Topic: Server PSU or ATX PSU? - page 2. (Read 3387 times)
Why do only HP server power supplies are being user on mining? Is that because they have a slot where to attached breakout board?
Final question - do all server PSUs have the same connectors where the breakout board connects - or does each manufacturer (Dell, HP etc) have different connector?
There is many many different connectors.
Main difference from server and ATX psu - server PSU have only +12V output
Does anyone know where I can buy some breakout boards in Europe?

Only ATX!
Does anyone know where I can buy some server PSU's along with the breakout boards and ITX connector in Europe?
question for those running those HP "1200W" power supplies (that are actually only 900W at 120vac),
how hard are you pushing them?
I only have three GTX1070's on one right now and it's already hot as hell, can it actually handle 900W?
to answer OP's question about switching, you can get fancy and rig up something to switch them on at the same time, or do what I do: just switch on the GPU's a second before the main system

I've read that you can get PICO PSU - something like https://www.amazon.co.uk/d/Power-Supplies/Mini-Box-picoPSU-160-XT-Power-Mini-ITX-Supply/B005TWE6B8 which I guess somehow you connect up to the breakout board - and then the server PSU powers everything? Anyone use this setup - and know where to source in Europe/UK?

I think that you can go with the server psu. For the rx series you will need 6 cables with two 6+2 pins so that you can power the card with one of the 8 pins and power the riser with the other end of the cable. You will need a version 006C for the risers. It's very clean and the less you joint cables the better.
and also you can use PCIE Splitter cable so one GPU only use 1 PSU's cable, and (for GPU+Riser) its safe assuming splitter cable at least use 18awg wire

Is there a maximum recommended watts per cable from the breakout board - to ensure the GPU+Riser with the splitter cable don't overload things?
Personally myself i prefer server psu, for the a good reasons stated above, i agree its more tolerant to environmental conditions vs PC ATX.
I also agree about margin, never load PSU to above 80% not critical, but certainly truly stresses it if you go above.
Breakout cable is not a problem.
There are server PSU's that can handle over 200A on 12V rail - im not aware of any PC psu that can handle that (some IBM BLADE's for example) they have some funky nreakout adapter-cable, but hey ....200Amps..
)
any recycling company just trashes those HP/DELL/IBM power supplies and will sell them to you for like 15-20$ a piece in working order, so no competition near, i just buy 5 right away and if need arises will swap... just seen a couple times when psu swap was needed.

atx psu are better they offer surge protection, they are also more plug and play and less hassles, but they cost more, personally i would go with atx, saving $200 is not that important now with the current profit, you can roi in the same time
You want at least 20% margin throughout the power delivery setup, including the PSUs.

im standardizing to 1500 watt rosewill quark psus so i can dusl mine
they have a ton of cables for up to 8 gpus and are way quiter than server psus
also they have next day replacement inly company that will send rma withoute reciving damaged
units back and a 10 year waranty. they will hold thier value too when mining ends

A consideration: often server psus are very loud (if that is relativant to your environment).
The HPs I have worked with are pretty quiet. Almost certainly quieter than the mining setup you'll run with them.It all depends on how much load you put on them. For example, if you are pushing the HP's server psu near it's limit(close to max wattage), it's like a screaming banshee. But if you are only using about 30-50% load or so, then it'll just be humming.

In my experience, surplus server PSUs are so cheap that when you can easily buy 4 or more for the price of an equivalent ATX unit, warranty doesn't really matter. Just keep a few spares on the shelf.
ATX
- its more expensive
- not designed for 24/7 (but its not a problem anyway just wear off faster)
+ its more safe (more protection, covered by 80+ standard, designed to work on wide working condition) <-- this is wrong. Servers PSUs are covered by the same standards and are almost assuredly more efficient as a general rule.
+ covered by long warranty
+ more availability
+ does not need custom breakout (all ATX standard)) <-- You do not need to buy an expensive breakout board. You can build one your self with an $8 soldering iron and some PCI-E pigtails.
Server
- less safe (less protection feature than higrade ATX, had strict working condition requirement) <--Not true, server PSUs in general have BETTER protection circuitry because they are powering devices worth tens of thousands of dollars.
- warranty ? (its complicated to claim RMA)
- less availability
- need custom breakout cables
+ designed for 24/7 with server grade room condition (temp and humidity) <-- in my experience server PSUs can handle much greater heat loads. I have even had servers PSUs sprayed down by a damaged misting system that did nothing but shut off until they dried out.
