I'm going along with this setup and have spent about twice as much time finding a suitable case and PSU than I did for the whole rest of the machine which is as follows:

Athlon 64 3000+ MSI K8N SLI Platinum
Mushkin Dual Pack 184-Pin 1GB(512MBx2) DDR PC-3200
eVGA GeForce 6600GT PCI-Express
1 CD-RW
1 200gig Maxtor ATA
Now for my PSU I I think I've settled on this:

I don't really know where to look for how many 'pin' my motherboard and my PSU is. I've heard mention of 20 pin and 24 pin and am hoping this will work.
I've tried to do as much research as possible readings various guides and FAQs throughout the internet but I still would like to hear some expert commentary on what I've picked out and if this isn't going to work maybe a few suggestions or a point in the right direction.

Thanks for your time,
clint

for this MB you need atx 12v 2.03
i would reccomend the fortron it is one of the cheapest at 80$
some atx 2.03 psu`s can cost up to 180$
to find out more about your MB and its requirements go to msi`s website. If you get a psu under say 400w you might not be able to use sli in the future so it is worth spending a little extra now

Alright, I think I have something picked out but I don't know how to find out how many pin connector it comes with? I just don't want to get everything there to find out that my power supply doesn't hook up to my motherboard.

It looks like the 12v rail is going to be sufficient for now with what I've listed and upon further research I did discover that it is ATX 2.03. I'm still however stuck with wondering if I'm going to be able to connect this sucker to my board.

thanks

if it is atx 12v 2.03 then it should have a 24 pin connector. if it does not have a 24 pin connector you can get a 20 to 24 pin connector. you seem pretty strong on doing what you want anyway, you will be wasting money. When you upgrade to sli you will need a more powerful psu. And if your not going to use sli then get a single pci-e MB you can then use a less powerful psu. Is this your first build?
If your unaware of how many pins something has or the specs the best thing to do is visit the website of the manufacturerif that doesn`t help do a web search of the item hopefully someone did a review of the item if they did they might tell you specifics if not, alot of times they post pics and you can actually count the pins or see the connectors it has.

please do not underestimate how important a psu is. I did this on my first build. It can lead to a lot of problems your better off putting the pc in a cardboard box and using a good psu, instead of getting a good case and using a crap psu.

You don't need an ATX 2.03 power supply to get 24-pins. EPS12v power supplies have had them for many years, <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?descripti..." target="_new">Here's one</A>

As for doing what I want I've had 4 other opinions on the matter. You have to understand that I'm on a very limited budget and originally I was looking for a case and supply for around 70 bucks. I have given up on this and decided to go with something like I posted in the previous message. I apologize if it sounds like I'm not heeding your advice but unfortunately I'm bound by my wallet. What I was talking about earlier was that case and PSU which had 21a on the 12v rail for around 70 bucks. I realize that this probably wouldn't hold up when coupled with another SLI capable card or possibly a simple upgrade to the 6800. I thought that the supply that they provided (Antec SL350S) would be sufficient for the time being. I will be running 1 hard drive, 1 CD-RW, 1 processor, 1 PCI-e 6600GT, 2x512 mem, all on a MSI K8N SLI Plat. It kinda seems that no one is really sure on how much power the PCI-e cards are drawing especially in SLI and would be best of course, to err on the side of too much rather than too little. I would love to do this but I'm on a budget soo. At this point I'm just on the lookout for a PSU that's around 80 dollars that has the 24 pin connector (ATX 2.0x) and would handle some upgrading in the future. Is it possible?

Again, I'm sorry if I don't seem to be considering the advice given it's just hard for me to communicate effectively in a way such as this. I GREATLY appreciate all the advice. I do.

Thanks again,
clint

Yes, I'm certain it's possible. For example, the Fortron Source 500W Blue Storm is $90 at Newegg, but I'm sure you could find similar quality for a bit less expense.

i think you will be ok with a 350w + antec, as long as you use the set-up you are currently suggesting. But what i`m trying to tell you is if you think of upgrading down the road you WILL have to upgradede the psu as well. then the money you spent now will be wasted. As far as the motherboard pin layout there are converters for that ie. 20 to 24 pin - 24 pin to 20 pin. and ect. If its going to help you save money and you`ll be ok sending more money later on get the antec with case, that one was like 70$ but keep in mind if you upgrade to even a 6800 you might need a new psu. you will know because your system will become unstable. The 6800 has a pci-e power connector the 6600 gt only uses mb power. the 6800 uses almost 75 watts from the pci-e .

ps when you respond to a particular message click on THAT messages responder located in that top right hand corner
otherwise that person will never receive an e-mail and then they will never respond back.

good luck

crashman i could be wrong but the eps 12v psu`s are pretty expensive and come with connectors most people don`t need. i don`t think clint would benefit from one of these.

I think I've actually seen the Fortron Source EPS power supply going for $10 LESS than their ATX 2.0 power supply of similar rating.

yeah i think your right
but still it includes a connector or two most people are not going to use. i guess he could just tie them up. In any case i think he would do ok with that antec he mentioned for now.
