Looking for some advice on PSU.

post #1 of 5
Thread Starter 
Hey all,

Made a few changes to my system recently and I am a little curious if my current PSU is sufficient or if I am on my way to some trouble down the line very soon.

My system setup below is most up to date, only thing not listed is a D-Link Xtreme N PCI Express Desktop Adapter.

I have heard that a decent 600W PSU should be sufficient for SLI 8800GTs but I am just a little curious if I am pushing it as is.

Also, I have not overclocked at all yet, but intend to in the future. I just need to get my act together and invest in some active cooling for the NB/SB for the motherboard. I am guessing that when I overclock I might outgrow the PSU at that point?

Anyways, thanks in advance for the advice. I figured that getting the input of knowledgable individuals from this board would be well worth the effort before playing the expensive guessing game myself.

What is your CPU overclock?

I'm running 2 3870 in Crossfire with a 600W, and I have no problems...

I think you're safe.

Many people have been pulled into the consumer mentality and they buy overkill PSU's. I would think that 600W would serve that setup just fine.

Rev1 >> No overclocking on it yet, but after I get my active cooling for NB/SB I plan on following the P5N32E-SLI overclock guide to give it a decent OC, not too crazy though, but just gotta see what I can get stable. I don't wanna push the heat too far on air as that will just affect the longevity especially with summer temps and such, but woul like to get the most bang for my buck I suppose.

How much of a difference will the OC have on the power usage you figure? Is there a general rule you can apply to figure how much extra power an OC will take?

Maytridy >> Thanks, I have been thinking that as well. It's not like I am trying to pinch my pennies, but might be a bit silly to get a huge PSU when the one I have is sufficient. I like it since it is quiet and no LED.

The StealthXstreams aren't my PSU of choice but they are still good for the most part and the 600 can handle your system no problem.
