Our Score:


Opening up the Twelve Hundred is a simple case of removing two thumb-screws. Inside, the Infinity i7 Phoenix is a tidy affair, with all cables neatly tied away. The interior is dominated by the CyberPower liquid cooling system, which combines the reservoir and pump at the front with a radiator cooled by no less than four 120mm fans in a push-pull configuration at the back, all hooked up to an XSPC Delta V3 waterblock. This results in the CPU remaining very cool (below 50 degrees under load) despite its heavy overclock, but it also means this is a noisy beast. Even with all the case fans turned to their slowest setting, the Phoenix is audible from quite a distance, and very distracting close to.

For some reason, turning the fans down to their minimum speeds for a slightly quieter experience resulted in the overclock regularly failing, requiring a cold boot. Since the CPU remained within operating temperatures, we can only assume some other component was getting overheated, and this may be an issue unique to our specific system. While on the topic of noise, it's also worth noting that the 850W CoolerMaster modular PSU used in this system developed an irritating whine after a while. However, given CoolerMaster's good reputation and usual quality, we hope it's a once-off fault.

The system is based on Asus' socket LGA1366 X58 P6T motherboard, which is apparently a popular choice among system assemblers as it's also used in the PC Specialist Vortex i950. That's hardly surprising though, as this is essentially the same board as the P6T-SE we reviewed and gave an eight out of 10 last year. While not quite as fancy as what we would expect given the Phoenix's price, it's reliable and provides all the basic features you need.

Asus' board plays host to the CPU, which thanks to its low-profile water block doesn't require an enormous obtrusive heatsink. As already mentioned, it's an Intel Core i7 920 overclocked to 4GHz, which can handle anything you'd care to throw at it with consummate ease. It's backed up by a ridiculously high-end 24GB of 1,333MHz DDR3 RAM, provided by six unadorned Kingston 4GB modules. This is pretty much the most memory you will find in any non-server or high-performance PC, and it's a large factor in the machine's price. To be honest, aside from the obvious bragging rights we think it's a waste of money and pure overkill, as there's almost nothing out there that a home user would run which will make full use of this. On the other hand, if you have the money then why not? At least you'll never need to upgrade your memory in the PC's lifetime.

there's just one massive problem with this system it has windows 7 home premium by default which only supports 16Gb of RAM whereas professional and ultimate support upto 192Gb after spending all that money it's a bit silly to give you more RAM than the PC can physically use

The one thing that I would like to see is the actual decibel (dB) rating for PCs. I often read reviews that refer to noise but if mentioned it is either quiet or noisy. Although this gives a general indication it can not be used to compare two systems. Personally I would be willing to pay more for a PC that does what is asked for whilst being quiet in the process. To me PC noise and quality sound system do not go together.

You're right of course, slight error on our part - though in fact the initial spec did list Win 7 Premium, all versions are delivered with Win 7 Professional (as was our test sample).


We'll look into it. And I couldn't agree more, any PC above £2000 should ideally be whisper-quiet (and we can but dream that one day, ALL PCs will be whisper-quiet).

Thanks for the review, I did the OC and tuning on this PC. Yeah, value is a bit poor with the current price of 4GB DDR3 sticks and yes it is overkill. Unfortaunately Intels ever receding release date for the Gulftown 6-Core CPU meant we couldn't go one better.

On the noise front, any systems from now onwards should be getting the i7 930 CPU which tends to run a little cooler than the 920 at high CPU clocks. I did a system in an Antec 1200 for a customer recently where the intake and radiator fans were all replaced with 'silent' red LED fans and we used a water cooled 5870 with only 3.8GHz on the CPU. This system was quieter than the review system here but there is always going to be a delicate balancing act of the overclockers trinity of performance, noise and heat in a system at this performance level. Turning the fans down to watch a Blu-Ray would be very unlikely to cause stability problems since most of the work is done by the GPU.

im sure if they dropped it down to 3.8ghz you could make it much quieter.

24gb that IS bizzare i still think 6gb is overkill.i wonder if you could use the ram as a hdd for windows .

nice system tho,i wouldnt say no to it.trouble is games on pc are become consolized? even with max quality and resolutions a lowly £100 gpu can run them with ease.maybe this will be a system for crysis 2.

hey initialised how about one for a competition?.

@betelgeus - I agree all that RAM is crying out to be used as a RAM disk, but you wouldn't be able to use it for a Windows install since it would require a constant power source (i.e. you would have to reinstall Windows every time you restarted the PC).

@Ardjuna: cool, good to know though I guess if you're spending this much cash on a top end rig you would likely spend a few quid more and plump for ultimate if only for the factor of having 'top' everything

One of the advantages of water cooling is to make PC's quieter, but in this case they have just used it to overclock the CPU. Maybe with some more modifications, eg. water cool the northbridge/southbridge/memory/GPU etc, this could be made to be a lot quieter. Also it's possible to make PC's quieter with sound proofing foam, but of course you would loose the pretty lights into the case. :)
