Enough power?

post #1 of 3
Thread Starter 
I'm looking to buy a Kepler card, be it a 670 or 680. Thing is; I'm using a Seasonic 460w Fanless Power Supply and I'd like to keep it that way.
Hoping that I can squeeze in a 680, but I'll leave that for the PSU Experts to decide.

I'm currently running;

1x Stock i7 2600
1x Stock GT430
4x RAM @ 1.65v
1x SSD
1x HDD
1x Corsair H60 Liquid Cooler

As you can imagine it wouldn't draw much power and is consequently pretty quiet.

Do you think I'd have enough juice in the PSU to safely run a 680?

Run it? Yes. Safely? Questionable.

Btw since you have a non (k) cpu I'd recommend you go with a 670 over a 680.

The 680 draws approx 190w of power on it's own ... manufacturers recommend a 550w with 34 amps on the 12v rail ...

I would personally recommend a decent 650w psu ... rather leave a little headroom for future upgrades and also the less u draw from the psu the better lifespan it will have ...

ie: drawing 400W constantly off a 500w unit will put it under a lot of strain where as 400W off a 650w would be a breeze meaning less heat and less noise ass well
