I want to buy new psu for my graphics card and I noticed that my mobo dont have a 24pin connector, it has a 8pin only. What else can i use for this mobo to power up? the mobo is 8k0x7

As you can see, the #25 is the connector for the whole motherboard to power.

That is a very non standard motherboard.
What graphics card do you want to use?
Up to perhaps a GTX1050ti you might be able to power it on just pcie slot power.

While a standard ATX motherboard might have 8 pin power for the motherboard, I think it is the 24 pin connection that actually starts the psu.

I suspect you might do best to abandon this motherboard.
 


I already bought a GTX 1060 6gb to install in this mobo. btw do you think i can use molex to 8pin connector to power this up?
 
What are the dimensions of the psu that you have?
Is there a make/model on it?
In your kind of case, it will be a non standard psu that may not have an equal sixed replacement with adequate power for your mew motherboard.
A decent psu will have both a 4 and an 8 pin atx cpu power connector that you need.
The problem is that since the 24 pin psu motherboard connector has no place to plug into the motherboard, there is no way to get the power on signal from the motherboard to start up the psu.

I suppose you could permanently short pin 15(green) on the 24 pin connector with a ground to get the psu started.
You could then use the on/off switch on the back of the psu to turn it in or off.

If your case does not allow a standard ATX psu, you could place the psu on top.

My suggestion is to also buy a standard cheap case, 450w atx psu, and and motherboard for your processor

Have you measured the height of your new card? would it even fit in your case?
 


The #17 on the picture is a Front Power Switch Connector, so I can use the front power button to power on my mobo. Yes im going to buy a cheap case and an EVGA 500w 80+ White PSU for my unit. Do you think this psu is enough?

Ahmm, can i use a 4pin to 8pin connector to plug-in in the #25 on my mobo?
