20 pin connector on MB.

Recommended Posts

I currently have a 20 pin power connector on my motherboard. Does this mean that the card is an ATX 1.3 type?

 

If so, can I break away the 4 pins on HX520 24 pin connector and use this on my card?

 

Is it so that all cards wirh 24 pin connector is ATX 2.01 or higher?

Found this product information for my PC:

 

Mainboard:

Chipset Type: Intel 865G

Data Bus Speed: 800 MHz

 

Power:

Device Type: Power supply

 

Voltage Required: AC 120/230 V ( 50/60 Hz )

Power Provided: 230 Watt

 

Does this help?

It is atx, but is it ATX 1.x or ATX 2.0.

 

The question is:

If I buy HX520 and remove the 4 pins from the 20+4 connector, is HX520 compatible with 20 pin ATX 1.x system board then?

 

Other brands claim so, like this one:

Is it so that 20 pin connectors is ATX 1.x and 24 pin connector is ATX 2.x?

Will any PSU with a 20+4 connector work on 20 pin ATX-board when the 4 extras is removed?

atx 1.0 20 pin and atx 2.0 24 pin are the SAME just the 4 pins added more rails. So remove the extra 4 pins and it will work. Running a 20 pin psu in a 24 pin mobo now that IS pushing it. See that burn so many boards up from underpowering then the blaim the mobo co. hahaha LOL.

The ATX 2.0 spec also eliminated the -5v rail, among some other things, so the difference is not solely the number of pins on the main ATX connector. If your system is designed to function with the -5v rail, then there may be a compatibility issue when using an ATX 2.0 or later PSU, and this is why we can not guarantee that our PSUs would be compatible with an ATX1.3 system. Our PSUs will work with many ATX1.3 boards, but not all of them.

Also, and this is VERY important. The atx 1.0 provided ALOT of power on the +5 rail. The cpu etc ran off the 5v. NOW the atx 2.0 and EPS12v types the cpu runs off the 12v rail. SO, this means a atx 2.0 even if its say 400 watts can possibly not provide enough power on the +5 for a older atx 1.0 spec mobo. Ive seen them burn the pin brown, to melting the socket on the mobo from that. There are psus that still supply plenty on the +5 and have -5 rails you just have to look around.

 

just google "atx 1.0 psu" for one of the other co's psus. If you need help finding a atx 1.x psu let me know Ill get you alink to a store with one.

 

very few boards used the -5 so you might want to check the mobo specs. Also if a psu claims to be 100% backward compat to atx 1.0 it should be ok, since they beef up the +5v rail for that reason. (My psu listed in my specs runs atx 1.0 and 2.0)
