PSU slowly dying?

I figured with all these "is my psu enough" threads, I'd throw one in slightly different.

I have:
EVGA 680i
Q6600 @ 3.6Ghz
4x1Gb ddr1066
4x320gb SATA drives
1xPATA DVD/RW
GTX260 @ 756/1200
8800GTS640 @ 700/1000
X-Fi Titanium Pro PCI-E
OCZ GameXtreme 600w

Here's the issue I'm running into. I used to have good voltages on 3.3v, 5v, and 12v. Almost spot on and steady. Now that I've upgraded to a GTX260, and have left the 8800GTS640 in and dedicated it to physx (which obviously isn't utilized all the time), I've noticed my voltages are no longer steady, and are below/above the standard ratings. 3.3v is now 3.18v, 5v is now 4.8v, and 12v is now 12.45v.

Since I had left the older GTS in, I was planning on upgrading in the near future anyway, but should I expedite that upgrade? I was thinking of the Thermaltake Toughpower 750w, or Hiper 880w. I wanted some room to expand with - so would the 750w cover the components now with room to grow in the future?
 
Well a voltage change considering what you are running isn't really surprising . I wouldn't be too worried but I also wouldn't leave it like that for a long period of time, I would probably expedite the upgrade in a reasonable time frame just to be on the safe side.
 
Thanks, right now I've been shutting the system down when I won't be using it for long periods of time so as to not add un-needed stress. Think the Toughpower 750 would handle things or should I go for the Hiper 880?
 
Brand doesn't really make a difference to me, but what's the difference between having seperate 12v rails vs a single 12v rails? That's the one thing that attractewd me to the tagan was it's ability to combine the seperate rails into a single rail.

All current Corsair builds are either Seasonic or CWT internal and are all single rail designs. They advertise quad rails on many in order to meet official ATX 2.0 PSU spec, but they are really single rail units. Corsair is a safe bet, while Tagan you have to research unit by unit, same some are very poor quality while others are quite good. All the Corsairs are good. All Seasonics, PC Power & Cooling, Silverstone, and Coolermaster Real Power Pro PSUs are good as well. Brand is very important with PSUs, as quality varies widely.
 
I meant that I'm not loyal to any particular brand. Of course I want a good PSU (reason for the thread as I don't think the OCZ I have - although great warranty support- is/will cut it anymore for my system). I've been looking at the Corsair's, Thermaltake Toughpower, Hiper, PC P.&C., and Enermax's. Never even considered the Coolermaster Realpower's before.

Are you using software to measure the voltages? If so, totally disregard any software readings. They are not accurate. Not even fairly accurate or close.You need to use a digital multi-meter for accurate voltage readings.

Nope, using a dmm. I noticed the voltages in bios at first, then got out the dmm to confirm and came up with lower readings than what was reported in bios. Been doing this stuff for waaaay too long to know to not trust the software/bios. But that's just one of those questions that has to be asked ;)
