Is 600W enough?

post #1 of 11
Thread Starter 
Currently, I've got a Phenom II X4 955 @ 3.93GHz and a GTX 460 @ 880/1760/2100 on a 600W Kingwin PSU. Would I be able to add another GTX 460 or would that push my power usage over what the PSU can handle?

I'm running this PSU: http://www.newegg.com/Product/Produc...82E16817121012.

scroll down they recommend "You need a 650 ~700" for sli.

You might be able to get away with the sli if you dont overclock the cpu.

It should work. You don't have the greatest unit in the world but its 456W output at 12V should be OK for you what you're planning.

Alright, cool. It's just I'd prefer not to spend ~$100 on a new PSU. Thing is, I'd overclock both the GTX 460's pretty high, I'm just afraid of pushing the PSU too hard...

You probably won't want to overclock too much without a different PSU.
Note you could get an XFX 650W or Antec TruePower New TP-650 for $60-70, both of which would be more than enough for that setup without spending $100.

For typical usage, gtx460 draws about 160w. That quad may take up to 180w depending on speed and voltage. That 600w can do 38a/456w on 12v so it should work based on what you have.

Alright, thanks Would that be with or without my current overclocks?

It should be fine even OC.


My bad. I didn't read the op carefully. It can't do gtx460 sli with quad and 2x gtx460 OC especially at bench. It should be fine if quad and gtx460 sli at stock but it is on edge.
