I have a Sentey® Power Supply 725w Pc / Xpp725-ps.
One of it features is that it says it has a "Single 12v Rail" for the cpu.
I am confused as to why it can be called a Single Rail when it has two 4 pin connectors coming from one big cable. Are the two plugs combined make up the "Single Rail"??
I am raising this question because for a long time, I used only 1 of the power supplies 4 pin connectors even though the board I am using has an 8 pin socket. The reason for that is because one of the 4 pin plugs didn't seem to match entirely on the other half of the 8 pin socket so I didn't hook it up. Was I only using half of a single rail? I don't get it.
I recently bought some fancy cable extensions for my computer and I noticed the extension for the cpu rail had the right pin shapes on its plug and fit perfectly into my board. my power supply also fit perfectly into the extension. So for the first time, I had the full 8 pin socket hooked up and the machine ran with out a hitch. So... can some one explain this to me? why it worked with and with out both 4 pin connectors hooked up? I just want to understand.
I had two rx 480's at one point and I got a couple black outs when using demanding crossfire games. was it the low wattage of the power supply or was it because I only had 1 of the 4 pin's hooked up?
