80+ Platinum 94% Certification:

With the increased popularity of ASIC and GPU mining many overseas and domestic sellers are taking advantage of the lack of knowledge of some users. We have seen an increase of sellers passing these HP 1200W PSUs as 94% Platinum rated. The only HP platinum 1200W PSU in the market are the ones with the following part numbers:  570451-101, 643956-101, 643956-201, 748283-201. If you bought a HP 1200W PSU and it does not have these part numbers, IT IS NOT 94% PLATINUM CERTIFIED.

Does it work with the new Avalon A741? I’m ordered one yesterday from u guys… just for testing 😉

Yes it does … Always better you plug the PSU in 200v+ AC but will also work on 120V – WILL NOT ON 110V

    • Joseph g (store manager)

      We do not include power cable because they are to many variant.. Will it be to the wall or PDU? 120v or 220v ? will it be in the USA , UK, HK, China or Germany ? | So power cords are never included

    does it work well with AVALON 741? someone told me that I may need to lower VOltage to run well? any thoughts? would you recommend this for avalon 741?

    • Joseph g (store manager)

      Its best when plug into 200vAC but will still be ok at 120AC. IF you have 110vAC I do not recommend
