I am looking at getting a Gigabyte m55plus s3g motherboard. http://www.newegg.com/Product/Product.asp?Item=N82E16813128010 I already own an Aspire 500w Power supply. I bought it a few years back but never used it. It has a 20 pin connector. http://www.newegg.com/Product/Product.asp?Item=N82E16817148005 I think this link is still the exact power supply I bought a few years back. Will I be able to use this psu with the new motherboard?
the picture of the boatd shows a 20 pin plus a 4 pin which your psu has but the text on the 20 pin motherboard connector says 24 which i think is a typo error. so go for it
Here is a link to the PDF Manual. http://america.giga-byte.com/FileList/Manual/motherboard_manual_m55plus_s3g_e.pdf Page 7 shows the board and it shows 24 pin. Now from page 19 of manual. So even though this is a 24 pin motherboard I should be able to use a 20 pin psu?
