PWS-1K41P-1R, is it compatible? (Forgot to turn on notifications on other comment)

Unfortunately it is not compatible. The compatibility list is still incomplete, but the most updated breakout board compatibility list can be found here: https://www.parallelminer.com/uncategorized/breakout-board-compatibility-list/

Hi Thomas,

At this time we do not have a breakout board for the PWS-1K41P-1R SuperMicro 1400w power supply. This model uses a slightly wider power slot and the X20 board will not fit. We did however just send over a sample power supply of the PWS-1K41P-1R over to our factory in China to have a new board produced for this model. Please check back with us at a later time for stock! The board will most likely have the model number X21BRK.

Hi, I was wondering did you ever make a revision with model number X21BRK that is compatible with the Supermicro PWS-1K41P-1R power supply?

Also do you sell any breakout board that convert the connection to a 12V motherboard connection for motherboards?

Will this work with the HP model number DPS-750RB A

No but our X6B, X7B, X11 will

I have Supermicro PWS-1K21P-1R v1.4, can the issues be solvable??

4 months 20 days ago

Referring to the compatibility list, there is a compatibility issue with PWS-920P-SQ rev 1.1.
I have several PWS-920P-SQ Rev 1.0 so I bought some X20B board, but they don’t work either. 🙁
Amber status led is lit, 3 digit display is blank, the button does nothing. Is there a solution?

    The breakout boards sold from Parallel Miner are in a class of their own! There are simply NO comparisons whatsoever. Other boards get dangerously hot and eventually begin turning dark brown to black (and one nearly caught on fire). I will ONLY use boards sold by Parallel Miner, as they can power my higher wattage PSU’s with ease. Beware of cheap knockoffs being sold elsewhere – Parallel Miner/Centrix is the ONLY place to get these genuine, quality boards!

    Great customer service and your people are far better than some of your business’ policies. You will get my get my return business because of them. This is the second time in three orders they have come through so treat them right.

    An excellent, low price, the part works perfectly, and the shipping was fast. Not much else to say. I’m a happy customer and I’ll be shopping here again.

    This is the 2nd time I’ve ordered the micro breakout board. I’m very pleased with it and also very pleased with Parallel Mining. The board connections are a little tight in certain spots, but it meets the need.
