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.

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

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

 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.

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?

So true, the competing factor still a big thing.

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.

 Looks like an "overloaded cables" issue.

Also worth noting that most (if not all) PSUs do show their best efficiency at approximately 50%-60% of their maximum rated load capacity.

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?
