Überclok Reactor: Balanced Performance

CINEBENCH R10
CINEBENCH places a heavy load on the CPU during the rendering tests and can utilize multiple CPU cores. The video subsystem has no bearing on the CPU rendering portion of this benchmark.
Impressive. The Reactor is keeping pace here with some much more expensive machines.
PCMark Vantage
In the past, we've used PCMark 2005 as one of our general performance tests, which uses a number of applications to simulate real-world system usage and provide a performance measurement. For the future we'll be updating to the Vantage suite that provides the same types of tests, some of which focus on the CPU while others also utilize the video subsystem. These tests include digital photo manipulation, webpage loading, video transcoding, HD content playback, and so forth.

SPECviewperf 10
We realize that not everyone out there is a gamer (Ed: Gasp! Say it isn't so…), and although these machines are intended for gaming, often the high-end hardware is useful for other purposes as well, such as CAD, artistic rendering, and medical software. SPECviewperf is a set of benchmarks that measure the OpenGL performance of packages such as 3D Studio Max, Pro/Engineer, SolidWorks, and other professional applications. The software is free to download and test on your own system, but be aware that running all the tests takes several hours to complete. We ran all tests at a resolution of 1280x1024.
We'll provide comparisons with other systems in the future, but the Reactor ran through the tests for hours with total stability.

Looks to me that the PSU in the actual computer is a Coolermaster unit and not the Corsair 1000W modular that you have listed in your specs. Not that it should make much difference, 1000W is way overkill here.JarredWalton - Friday, October 10, 2008 - link
Corrected. Unless Matt can state otherwise (i.e. they changed PSUs for currently shipping systems), this is definitely a Cooler Master PSU.Matt Campbell - Friday, October 10, 2008 - link
My fault on that one, I just didn't check it closely enough. Currently shipping units definitely list the "Corsair CMPSU-1000HX 1000-Watt", as shown here: http://www.uberclok.com/rPSU.html">http://www.uberclok.com/rPSU.htmlap90033 - Friday, October 10, 2008 - link
Holy crap those things are pricey...Christoph Katzer - Friday, October 10, 2008 - link
And again, what use is the 1000 watts PSU? They can build in half of the size, maybe a little more to keep it quieter, but 1000 watts....nomagic - Friday, October 10, 2008 - link
I personally would not mind getting a 1000W PSU because it leave more options open to future upgrades.After all, this is an enthusiast PC. There are many that are too lazy to build their own rigs from ground up, so instead they order one with all the basic parts assembled and cable management done. Then they can upgrade their rigs to their hearts' desire. (SLI, Crossfire, RAID...) They can even overclock it further if they like.
Therefore, having a 1000W PSU installed is a plus.

As stated below, at idle efficiency is likely to be somewhat poor, but at load it should get very good efficiency. I'm not saying it's an exact match (because I'm sure it isn't), but as an example the http://www.anandtech.com/casecoolingpsus/showdoc.a...">Zalman 1000W is above 83% efficiency with 120VAC from a load of 200W to 800W, and above 80% from around 150W to 1100W.If we take a baseline 80%, at 195W from the outlet the system idles at 156W, and at medium load it will use over 200W (so above 83%). That's of course assuming this is a good PSU, which I have no reason to doubt -- nearly all of the 1000W PSUs come from one or two ODMs, and with higher margins they also tend to use good components.
Is a 1000W PSU required? Absolutely not. Is it desirable? That depends on what you're doing. This system can go up to SLI GTX 280 cards if you want -- or even Tri-SLI I think? Probably to keep things simple Uberclok isn't giving a ton of PSU options. Now, if you were thinking of getting the Reactor with a GTX 260 and dual-core CPU, the 1000W PSU would drop below the 80% efficiency range at idle most likely. Personally, though, I'm not going to freak out about a 2-4% difference in efficiency. Features (i.e. number of connectors) are more important on a high-end PSU than rating and efficiency, IMO.

I guess at $3230 buying price you don't need to care about ~$200 less...
