Tying power rails in series

[stevetob67]

I have a 460 watt HP Server Power Supply and purchased an adaptor board for it that gives me 12 x 12 volt power outlets.
My question is, if I used Diodes or MOSFET's, could I tie two or more outlets together in series to achieve a higher voltage without sacrificing amperage? Or is there a better way of achieving this?
Thank you in advance for any help or advice given, much appreciated.

For you to be able to tie them in series, they would have to be isolated from each other, i.e. not have a common ground which is likely the case. You should check the specs of your particular power supply.

There is no easy way to do what you want with only diodes or mosfets. You could feed those 12 V to a DC to DC converter to get the voltage you want. Depending on what you want to do, it may be worth it to look at another power supply.

Almost certainly not, so far as the outlets from a single supply are concerned.

A DC-DC converter would be the way to go, if you don't need too much current. If you need a lot, cheaper to just buy the right voltage supply in the first place.

In the past I have taken TWO 500 watt 12V Dell Server Power Supplies and put them in series to get 24V. I had to partially disassemble one of them to isolate the DC ground from the chassis ground to accomplish that.

Thank you both for your replies, I thought that this would be the case but there is no harm in asking.

I will just go with the other option I have of putting two identical 24 volt transformers in series so I can still get the 6 amps that they are rated for but achieve the minimum 48 volts I need.

Again thank you for your time.
