NEED LOTS OF POWER!!!
If your PSU's no good, it can cause
amazingly diverse problems. Underpowered or otherwise
defective PSUs don't necessarily have the decency to
just go pop and stop working, you see. They may
do that - or they may decide to go out in company, and
pass mains voltage through to the motherboard. But
they're more likely to just suffer voltage sag.
Voltage sag is your own little private
brownout inside your computer case.
Different computer components have
different tolerances for low input voltage and other
supply oddities, and will foul up in different ways when
underpowered. Most of these ways are unlikely to give
you any obvious indication that it's the PSU at fault.
If you don't know the PC service-person's mantra -
"if the problem's bizarre, try another PSU" -
you can waste days swapping boards and changing drivers
and fooling with your RAM configuration, and still
have a computer that flakes out whenever, for instance,
all of the drives are accessed at once.
So that's one reason to buy a more
expensive, beefier PSU.
