weird power problem

[crispyambulance]

I have a new problem now. After getting fed up with the whole computer rebooting after supposedly finishing formatting my former IDE drive only to find out nothing had really happened, I decided "ok, I'll just put it in my old build again and try it there." Well it seemed to have gone fine; I took it out when it started the windows configurator thing.

So I throw in the HDD and my DVD-RW drive into my computer again and boot it up. To my dismay, neither the HDD or DVD drive were recognized. My main hard drive was though. I'm thinking that because they just worked in the other computer, the two drives must be fine themselves. The difference with these two drives is that they connect to the power supply with four pin connectors(the ones that are like rectangular and have four big pins in a horizontal line). My main HDD uses a different connector, and it works fine. Is it possible every single cord of these four pinners could have somehow died when I took my stuff out and then replaced it? I tried every single one in my case to no avail.

Thanks for any idea you can offer 8^).

Crap I'm dumb...edit:
Athlon 64 3700+
2GB Mushkin DDR400 RAM
7800GT
Some DFI LANParty Mobo
120GB(first one) and 80GB(old one) Seagate HDDs, SATA and IDE respectively
Some Antec 500W PSU

Okay, if I get this right, the SATA drive is fine but no IDE drive you connect to the board is recognized by the bios?
You know the IDE drives and their cables are okay since they work well in your other computer?
The drives aren't recognized in the bios of your DFI board and it appears that they're not getting any power. no lights or anything.
All previous attempts to format the IDE hard drive failed and led to a reboot cycle.
If you have another power supply try it. I've never heard of all the molex connectors dieing at once but there's a first time for everything.
What is also likely is that your motherboard is dieing and the IDE connectors just went first.
Give that motherboard a good eyeballing, burnt patches, loose resistors, bulging capacitors, the whole deal and e-mail DFI tech support.

Many thanks.

I looked at the mobo, and everything appears to be ok. Everything except my DVD drive and my IDE HDD is only about four or five months old.

I don't have another compatible PSU so I put the two drives in another computer and they do in fact work. I think it is the power because even if the IDE connections on my mobo were dead, the DVD drive would open if it got power and it opens in another computer. What I originally came here for is if it is possible for these "molex" connectors to have all died at once arbitrarily while everything else to do with the PSU works. I guess all that's left is to RMA the PSU or something.

I have RMA'ed Antec's before and if you have the sales slip they won't give you any grief.
You've just gone into my personal record book,from the sound of it the power supply was dieing which was what started the endlee reboot cycle.

heh cool a record book =)

So, I've never really had to RMA anything. Do I just get a ticket thing like it says on their site, fill out their RMA form, fax it, and then when I get the RMA number mail the PSU?

Follow the instructions from Asus.

All right, well thanks again for everything.
