Knock it off, guys. All it takes for the argument to end is for one of you to STFU.
Back to the topic at hand, the original post did sound too confident about things. I want to make sure that when I plug my True480 into my Chaintech NF4 Ultra that it won't screw anything up.

You STFU
No seriously, the argument is done.
You will hurt nothing with that power supply. New 24 pin boards work with a 20 or 24 pin power supply. I am using a Nforce 4 board with my Antec True430. I am low on my 12v rail (11.5v), but that is because I have a video card that does not have any additional power connectors (the only 6600GT out there that doesn't have any I believe). My card gets all its power from the PCI Express slot.
I decided just to go ahead and get an 24 pin OCZ power supply, just to be future proof.
Some cards come with the 6-pin PCIe power connector (or you can purchase it seperately). So I don't get it about the PCIe slot powering the card.Originally posted by: UsandThem

My Leadtek 6600GT card, does not have any additional power connections.
I have the Gigabyte GA-K8NF-9. It uses the new 24 pin power connection (BATX), but can also use a 20 pin one as well.
The four additional pins are fore the PCI Express slot.
So my board has the 4 pin connection (for the CPU) and the regular power connection.
There are no other places to get power from. This is my Link
The AGP version has an additional power connection

That power supply should be fine, however I have never heard of that company and don't know much about them. I would personally would go with the Tagan Series for $79.00, as it has 28a on the 12v, but hey, what do I know according to some
The one that I am talking about is this. It got really good reviews:

cheers. Silverstone are a pretty big company i guess, specialising in cases, cooling and power-supplies. a lot of their stuff has been reviewed here.
I read this whole topic but I still have some questions. I have an x800xl w/no external power connection I also only have a 20 pin psu do I need to get a 24pin? Im running my system right now with the 20pin and have not noticed any problems.
I think a quickie electronics lesson is in order.
The OP mentioned using a 2-molex connector to provide power to a 6-pin adapter for a PCIe graphics card. (This actually applies to pretty much any use of splitters/adapters and power supplies in general.)
DO NOTE THAT USING TWO MOLEX CONNECTORS FROM THE SAME WIRE (IE A BRANCH CONNECTOR FURTHER DOWN THE SAME WIRE) IS NOT WHAT A TWO-MOLEX CONNECTOR ADAPTER WAS INTENDED FOR.
Because of the design/layout of those wires, ALL of the current must flow through the first part of the wire. So, if you are trying to draw a theoretical maximum of 72W from each molex connector, you are still drawing a nice 144W from the entire line. Imagine an A/C duct. Would you use the same 12" ducting that goes out to each individual room to feed from the A/C itself? No, you'd most likely use a 24" duct or (and this doesn't really happen but you get the idea) 2 12" ducts. Let's look at it in a graphical way... let = represent a wire carrying a large amount of current (too much current), and - represent a wire carrying up to its rated current. let | represent a molex connector.
If you attempt to use two molex connectors from the same line to power your adapter, you will create this situation:
===========|---------------|
This is because both connectors are sharing a common conductor (even though they are technically in parallel). I cannot think how to explain it much better, but just remember that all of your power has to come from somewhere, and if you try to split something too many times you will regret it later.
So don't go cheap out and buy an L&C 400W PSU because it's $50 less, and then using a molex splitter to use the same line that goes to your HDD with your PCIe adapter. I can pretty much guarntee you will set fire to your PSU if it lasts long enough (and since we're talking about cheap PSUs there probably isn't any kind of OC/OL protection), but in either case you will be sacraficing that PSU and then still have to pay the price of the more expensive PSU, as well as any other components the PSU destroys on its way down.
My national electric code teacher always says, "Forget about guns - we should have a 10-day waiting period on screwdrivers; anyone can go out and buy one and think they know what they are doing."
Just remember, splitters and adapters are designed to make things do something the manufacturer did not intend for you to do (if they intended for you to do it they would've made it so you could do it without any extra splitters or adapters!), as such use of those devices should be reserved for the most extreme and/or limited of circumstances, and only when you've done your homework to know that it's 110% safe and approved. I mean, honestly, I can mount a chevy 454 to a lawnmower given enough adapters, but is that really a good idea?
To reitterate, all the power must come from somewhere.
I would much rather take the time to answer peoples electronics questions about matters like this before they are put into practice, than listen to people whine and cry when XYZ psu fried their $2200 playtoy mommy and daddy bought them.
That's about all I've got to complain about this time around =).

I wasn't talking about the $350 PSUs. An Enermax or Antec is pretty much what I was refering to.
That wasn't really my point though.
I just want people to be aware about the effects of series and parallel current before they go out and buy adapters and splitters and stuff for their power supply.
This is more of safety thing than anything. I just don't think you can overlook this aspect when talking about this kind of topic.

Thank you! I was afraid people would mis-interpret what I said and blow me off, but I'm glad to see that it's being taken seriously. I will try to put together a better representation of the hazards and risks posed by these kinds of issues so that people with little to no electrical background may comprehend the deeper meaning behind it. But again, I'm just glad people took it the right way =).
