300w Power supply size for p4p800 can i ass a 2nd HD ?

(Raptor 10k rpm SATA) or is it to much for such a small PSU ? Thank you ! Arthur Try this power estimator: http://takaman.jp/D/?english The power supply rating printed on the label on the side of the power supply, is what you want to compare. Look at the rated current for +3.3, +5.0, +12V, and see if the Macron has more current to offer, than the values you get from the "takaman" calculator. The power estimators I have examined on the Internet, are uniformly pessimistic. For example, when I ran the numbers for your system, I got close to 300W from the "takaman" calculator. And, that estimate is higher than it should be. The measured power for my 2.8C P4C800-E with a 9800pro video card, is about 150W. Another disk drive would add maybe another 12W to that, for a total of 162W. In the end, it is your personal judgement that counts. If the Macron is making funny noises, gets extremely hot while operating, or the measured voltages change a lot when the CPU is very busy, those are also indications that a better power supply should be purchased. If a power supply fails, it can do some very expensive damage. Paul |

Thank you !
i'll try to keep the actual psu with the second hard drive as it looks marginal but "okay" Thanks again ! Arthur "Paul" a écrit dans le message de news: ...
