Zalman's new ZM1000-HP power supply has been designed with fan noise in mind. The heatpipe experts from Zalman have stuck two of these inside their PSU and added a slow running 140 mm fan on top of that. This winning combination results in one of the quietest PSUs we ever tested, especially considering it delivers up to 1000W of power via six independant 12V rails.
Sunbeam's Mini Plant is a wolf in sheep's clothing. The PSU comes in an ATX standard sized casing but offers up to 950W of power. With most other manufacturers this means that the PSU fan will be very loud, not with the Mini Plant. Actually the fan is the quietest we ever tested in the 900W+ segment, you can almost not hear it, even under load.
The Tuniq Ensemble is Sunbeam's latest high-end PSU offering. It comes in at a whooping 1200 Watts with a large number of connectors included. For all your SLI/CrossFire needs you have two PCI-E 6-pin and two PCI-E 8-pin connectors available. Sunbeam has focused on making this a stable and efficient power supply and did a great job, the efficiency rating during our testing is well above 83%.
The SuperNova 600W power supply from AXP (in Europe) and Xion (in the US) is designed to be a cost effective solution for people who do not use things like CrossFire and SLI in their system. Another important feature of this modular power supply is that it has a number of LEDs placed in vital spots to give that PSU a really pretty outward appearance.

Its modular approach lets you start small and attach just the cables you need as your power requirements grow. For a price of only $200 you get a solid PSU that has up to six PCI-Express VGA connectors.
GIGABYTE's Odin GT line of power supplies is the world's first PSU series that allows software control and monitoring. From within the GIGABYTE P-Tuner software you can adjust voltage levels, fan speed and get detailed monitoring info about your PSU like power draw. In addition to that we found out that the unit also has a very high efficiency of over 84% and good voltage stability.
Akasa's new PowerMax Family of power supplies offers power for demanding gamers and enthusiasts. We test the 1000W version today which has a large number of connectors on extremely long cables in an ATX standard sized case. The unit boasts a high efficiency of over 82% which may even help you save some money on your electricity bill.
Zalman's new ZM850-HP PSU uses two heatpipes to transfer heat away from the hot components on the PCB to the rear of the unit. The hot air is then exhaust by a slow running 140 mm fan. This design allows Zalman to run their fan much slower than the competition. In the end this results in one of the quietest PSUs we have ever used, especially if you consider the 850W maximum load.
Corsair's brand new VX450W power supply comes with a maximum load of 450W. While this may not sound much it is absolutely sufficient to power most of today's systems. The PSU has a very high efficiency of over 83% which allows the fan to run slower because there is not so much excess heat to get rid of. In our fan noise testing this extremely silent unit leads by a large margin over all other PSUs tested so far.
PC Power and Cooling is without doubt one of the best power supply manufacturers out there. Recently they have been bought by OCZ and we are now seeing the first products which are geared for the masses.

The Thermaltake Power Express 250W is a video card power supply specifically designed for the needs of current high-end video cards. When you have an older PSU you may not be able to run Crossfire or SLI because the PSU can not supply enough power for the video cards to run stable. When installed, the Power Express will supply 12V to your video card(s), taking a lot of strain off your main power supply.
The be Quiet Straightpower 700W is a high-quality power supply for power hungry gamers and overclockers. It sports features like two PCI-Express power connectors and an 8-pin CPU power connector.
