I have had PS fail in the past, none took out any equipment with them.
Had a few Logisys supplies from back when CompGeeks used to sell them. They worked ok so long as you didn't run them at max ratings. Speaking of Geeks I wonder who made their private label Cool Power brand, those supplies were way over rated.
Very hard to find anything new that does over 20A on the 5V rails these days, higher rated designs are just for 12V video cards. That's why I keep the old supplies around for older systems. I kept the old Thermaltake 550W supply from my Xaser III case when I stuck a modern Corsair 750W supply in it. The old supply was built for 5V designs (will use it with a dual Athlon MP board someday).
