Sorry if this is a n00b question, I've been out of the "updating" game for a while and the new video cards and their power requirements well I'm pretty much out of the loop.

I'm planning to upgrade and heres what I am intending to get

Mobo: eVGA X58 SLI
CPU: i7 930
CPU Fan: Corsair H50
Video: Dual 460 GTX 1GB

This is pretty much what I will build around the other components are kind of up in the air. My old components that I think I can scrap are far and few between but I think can salvage my case and MAYBE PSU?

PSU: COOLER MASTER eXtreme Power RP-600-PCAR 600W ATX from factor 12V V2.01 Power Supply

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It says that its SLI ready, but its old and someone told me i would need at least 900W PSU to run it, and others have said it might be okay. I just need a firm answer been reading the forums and pretty much the people here are the smartest =P Thanks in advance, once again, sorry i'm a n00b =/

900W is just too much, that will run 2 GTX470s with ease.

The GTX460 isn't as power hungry as the original Fermis, but still consumes 110W each on load. Your CPU consumes ~130W, then 10W for fans, and another 10W for the HDD/Mobo/Ram.

110+110+130+10+10=370W load on the 12v rail.

You PSU has ~400W on the 12v rail, so it you should be fine, but it will be cutting it close. Remember running a PSU near full load isnt good and its life will be shortened.

One thing to consider, what are the clocks of that i7? If its a high OC, Id say you get a better PSU (Seasonic 620W/Corsair HX-650 and such) for the sake of system stability.

So lets say im curious and want to see if my PSU has enough juice. What happens if i were to run it with everything plugged in, is there any "risk" to the other parts or only to the PSU or maybe no risk at all?

I don't want to pay for a new PSU persay yet, if i need to i will but i'm trying to salvage some components. I dont know how much i will overclock the CPU yet, I'm sort of new to the whole overclocking CPUs also, i guess somewhere around 3.6 to 4ghz? I've only used RivaTuner for my videocards in the past. Thanks for the quick response though! I like that i MIGHT be capable of running this.

here's a review of the cooler master extreme power plus 600w

"Why manufacturers like Cooler Master are still carrying power supplies with fake wattages is a mystery to us. We know that this is a very low-end power supply, but this doesn’t give the manufacturer the right to lie. This unit should be labeled as a 450 W unit and sold for half of its price. Being labeled as a 600 W product and sold for USD 70, it is a complete rip-off.

If you pull more than 450 W from this product it will offer real risk to your computer, plus it presents a lousy efficiency between 69.2% and 77.6%."

Granted that is the extreme power "plus" but I would invest in a better PSU

This is what happens, something has to give.

Well that effectively changed my mind haha.

SO What do you guys recommend getting for these two video cards?

Though the Cooler-master has overload protection, which hopefully, if works, will just shut off the PSU when its running out.

Agreed with above... If you go for 'cheaper' power supply get at least 200watts over what you need. If you see a bunch of 700watters for $100 bucks, then theres one for $40 in the same category, you can bet its most likely junk

So the one that was recommended was only 650W only 50W more than my "600W" I know the earlier post said that reviewed to only have 400W or so.

Is the 650W enough? i am digging the green though btw!

200W over what i need...so is that around the 700W? do they have 800W?

A good quality 600w - 650w is all you will need, Guru3D's rig only pulled 433w with a pair of 460's in it.

there is no industry regulation on power statements. so you can grab a 350w PSU off the shelf, stick a 500w sticker on it and sell it as such...in fact a lot of these companies do just that. The only way to find out about actual performance is through independent reviews.

That xfx is an excellent PSU and if you like the green, all the better. It has 650w of efficient continuous power and can peak at a much higher level when needed. Its made by seasonic who make some of the best PSU out there including some for antec, corsair, pc power & cooling, and those sold under their own name.

3dguru test was only stressing the gpu's so you need to add 100w for cpu if not overclocking I would go for a 650w on 12v rail, if over clocking needs extra 150w to 200w i would go for 750w on 12v rail. That wood leave 100w for extra devices.

Alright so i think i made my choice! I love the lime green and yeah i think i'm going to go for the extra 750W and i've been reading reviews all day for the XFX 750W so I think i'm gonna jump on that just incase i need that extra power!

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Good choice?! Hope so, next step is determining which brand of 460GTX to get =/ why are there so many options for everything!

Most likely they are made by the same company (Seasonic) as well, though Corsair do source from CWT also.

Congrats on the new PSU!
