Hi

I just brought a new graphics card and a PSU (Corsair TX850). Everything my old PSU was connected to now has my new PSU, except for one 4-pin white box on the top right hand of my motherboard (Biostar TH55B HD) as my new PSU does not come with a 4-pin cable.

My motherboard can be seen here: http://www.biostar-usa.com/upload/Motherboard/b20100111.jpg

Not sure what that 4-pin connector is for, all it says above it is ''Power Indicator'' and below it ''ATXPWR2''.

So was just wondering if it is necessary to have the right connector connected to it before I turn on my PC.

Thanks

What does the Corsair TX850 manual say ? Is there a 8pin split connector coming out of the PSU ?

That connector supplies power to the voltage regulators, which in turn supply power to the CPU. So, it is very important that this is connected. From your PSU specs, I note that it doesn't have a 4-pin connector, but it does have an 8-pin arranged as 4+4. You need to plug one of these (whichever one fits) into this socket.
