4 pin or 8 pin connector

4PINs connectors are fine. Some motherboard manufacturer provide 8PINs claiming it can supply more power for overclocking. But I have seen many overclockers achieving better OC than I do using 4PIN montherboards vs. my 8PIN motherboard.

So I guess it still depends on the CPU itself, the skills of the OC'er himself + many other factors. Of course having 8PIN is better than 4PIN to cover all bases but I don't think you have to sacrifice your other preferences just for the sake of it.

thanks guys

The 8 pin EPS connector was added to the ATX 2.0 spec for high end desktops to low end servers. It had a lot to do with the fact that the Intel (the author of the ATX spec) at the time had super power hungry chips in the Extreme Edition pentiums.

Its a good Idea to have a 8 pin for heavy power draw but I have seen 250+ watts (which is a lot) drawn off a 4 pin with no problem of consequence.

In your case, overclocking a X4 620 you will be fine. You wont draw enough with that chip to worry about it.

Instead of making a new thread I'll post here:

Can the same be said for this board http://www.newegg.com/Product/Product.aspx?Item=N82E168... if I'm plan to use a 1090t and OC it later to 4.0Ghz. Thanks.

A 4 pin 12v power connector and an 8 pin 12v power connector from the PSU provide the exact 12v power source from that PSU. An 8 pin 12v power connector does not supply more 12v power...like 13v. The extra wires are there to create a better ground, nothing more. On a power supply, every lead is 12v except the 24 pin which supplies any other voltages which may be required by the MB.

Personally I would prefer something with 8 pin power and heatsinks on the MOSFETS for 4 Ghz overclock as that chip will top 200 watts at 4ghz and 1.5 volts. That said, it is a good board and should hold up just fine.
