Question by Badtzmaru: how much watt do i need for my power supply?
im planning on building my new gaming computer…
questions
how do i find out how many watts do i need?
for the basic gaming computer around how many watts is needed…
imma just compare the two…
XD im thinking of going with a 500 – 650 watt..
Best answer:
Answer by PChardwareExpert
at the LEAST 450 and at the most 650
Give your answer to this question below!
Most computers use anywhere from 250 to 350 watts. You don’t ever want to run a power supply at the maximum watts, so to get really stable power, you go higher. This will also increase the life of the power supply.
If you’re getting a power supply, I prefer the 650. That way if you decide later on to go SLI, or add another couple of drives, the option is there for you to do so.

You should do a back-of-the-envelope estimate of power consumption for your build. The two main power using components are the graphics card and CPU (usually in that order). What we’re interested in is the worst case power requirements. For example, an AMD Phenom II X4 810 uses up to 170W according to this Guru of 3D article: http://www.guru3d.com/article/amd-phenom-ii-x4-810-and-x3-720be-review-am3/4 That includes the motherboard, a hard drive, RAM and an integrated graphics card. The Nvidia GTX 260 (1GB) uses up to 191W according to this Tom’s Hardware article: http://www.tomshardware.com/reviews/geforce-radeon-power,2122-6.html The next page also gets into power requirements. Those two alone total up to 361W. Finding the exact power requirements any extra components like a DVD-RW burner, additional memory, additional hard drives and fans is somewhat trickier as the values aren’t always published. “Safe” numbers I’ve seen are 50-75W for the motherboard, 15W per disk drive, 20W per DVD-RW drive and 15W per RAM DIMM. Add 4-7W per fan depending on the size. Combine that with what you had before. Assuming we want no more than a 50-70%, divide the total by .5 to .7. So, if you came up with 390W as a total, you want a power supply in the 557W (70% load) to 780W (50% load) range.
