    My ATX12V on 12V2 produces 22A

    12V1 22A
    12V3 & 12V4 produce 25A

    All 12V's together give 760W

    I am getting a PSU upgrade anyway to fit my current case.

    I am hesitating between a:
    - Corsair TX650
    - Corsair TX750
    - XFX 750 W Black Edition
    - Thermaltake Toughpower XT 750W

    These all have single rails. The best choice seems Corsair or XFX according to the reviews. XFX has slightly better efficiency while Corsair has longer warranty. I still have 6 days to decide.

    Go for a single rail psu. Split rails = ****ty overclock. Not everyone will say this, but not everyone has hwbot records.

    Tell me about your issue is greater detail.

    I edited the first post with more detail

    This is my CPU in a review.

    I am probably getting a Corsair or Seasonic one because of recommendations from these forums.

    The Seasonic X750 Gold was marked down $40 just two days ago on Newegg, I don't see the discount code anymore though.

    I noticed. But I am going to try a single rail PSU. See if it makes a difference.

    Hasn't Seasonic replaced the X750 with the X760?

    hmm, I hadn't even seen that one. Newegg says it is a deactivated item, maybe the 750 is replacing the 760.

    Maybe it's just not fully released yet, I see the 760 but not the 750 on Seasonic's site.

    I'm 100 percent certain the X-760 replaces the X-750. You used to be able to get the X-750 over here, but now most places only have the X-760.

    Maybe Newegg are getting rid of older stock, hence why there is no X760 and the price reduction. What better way to sell old stuff than not to provide the new stuff until the old stuff is sold?!

    I noticed 4.1 ghz is pretty stable here

    Whenever I try 4.4ghz I don't think 22A is enough :/

    I always blamed my mobo or cpu...

    It can run fine for one hour for example. But then I get BSOD. I restart then immediately BSOD again.

    I think it is because my PSU heats up and is then able to produce less amps maybe. Is this possible?

    I think I am going with a single rail setup but I have to hold on 1 more month :(

    I tried finding a pattern on the internet. And it looks like multi rails have most issues regarding overclocking sandy bridge.

    I think Corsair TX650 or TX750 are the best single rails for its price. or the AX650 being next after these.

    I was also thinking about overheating VRMs since it's a cheap board.

    I think I will first get my PSU upgrade then and ivy + Z75/Z77 afterwards. For me every frequency counts.
