Just got a new Thermaltake 480 Silent Purepower along with a Tsunami Dream case, according to the ATI tool motherboard monitor, the powersupply's 12v is running at around 12.4 to 12.5, should I be worried about this? Its not "alerting" me of anything but I wasnt sure if this was too high. Its a good powersupply but

Power supply:
http://www.newegg.com/app/viewproductdesc.asp?description=17-153-007&DEPA=0

But I was kinda worried if its going to handle the 2 120 mm fans 1 90mm fan, along with 2 5400 rpm HD's, cdrom, sb audigy and 9600 XT with ease. And to answer my own question, since I wont be stressing every single device at once it should be able to, but whats up with the 12v rail, is that normal? It seems to stay steady around 12.4-5

Questions, comments?
 
i'm pretty sure if it's within .5v of the rated voltage then ur ok.
 
Definately not a good sign heh, had a friend play World of Warcraft while i was laying down and he came to notify me about a half hour later that it shutdown by itself. Apun inspection I smelt a slight burn from the PC, and found its coming from the Power supply. Its that "new" smell things have when they have just been unwrapped mixed with a burn.

Bah.

Typing from it at the moment, the smell is gone and everything seems to be acting normal. Comments?

thats TT for you :(
 
Go into your BIOS and check the voltage there first. Software is notoriously bad at voltage monitoring. Double check with a real volt meter to be sure.
 
a burning smell is either really really bad or normal :p

when quality supplies are made they get a substantial "burnin" after manufacturing

It's probably potting varnish...

After they wind the transformers and inductors used in power supplies, they dip them in varnish to keep the wires securely in place and well insulated from each other. During operation, the cores and windings of these magnetics heat up and some chemicals from the varnish are gassed out. It reeks at first, but it'll go away after a while.

We go through this at work. One of my company's products has twenty 2KW switching power supplies, each containing 3 magnetics that are potted in varnish. When we burn the thing in at first, you can probably get high by putting your face near the power supplies :D

supplies that are trying to cut costs
(for whatever reason, from sheer profit to putting the money towards better components and still being competative)
might not get the same level of burnin, and thus continue to off gas after you get it


then there is that other burning smell, the kind you get with burned plastic wire coating, PCB or components :eek:

you can likely adjust a high baseline voltage, provided you calibrate the software reading taken off the SMBus first to the actual reading with a Multimeter as mentioned

(SMBus = System Management Bus, where the BIOS and all other aps pull the value,
good for observing or logging fluctuations, not so good for definative values)
How to adjust your voltage lines (and list of psu's with internal pots) by computerpro3
of course you need a digital multimeter and you have to pop the top and void the warranty
(unless your real tricky and solvent the sticker off somehow)

why you want to have your rails as close to the baseline value as possible is
that your supply has a transient response of 5%, if the baseline is too high,
under some circumstances it might overshoot the allowed value in the spec,
even though its functioning within its own parameters,
if you have a supply with a tighter than spec transient response (load regulation) say 3% or 1%,
your able to bump the baseline voltage without fearing the overshoots ;)

Basic 5% range is
+12V....11.4V to 12.6V
+5V......4.75V to 5.25V
+3.3V...3.135V to 3.465V
 
i got one of those for christmas, and i love it. i can have all my harddrives in at once and everything else. it is 100 % stable and it lowered my case temp by atleast 10 degrees, which means you can overclock even more, its actually cold to the touch, my old one was just as hot as the heatsink usually.
