high prices for GPUs with the promise of great returns.
Do figure out how to stack discounts when buying online.
Do not buy anything on ebay unless it is truly a great deal.
Do consider buying a good PSU.
Do buy hardware when people panic sell.
Do not fear buying used, but always buy newer models from companies where warranty transfers such as Evga.
Do your research on the best models to purchase.
Do not sell your coins after the panic. Sell during the rush.
Do optimize your miners. This will pay off in the long run.
Do expect a long ROI at around 150 days minimum. This is not a get rich quick scheme unless you were mining in May/ June. Be willing to learn how to trade coins to maximize profit.
Zcash is your friend.
For science I purchased a bunch of GPUs in June to add to my existing arsenal. These rigs are 75%+ paid off already. If I can do it, so can you. Any questions feel free to ask.

the price of gpu at my place drop arround $50-$70'i think time to buy gpu again?
This phone difficult to mass quote. What prices are cards? It may be time soon again if $50 off AMD.
Another thing is never reach the max hashrate of cards. Try to undervolt/ underclock to find the best efficiency of hashrate for long run. It will help rigs run cooler, longer, more stable.
Yes. Great example is I had this rx 570 8gb that hits 660 H/s on Monero while my rx 580 8gb gets around 680 H/s. To top it off the cards would stay around 43 degrees C which is incredible temperature while using almost 80 watts per card.
I'm new to mining, I just started mining the new Gopnik Coin for fun but I was told it's really not efficient because it is a Scrypt algorithm.
So if I understand correctly, I should be mining ZCash with GPU? I have AMD R9 280X, does this even matter? ZCash is the most profitable for all GPUs?

I believe that hashes around 170-180 h/s which is fairly decent. If you own any nvidia 10 or 9 series zcash all the way. Since you have AMD I would read around for several popular coins and calculate ROI based on other peoples tests.

I couldn't agree more to the list, especially the PSU part.
I'm currently running XTR850 80+ GOLD. PC draw 550W from wall so that is approx 65% of max power of PSU. In case I want to add more cards or buy more power hungry I would definitely change the PSU for stronger to stay within 70% of power draw.

I think the PSU like the heart. People or animal with strong heart will live longer for sure.

Try to research here https://bitcointalk.org/index.php?board=159.0 and you will find your answer. IMO, find new potential coins have best algorithm for your cards and low diff.
