View Full Version : Will low wattage powersupply cause device to fail?
Josh Collins
December 5th 03, 12:42 PM
I bought the cheapest powersupply I could find when I had my computer
assembled but I know nothing about the powersupply and there are no manuals.
Since then, I have added another hard drive (so now I have two) and a CD
Writer. The processor is a PIV 2.GHz. I have a printer and scanner connected
as well, but I don't use all of them at the same time. Still I am wondering
if too many devices--especially two hard drives--connected to a low-powered
power supply will cause one of the devices to fail. I am particularly
concerned about the two hard drives.

Josh,
Yes,
If your 2 drives plus CD are drawing too much such as during the start of a
big copy from CD or hard disk to hard disk, you may experience unpredictable
system performance or failures.
Just what output is your power supply?

Hi,
Yes using a low powered powersupply can corrupt your
system. go for a Uninterrupted Power Supply (UPS) which
maintains normal voltage supply for the system and you
wont have to worry about the hard disks in future.

FWIW M. Rajeshs' reply makes no sense at all. The capacity of your power
supply is unaffected by the source of the power. I.e... if you have a 250
watt power supply it is still capable of sustaining a 250 watt draw whether
the power is coming from the wall (mains) or from an uninterruptible power
supply.
That said you can find a chart of the typical power draw for different
computer periphery here. http://www.aapspower.com/abpowsup.html add up what
you have in your system, add a little for tolerance and if you find your
total component draw is approaching the capacity of your current power
supply get a higher capacity PSU.

Rubbish.
How on earth is a UPS going to help an under-rated power-supply?
It's only purpose is to smooth out mains fluctuations/spikes & maintain
power for a limited period during outages.
The simplest solution is to read the rating label of the installed PS, go to
a knowledgeable & helpful PC constructor, tell him what the system &
peripherals are and heed his advice.

Well said! Added to that, a dime-a-dozen PSU is usually only capable of half
its stated output (e.g. a 400W is really only stable up to 200W). The power
supply is the one thing you DON'T skimp on when you're building a system. A
cheap PSU can damage half the components in the system when it fails (as I
know to my cost). A proper branded PSU (Antec or Enermax for example) will
fail 'gracefully', and the rest of the system will remain unhurt. A £10 PSU
could end up costing you £200 in replacement parts - it's a classic example
of false economy.

What hogwash. Would you care to explain that. If the OP could tell us the
wattage rating of the power supply perhaps we can make a judgement call.
