thanks for that adapter tip. But my main concern is that will it be sufficient enough. Few years ago a 6-pin Pci-e adapter didn't worked out too well for me.

Thanks for reply.

ps: if its 12v either way (4-pin VS 8 pin) then why bother with the 8pin in the 1st place. Its the same voltage afterall.

Probably to provide more contact area at the connector as the currents involved are quite high. Besides connector contacts may get oxidized with time and effects of constant heat and cooling cycles inside the case have adverse effects on the contacts. More contacts the better...

It is the total amount of current(wattage) that the wires can deliver, some sytems, especially those used for overclocking, require additional power.

For safety, they underrate the wires that are used in power supplies and often use more then is needed. Thicker wires, or doubling up, allows those same wires to deliver more power. As long as enough are used you can deliver as much as the supply can provide.

Modern computers use almost exclusively 12V and rely on internal voltage regulation to run things like the chip, ram, and controllers at their respective voltages, these days rather low like 1.3 volts.

Modern supplies offer very little in terms of 5V, 3.3V and -12V, but some supplies offer as much as 120 Amps on 12 volts. That is 1440W!

Bronze, Silver, Gold, Platinum are all efficiency ratings. Power supplies 'waste' energy as they convert AC to DC power. 80Plus certifies that under certain load conditions the power supply is guaranteed to convert 80% of the power input to output. With the 20% being dissipated as waste heat.

Those two supplies differ in the base design. A single rail system puts out all voltage and current at one point. Split rail or multi-rail supplies will offer a total output power but split into two or more groups. As each rail in that RS model puts out about 250W that covers almost every current video card, and the other rail can serve to power the board and peripherals.

The GX supply is probably the better pick. Single rail designs are less troublesome and you don't have to worry about how much power you are putting on each rail.

okay thanks and finally here is the thing.
,
You already know my mobo
and here is my powersupply.

coolermaster 600w

+3.3v=25A
+5V=30A
+12V=18A
+12V=18A

I am gonna power up
i3 3220
HD 7770
2x4GB ram (going to upgrade to 16 later)
2x250GB hard drives. (gonna upgrade one of the drive to 1tb).


Should i be worried???

and get the GX PSU???

Thanks for all your help.
