Discussing ATX power issues, is it enough?
Okay I just want to get a little talk, instead of building someone a PC
I think the ATX form factor power wise (and heat wise, but that's where BTX steps in) is vastly inaqquadarate. Specifications have stated that their is a maximum of 6 AMPS travelling thru a wire.
For a modern PC, they cannot supply enough power.
ATX 1.X version connector
3.3 Volt = 3 x 6 Amps = 18 Amps x 3.3 = 60 WATTS total
5 volt = 4 x 6 Amps = 24 Amps x 5 = 120 WATTS total
12 Volt = 2 x 6 Amps = 12 Amps x 12 = 144 WATTS
12 Volt 4 pin = 2 x 6 Amps = 12 Amps x 12 = 144 WATTS
Ok, we are by far bypassing what our Motherboard's are allowed to take in. This is causing the lead's to heat up. In a recent power supply test, they were pulling 3 times the power that allowed from the connectors causing them to heat up (And i believe resistance increases)
That power is not enough, expisally since we usually pull our power off one connector, used to be 5 volt but now we are using the 12 volt.
