    Been waiting for these. Mostly for the epic praise they will receive in reviews :thumbsup:

    Also: 7 year warranty.

    Very nice, but I am scared to hear what kind of price they will be commanding...

    I'm glad I can't justify buying one of those...My Corsair HX620 is already more than my system needs...but ooh-ooh-ooh...those are sure sweet.

    Wife's system has that same ps, the 620HX. Mine has the 850HX. Still have yet to see a new gold/plat. power supply that's priced good enough to make me switch either of those for a new one, given the high price of the gold/plats. out there and how long it'd take to recoup the extra cost in energy savings (years!)

    Just not worth "upgrading" a power supply that's already 80plus cert'd. for a level or two higher in efficiency, if that's the only reason to upgrade. Failure, sure, spend the $$. Otherwise, I'd put the bucks into a better gpu or cpu or SSD.

    ^ The 80+ silver is already really high efficiency so a gold or platinum PSU would probably pay itself back in something like 10-15 years depending on use.

    Thanks for the link. I don't think the price is really terribly far off their other PSUs. The 850 gold is ~210 so for another 30 you get 1000 and its platinum efficiency is more of an afterthought on the price.

    That's actually not a bad price at all. Corsair HX1050 is $220 and a $20 MIR. But that's two efficiency grades below and manufactured by CWT.

    btw I love the fact that you can switch between normal and hybrid fan modes :)

    Yeah that's a nice feature. I actually don't really like the hybrid mode on my X-650 because the fan only turns on every 30-60 seconds or so, but when it does it ramps up quickly for a second or two before it shuts off. I'd rather have it running constantly at a very low RPM than short bursts of high RPM like it does in hybrid mode.

    Yeah. Mine makes that swoosh sound sometimes when the load spikes up momentarily. Then it's back to idle watts shortly afterwards, and off goes the fan.

    Edit: Hmm, it seems to be the CPU cooler instead x). The fan spins up only at the highest loads I can get and at that point its sound is completely submerged in CPU and GPU fan noise.

    I knew Seasonic would impress. Didn't expect anything less. Seriously, 2% voltage regulation? Corsair HX1050 does 3-4%. And add the hybrid fan control and two grades better efficiency, the Platinum 1000W is actually not that expensive at $40 more than HX1050.

    Sure 2% regulation is cool, but does it really make much of a difference compared to say 5%? The computers are going to run the same...

    5% is the ATX spec upper limit, I'd rather have less than that...

    I'm not expert....I leave the expert opinion to JonnyGuru. But from what I've seen over the years, tighter voltage regulation, esp. under heavy loads, is usually indicative of a power supply's overall component robustness, and design and build quality.

    I do understand that the ATX spec allows the major rail, the +12V rail(s), to droop to 11.4V under full output, and that computer components are designed to work with that low a voltage being fed. And, as you suggest, most bog standard computers probably aren't going to be affected by that.

    But this power supply, and those built to higher standards in voltage regulation, efficiency, ripple/noise generation, etc., aren't focused at or marketed towards the mon-n-pop email/Youtube/web surfing crowd. Instead, these power supplies are focused on the enthusiast crowd, the same crowd that will overclock their cpus, gpus, and darned near anything else they can push in their builds.

    And when you're overclocking, voltage regulation does become important in relation to stability of said overclocking, all else being constant (overclockability of the cpu, mb, RAM, etc.) Too much droop from the power supply's output will cause the motherboard's voltage regulators to work harder to maintain a stable platform.

    And tied into that is ripple/noise control. The power supplies that can provide 1-2% voltage regulation at full load typically can also suppress ripple/noise generation very well, too. And this is another area that can affect ultimate overclocks.....the mb/cpu's VRM's aren't having to work as hard "screening" out the garbage of overly high, but within spec, ripple and noise.

    Again, this is just my opinion, but seems to be borne out by serious overclockers finding it easier to achieve stability with heavy overclocks when using "overbuilt" power supplies vs. ones that just meet the ATX specs.

    I'd much rather my components be fed as clean and stable an electrical signal as possible...the components shouldn't have to work as hard as they would being given an electrical signal that's within spec but dirtier and producing lower voltage than a ps that can maintain tight voltage regulation and a clean signal.

    This is why I'll pay a bit extra for a power supply that has first, tight voltage regulation; second, suppresses ripple/noise generation well; third, is modular; and fourth, is efficient. For mom-n-pop, probably won't be an issue.

    Nice review! Only thing that bugs me is, that they never measure fan noise. So a comprehensive review and then just nothing in that department. That's a bit disappointing.

    If they were unable to measure fan noise, it says something about how quiet the unit is :p

    They don't measure it in general in their reviews. That's why I switched to kitguru a while back. Their reviews are top notch in that regard :)

    Nice to see that JonnyGuru dropped scoring "Aesthetics" and instead have "Build Quality". Its a PSU, not designer swimwear. :D

    Does kitguru measures fan noise in anechoic chamber like SilentPCReview, or use some magic wand from ratshack?
