I am building up a new system, utilizing an ASUS A7V8X motherboard. This is the full blown version, with all the features available (ASUS p/n 90-M7A610-W0UAY, described on the box as A7V8X/GBL/1394/SATA/R133-UAY).
An Athlon XP2100+ processor is installed, with a Dynatron heat sink/fan combination for cooling. The board has 512MB of Samsung DDR memeory installed.
I am planning to also install an MSI G4Ti4200 (64MB) graphics card, a Western Digital WD400JB hard drive, an AOpen CDRW4850 CD writer and an AOpen CD956E CD reader. The remaining devices are the usual case fans, keyboard, mouse, 3.5" floppy, et cetera.
I have a copy of a technical paper authored by ASUS (document # 26003A, dated May 2002), which provides an excellent procedure for calculating system power consumption. Following this procedure, in order to properly select a power supply it is necessary to be familiar with the voltage/current requirements of each of the components in the system, per each of the available voltage rails (i.e., +3.3V, +5V, +12V, -12V, and +5VSB).
So far, I have determined, with reasonable assurance, the voltage/current values for most of the components in my system. Unfortunately, I have not been able to nail down this data for the A7V8X motherboard (or the CD956E CD reader, for that matter). The manual for the motherboard indicates the +12V rail should be able to provide a minimum of 8 Amperes, but this may be so as to ensure the Athlon processor has sufficient current. I say this because in checking several AMD websites and data sources, it appears the XP2100+ processor requires 7.49 Amperes on the +12V rail. The manual also says the +5VSB should be able to provide a minimum of 1 Ampere. This leaves me with no knowledge of the actual motherboard requirement for +3.3V, +5V, +12V, and -12V rails (assuming the +5VSB really needs a full 1 Ampere).
I noticed this website seems to have excellent technical reviews and articles concerning a great many hardware issues. In fact, I believe this is the ONLY website that actually has a review that explores the claims and capabilities (or lack thereof) of currently available PC power supplies.
So, I have come here in search of the data I need. Perhaps someone on the forum knows the answers, or can at least vector me to a location wherein I can obtain the data on my own. I have already requested this data from the vendors, and am still waiting (2 days, now).
Thanx in advance to anyone who can provide assistance with this problem.
