This is what I don't understand. The guy simply asked the viability of making his own PSU's to supply power to the 6-pin PCI-E video card slots only. (not entire systems which require all the chips / circuitry / logic)
It was a simple question of "would this be something I could do?", and that response of yours is acting like he said "fuck all you imma do it anyway"
Actually what he asked had to do with ganging up small PSUs in order to make, effectively, one big one. That's incredibly simple - you need nothing more than a bunch of diodes (albeit, big ones) and a bunch of soldering. But then what if current-hogging ensues because you didn't know to include components to equalize the voltage between the various PSUs and they start dying right and left? If the OP doesn't know what a P/N junction is, how a diode works, what forward/reverse bias is, etc., then how would he know how to fix the inevitable problem that pops up when there is one? How would he know how to fix the design flaw in my aforementioned example, or other unknowns? As for "fuck all you imma do it anyway", that's what it seemed like. The question was essentially phrased like.. "I wanna do this, tell me how!"
