Topic: Parallel Miner 2400w PSU - questions / input requested (Read 5453 times)
Looks like Parallelminer/Centrix-Int bumped up the price from $60 to $160 - and supplies are limited. Where else can i buy these PSU's?
How do you trigger reboots with this 2400w PSU and PicoPSU (ATX) adapter?
Does the power switch jumper on the Motherboard still reboot the system or do you have to use the button on the breakout board?

Motherboard switch still does it.
The button on the breakout board turns it on and off as well.
Be aware... I can't get this working with a Biostar TB250PRO motherboard.
I had a similar problem with a couple of PicoPSUs out of ten on Asus Z270E boards. Replaced with a similar 160W pico from a different source and it started to work. Haven't had a chance to investigate much further but I don't think it was the motherboard issue. Could be a combination of factors...

Just out of curiosity as i'm using that same 1200w psu and breakout board. Is there a way to bypass the push button on the server board so that the psu always comes on when power is applied? Right now I have it powering my gpu's with a 650w evga powering the risers and mobo stuff, but if it locks up and I want to power cycle it remotely I can't power cycle the whole rig, I have to just control the power to the atx psu. There should be either a way to bypass the button and make it always on, or tap into the signal from the atx psu and make it sense when that psu turns on.
You can leave the server PSU on during restarts. I haven't had a problem with it.
I haven't found some way to tie them together, unfortunately.
DeepInTheMines just started selling a different breakout board. It looks like it has a floppy 4-pin connector (use Molex adapter). I havent ordered one, but i was looking for a similar solution, and this might work.
At less than 40% load, not bad at all (GPU's make more noise generally speaking). Once you get around 70%, those tiny fans start getting up there in rpm where you notice them, but they don't really start to "scream" until you get past 80%.
out of interest how noisy are these?
2400W GPU kits’ prices back to normal : from $119/$159/$189 to $181/$225/$249

you can roll with atx's I use them on my lower power builds.
but once you get to a 1200 watt and up build the delta 2400 watt servers are better.

one thing I do find a breeze with server PSUs is indeed the connection management. you can go all 6pin risers (no Sata, no Molex), buy them in bulk and there is just less mind computions for managing PSU setups. with ATX you can always some connectors or pin cables depending on the brand & models you associate so there is more studying to undergo prior. some buy ATX based on power capacity alone then realize the units are not equipped properly for their rig need
many atx have this issue.

So I've been waiting for Finksy to start selling his power supplies again.
I have one of each of these power supplies from ebay. I have only had a chance so far to run the 2,880 one and it works quite well. In the ebay description they mention that they aren't a fan of power supplies with breakout boards and that connections should be soldered.
For those that have the parallel miner PSUs, how do you think they are compared to these two ebay power supplies?

Are there long-term miners on server PSUs around here ? How long has your server PSUs been lasting ? Average time before going dead ? Got early deffective ones ?
Due to their almost non-existent warranty time (30 days), I am skeptical to choose them over ATX PSUs which have 10 years warranty as I fear I might need to buy numerous ones over the span of few rigs lifetime cycles, then I am not so sure about actual savings, all things considered (reselling of ATX replacement units of never models in the long run)

They should last longer than consumer grade PSU's. These are designed to run 24x7 for years on end in servers after all.
well, after query, server PSUs' (refurbished!) resellers are eyeballing a longevity of 1.5 years - 2 years, not more (with some rare cases less than 1 year or above 2 years), past any warranty time in all cases
therefore, considering :
- twice units of server PSUs favoribly run closer to 50% load rather than 90% (ATX)
- zero resale value of server PSUs (dead units) against a resale value of 30%-40% of ATX psus, eventually from a newer model of a replacement during the 10 yr warranty time around year 4-6
- despite a 3% efficiency boost in favor of server PSUs underloaded
...the attractiveness of server PSUs does not look evident
actually in my case (considering electricity costs, shipping costs, etc), ATX psus would appear more cost effective from year 1 to year 10, no matter how I manipulate the figures
(side story, you don't see a giant cloud mining company like Genesis running their GPU rigs from server PSUs but from ATX. Was it studied ?)

i never build big gpu rigs.
but I do mine some
avalon 721's
avalon 741's
bitmain s-9s
nothing seems better for them then the delta 2400 watt gear.
I pull only 1100-1350 watts per psu.
so psu is relaxed so to speak.
no atx really thrives at 1350 watts
I have run 1500 watt roswewill tokamak titanium
I have run 1600 watt evga titanium
I have run 1600 watt evga platinum
I have run 1600 watt evga gold
I have run 1500 axi platinum
none of them really do well on the antminer 14th s-9's

Well, actually if you check some of the newer Genesis Mining DC tour videos you will notice them using HP server PSU's to power their rigs.

I concur with Phil on Delta's reputation and reliability. It's one of the largest OEM's in the world for industrial power supplies. Most of HP or Dell servers use Delta PSUs and they have been doing it for decades.
I've been dealing with servers (and designing server configurations) for a living for quite some time and for the past 10+ years our typical annualized failure rate (AFR) was less than 0.5% based on many thousands of servers. This 0.5% AFR figure means that if you have a 100 servers and run them 24/7/365, you will end up losing less than one PSU every two years. Most servers use redundant PSUs, so they stick two of them and run at 50% load. In an unlikely event of a single PSU failure, the survivor will be able to sustain 100% load for a long time (days/weeks) with no issues.

These Delta's don't seem to like being pushed much past 1800 Watts. On my 8x 1080Ti rig, I changed power limit from 190W to 210W, and after 4 hours, it shut down. Miner went offline since I forgot to set the BIOS to power on after "power failure". Guess I'll pick up some more and run 2 on my 8+ GPU rigs after all.
As Phil pointed out, this is still way cheaper than large EVGA units, and as SCSI2 pointed out, more efficient. I'll make some custom dual C19 power cords to keep things neat.
some 1080tis go rouge and do 100% tdpAs Phil pointed out, this is still way cheaper than large EVGA units, and as SCSI2 pointed out, more efficient. I'll make some custom dual C19 power cords to keep things neat.
When set lower.
My aorus 1080 ti would often go to 300 watts. Which is its 100% tdp.
It is possible you were pulling more then 2200 watts.
I ran two Avalon 741 pulling 9.8 to 11 amps of 240 volts.
Got hot but kept running.
I now use two psus and the fans are much quieter.
I prefer these to the Evga as I can get three deltas for one Evga 1600 plat

delta is one of the best psu builders around.
I have five so far.
but I don't push them as they are low cost
130 for 1
vs 300 for an evga 1600 gold
or 379 for an evga 1600 plat.
