Dual 4 Pin adapter?

[chevmaro]

I heard the P35 boards use two 4 Pin adapters is this true? My power supply only has one 4 pin. So is there an adapter I can buy so I dont need to buy a new psu? If so can you link one? Will this one work? I found it at newegg.

i only have 1 x 4pin attached to my MB and i've got my CPU Oc'd from 2.4 to 3.55

Just plug it in without any adapter. If it doesn't work, your board has a design flaw and you should buy an adapter. Preferably at a brick and mortar store, so you don't get hammered by shipping.

Alright thanks guys. Ill be buying my new PSU I just need this one to last me 2-3 months.

I agree. My Abit IP35-E has a 8-pin connector but IIRC the manual states that it can run on a single 4-pin connector.

I read the online manual for the abit board. And everyone I ask says it can be run with the 4 pin. The manual even says so. But what I dont understand is why it has a 8 pin when 4 pin works just fine. And nobody seems to know what the difference will be from using a 4 pin VS. an 8 pin. Kind of stupid.

I think the 8-pin is for the "just in case".

Look at the foils on the board by the connector. They are probably
just doubled up Pin 1 to Pin 1 ... etc ... for extra current capacity
So unless you install a whole bunch of high power extras, you
should be ok. Also in most cases, items that need high power
will have their own power connector on it. On another thought
the idea might have been two 4 pin power plugs side by side
so that the power plugs into one and then, say, the video card
plugs into the other for power.

Having additional conductors from the supply to the board (8 instead of 4) means the effective resistance is reduced (in this case, cut in half), which in turn means less voltage drop and less waste power. If the current being delivered is large, doubling up on wires also helps ensure that you don't inadvertently create a fire hazard.

The new connector was introduced for servers, especially multi-processor servers, which need to draw a fair amount of current through this connector. From there it found its way into consumer parts, right around the time consumer CPUs' power demands fell dramatically.
