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.

    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!
