[NSRCA-discussion] Curmudgeon's Rant

[Del K. Rykert]

Many computer power supplies are switching power supplies and don't deliver 
the full rate except at power up then switch to a lower full time use 
rating. You can buy full duty cycle power supplies for computers but their 
cost is often double of the cheaper (typical) computer power supplies.
