a 400 Watt PSU for that system though.

How to know if a power supply unit of my computer case would supply enough
power for 3 HDDs, a DVD-ROM and a DVD-RAM drives? I want to add a third HDD.

Apart from the watts available, which should be >300W: one needs to have
lots of power [Amps].

Component Requirement Line(s) Used
AGP Video Card 30 - 50W +3.3V
Average PCI Card 5 - 10W +5V
10/100 NIC 4W +3.3V
SCSI Controller PCI Card 20W +3.3V and +5V
Floppy Drive 5W +5V
CD-ROM 10 - 25W +5V and +12V
DVD-ROM 10 - 25W +5V and +12V
CD-RW 10 - 25W +5V and +12V
7200rpm IDE Hard Drive 5 - 20W +5V and +12V
10,000rpm SCSI Drive 10 - 40W +5V and +12V
Case/CPU Fans 3W (ea.) +12V
Motherboard (w/o CPU or RAM) 25 - 40W +3.3V and +5V
RAM 8W per 128MB +3.3V
Pentium III Processor 38W +5V
Pentium 4 Processor 70W +12V
AMD Athlon Processor 70W +12V
For overall power supply wattage, add the requirement for
each device in your system, then multiply by 1.8. (The
multiplier takes into account that today's systems draw
disproportionally on the +12V output. Furthermore, power
supplies are more efficient and reliable when loaded to
30% - 70% of maximum capacity.)"
*******************************************
My Celeron can use 88 Watts, a P4 could use much more.
A motherboard can use 50 Watts
A video card 50 Watts depending on model
Each hard drive 25 Watts, an optical drive would use 25
Watts to read and maybe 40 Watts while writing.
Each RAM stick uses 10 Watts or so/per 128 MB
You need extra capacity to handle start-up surge loads.

Jim Macklin said:EVEREST will show you power required by the CPU and what
devices are installed. All power supplies have same voltage
standards. If you try to draw more power than rated power,
the voltage will drop to the low end of the range or below.
There is no other method that I know of to plan in advance
