i have a ASUS M4A87TD-USB3 mobo and a Corsair 550 Watts Power Supply. Ive looked in the manual andit says you need to connect the one that ive connected and a 4 pin. It says that if you dont connect the 4 pin the computer wont boot! is there a way around this or it f**ked?
Before purchasing a power supply you should always first check to see if it is compatible with your motherboard in the following two aspects: 1) Does it provide enough power for the motherboard 2) Does it have the appropriate connectors for my motherboard. There are also issues with certain high performance processors requiring very clean or high regulated power supplies (i.e. very little ripple, etc). As long as the power supply offers the voltages you need on one of the connecters, there is probably some sort of adaptor you can purchase... or you could hack something together. But, again, the power supply may have intentionally left off the connector you need because it does not fulfill the strict electrical specifications required by your motherboard. In other words, if you don't know what you are doing, it is probably best to just purchase the correct power supply for your hardware. Forcefully adapting an inappropriate power supply into your machine may later result in unstable system performance.
Just replace the power supply. What's the problem? You have an OLD ATX powersupply with 20-pins. The NEWER ATX power supply is 20+4 pins. --- Kasey C, PC guru since Apple II days Make it idiot proof and someone will make a better idiot.
