To be able to achieve the small horizontal emittance of the ALS-U, the three bend achromats in the ALS will be replaced with nine bend achromats. Because the lifetime of the ALS-U beam will be significantly reduced, the plan is to use a swap out injection scheme between the storage ring and a new accumulator ring. The present plan is to use individual power supplies for each magnet in the storage ring, and series connected magnet strings for the accumulator ring. The sheer number of supplies needed, along with the tighter stability requirements for the ALS-U, is demanding in terms of the power supply requirements for stability and reliability. This paper will discuss the ALS-U magnet power supply requirements, and possible options to meet them.
