Im almost done putting together my build, and just realized something.. My Cooler Master Case includes their 430w power supply, and in reading the specs, its got no PCI-E connectors.. But, my Biostar mobo has 1 PCI PCI-Express x16 slot, plus 2 PCI-Express x1 slots.

I think there seems to be some overall confusion re PCI E and PCI-Express.. Im hoping they are NOT the same thing, so that the defecit of a PCI-E connector on my powersupply will have nothing to do with my ability to utilize my PCI-Express-x16 slot.. Moreover, Im hoping that Geforce 7600GT video card which fits in the single PCI-Express X16 slot will be able to run to its heart's content, not the least concerned that there is no PCI-E connector on my powersupply.

Is this Correct? Or, am I s c r e w e d? thanks for the info...

*** EDIT .. a little more research showed me that the current atx ver2 spec requires this pci-E connector... apparently, the 430w psu that came with my coolermaster centurion 534 mobo was atx ver 1.3... So I replaced with the same case sans psu, and ordered the thermaltake TR2 W0070RUC 430w instead. Only cost 10 bucks more than the integrated pair, and I get a much better psu in the deal, able to power any pci -e peripherals.... Whew... This is my first build in a long time, and Im realizing this undertaking is NOT for the un motivated, thats for sure.. Probably takes 100 hrs of compatibility research the first time.. I used to build pcs all the time back in the 286-486 AT days... Doesnt help much these days, thats for sure. Just have to muddle through it, doing the diligence and matching up compatibilities. In the process, forums like this are invaluable!! Thanks to all :) You guys are saying pci-e slots on the mobo dont require this pci-e 6 pin power connector to be plugged into the mobo anywhere in order to power the pci-e slots.. So I guess it wasnt mandatory that I switch psus. But I did it anyway.. better unit for similar bucks...

You mean a 6-pin power connector for a PCI-E card? The 7600GT don't have it right? As far as I know that card can run utilizing the PCI-e power and don't need extra external supply from a 6-pin. As for your future upgrades you can get a molex to 6-pin pci-e easy.

Yes.. the 6 pin psu connector... So, you guys are saying that the pCI-e slots on the mobo dont require that separate psu pci-e connector from the psu to plug into the mobo anywhere? so its just for separate add ons? Well, i wasnt sure, so i switched to a psu that had it... Cant hurt, and its a better psu for only few bucks more... better safe than sorry.. And its certainly more current as teh current atx ver 2 standard requires it.

Yes, you dont need to worry, the pcie power plugs are pretty much only used by high-end graphics cards. You dont need them to power the slots.

Some cards like high ends does require a 6-pin power supply for extra juice. The 7600GT will run with the power provided by the pci-e slot and does not require a 6-pin power supply. So you're good.

Give me a link of your motherboard. I know there's also a molex power supply to supply extra power from the motherboard to the pci-e slot. But again the 7600GT does not require much power to run so you're still good.

This psu is what came in my case

http://www.newegg.com/product/product.asp?item=N82E16811119111

I got scared when I saw lack of pci-e connector, and switched to the same case w/o the psu:

and bought the following psu as a separate:

Lastly, my mobo is going to be this one:
http://www.newegg.com/product/product.asp?item=N82E16813138026

Hell. . I might as well list the rest of the build for anyone whos interested:

video card:
http://www.newegg.com/product/product.asp?item=N82E16814130062

cpu:
http://www.newegg.com/product/product.asp?item=N82E16819103733
i know there is some argument about this or the 3600+, but not being a confirmed overclocker, Im going with this one... its not primarily a game pc.

ram:
http://www.newegg.com/product/product.asp?item=N82E16820145566
still, I want the better ram in case I decide to oc a little

storage:
http://www.newegg.com/product/product.asp?item=N82E16822144701

and, optical:
http://www.newegg.com/product/product.asp?item=N82E16827136108

Thats about it.. my First build in many years.. Im pretty happy with it. I think it should work together, and deliver a nice performance for the buck, coming in just under $600. Alot of it is from reading your posts and learning from your ideas..

if you dont have a psu with a pci-e connector the video card comes with a package that uses 2 of your +12v connecters.make sure you connect them from two different sources. also make sure your psu has enough am to the 12v. i just got a 7900gs on the mail and my psu doesnt have a pci-e connecter. i beraly have enough amp going to the card so it throwtles down to a minimum. i still get 80+ fps on max everything on bf2 tho.

Ah.. thanks.. just confirms my decision to opt for the more modern psu that has the pci-e connector.
