The SX38P2-Pro sports a 450w powe supply. I just bought one and can definately verify this. See http://www.newegg.com/Product/Product.aspx?Item=N82E16856101058 and check the specs. The manual also verifies this.
Has anyone here been able to use an aftermarket cooling solution (i.e. not ICE) on an sx38p2-pro? I've found that the holes in the motherboard are quite non-standard in configuration (see this picture). If anyone can help I'd appreciate any suggestions. I can't even mount my cpu waterblock...
