For you "DIY", before you begin to build your new dream machine always consider first and foremost how much power will you need.
Your Power Supply Unit is often overlooked. But its critical in your build.
With Windows 7 and the newer dual/quad 64 bit machines the standard 300-350 watt PSU's are no longer able to handle the greater power demands placed on them.
The posted link will start you on your planning for your custom build.
I'm not espousing ASSUS products but the site is a very good tool.

BUT - like all of these calculators, they don't really provide for overhead (so the PSU is not maxed out all the time), future hardware additions, user's computing habits, or aging of the electronics. So, using my canned text, I recommend the following to ensure your next PSU purchase will carry you through YEARS of service and upgrades:
Use the eXtreme PSU Calculator Lite to determine your power supply unit (PSU) requirements. Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom of the page. I recommend setting Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home), I recommend setting TDP to 100%. These steps ensure the supply has adequate head room for stress free operation and future demands. Research your video card and pay particular attention to the power supply requirements for your card listed on your video card maker's website. If not listed, check a comparable card (same graphics engine and RAM) from a different maker. The key specifications, in order of importance are:
