What do I get?

[Monster]

I have an Asus P4C800-E Deluxe w/P4 3.0E. It has 2 GB Corsair PC3200 RAM. 1 BFG GT OC Video Card, 1 DVD Drive, 1 CDR Drive, and 2 WD Raptor 36 GB SATA HDD's.

I went and bought an Enermax All in One Noisetaker EG701AX-VE SFMA PSU, but it doesn't work. The problem is the 12V plug. The PSU-12V plug does not match the mobo-12V plug. The shapes are different, and I can't even get anything to come up on screen. So i'm thinking I got a "too new" PSU for my mobo.

This machine will be used primarily as a game server (F.E.A.R., hehe). It will be run 24x7. I don't want to OC it, don't want to "tweak" it to get the absolute max. I just want it to run sure-and-steady. Given the items listed in the first paragraph, can anyone recommend a PSU that will run all those things AND has a 12V plug that will match the plug on my mobo? I've been looking for PSU's, but so far the only ones i've seen that have the plug that works are in the 300 - 400 watt range, and I don't know if that's enought to power all my stuff 24x7.

Thanks to everyone in advance for their time and help, I really do appreciate it. To be this close to completion and get stuck on something like this is sooooo damn frustrating, I just really hope one of you can help me out...

Four pin 2x2 12V connectors are all the same. I can't fathom why it wouldn't fit. The board isn't too old and the connector isn't too new. If you have a 4-pin connector for 12V, it is what it is.

Look at it closely. You'll see some of the plastic ends are shaped like squares and others are shaped like "D's." This should match your board. Maybe it won't plug in because of a bent pin.

This is what you're looking for. It's a picture of the correct plug from your PSU.

.......You'll see some of the plastic ends are shaped like squares and others are shaped like "D's." ...

That's the problem. The "D" shapes and "square" shapes don't match up. They're actually reversed. For example, if "D" = D shape and "S" = SQUARE shape, then the plug on my mobo looks like this:

SD
DS

And the plug from my PSU looks like this:

DS
SD

Ya see? They're not lined up properly. D should go into D, S into S. But because they're reversed I have D going into S and S into D. I know it sounds confusing, but I don't know how else to explain it...

If I DON'T plug in the 4-pin plug, I can get power, but no video, no beeps, nothing. If I DO plug in the 4-pin plug (I can plug them in, but I have to force them because the shapes are not aligned properly), the fans just jerk a second when I hit the button, and that's it. This is why I thought maybe my PSU was to "new" or to "heavy duty". Maybe the newer, stronger PSU's have their plugs in a different alignement? I dunno... I guess I was hoping to see some one post something like "I Have that board and I use blahblahblah..."..........?? Freakin weird, i've never had such a time with a PSU before....

Sounds like the screwed up in manufacturing. This 2x2 has 2 12V and 2 grounds right? It sounds like the wires aren't even in the right place. The two yellows (12V) should be on the CLIP side of the connector. If they're not, turn the connector around so they do. The fans are "twitching" because the 12V is shorting to ground when you force the connector in. And a Pentium 4 isn't going to post without a 2x2 connector because the CPU isn't getting any juice.

AHHA! It seems that Newegg has dropped the ball. I went looking at the pictures of it on Newegg's site, and it seems i'm supposed to have a 4-pin molex to 4-pin mobo/P4 power cord adapter. The 4-pin I was looking at was the one that "clips" onto the end of the power main. I think they called it a 20+4 Main. But there's another, separate (or is supposed to be) 4-pin plug for the 4-pin plug on the mobo. THAT'S the one i'm looking for/in need of. The power supplies i've had in the past have had this plug "built in", no adapter was necessary. This time is different though it seems. Anyway i'm glad I figured it out, cuz it was driving me nuts that something this simple was becoming so complicated. Thanks for trying to help out guys, you got me thinking

Ah! Good ol' EPS power supply. Yeah.. Those extra four pins are only supposed to go on the end of the ATX connector.

Do you have a 8-pin Molex? 4 12V wires and 4 grounds? You can plug half of that into your 12V header and it'll work.

My Enermax (smaller model but essentially the same, including the SLI rating) came with an 8pin EPS to 4pin ATX 12V CPU adapter. YOu plug it into the EPS 8 pin connector and then plug it into your mobo.

Rest assured that you are using a power supply rated for Dual Procs (Not dual-core but motherboards that have two processor sockets, hence the 8pin connector, yep you are Quad-core ready )

LOL no shit? I do have one of those. I even thought about doing what you suggested but I wasn't sure. I'll have to try it when I get back to work on Monday (i've been slowly building this machine at work). I just finished talking to Newegg, and they're going to send me the adapter. Thanks again jonnyGURU!
