Quick question on PSU, case, and mobo compatibility


Nov 6, 2010
Hi I just wanted to make sure that these three things would work together. I am building a gaming rig for my little brother but I am a little confused about how the case fans would connect.

PSU: Antec BP550 Plus 550W Continuous Power ATX12V V2.2 http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016

Case: Antec Three Hundred Illusion http://www.newegg.com/Product/Product.aspx?Item=N82E16811129066

Mobo: GIGABYTE GA-970A-UD3 http://www.newegg.com/Product/Product.aspx?Item=N82E16813128519

The question that's really bothering me right now is how the case fans on the Antec 300 will pair up with my mobo and PSU. I read in the reviews for the case that I need four 3-pin connectors or something like that for the fans in the front but I'm not sure if the PSU has that. I am a little confused on the connection of the case and mobo fans so if someone could clear that up for me that'd be great. But ya, please check if all these are compatible and if I will be fine with connecting all the fans or if I'll need some form of adapter. Thank you

2 x system fan headers (3 pin for your fans)
1 x power fan header (4 pin for your CPU cooler)

This is what that board has on it. Your case should come with adapters for the other 2 fans (molex 4 pin to 3 pin fan, with passthro) you can chain them together on the end of the power wire thats powers your HDD or whatever.
