I got a Ultra X-Finity 600W Power Supply and I'm concerned whether or not the 4870 will run its best with this power supply.

It should run no problems....500w is just about ok (min specs according to ati)....550 upwards and you are fine....that is unless you have 20 hdds or something.

I don't really like that brand too much but 600W is more than enough for 1 of any video card.

A full system with a Radeon 4870 on load will consume about 280 to 300 watt. Needless to say, a 600w power supply will run it without any problems.

i agree with theblackbird. You'd probably be able to crossfire two 4870's with 600w with no problems...

Just calculate the watts / volts = Amp ... so if u need 350 watts when is overclocked (just an example) divide that amount between 12 (volts that the rail needs to power the videocard) and presto = 30 Amp neede aprox by videocard so u can mix 2 cables x 18 Amp (12 v1 + 12 v2) ...etc

In crossfire double this need upto 60 amp aprox ... some PSU have 12v1 + 12v2 + 12v3 + 12v4 ... just see how much amps is given each 12v rail ...

I hope this help u ... remember Watts/Volts = Amp ...

The videocards always use the 12v rail ...the 3v and 5v rails are for the other components...
