Non SMPS for overclocking?

[JovanD]

Has anyone tried overclocking with a power supply that isn't switch mode, like a battery or linear power supply?

what do you mean?

If you mean a UPS that is an 'offline' UPS, it doesn't much difference. For an online UPS, it should make a noticeable difference, at least for power delivery. If you mean a computer PSU that is just AC to AC that would never work. To my knowledge there isn't anything like that

Im talking about not using a standard ATX power supply.
I mean hooking up a battery directly to motherboard/components. Yea i know you would need 3 different batteries for 12V 5V and 3.3V
The idea is that with something like a car battery you can get +9000W of peak power and smooth(in theory) signal without ripple and choppiness that comes with switching.
Or using a linear power supply, that's basically just a gigantic 220VAC to 12/5/3VAC transformer and than some diodes and capacitor to turn it in to DC, no switching.

Switch modes offer the convenience of lightweight and more efficiency. But it its simply a means to an end. You could get linear PSUs at the right voltage and run them to the right voltage pins on the motherboard - as long as there is sufficient current it wil work. Laptops use batteries so that works albeit not at ATX standards - you want something that holds its charge then can shut the device down before there is insufficient voltage or current to maintain stability.

 

Linear PSUs are preferred by radio hams as switching can cause RF noise if there isn't sufficient switching, but Linear push-pull PSUs are not as efficient. What are you trying to achieve or is this just a bit of fun?

I am recently asking the same thing too and will try soon some tests with regulated power supplies that would provide the different rails. In my opinion performance and stability should improve, specially on overclocking side.
