I'm thinking about building a new computer.  I have an old case with a 200w power supply in it.  Would this be enough to power all the components for the comp. or should i get a more powerfull power supply.  I plan to have one hard drive, 1 cd writer and a floppy drive.  I know power supplies aren't expensive i just want to know if the 200w will be enough.
    Thank you

Hi rivaldi,

Depends on the other hardware, but generally speaking, everything under 350Watt is underpowered for recent hardware.

Greetings,

Since underpowering a system can damage components in the long run, as well as fail when you need it most, I would advise against skimping in this area.  Most low output power supplies are cheaply made and have poor voltage regulation, so it may cost you the price of a motherboard, in addition to a new power supply when it goes.  I recommend an Enermax or Antec to build your system with.  I use an Enermax 365 and it has held up over the years.

Not only do you want a new powersupply for the reason LucF recommended, the newer ones also have short-circuit protection and other benefits, so even if there is a power problem (surge, etc) it will kill the PSU and not the entire system.

The 30-40 bucks or so you'll spend on the new PSU will be well worth the investment.  And don't buy generic, get a decent brand name.
