Looking for a Dual Power Supply approx 20A


Recommended Posts

I've often wondered about this, too.
 
Can any of our electronics experts advise if there would be any worthwhile savings in building a fit for purpose power supply (maplins components perhaps). If the answer is yes, maybe that's a worthwhile future project for the mag?

I'm such a cheapskate that  I never throw anything away!

I got mine from my "It'll come in usefull oneday store" AKA loft!

PC's are such a disposable items that you don't need to look too far to find a discarded case complete with power supply.

Afternoon all,
  
 I've got my old 150W PSU from the back of an old PC. I've sorted the wires, and now need to buy all the niggly bits from Maplins. Be aware my electronics knowledge is that which I learn in Physics at GCSE level, so no complicated words like 'rectumfrier'please!
 Heres what I've selected:
10 watt resistor, Which one is suitable for me?!
 
Am I all good to go ahead and buy this stuff so I can have me a power supply?

First try to power-up without the resistor, which is only there to trick the power supply into thinking it has a load attached. Neither of the ones I have used needed it.

 

TBH if you need to buy bits you would be better off going for the ready built PS that Graham posted.
