I inherited my mom ' s collection last year . So much Carpenter ' s . <| sep |> And people wonder why it never looks the way it does in the picture <| sep |> Reality is Plastic by Anthony Jacquin <| sep |> I need to register rRomnia . <| sep |> All will perform the same given all other things equal so the main difference is your control over cables . With a nonmodular PSU , you have to have all of the cables , and are likely to only use like 60 of them , meaning if you want a clean build , you will have to route them and hide them away . With a fully modular PSU , you have complete control over all of the cables that you use . However , the main difference that i notice between a full and a semi modular PSU , is that you have the option to not use the 24 pin and some of the 468 pin cables . In 99 % of the builds , this is completely wasted . You will ALWAYS be using a 24 pin and a few 468 pins for your mobo and GPU . I have a fully modular PSU , and honestly its completely wasted . If i were to build a new rig , i would go for a Semi modular because you still get most of the benefits . You might have to route a cable or two , but you dont have the whole mess as you do with a nonmodular , and you dont pay the Fully modular premium .
