Power supply for a future Ivy Bridge build

[Vonje]

Now that Ivy Bridge is out, I am only waiting for NVIDIA to release a new Kepler GPU that directly succeeds the GTX 560 Ti. In addition to an i5 unlocked IB processor and a yet to be released video card, I am going to use an ASUS Z77 motherboard, one SSD plus at least two HDDs, three fans, and a PCI-E sound card I have lying around. With this said, I'd like to know what kind of power supply would fit beforehand. Corsair's TX750 is definitely what I would consider. This PSU is most efficient when 50% of its capacity is used. Since I have no idea how much power this rig would draw, I am asking you for recommendations.

If you get a PSU with about 40A on the +12V rail, you should have a lot of breathing room. Something like this

CORSAIR Builder Series CX600 V2 600W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply $70

I would stay away from the new CX-line, they are rated at 30C and you should be able to find a 80+ unit rated at 50C in the same price range without much trouble.

48A on the 12V rail, runs quiet, highly efficient, well built, and can live up to its specs.

$140 for a PSU that is overkill for a system like that? Oh well, that system will run just fine with lower rated PSUs.

He asked for recommendations, and did not specify a budget. However, if we're looking at the cheap end of the market:

Now you're getting more in line.

80+ bronze is adequate. Not more, not less. It's the wattage rating that I can't decide.

For reference, power consumption of a system with an overclocked IB i7:

Even if you add 200W for a GTX 680, all of the listed PSU's are going to be plenty, though you might find the CX600 running a little warmer and louder than you'd expect.

From what ive been reading Ivy Bridge isnt worth it unless you're looking at PCIE 3.0 functionality.

5-10% Performance over Sandy Bridge isnt worth the heat or the price difference imo.

I am not upgrading from Sandy Bridge.

I think yahoo was saying that SB is still a better option over IB and mother boards may be cheaper and there is more to choose from ATM..

I've always been told that Ivy Bridge would cost the same, and that heat issues only occur with remarkable overclocking.

It looks like Intel decided to use thermal paste instead of solder on the heat spreader side of the chip, and that's what's causing the heat issues with Ivy Bridge. Overclocking doesn't seem to be the trigger.

I'm undecided on ivy ATM... But I won't be changing from SB that would be silly unless I go Socket 2011 if i upgrade the wife's rig but at this stage I'm happy

On topic I think any Quality 650W psu would do the job for a single gpu setup..
