Stupid simple is what i called it .
And i also grouped my wires together , no led , no resistor , and no bananna plugs .
My cost was also zero dollars .
And more amperage than you could possible every need to feed your charger .
Hey on the red and black lead for the resistor , use the fan for the prosessor to draw the current and have and extra fan for cooling your battery ,s or favorite beverage .
You should have had a fan , on the mother board cooling the prosessor .

In My experience computer PSUs struggle to maintain 12v under higher loads...

...but the main issue is that more and more clubs are simply banning them as they feel they are an unnecessary danger, especially when for about $Aus60 you can get a 12v, 13A PS with short circuit protection etc etc from an electronics supply chain...

Considering the amounts we spend on some RC components ($A250+ for a speedy, $A400+ for radio gear) its seems silly to me to try and cut corners with something that could potentially kill you

I don't know what computer PSes others are using, but most modern ATX PSes have short circuit protection and many other features built in. My PS, for instance, won't even turn on if there is a short circuit.

Between that and the fact that you don't actually modify the PS in any way (just group wires), it seems silly to call them dangerous. Heck, if you didn't want to, you wouldn't even have to open up the PS case, just work on the wires. These PSes hold up for years of solid continuous use in computers. Of course, if other ppl are modifying their PSes (like putting in large resistors to keep it always-on rather than just under load), I could see them being dangerous.

Has anybody seen a well-done computer PS do something dangerous (that is, more dangerous than it already is using LiPos for instance ).

Plus, as somebody who is brand new like I am, I want to save the money for other things (for instance, I have not invested in a quality radio yet or lipos for that matter (still just running NiMH)).

Lipos are only "dangerous" because far too many people are lazy and don't take the care they should...

I've never yet seen a lipo do anything "dangerous" in person... I've been using them for about 3 years now...but I've seen 1 PS catch fire and another start shocking the user every time he went near it... I have also seen more than one set of NiMH explode...

Its all relative... having used a converted PS and a proper "built for the job" commercial power supply, I know which I would rather have

Agreed, 1000% .

I wonder what caused the fire. Perhaps no short-circuit protection, or mis-configured wires? Bad soldering (loose connections causing short-circuits)? etc. I also wonder about the shocking. With a properly-grounded modern PS (that's well wired as well), that should not happen.

Even then though, I agree that commercial PSes are a lot better direction to go in the long-run. I eventually plan to "upgrade" to one once my other major purchases have been made.

I'm glad I haven't seen a NiMH explode yet. I've heard they go quite spectacularly as opposed to just "fire starters" that lipos tend to be.

Well, there's no way I'll argue that point . I definitely plan to upgrade to a "real" commercial PS eventually. In the meantime though, I would rather that $60-80 go towards a radio or lipos .

so what is everyones descision? Make my own???? I have the hyperion duo charger. I was using a 12v car batt and the fans didnt turn on the charger. it took me 50 mins for 3400 mah. Not bad. But i know it can go faster.

How many watt PC PSU would one recommend?
