Got something to discuss?

I would really like to purchase a board for private use, but shipping to sao paulo / brazil is too high, it was 40US
would it be possible to provide another cheaper shipping method?

1 month 26 days ago

I’m surprised Brazil is still a shipping option as we had so much trouble with the country custom process. You should check third-party shipping companies in Florida that offer cheap rate in bulk to Brazil. Then we can ship to them and they ship to you.

Dell D2000E-S2 0XYK93 was on X15 support list but not on X15 version B. Can you confirm that if it support this 2000w PSU?

It is compatible with Dell D2000E-S2 XYK93.

Got my order today and I’m in general a bit disappointed with this new breakout board.

First, it does not work on my power supply: E1100E-S0 (Dell P/N 0GDPF3) which is listed as “we expect compatibility”. The connector fits but nothing happens when I push the power-up button. I have a few identical PSUs and none of them work :'( The compatibility list needs an update for X15B. Let me know if you need more information on my PSU.

Second, the build quality is worse than other breakout boards (e.g., X12) I bought earlier. As you can even see in the product photos, many components are poorly soldered (too much/uneven solder) and there could be bad connections.

Hi Victor, please contact us via our contact page. We need to assess if the unit is defective or the PSU is incompatible. We will send you a tested unit so we can know for sure. Thank you

Thanks for the quick response! I’ve sent you a ticket 13271 with photos of the PSU and my setup. Hope we can figure out the issue.

Just got my X15BBRK boards. I connected the Sync (4 pin fan connect) cable but its working opposite of the instructions. Pressing the power button on one Power Supply Board turns off the other Power Supply and vice versa. I cannot get both to turn on at the same time with the Sync cable connected. Am I missing something simple?

20 days 19 hours ago

You are on a catch 22! One unplugs the sync cable. Two, power off all PSU. Three reconnect the sync cable and power the first one … The other will now follow and be synced

20 days 19 hours ago

Hahaha yep I figured it out right after posting. Teach me to play with them before using the sync cable. One had memorized powering up in off mode… so when I used sync I got the “toggle”. Unplugged sync, turned both on at once then connected sync, done works good now. Cheers!

“Full breakout board compatibility list.”

This needs to be updated as the X15*B* isn’t listed at all on that page.

My expectation (correct me) that it is the same compatibilities as the X15.

Also, I had an ‘in stock’ notification for the X15, so you may want to notify those people that the *B* is the same and available now.

17 days 17 hours ago

We are still checking all PSUs compatible with the X15B. We will revise when we have the data. Thank for the head-up tho.

What is the length of the cables if ordered as a package deal? I don’t see that listed anywhere.

Hi Joseph. I have $500 in Dell 1100w 0YT39Y power supplies showing compatibility with the x15. The new x15 rev :b which we were pushed into purchasing as an upgraded replacement to the orignal x15 is not compatible with the PSUs on x15s compatibility list. I think alot of your customers waiting for the x15 will be very disappointed that these new boards are not compatible with the power supplies listed compatible with the x15. Do I need to ship all of these x15:rev b boards back to parallel miner? It looks like you are aware of the problem that it’s missing one or more solders.

Hi Chris, we posted a quick fix for the 750 & 1100 watts here X15 Fix We understand not everyone have the tools to do such work. If you need to return your current stock we will pay for shipping both ways and send you units with the fix already applied. Please reach out to us using our contact page. Best Regards

Hello, i have a DELL PSU F750E-S0 (S-0750ADU00-101 / 06W2PW) and it’s compatible with X15 card. Is my power supply compatible with the X15 Rev:b card ?
Moreover, i live in France and i must 40$ for shipping. Can you have a cheaper carrier ?

    Well waited 4 months watching parallelminer for the x15 board. Joseph G from Parallelminer in early November said a new version is being developed and will be coming soon plus the quantity available will be in the thousands enough for everyone who have been patient.

    Parallelminer makes pre-sales available and I place my order on 12/14/2021 before the launch on 12/20/20121. My credit card is immediately charged the full amount of the order.

    I see it available on parallelminer for a week and a half. After one week I call in to check my order and Shaun from Parallelminer assures me that my order will be processed and that they will send me a new email once it is. Fast forward a few days after that and I see that my order was not processed and has been cancelled as the product is no longer available….

    Not sure what happened here but this is really poor customer service. I have contacted Parallelminer for further explanation on what happened.

      Chris, we received 100 units and the remaining 900 are currently being held in Customs. We took them off until they are cleared and in our stock. I’m expecting them back in stock any day. We have 2000pcs in production on top of these 900pcs. Shaun was instructed to issue a refund for any customers who requested it.

    Pre-ordered on November 30th, got tracking info on December 23rd, received 5 X15 on December 31st.
    It works perfectly on Dell D2000E-S2 XYK93 which is not listed on REV:B compatible list (compatible with old X15). I will test it on Dell 1600W PSU when I have time.

    • Joseph g (store manager)

      Thank you for the info. I have updated our listing reflecting the D2000E-S2 XYK93.

    It doesn’t really say so, but this is NOT the same board as the x15. It has different compatibility apparently, so do not buy this for any psu listed as x15 compatible.

    Received several X15 units today and everything seemed to be working fine until I found out that the server PSUs I have synced with the ATX PSU turn on by themselves about 20sec after shutting the system off. When I remove the sync cable, I can turn off the server PSUs via the button on the breakout board and as expected they stay off. I’ve tried multiple 1600W and 1850W Dell PSUs and nothing seems to work. I’ve already gone in and disabled any sleep states or self power on in the BIOS and still doesn’t work. In summary, The server PSUs consistently turn back on around 20sec after a windows shutdown or a hard shutdown.

    • Joseph g (store manager)

      We will try to replicate this on our side and share the result here with you in one or two days.

    I had to do the solder fix on my 15b boards.
    However when the 3 lanes are connected as shown in the picture above my 750w dell psu is constantly on and the power button does not work. If just the first 2 lines are soldered it works with the power button.

    • Joseph g (store manager)

      Hi Clayton. Well noted and thank you for the info. We will verify this on our side.

    Didn’t work when I got it. As the comments indicated, I had to solder the last 3 pins for it to work for my Dell 1100W 80+ Platinum PSU (38GYJ). It seems they will be updating the board to fix this. Also, buying this from Canada is crazy expensive.

    I have 2 Server Power Supply 1100W GYH9V, is this breakout board useful for me?
