Power connector confusion

[Kikikan]

Hello everyone,

I currently have a PSU with 20+4 pins. My new motherboard will be 24+4 pins.

I am a little confused with these power supply things. Are they compatible?

There are no 28 pin connectors . I am sure your connector is actually just a 20+4.
The connectors come in 20, and 24 pin, the 20 pin are older ones, the new 24 pin +4 is there for extra power and another phase for the CPU.

THE PSU may have a 28 pin connector
"There are a total of 28-pins where the cable plugs into the PSU's modular interface, instead of the usual 24-pins. The extra four pins are "sense wires". While a +3.3V sense is part of the ATX standard and is found on most PSUs, it is not often implemented. The RMi not only utilizes the +3.3V sense on the ATX connector, but also utilizes an additional +12V sense and +5V sense. These sense wires read the voltages at the load (the end of the cable) and can increase voltage automatically if voltages drop" -Blackbird

What is the make and model of the motherboard?

The new MoBo is going to be an MSI B85M-G43.
The main connector has 24 pins, and there is a 4-pin 12V CPU power connector. Will I be able to give the CPU power?

Sorry for not clearing that out, the MoBo has got 24 pins, and a 4-pin CPU power connector. My question is that how can I wire the CPU with a 20+4 pin PSU, if all of the PSU's 24 pins will go to the main connector.

Yes, every computer has a seperate 4 pin CPU power, most newer gaming boards have an 8PIN cpu power slot, this is completely seperate from your 24 pin power.

Looked up your board, You can power it no problem, Just a normal 24 pin, or 20+4 and a 4 pin CPU connector, sometimes the PSU may only have a 8 pin cpu connector, you can just use half of it with no problem.

Every PSU comes with a SEPARATE 24 pin and SEPARATE 4/8 pin CPU connector.

Not an idiot, PSU connectors can be tricky to the inexperienced. now you know
If you have any other issues, don't hesitate to ask Toms!
