CyberPower: 4.0 GHz QX9770 and SLI GTX 280s

Power
We measure power consumption using a Kill-A-Watt device at the wall outlet. Idle indicates a measurement taken in Windows with no applications running. Max indicates the maximum power draw with the system fully loaded (running four instances of Prime95 and 3DMark06 simultaneously). We've also indicated power draw with just the CPU loaded.
For the hardware present, these results are quite good. Our Tri-SLI system maxed out at 671W, and that only had a single 1200W power supply (versus the 1000Wx2 in this system).
Noise
We measured noise with a sound pressure level (SPL) meter, at distances of 24" and 48". The case fans and video cards dominate the noise produced. For reference, ambient noise was approximately 37.5 dB(A).
This is a large system, with seven 120mm fans, and even so it manages to remain reasonably quiet. It's definitely audible, but most would find the low hum from the larger fans easy to deal with, and of course the fan controls allow for noise reduction.
Temperature
In most cases, we utilize CoreTemp 0.99 or nTune to measure CPU temperatures. In this case, we also used SpeedFan and the system monitor as additional checks. The NorthQ/Asetek self-enclosed water-cooler (which our friends at FrozenCPU have also provided us for review) is silent and extremely compact for a water cooler, but was registering temps hovering between 50-55C at idle.
In the System Monitor screenshot, you can see the idle temperature registers at 60C in the BIOS. This seems quite high to us, and load temperatures didn't alleviate our concerns. We wanted to really stress the CPU, so these were taken with four instances of Prime95 running (one assigned to each core).
Even with a large amount of case circulation, these temperatures are uncomfortably hot. That's not shocking with a 4.0GHz quad-core CPU fully loaded, but there's certainly some concern about long-term stability at these temperatures.
Update: On August 21st, Intel disclosed the maximum TJunction values for their 45nm processor line. As pointed out by readers, the Tj. Max number reported by CoreTemp and NVIDIA's System Monitor was 105C, whereas the official value from Intel for the QX9770 is 85C. Armed with this new information, we first altered the offset in CoreTemp 0.99.1 to bring Tj. Max down to 85 C, and reran the tests at idle and load. We also downloaded the latest version of CoreTemp (0.99.3) with the Tj. Max changes incorporated and measured again at load, reading the same values. This shows the Xtreme XI and the Asetek cooling solution in a much better light.

for this kind of money, gat a maingear and live happily ever afterbill3 - Friday, August 22, 2008 - link
They get a lot of crap online, but I think people just like to whine. My brother bought a rig from them a while back and it's been nothing but great, and the price was great too, practically cheaper than you can build it yourself. And saves you the hassle, which as I age becomes a bigger factor, I dont really enjoy building my own PC's anymore, installing windows and all that crap.The customizability is what sets them apart, from buying a crap Dell or a PC from Best Buy or something imo. And the fact you can hand pick name brand quality components. The main downside imo is the 2 week build/ship time (newegg can have you parts to you in 2-3 days if you're building your own, and I like instant gratification).
But anyway, now on to my comments about this rig and away from general comments about cyberpower..my main complaint is for a 5k rig, this isn't nearly as extreme specced as you'd think it should be. Terabyte HDD's are rapidly nearing $99 nowdays, so you should get at least two of those imo (hell for 5 k, if not 3 or 4!). The fact you only get Vista Premium? Should get Ultimate befitting this monster rig. And then the RAM, I was browsing PC's in Best Buy the other day and noticed a "budget" $600 PC with 6GB RAM already! Granted it may be an overclocking thing or something, but this rig should come with 16GB RAM or something like that you'd think (8GB at the very least). Cant really argue with the video cards/PSU's though.

It isn't always folks that "just like to whine," I tried to buy what looked like a great deal on system from them about 8 years ago that turned me off of them completely.
This was back when the PIII was just moving to on-die cache...(back in the good old Slot 1 days...) Ordered a system with the on-die cache... system comes with the older version with external, half speed cache, that was about $40 cheaper to buy...
Call Customer service... generally took 30+ minutes to get through to anyone in their call center... system had other problems as well... just not stable... problem with the motherboard... could not work with anyone in customer service going up the chain. Finally ended up disputing the charge with Discover... Cyberpower never responded to Discover's dispute of the charge. Eventually they sent a prepaid shipping label to me to send the system back.
Had the system worked fine, I would have been a happy customer like your brother. I figured they could put it together for less than I could buy all the components... then they didn't ship me what I ordered... then they had lousy customer service and tech support...
They may have gotten better... or they may have found that the go for the cheap customer and hope for the best is more profitable...

They use two 1000W PSU for a system that uses less than 600W from the wall outlet? A single 1000W PSU should have been enough.HOOfan 1 - Friday, August 22, 2008 - link
If you look at some of their in magazine ads, they will often show a configuration like the system above with only a single 420W generic PSU.HOOfan 1 - Friday, August 22, 2008 - link
Also to add, this system doesn't even use 600W in their test. They measure AC draw from the wall outlet. Assuming these Thermaltakes can be 83% at those lower loads. 5798 * .83 ~ 481 So the system isn't pulling any more than 500 Watts of DC in their tests. Considering PSUs are rated on DC output and not AC input, this system is only drawing ~25% of the theoretical power available to it.Christoph Katzer - Friday, August 22, 2008 - link
Wasty, They could have gone with two much smaller PSUs to keep load and therefore noise low on both. The two 1k units are not necessary and waste a lot of budget for the system. Too bad these companies have no idea how to choose sufficient power..bill3 - Friday, August 22, 2008 - link
Oh and I forgot to mention one thing that amazed and made me envious of my brothers cyberpower..he got a windowed case and the cabling/routing they did was incredibly clean and minimal. I mean, no clutter whatsoever, just perfect. I'm just sloppy and stupid, but I hated staring at my cable clutter in my windowed PC for years (why I didn't buy a windowed case this time hehe)HotdogIT - Friday, August 22, 2008 - link
Remember the HardOCP reviews, where they tested the technical support? Yeah, I loved those, and miss those. Obviously it ended up killing their H-Consumer line, as it cost a lot of advertising dollars, but it was so unique, and special, and cool.You guys should do that. That's what I'm cleverly hinting at with my reminiscing.

Yea that was great, it actually swayed me to purchase a comp from cyberpower because they had a few decent reviews on there.
