I mean like the power connector cables. All power supplys have the same cables to supply power from the PSU to components right?
Hi switch mode power supplies come with such a variety of different connectors these days and you would want enough to connect all the components in the computer with enough power to drive them all which in some cases might mean a larger power supply that what you have in mind.
no all smps don't have same cable you have to purchase same smps as you using right now or according to your motherboard
not all PSUs have the same cables but they do all come with the same standard connectors. for example all PSUs regardless of wattage and brand will have the 4 pin molex conectors but not all will have the 6 pin and the 8 pin PCIe connectors and the higher end models will also come with 2 CPU 4 pin power connectors. which PSU you get depends on wattage demand of your system, amperage demand if you have a video card requireing extra power and the number of molex/sata power cables and PCIe 6/8 pin connectors you need.
