Molex to 4pin is it a bad idea?

30 minutes ago, 662mann said:

I have a power supply with 1x4pin but the mother bored I’m getting has a 8pin power socket.

so I was not sure if the 2200g will need the 8pin or just a 4pin and if it need 8pin can i use a molex to 4pin adaptor to do the job with my 4pin So i have a 8pin.

 

I mean in theory you could do it. I'm not a professional and I like to test my luck with things though. You'd have to be splitting the yellow 12v molex power pin (Y-cable) to the top two power pins and use both ground pins on the bottom for a total of 4 pins. The 5v pin won't be used from the molex. Only try this if you're desperate or really lazy and okay will blowing something up if it doesn't go right. Try at your own risk. Not my responsibility.

 

edit: or you could buy an evga 600W with 80+ certification. it's like the cheapest actually good PSU with 8pin cpu and x2 8pin for GPU. (just bought one and I think its cool I'm not afiliated with evga LOL XD)

Yes it's not a good idea. Basically if your psu doesn't have the plugs to power the pc that means it's in need of a replacement :p. What psu do you have?

These days, it's simply best to buy an adequate, modern power supply that has the proper connectors.  All power adapters should be avoided in this day and age.  That includes the molex to PCIE adapters you get in some reference video card boxes also.
