Voltage mod

[slicedtoad]

So I'm being cheap here and wondering if I can save a buck.
I have a water pump that needs 16V to work at full speed but PSUs are not designed with 16V outputs.

It's a Corsair hx 750W psu and I don't mind modifying the cables but I'd prefer not to open the case (7 year warranty). I have a nice electronics store nearby (resistors and capacitors and such) and have decent soldering experience.

Apparently I've forgotten my basic electricity course I took some years ago and have no idea if this kind of mod makes sense. Any electricians here that could enlighten me and perhaps point me in a direction?

how many watts does the pump need to work?.


and what is the amp's output for the pci-e cable


id recomend not opening up psu


if it can be done best doing it through a cable (personally though, i would buy another psu for it)

I'm using the pump to cool my computer so another psu would not be feasible.

The correct way would be to buy this: http://martinsliquidlab.org/2011/02/28/koolance-ctr-spd24-10-24-volt-speed-controller/

It costs $50 though, and i don't need variance.

The pump is a d5-strong. no idea how many watts it need but here's an article on it:

Since you require a step up of the voltage there is no way of getting the higher voltage without using a DC to DC power supply.

The Koolance CTR-SPD24 10-24 Volt Speed Controller does the DC to DC conversion along with the inclusion of variable voltage output whereas you just want a fixed output. You will have to use the same type of DC to DC conversion circuit and it involves more than resistors and capacitors.
