Full Version: Are These Rails Really Bad?

It seems like when i turn down my fans. my games have higher FPS... but i have to turn down the fans and restart the computer before loading up the game before it works. If the fans are turned to a higher FPS i have to restart the computer with the fans turned low for them to work properly.

here are my rails:
Orange (3.3) : 4.35
Red( 5) : 6.43
Yellow (12) : 14.95

These were taken with a Multimeter from the molex plugs.

It may very well be your power supply. Those rails are way out of the +/- 5% spec.

Look into buying a new power supply. Quickly.

yea man, get a new PSU fast! Those rails are really quite bad!

BAD VERY FREAKIN BAD Actually your stuff should be dead by now...I've had PSUs that came with cases do better than that...If you have a secodnrig inthehouseI would suggest usingit,or remove any OCs and as much load as possible form the PSU and see if it improves. I would be buying a new PSU NOW if it was me...(and I would have ripped the power cable from the wall while i was at it smile.gif)

withstupid.gif Yeah I wouldnt use that machine at all. You would be better off running to bestbuy and and picking up a budget PSU and using that for the time being, you can always return it later.

yes take the advice from the other posts and shut off that pc and dont use that psu again.....that isnt good at all, consider yourself lucky something isnt dead by now.

what psu is it? i can't remember seeing a psu without overvolt protection... i mean, it's been a while since i've had a pos psu in service, not that psu's without ovp don't exist

I'm curious as to what make that PSU is too. I haven't even seen an Aspire or Allied that bad. ohmy.gif

i been using this PSU for 4 years already...in the bios such the rails are prety close though.... could my Multimeter be wrong? i did serveral tests at several different places and it all seems the same with the MUltimeter and i even done a 5v test on the main connection to the motherboard and still same results.

While the values measured are certainly worringly high, they might not be high enough to trigger OVP circuitry.
Just looking through some OVP values on newegg (in the cases where they are provided) shows they are higher than you might expect.
For example, on some of these FSP models.

The rails are certainly running way out of spec if they are consistently those values though (I'll assume because they are from a DMM that they are accurate).

edit - If the PSU (what's the model/spec btw?) is 4 years old you could probably do with a replacement anyway. Start shopping!

Thermaltake 480w Purepower Xaser 3 Silent

i really don't want to buy another PSU if i don't have too.. thats how come iam making 100% sure. 4 years ago i went from a 400w Allied Power PSU to this Thermaltake.... and the Allied powered was around 30-40bux and the Thermaltake was about 100-120ish 4 years ago.

If it were between the BIOS' readings and a multimeter's readings, I'd trust the multimeter every time. If you still need more convincing, try another meter. Also, if your PSU has lasted over 4 years, and it says Thermaltake on it - I'd say you got your moneys worth out of it (Tt's older PSU's sucked IMO, not too sure about the newer ones). If you decide to replace the PSU, which we all think you should, consider something similar to this Antec 500W. It's only $60 after the rebate with free shipping.
jammin
If you want to be absolutely sure, then knock yourself out.
Try a different multimeter if you want, measure from different points, keep your meter plugged in for a couple of hours and monitor any changes.
Do whatever you feel comfortable with.
I would even say check inside the PSU and check caps for bulging etc. and see if there are any pots you could adjust, but only if you know what you are doing.

If you do all that (if that's what it would take to convince you) and it still seems your voltages are way off then you don't really have much choice.

Well did you try calling thermaltake? If your that concerned and don't want to spend any money on a new one go to the source.

It could be your multi too... at those Vs, your HW should be dead... Had the same thing happen to me when i used a readio shack multi... switched over to a craftsman and voila, instant goodness

thanks. i actually have a Tagan Modular PSU in mind. so i can try and keep the case clean looking.

and then my next up for choice is Seasonic.

OCZ would be my first choice if there wasn't LED lights on the fan.

now another thing iam trying to figure out with a new purchase is how much watts do i need? 500? 600? or more?

EDIT: WHOA 60 dollars for a 500w modular? i guess what do i have to lose... i'll try and place an order in as soon as possible. money is kinda scarce right now for me..... i really hope this solves my problem with me needing to set my fans a certaint RPM before loading up a game.

see iam hoping thats the case... PSU's are expensive... and this one has been good to me for 4 years already.. i don't see a reason to change it.

but iam using a cheapo Digtek multimeter that came free with my Belkin computer tools (which i also gotten for free..)
Raven65
personally I'd stay away from modulars. Also your running s bsrton right now which doesn't require as much wattage as the newer stuff. I wouldn't get anything less than a 600W PSU. Why buy a new psu if you upgrade.

yep... See if you can scrounge up a decent multi-meter and test it that way. thumbs-up.gif

Those readings are way off, but they're so far off that I really wonder if they're correct. I mean Tt PSUs are bad, but they're not that bad. I think trying a higher quality multimeter is a good idea.

bingo i just ruled out the volts. its nearly perfect except for the 5v which is only off by A LITTLE. the 12 an 3.3 is nearly perfect.
I went from Digtek Digital (which gave really wrong readings) to a Radioshack analog multimeter and the readings were nearly perfect on the analog.

i actually fixed the problem it looks like the PSU wasn't the corperate heres what OCforums found out for me which fixed the problem:

nice nice, see, people at ocforums are so retro, they are all over the AGP stuff, but on OCC, we still keep the AGP in reserve, but we roll the PCI-e usually laugh.gif

The vgu is too..... can't.... say .... it.... too cold?!?!

Well that's just blasphemy!!! tongue.gif

Glad you got it worked out. That's a VERY odd problem, but if it's fixed, that's all that matters smile.gif

That is very odd problem indeed.
Good that you got it worked out though, and it cost you nothing at all. Result! smile.gif

ya it does sound like blasphemy but it is a software bug.. so maybe nvidia will get a fix on this soon.

This time of the year the house is freezing, the case temp is always mid 20's and the processor WITH ITS FAN TURNED off is at high 30's.... That Thermalright SI-97A is probly my best purchase out of this whole rig.... stupid Nvidia.. this makes me want to return back to ATI.
