[Replying to both responses to my previous post - thanks, guys!] I know all of that, but I was not at all concerned about the power (or current - they are effectively equivalent if your 12V is there) drawn by the new card. The box is not overloaded by HW, and the card is not particularly demanding (well, I could get a higher end model, but I didn't even consider that, primarily due to power considerations). All I wanted to do was to get a rough idea of the total power requirements of my pure vanilla components (MoBo + CPU + RAM + HD + fans + DVD/RW + USB + the new card) and make sure that my PSU - also pure vanilla and acquired without any special thoughts - would not be overwhelmed. This is what is done by those power calculators, and I do think they have a safety margin built it - if your configuration draws 398W they won't show 400W as sufficient. I was not building a high end "gamer's" box with super-overclocked graphics, a monster NIC, 5 HD's, 8 fans, and 128GB of RAM, which is where finer considerations like those you mentioned come into play. FWIW, the card is in and is working fine so far [that's half a day uptime already :-)]. It's max power is 65W, not 165W. ;-) I could (and did, in the end) power the box down and look inside, but I didn't want to, for some good but uninteresting reasons, and because I was loath to do it before exhausting "software" options. And, of course, I was curious - always a good excuse for me. Thanks again, and sorry for making you think I had less trivial needs, -- Oleg Goldshmidt | [email protected] _______________________________________________ Linux-il mailing list [email protected] http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
