    Those look better. I could live with those numbers if I had to/for the time being. As long as it's stable.

    re: IBT I read somewhere that IBT was the absolute worst thing you could make a CPU endure. They, multiple peoples posts, referred to it as totally unnecessary and even harmful to the CPU. Is that still some peoples consensus of it?

    yes i think i will stay away from ibt for now and just use prime95, does anyone know what actually runs on the 3.3v rail ? or does it depend on what mother board im using, if i knew what ran on the 3.3v maybe i could narrow it down to something, i don't think it would be the psu its self as that's tested fine on the psu tester, al lights were green, tho id rather i had a digital psu tester

    Meh, don't go giving the PSU tester results too much weight. The load tester is your configured system, not any hand-held PSU tester thats basically a go/no-go checker.

    I believe, I say believe, on this board 3.3 powers the memory. I may be wrong there though.
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

    #2 - G.Skill RAM Configurator for your boardSamsung Memory for your boardLatest AMD Chipset Drivers/WindowsLatest AMD Graphics Drivers/WindowsLatest Intel Drivers

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
    ____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

    In the past, the 3.3V and 5V rails were used by the CPU, but that was changed quite a while ago. Now the 12V rail is used to provide power to the CPU, indirectly through the CPU's VRMs. The 3.3V and 5V rails are not used much by the board itself anymore, but still should be within spec. HDDs are provided with all three voltages, although some may not use the 3.3V rail. 99.999% of SSDs only use the 5V rail. The amount of power drives use is low compared to the CPU and video cards.

    Your PSU is a bit odd IMO that the 3.3V and 5V rails seem to droop as much as they do, while the 12V rail is quite solid and consistent. That is the case while using a DC to DC conversion design for the 3.3V and 5V rails, meaning they are derived from the 12V rail and not from their own dedicated AC to DC circuitry. That design is found in the best current PSUs and is considered to be a superior design.

    Found a good review of this PSU: Thermaltake Toughpower XT 775W Review

    It received a good review, although the minor weak points included a somewhat low regulation on the 3.3V and 5V rails, but within ATX spec. It looks like the 12V rail was tweaked up a bit after the review found it to be a bit low at low load, yours at 12.4V+ is why I say that.

    You might want to do what you did with the 24 pin cable to all the other cables. Meaning disconnect them and plug them in again and be sure the pins are all the way in as you did with the 24 pin cable, a great idea (which I do as much as possible.)

    OTOH, age might be showing up now, as your PSU might be about four years old now? The parts in a PSU do suffer the affect of age over time, particularly the filter capacitors that are a main part of keeping voltages stable. Your voltages are not terrible now that you "fixed" things a bit, but I would also be bothered by those readings since they aren't perfect.

    Do you use any extension cables in that PC? Or adapter cables of some kind? They could add resistance to the load the PSU "sees" and contribute to the voltage droop. Otherwise I don't see any strange or terrible loads on the PSU.

    If your PC is stable and functions fine, I would not worry about this to much, but you might want to put a new PSU on your short list of future upgrades.

    thanks parsec, all the reading so far are without any extensions added, now i have bought all new extensions and this time a better brand, Silverstone, i installed the extensions and did what i wrote above, pushing every wire in with a very small screw driver, my readings changed, this time for a slight better reading, my +3.3v idle are now 3.296v and under lead 3.264v so much much better, my +5v idle 4.946v and loaded 4.865v the +12v is something iv never had any probs with reading 12.493v idle and 12.429v loaded.
    i went and read the review from the link you gave above and i can see from there testing that im pretty much alright with these readings, i bought the psu brand new from Computer Hardware - Scan.co.uk just over a year ago

    thanks for your time and help
