Hey all. I am trying to verify some info. I have to go home and look at the maker and model of the power supply I have.. but this is a general question.. I bought a 300W ATX 2.0 Compatible Power supply the other day.. since it said Compatible. I pretty well assumed that meant you could use it for ATX as WELL as ATX 2.0.. I got home and found out that it only had the one connector for ATX 2.0.. I had read that ATX 2.0 connectors should still be able to be used to ATX it simply does not use the last 4 pins on the connector. BUT.. my connector on this ATX 2.0 PS has a tab sticking out on the back of the connector not allowing me to slip it into a regular ATX slot on the MB.. does anyone have any info on this. This may sound silly but can I just slice the tab off and try to use it. .. I am guessing that the answer is no. since it apparently is trying to prevent usage on regular ATX MB.. just looking for any help on this. Again I know I will need to get the model number etc and maybe try to get info on the makers website… just trying to get some general info till I get home to look at it. thanks a lot.

Hi, Not sure, but the ones I see at the Computer shows let you slide the extral 4 pin connector off the end of the 20 pin connector to use either way. An extra latch kinda says the 4 pin conn is removable.Yes you can remove the extra 4 pins latch. The extra pin are duplicates of pins in the 20 pin section. Kinda like using heavier wire and/or keeping Signals from mixing in the leads. Would be needed if you are running a power hungry Processor and/or wanted to OC. Hope this helps a bit, Jim

i will give it a shot. thanks.

You could also get a 24-pin to 20-pin adaptor. Check out the following link: ADPmods.com

Look closly at the 24 pin connector on your power supply. There is an area at one end that separates into a four pin connector . Unhook the 4 pin connector from the 24 pin connector. You should now have a 20 pin ATX connector. Disregard the extra 4 pin connector.

Some ATX 2.0 PSUs have a 24-pin plug & others have a 20+4-pin plug. The "+4" can be disconnected from the other 20-pins so that it can be used on an earlier ATX board. Do NOT cut anything! If you have a 24-pin plug & a 20-pin board, get an adapter like najitech suggested

Yes all of this stuff is true. And I was not so much concerned about the extra pins at the end. What bothered me is the tab on the back of the connector. This power supply didn’t come with a specific 20 pin connector. The back of the power connector has this tab sticking out. that looks to be preventing skipping that connector into a regular ATX slot. As if it needs a small gap in the back of the MB connector to accept this power connector. . My only concern was if I just snipped that tab off and then slid it into the power connector on the board could it cause damage. I mean I am sure there is a reason that tab was on the back. I still have been unable to get online to the manufacturer to see about this. .. thanks for the suggestions though I appreciate it.. but yes I am aware that normally I could just plug it in and not worry about the other 4 pins.. i may jsut go and look for that adapter as you were talking about.
