Sometimes when people buy a computer power supply unit (PSU), there are several components in the box: a AC power cable to connect the power supply to the wall mains outlet, the power supply itself (PSU) that converts mains power into more useful forms of power, and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer. (On a modular power supply unit, those cables can be detached from the PSU). A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component. Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.
Modular power supplies are generally far better then a non-modular, but there are a few drawbacks. Pros. Getting rid of the spaghetti kludge of cables coming of the back of older power supplies, many of which you may never use. Only using the cables one needs reduces clutter and cleans up air flow inside a system which allows it to run cooler. Modular power supplies are usually of a better quality and there for more reliable. NOT ALWAYS, check. Cons. I suppose a connection of cable rather then a straight path could increase resistance on the line and therefor cause more heat or a poorer electrical connection. Loss of cables could be a major issue. Likely costly or difficult to replace.
replace it and see if it corrects the problem...
