So I've put together this Gaming computer from scratch using reviews and such on Newegg.com.
These are the parts that I'm planning on going with and have no idea how many watts they consume or need. The power supply is the only thing that has me stumped. I've used several different calculators and all range from 650w - 1050w. (If you happen to have any suggestions I would be happy to hear them. I don't know a ton about PC gaming builds.
Motherboard: (Is this MOBO too big?)
ASUS Crosshair V Formula-Z AM3+ AMD 990FX + SB950 SATA 6Gb/s USB 3.0 ATX AMD Gaming Motherboard with 3-Way SLI/CrossFireX Support and UEFI BIOS
Dude, get at least 1000 watts. I have two 270x, and the xfx 750 watt PSU burnt up with my CFX setup. I also have the 8350. Don't buy one only to buy another like I did. Do it right the first time. Also, at 750/800 watt, your PSU will be working full time all the time. I upgraded to the 1300 EVGA supernova and now the PSU barely get warm.
PSU requirements are almost entirely determined by the graphics configuration. This handy chart suggests 850w: http://www.realhardtechx.com/index_archivos/Page362.htm
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
I have a few suggestions:
Velociraptor was good in it's time, but not today.
Use a SSD instead. a 240gb Samsung evo would be good. Use a conventional hard drive for expansion or storage later if you need to.
I don't think I'll ever over clock. If I need to I'm sure I could just swap out the power supply. So 850w. Thx for the help. However. I still don't know if the full tower is really needed. should I get a mid tower and hope everything fits? one review I read said that this MOBO tends to be big.
