idk the exact values but you can find a chart that has wattage usages of common parts(e.g. dual core 3.0ghz processor, video-card, sound-card) and just add those up, give a little more leeway so as to not be stressing to power all components. also, your components should be labeled at a certain wattage use. good luck!

The motherboard model, cpu model, and graphics card are the major determinants in choosing the correct power supply. Good to have about 20-25% more than you actually need, because you don't want to be running at full power all the time. The amperage amount of the power supply is also important, not just watts. Cheap, generic, and free ones are what to stay away from unless you are building a very basic economy PC.

Well It all depends on what your putting in it. But to be honest figure out your budget, then look for a quality product in that price range. If your not planning on spending at minimum 80 bucks (Retail) for a powersupply your probably looking for premature failure, and we all know that that leads to... dissapointment, thats where. you can normally get away with skimping on things like memory prices and finding a cheaper motherboard with less of the options you will never use anyways, but if your looking to build a decent running machine look for 550 watts or above. Even if you dont need all that power youll just be putting less stress on it in the long run.

Power Supplies: How Much Power Do You Need?
Component Requirement
AGP Video Card 30W – 50W
PCI Express Video 100W – 225W
Average PCI Card 5W – 10W
DVD/CD 20W – 30W
Hard Drive 15W – 30W
Case/CPU Fans 3W (ea.)
Motherboard (w/o CPU or RAM) 50W – 100W
RAM 15W per 1GB
Pentium III Processor 40W
Pentium 4 Processor 80W – 125W
AMD Athlon Processor 80W – 125W
For overall power supply wattage, add the requirement for each device in your system, then multiply by 1.5. (The multiplier takes into account that today’s systems draw disproportionally on the +12V output. Furthermore, power supplies are more efficient and reliable when loaded to 30% - 70% of maximum capacity.)

on how much you are putting into our computer. if you are having a graphics card 400watt is almost always recommended. Then if its sli or crossfire probably about 700-800 watts. then it all depends on what else you put in, if you are having many cd/dvd drives and hard drives and components get a little bit higher up wattage psu.

You should get a 550 watt antec. best choice. or a demon 580 watt and it glows red or u can get one that glows blue and tehy only cost $39.99

Hi. Too much power is just right, IMHO.

my suggestion is no lower than 500w if you want a good performing system
