Software uses the BIOS readings. The only way to get accurate PSU voltages is to use a "multimeter".

But make sure both "C1E" and "EIST" are disabled. If they're not both disabled, then that's probably why this fluctuation is occurring.

And again: which Rosewill PSU do you have?

Bingo, I did not realize that what C1E is... turning it off now. I wish my board came with a bios manual..its manual just showed jumpers, etc. Barely anything about it on the nets either, seems a very unpopular board: Biostar H55 HD

Guess I'll have to bust out a laptop and google each term in bios seperately to research it all.

Wait. Are you going to be doing any overclocking?

I had to do a 20% OC to get ram/mobo to advertised timings of 1600.

Wasn't really planning to OC this CPU but now that I opened the can of worms I may as well run with it. i've since put it to 24% OC to reach 3.46GHz since this is listed as max Turbo Boost setting on Intels tech specs.

As expected disabling c1E raised my power from 33W average to about 50ish and fluating 45-55 IDLE. Temps have gone up accordingly as well, from 44C average to 55C average. Not a big deal just thought u guys might appreciate the info.

Are those full-load temperatures, or idle?

ignore the part where i replied with sl-8550eps it is listed next to 'model no.' on my psu but googling turned up a bunch of Apex brand psus.

There is an unlabeled identifier that says rd550n-2dc-sl-slv and google picks up my PSU with this much better.

The 550W marketing is a lie, there is a table showing info at various loads and whatnot and it says 535W max on the side of the PSU itself. -.-

As idle as I get with Windows 7 ultimate 64-bit and having monitoring software and firefox running.

my peak load temp under old settings was 73C (Windows performance experience test) My score is a 7.4 if you don't count the hard drive (which I dont cause im getting a SSD soon)

Its 550W rating is an absolute-maximum. :/ But the +12V wattage rating of 420W means that it's more of a 450W power supply (it might be able to do 450W continuously, but I wouldn't trust it).

Also, now that I've seen a product page for the actual PSU, I am thinking that this PSU is much better suited for a system that isn't being overclocked. I mean, it probably won't be able to handle overclocking very well at all, so your instincts might be right that you may need to get a better one. :/

Wow, those are very high temperatures for this voltage and this overclock. Is your room hot?
