PSU efficiency for typical loads seems to be around 70%-75% (give or take a few percent depending on the quality of the PSU). Its just a matter of time before all power supplies have some sort of load monitoring method, just like most all motherboards now have software for monitoring fan speeds, temperature, voltage from the PS. Has anybody seen a smart power supply that can indicate load? That would be a bad move on the part of the PSU manufacturers: It would cost them money to include this feature, and it would convince their customers to get smaller (cheaper) PSUs next time. Followups set to colh, because I read that. Right, and to hell with everyone else, who doesn't. Stupid troll. - anton |

Sure, but it certainly gives an upper limit for the output of the PSU. So since my PSU never draws more than 180W on my Athlon 64 box, I know that my 365W power supply is overdimensioned. In that particular situation you know that anyway from a calculation. Of course one also has to take the load for the different voltages into consideration, not just the overall rating, and the input wattage does not help that much there. Which is what I originally said. PSU efficiency for typical loads seems to be around 70%-75% (give or take a few percent depending on the quality of the PSU). Utterly mangled all over again. Its just a matter of time before all power supplies have some sort of load monitoring method, just like most all motherboards now have software for monitoring fan speeds, temperature, voltage from the PS. Has anybody seen a smart power supply that can indicate load? That would be a bad move on the part of the PSU manufacturers: Wrong. Some would buy a supply like that. It would cost them money to include this feature, and it would convince their customers to get smaller (cheaper) PSUs next time. You dont know that either. Followups set to colh, because I read that. **** that. You have always been, and always will be, completely and utterly irrelevant. |
