NOTE - PLEASE READ: Please double check compatibility. This kit is only compatible with 12V Whatsminers (see third photo for example). If your sticker indicates you have a 14V variant, please check back at a later date for availability.
Everything you need to add an additional 1900-2500w of overclocking overhead to your whatsminer!
This secondary PSU powers the third hashboard independently, allowing the stock PSU to power only hashboards 1 & 2. P21D power supplies can supply 4100w, allowing for 6150w total. All other P21 variants have a 4000w max (recommended to run at 3800w on air cooling), allowing for 5700w sustained load. The secondary PSU comes on and off automatically based on the state of the main PSU.
Use in correlation with Manifold Mining custom firmware to obtain 40+% hashrate increase over stock configuration.
