When you overclocking your cpu you need more power to go higher...so how do you know if the PSU is enough?

I want to upgrade from E6600 to q9550 and overclock it ..so should I replace my PSU with another one? or 700 is enough to do 3.8 on q9550+overclock 4870??

I would change it, I havent even heard of epsilon

I think 700 should be plenty, though I've never heard of Epsilon PSUs, maybe other members can help you with that.

Anyhow, get the quad and see how it fares. If the PSU is a bottleneck it will bend under pressure so to speak: the +12V rails won't be @12V, they will go to like 11.8V or 11.6, below 11.6 the mobo is unlikely to start. However this is unlikely, and at least at stock you'll be able to monitor the +12V voltages while stress-testing the CPU.

thank you for this information

With just a Q9550 and a 4870, 700W is plenty.

You should have no problems.

still the psu can suck...

my friend had a chieftec 850w, and it didnt oc his q6600 to more than 2.7ghz, then I got him to buy a Thermaltake Thoughpower 850w, boom 3.6ghz! And the chieftec didnt run his 8800gts sli to btw..

True.. But on a generalization based on his hardware, I assume 700W (and the 12v rails) is enough. Whether or not the PSU is reliable in supplying steady power is a different story.

If it was a good brand yes, but to the op, try with the psu you have now and see how it goes, then change if it is bad

I Will try

Make sure to get a good brand like go4life suggested. Amperage and quality play the most important role. In my opinion a good 650 - 700w would power your system just fine.
Something like: CORSAIR CMPSU-650TX 650W
or CORSAIR CMPSU-750TX 750W. Goodluck!
