I agree that server PSUs are the way to go, both for the value and for their longevity. Server PSUs were actually designed and built for this kind of 24/7 operation, whereas some of the lesser consumer PSUs assume a typical low stress 8 hour day usage pattern. As a bonus, at 240V operation, server PSUs are often just as efficient, but at a small fraction of the cost, as the Platinum or Titanium consumer PSUs

While both types obviously work for mining, I think server PSUs are the best value because of the above reasons. Also, the breakout board can cost as much as the used server PSU, so oftentimes new miners are put off by this. Just realize that if a used PSU dies, all your wiring and breakout boards are probably fine and you can simply swap out the failed PSU with another $20 used one versus having to RMA the consumer version you bought new as well as the re-wiring of everything.

Correcting the title : don't be cheap...

The only "cheap" solution is server PSU with breakout board but with at least 15% more power than you need. You can get a 1200w HP PSU for 60€ plus breakout board 10€, plus pico psu 15€ plus the cabling 30€ => 115-120€ for 1200w which is 50% of the price of a classic computer PSU for the same wattage in platinum rating but you have a bonus : noise :p

My power supplies cost $7.50 each for 675watts. Is that too cheap? :p
Used server psu pulls work just fine for mining, especially if they run off 240vac with better than 90% efficiency. The only worry is the electrolytic capacitors and fan life. Refurbishing all of those parts costs less than $10.

You forgot to say the most important thing which is ground the psu socket. You trolls never do anything right.

1000w isn't necessary. Especially if you're running two PSU's. It's more important to understand what loads you are pushing on each power supply and to keep everything under 80%. My 9 GPU rigs of 1060's pull 800 watts, but I use 2 x 750's.

lol and yes as the above poster said it's gold rated. Don't feel like slamming the OP's video because I appreciate the effort but more important to share the right information instead of just trying to put something out there to gain followers.

I believe it's gold rated, not gold plated, lol.  And platinum rated are even better at efficiency.

I always physical watt meter device to check usage as im not sure how accurate the figures are in GPU-Z etc

yes, I agree with you. I always using measurement tools. I have some case, where power consumption on AB have many gaps with the real power consumptions (at the wall).

The best thing about Rig Powering is knowing about powering itself, knowing your devices, knowing basic electricity (cable type, power consumption etc). And always calculate how much power that your Rig needed and give them power spare. More wattage is safer.

Power supplies, you can get them to run or whatever, don't buy anything under 1000w, this is what I have learned now I've learned now that 1000w PSU's are the way, gold plated if you can, get an EVGA gold plated PSU's then you should have no problems with getting majority of graphics cards
