I am searching online for new a PSU but none clearly display the leads that come with them.  So the result is that I have ordered several 850W units only to find none of them have a lead for the square 4 pin 12V ATX socket. Without this socket being connected my computer will not boot up.

I cannot keep ordering power supplies and returning them, so I decided to come and see if anyone on here can suggest how I can overcome this problem.

Most suppliers should list this information, e.g  this one:-

http://www.ebuyer.com/630113-evga-supernova-850w-fully-modular-80-gold-power-supply-220-g2-0850-xr

 

scroll down past the reviews to the Technical Specifications where you will find:-

 

Power Output Connectors Details 1 x power 24 pin ATX ¦ 2 x power 8 pin EPS12V with detachable 4 pin ATX12V section ¦ 4 x 8 pin PCI Express power with detachable 2 pin section ¦ 2 x 6 pin PCI Express power ¦ 10 x 15 pin Serial ATA power ¦ 4 x 4 PIN internal power ¦ 1 x 4 PIN mini-power connector

 

If your suppliers are not providing this information then you need to change suppliers.

As you will see from this link, I have been looking in the wrong places. There is no technical Specifications shown on any of the power supplies I looked at on Amazon.

The one you have shown me though looks as if it will be ideal, so I am going to order it.

 

Thanks very much

Surprising you are having this problem as any ATX power supply from Pentium 4 days onwards (ATX12V) should have that 4 pin connector.  Many newer computers use an 8 pin connector, so power supplies are normally now supplied with a 4+4 plug which can be split for compatibility for motherboards with either 4 pin or 8 pin 12v connectors.

Just checked the power supply I am about to return and although it has some 8 pin connectors, they cannot be split. In fact I think they are just for plugging into the power supply itself. Lots of old fashioned 4 pin plugs though that are of no use whatsoever. The kind you used to plug into the old IDE hard drives.

To that PSU  - no. Not as good quality as you can get for close to same price.

 

Without knowing your machine specs and bits and pieces or what you are replacing I cannot grasp the problem completely.

 

Perhaps you are looking for an 'adapter' to hook up legacy items.
