What would the power requirements of the following configuration be?

Question

The following is the configuration of my PC. I would like to know if there are any sites that would calculate how much power these components would need or if anyone with similar configurations could help me out. Right now I have a 400W PSU that i was using for my previous system. Will that be enough??? Or will I need to change it???

Intel Core 2 Duo E8400 [3.0GHz]

Intel DG33FB Motherboard

2GB DDR2 Ram [800FSB]

XFX GeForce 9800GTX 512MB Graphics Card

80 GB Hard Disk [IDE Interface]

Sony DVDRW

Answer 1

With a rig like that you will need at least 500 Watts.Go to the link and fill out the form-but don't forget anything.When he tells you what PSU power you need ADD 15% for safety.You might want to upgrade later.

Answer 2

I would go to www.antec.com. They have a power calculator to help you gauge the power demands. Hope that helps.  

Answer 3

Not enough PSU. They want a 450watt minimum PSU for the 9800GTX. Another thing to consider is the +12V rail amps. I once replaced a Thermaltake 430watt PSU with an Antec 430watt PSU when I put a video card in a customers rig. Thermaltake only had 18 amps, not enough yet the Antec had 26 amps--more than enough.

I like to play it safe and put something bigger in than what is recommended. I recommend this PSU--550watts with one massive 41amp +12V rail so you dont have to monkey with splitting rails. Very stable rails and has all the power you need for further upgrades. Good price at 65 delivered too:

You can tell by the reviews that people love it.

Answer 4

At a guess i would say that 400W is just around or just below the absolute minimum for the setup, although seeing as you only have one optical drive and one HDD will probably suffice, 500/550+ would probably be recommended, try googling 'power supply calculator' as there are a number of these around that can tell you roughly by entering the details of the parts you are using.
