How safe would it be if I potentially overloaded the +5 rail? This is assuming that I would have a good quality PS like a Fortron or Sparkle and my theoretical +5V max power draw was ~10A past the PSU's max rating.
I'm planning on replacing the PSU on an older Athlon XP system with modest power consumption, so I'm looking at relatively inexpensive 300-350W power supplies. The problem is that the motherboard doesn't have the 4-pin power connector. If I understand correctly, the CPU in this configuration will draw power from the +5 rail. This along with my Radeon 9500 Pro will probably draw a lot of power from +5.
A lot of 300-350W power supplies, particularly the Fortrons/Sparkles that I am leaning toward, have a max of 30A on +5. I figure that my theoretical +5 max would be around 10A over that.
Should I worry about this potential overload? After all, if I'm playing a game I would expect to have full utilization of the CPU, videocard, and memory. Or perhaps I am just thinking about this too hard?
Note that I'm making a lot of estimates based on takaman's calculator. Since the 9500 Pro wasn't listed I'm assuming that it's similar to the 9700 Pro but with somewhat lower power consumption.
