    Default FLASHBACK! 2009 "Myths" page from PC Power & Cooling!!!

    I was think about this the other day and went to archive.org to retrieve it. I copied over to my site for prosperity.

    I highlighted in red the points that made me LOL....

    http://jongerow.com/PCPower.html

    "Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature."

    Umm... Connectors cost more than copper wire.

    "The voltage drop can be as much as would occur in 2 feet of standard wire."

    Umm... no.

    "The smaller parts can handle less current, so the maximum power available with the 120mm design is limited."

    No. There are no parts in the PSU that have to be so large that they need to reside where the fan is located. True, that you could fit larger heatsinks, but a more efficient design doesn't need heatsinks that large.

    "the 120's fan speed can double and the noise level can jump by up to 20dB."

    Clearly they did not understand airflow at the time.

    "a well-engineered PSU with a rear-mounted 80mm fan will provide superior performance and reliability (due to larger components) at a noise level comparable to a PSU equipped with a 120mm fan."

    I've yet to see any 80MM fan quieter than any 120mm fan (while providing an equivalent amount of cooling) at any RPM.

    "a multi-rail 12-volt design has distribution losses of up to 30% of the power supply's rating. Those losses occur because power literally gets "trapped" on under-utilized rails.For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system."

    This one really kills me. "Trapped power"??? Well... Yeah... if you evenly divide three 20A rails off a 720W +12V parent rail.... BUT WHO DOES THAT?!?!!

    I plan to "pretty up" the page showing pictures from advertisements from the late 19th, early 20th century, depicting doctors smoking cigarettes and children doing cocaine for health reasons.

    You know... Telling people to do things wrong before we realized we were wrong.

    I always laugh at number seven cause it basically reads "there's no way two fans could be better than one!"

    I know that they're all pretty egregiously bad, but over time it just seems more silly than it did when they originally pushed these out.

    If you look at a PSU with two 80mm fans, it typically has them offset. Sure, they (PCP&C) feel it "should" exhaust ALL heat from the PSU. But that first fan IS spot cooling (as they accuse) and that's ideal for keeping the second fan from spinning too fast!!!

    At least with two fans, if one fails there is still some cooling.

    If you have ever played with a PSU w/ an 80mm fan you wouldn't put one in your rig.

    All my PCs have 80mm fans in their power supply, even the 5 running Windows 10. Now that I think about it, I don't have a PC supply that does not use an 80mm fan.

    Though that's not the ideal scenario.

    I will say, given today's technology, you should be able to make a very small depth PSU if we go back to 80mm exhaust fans. Current PSUs have a lot of "dead space" because the PSU has to be at least 125mm deep!

    Can the ATX12VO be smaller?

    Absolutely.
