Corsair 620W enough?

[INGlewood78]

The 620 is powering the following components:

i7 920 @ 4.2 @ 1.4v
DDR3 @ 1.6
5870 o/c to 900/1250
1 DVD drive
1 Hdd
1 D5 pump
5 fans in total

I've been getting some cpu instability and was wondering if I needed more juice.

That's more than enough. I'd blame the instability on the overclock, not the PSU.

Ya it can't be your power supply unless it's unstable at stock too. And your psu could probably handle at least 150+ watts more easily.

Thanks all, I wasn't sure if pumping more juice into my CPU for the overclock was over-extending my psu.
