  válasz Qru #26306 üzenetére

  1000w-ig nem nagyon van oylan táp, aminek több tényleges 12v ága van, mind egy tőről fakad, csak "virtuális" ágak.
  Ezt minden oldalon leírom, de ugy tűnik senkinek nem tűnik fel.
  Tessék már utána olvasni. angolul értők előnyben

  kiemelném a lényeget:

  [I]But some people claim they can overclock better, etc. with a single +12V rail PSU

  B.S. It's a placebo effect. The reality is that their previous PSU was defective or just wasn't as good as their current unit. If the old PSU was a cheap-o unit with four +12V rails and the new one is a PCP&C with one +12V rail, the new one isn't overclocking better because it's a single +12V rail unit. It's overclocking better because the old PSU was crap. It's only coincidental if the old PSU had multiple +12V rails and the current one has just one.

  The only "problem" the occurs with multiple +12V rails is that when a +12V rail is overloaded (for example: more than 20A is being demanded from a rail set to only deliver up to 20A), the PSU shuts down. Since there are no "limits" on single +12V rail PSU's, you can not overload the rails and cause them to shut down..... unless you're using a "too-small" PSU in the first place. Single +12V rails do not have better voltage regulation, do not have better ripple filtering, etc. unless the PSU is better to begin with.[/I]
