What I think is worth noting here - a somewhat highend system like this still uses barely 250W at _full_ load.
Still, I don't know if those new measurement gadgets can be trusted. I mean I don't know, not that they are bad.
I don't know if they can be trusted, but I can't really think of a reason not to. I guess I could find a well-defined load (a large wattage resistor for instance) to check it.
The important thing is the power needed at each of the internal DC lines. Some one said that the MB nowdays uses power from the 12 V line, and also the video card uses it (I don't know what for). Plus the fans, the high speed drives... sum all of that. If it close to 10 Amps, and the 350W unit can supply only 10 A (for instance), then you really need a higher wattage power supply: not because you need that so much power, but because one of the lines uses much more power.
Or a powersupply with a higher output rating for the 12V line. But you're right, point taken.
Ie, the peak power during spin up is 2.8 Amps on the 12V line, 0.8A avg maximum during seeks. The power supply must be able to handle that, and if it is true the MB uses also that line, there will be problems.
Well, although the measurement device cannot measure peaks, the harddisk spin-up time is 3-4-5 seconds or so, so I think I would have seen any excess load. During startup, the machine used up to 175W. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
