Hi.I'm going to build a rig next year for personal use.I'd like to ask for your opinion on what wattage is needed for my computer.

This is the build.

http://pcpartpicker.com/p/3VKRMp If you'd like me to list it out instead,here are the specs.

AMD FX-8350 NZXT Kraken X61 MSI 970 GAMING MSI Twin Frozr V GTX 970 GAMING 4G Kingston HyperX Fury DDR3 16GB 1866MHz CAS 10 Intel 730 Series 240GB Phanteks Enthoo Pro Cooler Master V850

Id look into getting another 4gig stick of RAM to total 8gb. A 600 watt is good, but push for a semi mod-fully mod gold or higher rated unit.

I already gave it 8GB.... I've found the perfect PSU:DDDD Seasonic Platinum 650W.Fully modular and 80+ Platinum.Sweeeet. Thanks for your comment anyway.Have a good day.:)

This site will tell you what your approximate power consuption will be based on the parts you pick. Use that figure, and get a PSU about 2X that value. If you use 400W, get an 800W PSU. This allows the PSUY to run at a 50% duty cycle, which is close to the sweet spot for efficiency ratings. This holds especially true if you're looking for an 80-rated PSU.

Huh.That sounds like it makes sense.Where did you get it from?

I'm in the US. I ordered mine from MicroCenter online. (I used to work for MC about twenty years ago.)

Also, Coolmax has a MIB on their supplies right now. I got $20 or $30 off on mine. I forget which.. I just sent in a bunch of MIBs from various parts I ordered for this box I just put together.

But the most efficient area is generally 60-80% if I'm not mistaken and the wattage listed is significantly higher than what you are going to be using 99% of the time. Although you should also adjust for capacitor aging, likely upgrades and such. So some between 50% to 100% extra would be best (more if you have major upgrades, like SLI + OCing).

You should always make sure that the PSU you chose has enough amps on a 12 volt rail for the GPU you plan to pair it with.

Alright,thanks.Should I add a few watts more if I want to overclock?
