Welcome to Geeks to Go
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%. 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:
1. Current (amperage or amps) on the +12V rail,
3. Total wattage.
Then look for power supply brands listed under the "Good" column of PC Mechanic's PSU
Reference List. Ensure the supplied amperage on the +12V rails of your chosen PSU meets the requirements of your video card. Don't try to save a few dollars by getting a cheap supply. Digital electronics, including CPUs, RAM, and today's advanced graphics cards, need clean, stable power. A good, well chosen supply will provide years of service and upgrade wiggle room. I strongly recommend you pick a supply with an efficiency rating equal to, or greater than 80%. Look for the 80 Plus - EnergyStar Compliant label
. And don't forget to budget for a good UPS with AVR (automatic voltage regulation).

If you haven't purchased these items you specified, I would reconsider purchasing the ECS MOBO.
It is one of the low-end manufacturers. There are usually problems with their hardware to some extent...
You could\should consider a MOBO by:
Also you are looking at 800mhz ram when you could be looking at 1066mhz ram
This will help speed up your computer...(Of course only if all the hardware supports it)
Hopefully this helps and answers your questions...
