Does everyone here agree that a 500watt power supply is sufficient enough for a dual MP 1800 board with 4 hard disks, DVDrom, cdrw, dvdrw, and plenty of self powered usb hubs? I'm trying to figure out whats up with my computer and my next stop is to call an electrician.

Yes but
Why don't you explain the problem?
I presume you're getting spontaneous reboots, but those an be caused by other things.
I'd think that if the power is marginal, starting a fredgen freezer or vacuuum cleaner on the same circuit would trigger the problem.

Well ok, here goes. I recently did a post about X quiting out with a sig11 a lot. Its usually about once or twice a week but the other day it did it like 3 times in a row. The only responce I got was that it could be bad ram. So I ran memtest on the machine. Nothin, I have registered ECC ram (required for my board) I've pulled the sound card, no effect. I havent had a spontaneous reboot since I got the new video card. Which gives me the same effect weather I use the comercial nvidia drivers or the open source nv drivers. I dont seem to have the same problem in windows, but I run windows about as much as I run in the street. The only thing I've come up with is that its either the power supply, or I need to get some sort of line conditioner for the plug its pluged into. I have a beautiful surge protector, but I guess that wouldnt stop drops in the power level. Thanks for all your help.

Thanks, that provides more useful information....
I'm guessing it may be the Video drivers. I've seen several posts recently about the NVidia drivers and mouse problems with FC3. Basic lockup issues and mysterious reboots and the like. Something to try.... Get a generic video card to test with.... STAY AWAY from ATI and NVidia Chipsets. This will help eliminate any video driver issues. Another thing to try.... Use the init level 3 instead of 5. If you have problems with crashes still, you know it is related to something other than the video drivers. The text mode is much less stressful for the video drivers.
Post a message to NVidia describing your problem, if not already done. They should support the drivers they have.... and wait for the BIG wheels to turn.
Good Luck, James Kosin
PS: I always have similar problems with my ATI card... and installing FC? and running X right out of the BOX. The install always goes fine weather in Graphical mode or Text mode.

How hot is it? Are you using lmsensors? Are you using smartmontools (see smartmontools.sf.net) smartmontools is very edicational and should be on everyone's computer. Did you run memtest86 long enouhg? if the problem can take days to occur, a 20 minute run might not be enough. Do you have enough fans? Are your cables impedeing air flow? If you have a lot of ATA devices try skinny cables.
Try underclocking the processors? If you still think it's thje mains supply, ask your supplyer can it be tested? When are the peak loads in your area? I was shown graphs of the mains voltage for Busselton in 1965 (it was over-voltage).
You could also consider a UPS which will add value an electrician won't, but if the mains supply isn't the problem then it won't fix the problem.

I would first get one of those testers with the lights you plug into the wall for like 4 bucks, to see if the wiring is correct and grounded properly. Your electric company may have a customer on your grid that at times sucks a huge amount of juice and you get a big sag. I "think" a UPS would keep a steady flow going, but I'd read the box first. I use APC's because I had a cheap one that was toast when the power went off at work, it stunk up the place, the APC was fine. Or like someone said too much heat, run with out the cover and see what happens.
Every couple of months I get a quick beep out of the two UPS's at work when the power goes off for a split second. Power is not always 100% and clean. I still turn on a light switch when I go into a room during a power failure :-)

Under powering electronics can be as devastating as applying too much power. This is especially true with power supplies: Power supplies continue to *attempt* to put out their rated voltage/amperage even though on the back end, it's under powered.
Further, I second Tim's endorsement for APC products: They are reasonably priced and during the 15 years I've been using them, I've never had one let me down.

Well that settles that. I ran all day yesterday with no problems... The memtest ran from 9pm - 1pm with no errors, but at about 7:30pm last night when the washer and dryer were going that it started up again. Also there is a garage band that plays now and again, and I am located (I believe) on the same grid as a football stadium.
Now the real trick, which one do I get.

If you have serious power issues, and it sounds like you do, the best UPS is a Ferroresonant version. That's a technology, not a brand. A ferroresonant UPS uses the laws of physics to get rid of transients by using a very heavy transformer to smooth out any noise. I would also suggest you get a true on line UPS with sinewave output.
These aren't cheap, but they're bullet proof.

Still OT, That depends on how you measure the size of the bullet.
Many years ago I was the engineer at an educational tv transitter site, uhf of course, so we measured our monthly power consumption in gigawatt hours.
One of the measures taken at station build time was a 250KW 3 phase Sola regulation/isolation transformer between us and the power grid, I'd estimate the core and windings went to around the 6000lb mark on the scales. Huge affair on a concrete pad outside the building.
We fought with hum bars in the picture related to the 3 phase solid state hi voltage rectifiers non-zero reverse recovery time, which locked the phase of the voltage going up to the phase of the voltage going down for about 30 microseconds 6 times per cycle, and caused short light bulb life all over the building because of the nearly 2KV spikes that came out of the wall plugs caused by this same effect.
Several years later lightning finally blew that Sola to kingdom come. I mean 6000 lbs of well done Texas Toast. We were a day or so getting enough 500mcm cable rounded up to bypass it and get back on the air. 4 pieces per phase & around 30 feet each long was a bit more copper than was readily available locally.
When we came back up, we were rather surprised that we were no longer troubled by 95% of this picture interference as it could now back out into the power grid and be absorbed much better.
That lightning bolt, the "bullet" if you will, must have been a real hoodoozy, but in the long run it did us a favor. That place had a 1069 foot tower, and I've seen lightning play around on the brackets holding the top beacon and lightning rods, getting that area so hot it outshone the 1320 watts worth of beacon to the point you couldn't see the beacons flashing for a few seconds as I drove toward it, and walk in the door 3 minutes later with absolutely no damages to repair 99% of the time.
Towers like that are, generally speaking, pretty well grounded, the 48 cubic yard base pyramid had a sheet of 12 gauge copper about 8" wide from the pivot ball socket down to its base many feet down, on all 4 sides, installed before it was backfilled after the pour. I'd expect the ground impedance was greater in microhenries than it was in milliohms.

If by "which one" you mean "which UPS", then I'll add a vote for APC. Over the last 15 years, I have consistently had better ownership and use experiences with APC than with anything else in the consumer class. Get one of those.

As I said in my earlier post I had a cheap UPS and an APC, the cheap one burn up P-U ! But the APC was fine. The reason I mentioned your grid is my brother-in-law is an electrician back in Philly and once told me homes are nothing, do you know how much juice it takes to push a train? Stadium lights?
On a OT I'm in Seattle and the baseball stadium roof retracts, yes it dose rain here all the time. But they check the weather report first, because of the thousands of dollars it costs to pull the roof back and forth. BTW we all voted NO to the 1/2 bil. to build it, but somehow it got built. I said I'd never go in that place, but try to tell a 7 YO boy you can't see a baseball game because Daddy is making a political statement, I went. Nice place, but it should be for what we paid!

My brother-in-law worked at a small college, no stadium, and they got their power directly from Pennsylvania Powers main line. It may be like someone flushing the toilet while your in the shower. There's only so much power that can run through the service for the area, and he who has the biggest pipe wins :-) Not to mention biggest bill.

APC and Sola (AKA Best) are well-regarded. I bought an old UPS att auction fo around $AU50; all it needed was a new set of batteirs.
It's rated at 1500VA, can tolerate a lot undervoltage and keep running. Mine's Victron and jusging from info I've googled on it it is a good one, though I'd not previously heard of it.
You do want one with good electronis; most outages are just a few seconds, and if the power is off there's a fair chance you have other things on your min than using the computer.
OTOH you do want it to maintain power while the rock concert's on at the stadium. Minne will do that pretty well indefinitely.

Stick with line interactive technology and stay away from standby or SPS technologies which are both outdated. Both SPS and standby do not filter your power through the battery, so you're not assured of good voltage conditioning.
The advantage of SPS technology is low cost. However, in recent years the cost advantage of SPS has been squashed by line-interactive UPS's which are incredibly inexpensive. There are other UPS types, but they are either obsolescent or targeted at large data-center installations. Also, the only other thing I'd look at is uptime during a power failure. Trust me: In the event of a power failure, the longer your ability to run off of the UPS, the happier your going to be (In the long run...). Buying used is OK if you know the unit your getting is based on line interactive technology and you have extra money left over from the purchase to replace the batteries.
Many UPS's are directly supported in Linux (Which is a really cool). So, before you purchase, you may want to check out the UPS howto:

Hi all,
After receiving this error message on my logfile I found on google that this was a problem with bind versions prior to 9.2.1. But I am using version 9.3.1, with latest patches from FC4.

Is there any possibility that this problem has not been corrected since version 9.2.1?? Apreciate any tip.

It could be or could not be. Depends upon the quality of the power supply, the age of the hard disks (older ones seem to be more of a power hog). All power supplies are not equal, some cheapo "500W" supplies start to fade before delivering a full 500W. What problem are you seeing? With all that hardware in the box I might be thinking that heat is your problem unless the box is well ventilated.
Mike
I would check where your motherboard is pulling the 5v for the usb, if it's pulling it from the 5vsb then it will cause you lot's of problems because most power supply's give 2amps on the 5vsb, each single usb port requires 500ma so if you have 4 usb ports running then you have taken all the 5vsb just on the usb and not got anything for the motherboard to power it self off.
So if you can change the usb to be powered off the normal 5v line which has far more juice...

Si

I'm running a MP2800/antec true330 with 1 scsi hd (15k), 1 ide hd, dvdrom, cd-burner and usb dvd-burner with no problems. What brand/model of power supply are you using? Having 500 watts doesn't mean you have enough power in the right voltages.
Timothy
My Dual Opteron consumes only about 240W, but you should avoid to spin up all 4 harddisks simultaneously.
Tom
To learn whether your computer's power suppy is working, get a power supply tester for about $15 from your favorite computer e-tailer. Turn your power supply off and unplug the cord from both the power supply and the outlet. Open the computer case. Locate the 20-pin power supply connector and disconnect it from the motherboard. Plug it into the tester unit. Plug the electric cord into the wall outlet and turn on the power supply. All 7 LEDs on the power supply should turn on. If one or more does not turn on, replace the power supply.
As Scott Mueller says in his book, bad power supplies are the most common source of PC problems.
Speaking for myself I use either PC Power & Cooling or Antec power supplies. It's amazing how these power supplies just quietly work wonders. I put a PC Power and Cooling 510 watt unit in my latest computer because at full operating temperature it will still deliver 480 watts if needed, and that is about what the latest video cards like the Nvidia need. I can't afford the $500 video card right now, but next year I'll be able to.
I also use 3 Uninterruptible Power Supply units. 2 of these are Belkin supplies and 1 is APC. My first APC unit was defective and the long drive back to the store to exchange it really annoyed me. I bought a Belkin unit, then later on a second Belkin unit, then much later an APC Back UPS XS 800. Together these UPS units have saved me any my wife many an unexpected shutdown and loss of data.
