    EVGA GQ till 650W are based on the same platform as these GD 450 till 650W. And Raider is a costdown version of Aurum. Raider and Aurum are both really bad in voltage regulation because of the group regulation.

    Yes and?!
    The Design/Layout matters, the Design not so much!
    On a good Design, you do not need good caps, on a shitty one, you do.
    So with a good design, the Teapo SC might last as long (or even longer) than Nippon Chemicon KZE on a really bad and hot design...

    Since there are no 85°C Low ESR capacitors from reputable manufacturers, you only have two places for General Purpose Caps:
    a) Primary Bulk cap.
    b) negative Rails

    And with some 85°C you have higher ripple current rating, so you have to take a good look at the series and read the datasheets...

    Its more complicated, so is a Nippon Chemicon SMR any worse than a KMH?
    One is specified for 1200mArms (120Hz) the other for 2160mArms (120Hz).
    105°C vs 85°C...

    So its just bullshit to say that "it has 85°C, therefore its bad".

    Just look for NMB WTX in this Forum, I made some pics of one of the Server Dual PCB Units I had - made by NMB and both had 85°C Caps...

    Confused... thought I didn't say this.

    To confuse the issue further:
    http://www.repairfaq.org/sam/smpsfaq.htm#smpscoole
    "
    Electrolytic capacitors exist in (at least) two different temperature ratings: 85 C and 105 C. The latter are obviously more temperature resistant. Unfortunately they also tend to have a higher ESR than their 85 C counterparts. So in an application where the heat is due to I^2 * ESR dissipation, the 105 C type may actually be a *worse* choice! If the heat is due to a nearby hot heatsink then 105 C is indeed a better choice.

    No you didn't.
    Was just a statement for the public reading this.

    Because that is what many people say and argue. Even if it is not necessarily true.
