Amount of Wattage

Venator44 · Dec 23, 2013

I'm looking for a good power supply for a computer that I might build. I don't want too little power, so I searched around for some websites. http://www.thermaltake.outervision.com/ gave me a recommendation of 362 W. I somehow think that this is not enough, and I might be filling in different/wrong information.
My components are:
- AMD FX 6300
- ASUS M5A97 EVO R2.0
- G.Skill 8GB PC3-17000 (2 x 4 GB)
- MSI GeForce GTX 760 - 2GB - PCI-E
- Western Digital Blue, 1 TB HDD
- Kingston Technology SSDNow S200 30GB
- LG DVDRW SATA 24x , lightscribe bulk, black
- Gigabyte Sumo Alpha

If somebody could help me out a bit, or give a general direction to look at, I would really appreciate that.
Thanks in advance!

That is actually about right for the bare minimum. But it's best to have some margin for error, so at least 450W is what I would recommend, and preferably 500-550W. There aren't many quality PSUs below 400-450W anyway.

here is a chart showing recommeded wattage based on type and amount of GP(s) being used:

there is also a power calculator app/program on the page. I'd recommend getting a quality PSU from a manufacturer such as Seasonic, XFX, Corsair (except their CX series) or Antec.

360W sounds about right for the absolute worst-case power draw from these components but under real-world use, you will probably rarely hit 300W. In principle, a 400W PSU should be more than enough but due to component aging, build quality and other factors, larger margins are usually desirable and that's why people usually shy away from pushing average (but still good) PSUs higher than about 60-70% of their rating. So for your system, a mid-range PSU in the 500-550W range would be best... or ~450W if you shoot for higher-quality units.

Id get a 650 watt PSU, so you'd have room and if you ever thought of upgrading further, remember get a good quality PSU such as http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=8521720&SRCCODE=WEBGOOPA&cm_mmc_o=mH4CjC7BBTkwCjCV1-CjCE&gclid=CPT7wPW_x7sCFWRk7AodYi8AUw!

floppysnappy :

that's a "refurbished" PSU you linked, wouldn't touch it with a 10 foot pole, but that's just me.
