Yea, good luck with your H110!
In my case I switched back to Asus because I could not figure out the issue with its on-board NIC which was hanging up and wrecking my LAN and attacking/DDOSing my wifi router every other day. First I was blaming bad Linux drivers but then reproduced the issue in Win10 and just returned the board. Hope it's resolved by now with new Bios or NIC chip rev.
Topic: 2400 watt Server PSU on Asrock H110 PRO BTC - NEED HELP (Read 409 times)
Thanks, you saved me a lot of headaches, I have 5 of these boards arriving any day now, and I had totally missed this information.
In my experience with H110 from the first batch, I remember having to plug in both 4-pin Molex connectors. Not sure whether they sense the 5V or 12V line voltage levels, but they definitely require both connectors to be powered.
Now, since you are using powered risers with 6-pin power going from the Delta to them, they will themselves "generate" the necessary 3.3V and 5V power sources for each of your GPUs and the motherboard will not see much power load going through PCIe slots if any. Therefore you should be able to split your only 4-pin Molex coming from the PicoPSU into two and plug them into both connectors on the motherboard to satisfy the logic requirement.
In my case I was getting POST Error 99 once I had more than two PGUs installed and when only one of the auxiliary molex connectors was receiving power. There was no Bios setting available to disable this logic available or I was just not looking good enough.

I can confirm you only need 12v on the 4 pin power connectors to make this work. I have over 100 of these boards with PICOs and PCIE 6 pin to molex adapters to power the board.
Ok. So both 4-pin connectors on the board has to be connected, but not the SATA? Is this also true if using only 7 cards with powered risers? Can they be powered directly from the server psu or must they be connected to the pico psu?

Any ideas? I just loaded each cards individually to make sure every card is working separately and it is, so it basicallly all the cards and risers are good, it’s just the pcie connector on Mobo error msg when I try more than 2 cards

Using parallel miner pcie powered risers wired directly to server psu, 1 wire per riser. Video cards also have a single wire from from server to 6 to dual 8pin adapter since zotac 1070ti extreme use two 8 pins on top.
What type of risers you are using, if they are powered by the delta psu and you are using also powered riser on the 16x slot then you can simply disable the extra connectors from the bios. Been running for months without them
I purchased a delta 2400watt psu to completely power my current 6 gpu rig so I can expand in future. I am using Asrock H110 PRO BTC motherboard and bought parallel miner 180watt ATX adapter for 24pin and cpu power connections.
I assume my issue should be the same for anyone that build a gpu rig with the H110 BTC using only a single server psu for everything.
So after trying to initially run smos from USB and failing, later finding out it was due to some bad cables, I bought a 120gb ssd and installed Windows 10. I finally have everything running and updated with 2 gpu cards (1070ti). The issue is when I try to add the 3rd gpu (adding one at a time), I get immediate message “you must install 4pin PCIe power”, and can’t proceed.
The board requires 3 additional power plugs on boards to be powered, 2 PCIe (4 pin Molex) and 1 SATA power. The 180wattt ATX adapter I purchased from parallel miner comes with a peripheral wire that has a Molex and 2 SATA power, of which I’m using one SATA for SSD and other for power connector on board and not using Molex.
To power PCIe Power connector on Mobo, I’m using two PCIe to Molex connectors straight from breakout board. The only issue I can think of, those PCIe to Molex only include 2 wires and the pinout in users manual label that 4 pin connector having a detect wire which is the red 5v wire, 2 grounds in middle, and 12v, I only have one ground and the 12v.
This is 180w adapter

So my main questions is do I need just 12v at the PCIe power 4 pin Molex on Mobo and the issue is with something else or is it not detecting power connected to piwithout the 5v wire? If that isn’t the problem, what could it be?
If I get a Molex wire splitter and use the wire from adapter, that gives me all 4 connections needed, but that very small adapter wire is then powering 4 things, the SSD and all 3 Mobo plugs, is that too much draw?
If the missing 5v wire is the issue, can I leave the existing 12v PCIe power in place straight from breakout board and just add the 5v wire to that Molex plug using the ATX adapter red 5v wire? If
This is my first rig and it’s been a nightmare so far, but I’m in the home stretch, any help is desperately needed.
