I am building a new computer and was wondering if there is a " wattage formula " for choosing how much power to choose to run a computer ?

Good answers above...and the PSU wattage (and amperage)
by VAPCMD / May 4, 2009 11:56 AM PDT

depends on how much of what stuff you put in the system....esp the CPU and the graphics card. Pegardless of the PSU will only use what power it needs to efficiently run the PC. Efficiency counts too...keep that in mind as you evaluate the PSU options.

Although your participation is appreciated, it's against forum policies to advertise here. Leave out the signature tagline advert and repost your suggestion.

Hope this helps.

Use a calculator

If you plan on running dual/quad graphics cards using SLI or Cross fire then you will need a compatible Power supply.

Also calculate in possible future hardware upgrades.

Check the connections and make sure there are enough and the right type for your mother board and graphics card.

Generally for average PCs 550 watts will do. For advanced gaming PCs, 1000 watts. If your not sure which PC type you have or will have, choose 700 watts.

Side note: Save the plant don't create CO2 by wasting power.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
