so i recently had to replace an aging power supply in my parents computer which uses a graphics card with 2 x 6pin pci-e. so no problem. i end up going with an MSI MPG A850GS which is ATX 3.1 and both 80 plus Gold and Cybenetics Gold. reviews and specs here: Hardware Busters & Cybenetics
but then as i'm looking at it while installing i notice what you can clearly see in the picture. now i'm not sure if the new ATX 3.1 spec has anything to do with the connectors and they are interchangeble between brands but if this IS the standard, i can clearly see why so many people have had problems. you can clearly see that the posts for the 12v 2x6 (revised HiPwr) are clearly HALF THE SIZE of the standard ones we've been using for years! so a little background, i'm an electrician of 30yrs, why in the Funk would they use smaller posts and push more power through them? it's no wonder there are problems, those posts look to be around 22 awg(?) wire and they're steel, not copper, but the bigger problem is that little post has probably HALF the surface area of the bigger ones, now being steel doesn't add a whole lot of resistance, but the small diameter and contact area SURE DOES! especially when pushing twice the current! you get what's called thermal runaway. because the more resistance there is, the more heat is produced, which more heat in turn, adds more resistance which adds more heat until FINALLY you get melt down. man whoever designed this spec should be dragged behind the shed and shot. and that's the new standard? what happened to UL certification and whatever the Canadian equivalent is? did ANYONE test it or is everyone buying into the newest ATX standard a working beta tester?
so this is my call to anyone with a brain. buy cards with standard pci-e connectors. save yourself a future head ache and do the world a favor by making 12vHiPwr go the way of the dodo.
