4-pin ATX to 8-pin EATX connector

[assasin]

my mobo Asus P5B Dlx has the newer 8-pin EATX connector but my new psu CoolerMaster Extreme Power Duo 650W has the old 4-pin ATX connector.so i made a 4-pin ATX to 8-pin EATX connector fro myself.i've seen pics of 4-pin molex to 8-pin EATX connector on the net but i havent seen any pics of 4-pin ATX to 8-pin EATX connector.
my pc is working after connecting this home made converter.
all i wud like to know is whether its safe to use a such a converter which draws power from the default 4-pin ATX connector of the psu and provides pwr to the 8-pin EATX connector on the mobo.

its surely safe , if the connector you made is nicelt soldered and insulated.. just check the joints and they should not be loose.. else everything is fine..

Can you pl provide details or reference to how to do it? I may need it in near future since my Antec SP500 has only the 4 pin Mobo connector.

its very easy to make one.all u will need is a bad psu(cuz will need to cut out the 8 pin block from the 24 pin mobo connector) or u can buy urself a 20-pin to 24-pin converter for 20 bucks(i' prefer the 2nd one cuz u can connect the 4-pin ATX connector to the 20-pin female jack).

all the yellow connectors in the 4-pin ATX connector r +12V and black r for COM/GRND.in the 8-pin connector all the top 4-pins r for +12v and the bottom 4-pin r for GRND..if u cant understand this 1st connect ur 4-pin ATX connector to the 8-pin EATX connector.see to which 2 holes correspond to +12v.the 2 holes adjacent to these +12v holes will also be +12v and the rest 4 for GRND.now map ur wires accordingly.

Thanks for the precise description and it seems quite easy. And I have 2 old 300W PSUs lying unused.
