Still getting surges/browns with UPS

I got this message from my Intel sensor software:

	
	
		
		
			11/14/03 18:07:32



A voltage (+3.3 V) has returned to its recommended range.



11/14/03 18:07:31



A voltage (+3.3 V) has gone outside of its recommended range.

The "acceptible range" I have set up is 4.3 through 2.3

I've gotten these messages on occasion before, but now I have my $100 TrippLite UPS/Line Conditioner hooked up.

What's the deal?

			I think it's just warning you that it's happened, but the UPS corrected for it.

		Alexvrb		Nov 15, 2003
			He said Intel sensor software, so I'd assume that is happening past that. What kind of PSU are you using? Actually, I don't know what the acceptable fluctuations are for the 3.3... but the UPS is cleaning the power that comes through, so its not the outside power that is causing this problem.

		gameboy900		Nov 15, 2003
			Yeah 3.3 volts would be from the PSU itself. So it's either not supplying enough (most likely and the cause for random reboots and stuff) or too much (unlikely cause you'd have fried bits by now). Install Motherboard Monitor and start it's logging. Check to see if the 3.3+ volt (or any of them) have gone off what they're supposed to. Chances are it's a faulty PSU.

		Scared0o0Rabbit		Nov 15, 2003
			my 3.3 runs at 3.42 but hasn't caused any problems yet shrug much as my 5 runs at 4.95, and my 12 runs at 12.17. All those are within acceptable rates, or so I've heard.

		it290		Nov 15, 2003
			Yeah, as others have stated, it's the PSU that's causing those types of problems, but missing the mark by a whole volt is quite a lot. Is that software the soft that came with your motherboard? Try sitting at the BIOS screen and watching the voltages from there for a while. They probably won't fluctuate as much since there isn't anything going on with the machine, though.

I think you misplaced a decimal point somewhere. These variations are all less than 0.2v. The 3.3v line is over by almost 4%, which I think is a bit marginal, but it should be within tolerance.

edit: nm, I guess you were talking about the fluctuations mentioned earlier. It sounds like they're going over rather than under, or the OS shouldn't have survived to log the second reading...

			it's the software that came with my motherboard. no actual problems with my PC seemed to happen. I forgot what brand my PSU is, but before I bought it I asked around the Ars Technica boards to see if it was good one. The all said they were pretty reliable.

		racketboy		Nov 15, 2003
			Here's my settings:

		ExCyber		Nov 15, 2003
			It could possibly be the fault of power distribution components on the mainboard as well (e.g. a bad capacitor), but it doesn't seem to be clear exactly where the measurements are being taken.

		racketboy		Nov 15, 2003
			so what should I do should I even worry? remember, if it wasn't for the software, I wouldn't even know about it since I haven't had any side effects (yet)

		Alexvrb		Nov 16, 2003
			I'm not sure how much you can do. If you had another appropriate PSU available, you could see if yours is having problems. If not, and it was the mainboard... is it under warranty?

		racketboy		Nov 17, 2003
			the mobo is under warrenty, yeah

		racketboy		Nov 17, 2003
			is it a big enough deal to buy a new PSU?

		Alexvrb		Nov 21, 2003
			Ehh... it depends if its the PSU that is at fault. If not, then buying a PSU would be kind of... wasteful. I'd try to borrow a PSU, or get one from a place with an easy-to-abuse return policy. If you still have issues, it may well be the mainboard. Which is why I asked if it was under warranty.

		racketboy		Nov 21, 2003
			just got another message today

		racketboy		Nov 26, 2003
			well I turned up the sensitivity of my TrippLite a few days ago. Just last night it beeped for a little while and all the lights lit up. The power didn't seem to go out. Also I didn't get any messages on my PC. Any thoughts?

		Alexvrb		Nov 28, 2003
			Ask tripplite. Though, it doesn't seem to me that the UPS is the source of the problem.

		racketboy		Nov 28, 2003
			well maybe I just didn't have it turned up enough before. Maybe it corrected the problem after I did

		gameboy900		Nov 28, 2003
			You could of course have really shittiy power comming into your house. You'd be surprised how bad it can be sometimes. You just never noticed it before because alot of equipment is designed to deal with very large power variations.
