ATX12V on Motherboard

April 30, 2009 at 22:17:49
Specs: Windows XP
While comparing an older computer to another, I noticed my AN7 board didn't have anything hooked up to the ATX12V1 connector.

I haven't noticed any problems so far. I don't even see a connector for it coming out of the PSU.

If it matters, the CPU being used is a Sempron 2600 1.83 GHz. The PSU is 250W. The video card being used is only a GeForce FX 5200.

Does this computer need another PSU?

Well it depends on the number of pins of the board if ti's 20 pins then a simple ATX power supply would be enough how ever try some other comments about it. I'm not that good at power supplies.

A lot of socket A boards run fine without the 4-pin 12V plugged in; many of them didn't even have an ATX12v plug!

However, a PSU that isn't ATX12V-compliant is probably an old, crappy thing that should be replaced anyway. What's the amperage on the +12v rail?

If I'm reading it right, it looks like it has 13.0A on the +12V rail. I'm sure that's low, but how many amps should there be for a board this old?
