Correct.

ephekt, can you describe your issue? It's hard to diagnose with no more info than you have provided. What is your system doing or not doing that makes you suspect a power issue?

FWIW, that PSU will easily power a system with 2x the power draw of the specifications you have given. And, there is NO way your current drives and GPU are pulling 40a.

The issue is that certain components stop working either partially or fully when everything is plugged in: the sound card seems to not get enough juice to fully amp the signal, the TV tuner either stops receiving signal entirely or stutters, the NIC starts chattering and dropping packets left and right. The reason I figured it was a power issue was that unplugging a drive and any one of the NIC, audio or TV card allows everything else to function properly. I considered that it might be the board, but I see the same problems on a completely different (brand, model) board.

If it's not a power issue, I sure as hell have no clue what else it could be.

It might be worthwhile to verify that it isn't a software issue by leaving everything connected, but disabling a drive and one of the other things in device manager.

I don't see how this could possibly be a software issue, since the result is the same regardless of which card I pull. Also, disabling the components does nothing, nor does uninstalling their drivers.

[specmike]

Benchmark the video card or play a game with the tuner card and sound card removed from the system. Is this a totally virgin build or, an upgrade. Also, is this after a clean install after format? What OS?

Can you list your complete system specifications and list ALL settings you have made in bios for RAM, CPU, and voltages?

I can't say specifically, but putting it in a general way, simply the possibility that the system is having to deal with too many things at once. It may be an unlikely possibility, but ruling it out as I suggested would take very little time.

Edit: OK, it sounds like you've already done what I suggested.

I've already done this; everything functions normally so long as one card and one drive, or two cards, are unplugged. It doesn't matter which combination is pulled.

Not an upgrade, cloned from another disk of my original Vista 64 install from this same system (I upgrade my boot disk, basically). I've tried these components on another board with a fresh OS, and got the same issue.

Can you list your complete system specifications and list ALL settings you have made in bios for RAM, CPU, and voltages?

What else do you want aside from what I've listed?

IP35 Pro
Q6600 @ 3GHz
4 1GB sticks of Muskin 4-4-4-12 RAM
1 640GB Caviar, 3 500GB RE2s, 250GB 7200.10
Lite On SATA DVD burner
Asus Xonar DX2 - PCI-Express
eVGA 8800GTX
Intel MT dual port gig server NIC - PCI-express
Hauppage PVR-500 - PCI
360 wireless controller and receiver
Some Chinese iPod dock
Wireless MS mouse areceiver
Uplink to 2 port USB hub on my monitor


No voltage changes at all, just bumped the FSB up to 334 or whatever. The only other changes I've made in BIOS were to disable controllers I don't use, but I've already tried turning those off and on one by one and restoring to default.

At a glance, your memory voltage and memory controller voltage need to be changed. Nothing I have seen is stable at CAS4 with stock memory voltage. And, when you have 4 modules as opposed to 1 or 2, the stock memory controller voltage is not adequate.

And, OCing a 266FSB CPU to 333FSB typically requires a small voltage bump. However, we will gladly replace the PSU if you think it is the issue. But, based on what you have posted I don't think it is the PSU. It would most likely work perfectly or not work at all.

In general, an unstable OC and/or improper voltages can cause the issues you are seeing. Do you have the lastest bios installed? ABIT's bios has been flakey off and on with these boards.

From what you stated here, I agree.

Actually, now that you mention it, I did up the voltage from default 1.8 to 2.2v for this RAM. I've also test with only a single stick of RAM with the same results.

The OC is not unstable at all, and I have tested at normal clock speeds on this system, as well at stock speed on a test system, both yielding the same results.

I have the latest stable BIOS, yes, the only thing newer are alpha or beta bins.

Hmmm....I can't put my finger on it but, for some reason it just does not sound like the PSU. Regardless, if you want to RMA, use the link below to start the process:

Just curious, but why do you say this? Granted, I thought this originally as well, but basically ruled out every other possibility.

Thanks, I appreciate your help. I'm still open for sugestions though, since RMAs tend to be a pain and require effort.

As I said above, usually it's all or nothing in a bad PSU. If it was bad, it would be dead.

Well, I picked up the 750 today and the computer works flawlessly now.

It is good to hear that all is well now.

I would try to RMA the 650, because I believe it is defective. Even if you keep the 750, you should still have a known working backup.
