Posted 10 April - AM. Minimum Posted 11 April - AM. Thanks Toolman!! That info is very helpful. I regularly get old boxes that folks from my church bring me because they are having problems.

I never thought about checking the connectors-that will be on my SOP list from now on. If there are no responses to my post for 3 days I remove it from my answer list. If you wish to continue the thread after 3 days please PM me.

Side thought: that is really sad that manufacturers do this ; another reason I only build my own. Manufactures don't care if the consumer has to buy a 24 pin power supply just to add a PCIE graphics card. And yes I also prefer the building of my own computers so I don't get it stuck to me by an oem manufacturer. Community Forum Software by IP.

Since I'm having troubles with my motherboard, which has 24 pins, I tried to connect only the first 20 and the system booted up fine. I'm curious: can any ATX motherboard run with pins power? Will I simply experience lower performance? Since I've got direct PSU connection on my graphic cards I believe I can run on 20 pins fine, especially if this ceases computer failures.
