Question about PSU

Hey guys
My system configuration is as follows
core 2 duo E4500 @ 2.20 GHz
Asus P5GC-MX motherboard
Zotac GeForce 9400GT graphics card 1GB GDDR2
1 GB DDR2 Ram
160 GB HDD

I just wanted to ask that if I upgrade my system to 2 GB Ram and add another 160 GB HDD will my PSU with 450W rating will be able to handle these components?
Thanks in advance.

Which company PSU is it?

If the system is running fine now, there is a very low probability of an HDD causing it to go kaput. I would worry when there are more than 2 HDD's though.

No problem with that..I used to have 2 HDD - 160GB and 250 GB, 4850 GPU and 2 GB Ram and I never have a problem..Although get a real power PSU from known brands..

Well I don't think so adding a HDD or 2 will cause any problem with this configration....have your overclocked your CPU???

How much power an HDD consume?

this should solve your problem: *www.msicomputer.com/index.php?func=power

the output wattage in your system should be always less generally,as thats the maximum possible value calculated (in the site above).

How much power an HDD consume?

the modern drives use 15-25 watts at max.

Should not be a problem, though you should post the brand and model no. of your PSU.
