have you looked at server psu rigs and picos?
Yes I did consider this option, but:
1. Its very hard to get your hands on high power server PSU. Does HP even make them more than 1200w? And ones I have seen look like are two PSU`s combined together anyway. They just look like one.
2. Break out board is extra point of potential failure +god knows what quality are they.
3. PICO is another extra point of failure.
I prefer least possible hardware components in the system.
yes hp does make a 1500w server psu, there all over ebay and its not just hp either, theres also dell ones too that are common slot as well, along with many other brands, just takes a little research but that seems to be more than the average person is willing to do
no one has mentioned one ever failing, atleast not that ive seen yet. while id bet there has been. theres always a reason why it happened
only time ive herd of pico's failing is if there overworked and cheap
as it stands the only real failure point is the cables, a good properly set up rig that goes by the 80 percent rule with the psu and pico atleast should get lots of use before it fails
couple of my rigs that I have, there set up using server psu's they run great and man I gotta say the less cable clutter is awesome looks soo much cleaner than compared to using an atx psu, but I also custom make my own cable for my rigs since I have all the crimp terminals and plastic connectors for eps 12v, 6 pin, 8 pin, 6+2 pin. didn't like what I saw as far as what can currently be found, that I know of still only myself and one other person makes such a cable to power a pico and eps 12v using 1 cable
btw using server psu's is also a price point in some cases, not so much with the hp 1500w psu as it has gone up in price since 5 months ago, but for instance I just bought a dell 1400w server psu and breakout board for a whole 74 dollars compared to spending what like 250 to 300 dollars for the atx version, sorry in some cases I could buy 2 of the server psu setup for what one would spend on a high wattage atx psu, btw the server psus we use for mining are all pretty much platinum rated the hp 1200w has a variant that is gold rated and one that's platinum
