No, of course not. As it is, if the PSU is sucking in 40C air, that PC is pretty damn hot.

But I think it's a testimony to build quality if anything.

Ordered the Corsair this morning. :)

I was leaning towards the PC P&C based on name/rep alone but with current pricing (still slightly better even without the MIR) I couldn't justify spending more for a unit which appears to offer the same specs.

I'm going to jot down some temp #s to compare between vid and chipset temps with the 600W and the new 750W to see if there is much difference.

Got it installed this morning and was initially overjoyed at Core Temps, but then I noticed CPU-Z was reporting lower Core Voltage than my GameXstream did (after Vdroop). Quick prime test showed that the system was indeed unstable, so I suspect the Corsair unit is providing lower volts.

Not a big deal.... took an extra .02V in bios to bring it back up to where it was before and everything seems to be good to go,

It does make me wonder though what my actual delivered V were with the gameXstream, and how much the VRM on the motherboard was working to compensate.

The voltage should not affect your overclock unless it is REALLY low.

It was reporting 1.504 vice 1.520 and was indeed low enough to affect stability. It's been bumped up and everything is fine now.

I always go back to a stable OC after about a month or so and drop the V down to get the lowest possible for prime stable. Changing the PSU dropped it down enough (after Vdroop) that it was no longer prime stable.

I went from an Antec neopower which is at 480W to a CorsairTX at 650W. The old powersupply stopped to work and the warranty time had gone.

So far the CorsairTX has been working excellent without any problems. The sound from the powersupply is a bit higher than the Neopower but it's good. A very good piece of hardware, indeed! I was a bit sceptical at first to the Corsair brand when it comes to powersupplys but tests have proved it to be one good piece of hardware which is energy efficient too.

If one wants the very best I think, however, that the more expensive powersupplys from Seasonic is better. Tests have proven that they can utilize 88% in power efficiency which even the Corsair powersupplys can't reach. Seasonic S12 Energy Plus. Silentpcreview has articles on them.

Yeah, the S12 Energy Plus is a pretty amazing piece of kit but the highest wattage available is 650W....which is a shame.

650W should be able to deliver todays best graphics cards so I wouldn't agree that it is a shame. Even in SLI or Crossfire as I've understood it.

Maybe they will follow the trend and create 1gigawatt powersupplys eventually but I've read from reliable sources that one never needs so much power today, but thinking ahead a few years then it could be a good choice, I guess.

For me, my 650W powersupply will give me more than I need for today and in the future.

Personally, I would not want a 650W PSU powering a dual HD3870X2 setup.... ;)

Because it would generate a lot of noise, yes?
