PSU & RAM Questions

Specs: Windows XP, XP 3000+
I'm building a new pc around this motherboard:

Which memory speed should I be looking for?

DDR3 1333 (PC 3 10600)
DDR3 1333 (PC 3 10660)
DDR3 1333 (PC 3 10666)

The three listed above all have different module names. Which one should I be looking to buy, or does it matter?

CPU: AMD Phenom II X2 550 Black
AMD Phenom II X3 720 Black

Video: Been leaning towards the Geforce GTS 250 512 MB.

PSU: Judging by the above specs, what kind of power requirements should I be looking at? I would like to have a high amperage single rail unit. My question is: what is the minimum amperage on the 12V rail I should be looking for (30 amps?) and what total wattage should I also be looking at? I only have one optical drive and I will be using one hard drive. However, I will have 2 HD's hooked up temporarily for transferring files.

They are all the same speed. The numbers are rounded off by some.

Look for Dual channel RAM the runs at 1.5V for best results. Check out the link below.

Read the first review at your link. You may need to know that information.

I tried to link to the Asustek site for the QVL for RAM but it appears to be down. Although it isn't absolutely necessary to do it is best to choose RAM that the vendor has already tested on the board.

I am curious as to why you chose that 790 board.

Processor = 125W for Phenom x3 145W for X4
Card = 127W each some cards draw 205W each
RAM, drives, board, etc.?

So, it depends on weather or not you ever install a second or faster pair.

If you want to cover most of the bases you should go for a single rail with about 50A @+12V.

If you can make any good motherboard recommendations, please let me know. I don't want to spend more than $120. I'm still shopping around, haven't committed to anything yet. Thanks

Do you ever intend to run 2 graphics cards?

How many SATA ports do you need?

Any interest in integrated graphics if it is free?

Not two graphics cards at the moment. I can't say I wouldn't want to run 2 in the future, just not anytime soon.

I don't need a ton of sata ports. I generally run only 1 or 2 hard drives, along with at most, 2 optical drives. 4 total. Most modern motherboards come with a whole bunch anyway, right?

Well, I've considered integrated graphics. I know some of the new amd/ati offerings are not bad performers. My dad built a phenom II X4 system earlier this year based on the 790GX northbridge. I'm pretty sure it has an ati 3300 igp.
Older games ran pretty well, however, newer titles not so much. He eventually upgraded to a 4850 512MB. I still want an actual video card solution though, especially for today's games, which I cannot play currently because of my dated hardware.

I've seen some of the new boards sporting the ATI 4200 IGP.
As you can see from the link below, that particular solution ranks pretty low on the hierarchy chart.

BTW, what is so bad about the 790X anyway?

Nothing bad about it. Just wondered why you chose the board you did. I will check out other possibilities later today.
