Replacing PSU: Necessary to Replace Component Cables?

[kmo1326]

Hello,

I've been having some issues with my computer and I think I have the issue narrowed to either the power supply or the processor. I decided to start with the cheaper of the two and ordered a new power supply.

My question is: Do I need to replace the cords supplying power to the components or can I use the wires from the previous power supply? Obviously, I'd rather not have to rewire my computer unless I have to. I've posted information for both power supply units below (both are fully modular).

Additionally, I've come across a few similar posts that, like this one, ask about component specific issues. Is there a general rule of thumb for replacing power supply component cords? For instance, when replacing with a PSU by a different manufacturer, if it's over X years old, if there is a change in wattage, etc.

Thanks!

Always use the new cables a lot of the time the pin layout is not the same at the power supply.

That's a bummer. Thanks for the quick reply!
