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

post #1 of 37
Thread Starter 
I just picked up this Corsair for $18 because I wanted to use old parts I had to piece together a whole spare PC. After some digging, I'm getting mixed answers.

Will this be enough to power this setup?

Asus M4A79XTD EVO AM3 mobo
Phenom II X4 965 BE
8gb (4x2gb) 1.65V DDR3 1600

One concern is that the PSU only has one 6-pin PCI-E, and the 560ti requires 2. Would a molex to 6 pin be safe? Would this be enough for this system at stock clocks? I don't plan to OC this rig, and was hoping for greater than HD5770 performance.

The Phenom II X4 965 BE pulls about 210W-230W from the PSU at stock under full Prime95 load.

The 560 Ti pulls about 280W-300W under full gaming load at stock.

You'll need a bigger power supply I'm afraid, a good quality 550W will be adequate.
If you did use it, using a molex to 6-pin would be perfectly fine smile.gif

Even though the peak power on the CX430 is just over 500W you'll need a bigger power supply I'm afraid.

Hey thanks for the quick reply! Would you say a HD6850 would work in the 560's place?

Going based on the calculator here, I believe that you could squeeze those components onto the power supply. Overclocking might be a no, however. http://extreme.outervision.com/PSUEngine

With no OC, Phenom II X4 965 should be more in the range of 125W and the GTX 560 Ti under 200W (probably more like 150W in games, or even a bit less on average and not looking at the peaks).

CX430 should be enough, especially current-rev CX430. Yes, molex adapters work... unless they fall apart physically (get unplugged, get loose, etc.), which is rare but happens.

Sorry, my bad.

The 560 Ti actually consumes 100W less than I stated, it's about 180W-200W. I thought the original numbers were a bit too high haha.

You 'should' be okay with the CX430 but only just, I definitely wouldn't consider overclocking at all.

thinking.gif This is what I mean by mixed answers, lol! Thanks for the help gents. I'd love to hear 3rd opinions on this.

Also, no one has answered, but will a molex to 6 pin be safe? I've seen a couple of threads about them catching fire...

Thanks for the clarification! This rig will be a spare/guest PC at most. I can get a 560Ti for $70, so why not eh?

I'm about to sell my old 560 Ti to a friend, such an awesome card thumb.gif

It's perfectly safe. Just make sure it's a dual molex to single 6-pin connector, whoever thought a single molex adapter was a good idea should be hung.

I'd do it. It would be getting to that 80% capacity, but I'm sure it'll work. If it doesn't, it'll just shut off on you, and then you know you need a bigger PSU.
