Corsair CX430. Is it enough for 965BE + 560Ti? - Page 3

post #21 of 37
The CX430 would handle your planned build fine, even with an HD7970 in there instead of the 560Ti. 430w is more than enough for most single GPU computers.

I don't know if I would recommend that.

Factor in the only 80% rating, your looking at 344w usable watts if I did that right...You'd be cutting it close.

Power supplies are rated for DC output so if its rated for 430W then it can supply 430W (as long as its not junk which the CX430 isn't).

You don't need to do that calculation wink.gif

I think you're totally 100% fine... When gaming your machine should pull like 350w max.

I'll add my two cents.

You have 32amps to work with on the 12v rail of the CX430 which translates into 384 watts.

A gtx 560ti use 170w full load as per Nvidias site, so let's say 185 - 190w with overclocks. And a small overclock of a Phenom II 965 should use about 150w full gaming load, maybe less.

Rest of the system should use about 50w give or take, so the cx430 is pretty much perfect for this build. If there is problem with overclocking as in the system just shuts down during a game or something, then just run stock on your components.

But I think you'll be fine with some overclocking.smile.gif

And it's nice to see you around again pioneerisloud, it's been awhile!tongue.gif

Thanks for all the help everyone. I refused shipment and am getting a refund - even though 430W is enough to power these things, I'd feel much better about getting a PSU with more connections. Great info though - if I ever need to build a PC for my parents or something, this will be my go-to.

Feelings prevail over logic once again

I've used CX430 in this many builds -3 of them that never happened because my friends are using mid-range graphics cards just like you. 560 Ti, 5850, 6850, 670 (works fine), I'd even put in a 7950 in there, 7970 if there's no CPU overclocks and it ain't a beefy power hungry PII that'll be overclocked.


$20AR? Can't beat that

My concern is finding second hand GPU's. Finding a 6850 (the strongest single 6 pin gpu) has proven to be at least $80. $100+ on eBay. I found a 560Ti for $70, local. Before that, they were at Microcenter refurbished for $80. My logic is why limit myself to such a specific type of card where I'll end up paying more for substantially less performance? Everything runs off 2x 6/8-pins now, so my concern was hamstringing myself by saving a few bucks on a PSU.

So then use a molex adapter.
