I have to say I know nothing about the Ultra psu's other than . . well . . that I know nothing about them.
My advice - look for a known good quality power supply such as Corsair or Seasonic.
This Seasonic S12D850 from NCIX.com is a steal at CA $110.00. available at that price until close of business Tuesday the 6th. Add to that, free shipping (ground) or overnight for 10 bucks, makes that very hard to pass up.
