3.3V rails.. bad.. - Page 2

Basically, the card will suck the juice out of the PSU, and if the PSU can't handle it, well, it will minimize again. The best way to measure your 3.3v rail is to use a multimeter, much more acurate than any type of software, plus they are ~10 bux at a local hardware store.
"The more I read the dumber I get, which is a good thing." It means I'm having to rethink, thanks to you all. Much posting lately has to do with PSU integrity--which makes me remember that all things start at the source. Your post is timely, as I was wondering a couple things that I must have missed in FAQ's lately about PSU and system stability.
I do have a great multimeter,and I can use it. I just need a quick heads-up on how much fluctuation there can be at the 3.3 pins (heck, at all three voltages) is tolerable, and when they should be taken. Under 'load' I only have software to sensor readings to trust (Speedfan, etc)...static readings, I am to take it is where we start then? I have 1.38, 11.62, 3.25 (all vdc) right at the moment--With only browser and speedfan running.
How much tolerance is acceptable--or is it smoothed in the 'good' PSU to precise voltages?

Depends on your standards of how your PSU should preform. Most good PSU's will actually give over the amount of voltage needed, and droop very little between load and idle. For your readouts on your 12v rail, it's fairly low. I don't like generic PSUs for starters, I mean, if your PSU dies, it can take all the components with it as well. Your PSU will still work, but what worries me is "how long till your death" type situation. I usually set aside 70+ bux for a PSU, keeping in mind the value of my components and what I am getting. I mean, the PSU is highly underrated when it comes to spending money on computer parts. Which can lead to a major downfall for people.

If that is the case then USD$36.00 will get you..this..by the maker's of OCZ and for the money will offer you good performance with reasonable stabilty.

Hmm.. Well can you vouch for it being from makers of OCZ and being very reliable?

I personly woululd not trust teh software. but the PSU is a bit sceatchy....

Smart Garduan shows my 12V rail @ 11.39V most times... and my 5V @ 4.89V but I would still never trust it. The only way to tell is if you use a volt-metter or your PC starts to mess up. like random reboots under stress....

Ermm. Speedfan, Everest, and Asus PC Probe show it crap. Plus now at my max overclock my computer restarts sometimes while playing CS:S. so yeah, its pretty well screwed up.
