Überclok is a relative newcomer to the OEM system market. We first took a look at them while reviewing their entry/midrange Ion system and we liked what we saw. Good component choices, an honest and straightforward website, solid tweaking, and stability all conspired to give us a warm feeling. In fact, their youth and relatively unknown name (areas associated with reliability and long-term support for the consumer) was the only major flaw we pointed out. Today we're reviewing their only other model, the high-end Reactor.

We've already covered the company and the website in our Ion review, and won't rehash it here. Both the Ion and the Reactor come with a number of well-chosen options you can customize, and in general we like this segregation into two product lines. In theory, it should allow Überclok to focus on providing the best possible performance from each platform without getting bogged down in minor details. Their website still shows refreshing honesty, from their descriptions of video cards to their new Blog, and it's clear that they keep up to date with the market and adapt their strategy and product lines as the industry changes. We were sad to see the loss of the Tuniq Tower as an option, but according to Überclok it was so heavy that even with their custom foam stabilizers (which of course add to shipping hassle and cost), it was causing an unacceptable amount of failures.

    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.

    Corrected. Unless Matt can state otherwise (i.e. they changed PSUs for currently shipping systems), this is definitely a Cooler Master PSU.

    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:">

    Holy crap those things are pricey...

    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....

    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">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...
