Hhm, that means a Athlon 2000+, 2200+ or 2600+/2700+ require also high 5V rail... ?!
Well, the high end 3200+ (76W TDP) has 26% higher TDP compared to a 2000+ (T-Bred, 60W-TDP) and 55% higher TDP compared to a 1600+/1700+ (T-Bred, 49W-TDP).
I have one AhlonXP (Thoroughbred B), which i'll clock from 1600+ to 2700+. I Think, a modern PSU with only 15A on 5V rail would be too bad. The question for me would be: How fast and consuming power, must be a CPU that for example a modern PSU with 15A is at it's limit for all components...
