Hmm... is 11.75v a bit on the low side for for a 12v rail?

Under load it drops to 11.65 at times...

Im getting some chunkiness in games, trying to track down what it is exactly.

enermax 350w psu - rig in sig. My gf's comp also has an enermax, hers puts out a fair bit of heat when under load, mine never feels like theres any warm air coming out... in fact, it hardly ever feels like theres ANY air coming out if it o_O... ive destroyed the warrantee by painting it, so i might consider pulling it to pieces and having a looksee.
 
11.65 is probably acceptable, but pretty low. However, if you're reading these settings using software, they're probably wrong. Motherboard sensors are good at measuring changes in voltage, but not very good at telling what the actual voltage is. For example, if it says it's 11.75 and dropping to 11.65, then it probably is dropping .10 volts, but it could be dropping from 12 to 11.90.

Your best bet is to hook up a multimeter and find out what it really is.

hmmm, multimeters, i got a question about those. when i go to the store (radio shack for instance) they have multimeters as cheap as $20, and then some as much as $180... what is the diff? and what should i be looking for? (im just going to be using this for comp stuff and mods - low volts, not sure if that matters)

In all honesty, I have no idea what the more expensive ones do, but I can say that the low end ones will do whatever you want as far as computers go. I have one from there I picked up for 19.95 (or something), and have used it many times to check voltages, etc. from my power supply with no problem.

The more you pay, the more features you get. Usually the cheapest ones are just analog meters (like with a bouncing needle), but I prefer the digital display. With a more expensive one you can get better features like higher-current capabilities, temp measurement, duty cycle, diode testing... most of which you won't need unless you work with electronics alot.

the one i saw for $20 was a digital one....

Ok, I got a digital one for about $20 too. Analog meters can be found for cheaper than that.
 
wow, this went OT pretty quick haha

Ive got an old 70's stz multimeter, i really should get a new battery for it... which i might just do today :)
 
Aida shows 11.8 - 11.6 and as RS3RS said a multy is better. My multy shows 12.01 - 11.86. just be careful not to short anything! I was checking the volts on the backend of my video card when poof. Everthing shut down... I told GOD I would forever be a good person and turned on the rig and it worked. You can petition the lord with prayer:D (j.morrison)

i assume by OT you mean off topic?

well, not really, he wants to measure volts, and for that you use a multimeter, and to get one you need to know about em - so it isn't really that off topic....
