Hey, i ran into some guy saying that 20 to 24 pins power supply adapter were junk, cause of amperage loss when splitting wires to fill the 4 extra pins. What do you think?
Load of rubbish. All in all, it all comes from the same source. The +5v from a molex connector comes from the same source as the +5v on the ATX connector. Same with all of the other voltages. Some power supplies may have seperate +12v lines split between motherboard/GFX and molexes, but even then, the argument makes no sense. It's the equivalent of saying Molex splitters will reduce your power supply's efficiency (not to say that you couldn't make that happen by putting something that drew a hell of a lot of power though...).
You got a link for that type pf adaptor? Ones I've seen have been the type for a new 24-pin psu to an old 20-pin board like this one. found one. Unless your board really, really needs the extra power lines, an adaptor's a lot cheaper than a new psu.
Here's what i think goes without problems if you have a 20 pins psu and a 24 pin board this link bottom of the page there's 20 to 24 and vice versa. I mean why would they sell adapters if they were to do problems to the system I with you whypick1 on the fact that power start's up on the PCB and all the 5V or 12V are but a big blob of solder (for each voltage), so which is the real source, his idea would assume that every 2nd and 3rd molex on a 4 pin molex wire would be less and less reliable as you go down cause of the split? I really think this guy is in fact splitting hairs Quote cpemma:"an adaptor's a lot cheaper than a new psu. that's what i told him but he gave me the argument of the adapter
The adapter won't be junk, it's not ideal (possible slight voltage drop and heat generation under heavy loads) but it's not likely to cause any problems. On the plus side, once your done with it, youve got a handy connector to break-out old PSU supplys to play with
