There used to be a time where 600W power supplies were considered overkill for all but the craziest of enthusiasts, modders, and overclockers. When the 850W PC Power & Cooling unit was released a long time ago, owners regarded it as a rare gem. It was both unaffordable and overly extravagant, and virtually no system was able to stress it to the limit. But now, we are finally in the kilowatt era. Today we have two members from the kilowatt club: the Tagan ITZ 1300W and the Thermaltake ToughPower 1200W. The ITZ line Tagan's newest flagship line of power supplies meant to carry Tagan into the industry spotlight. The last Tagan power supply we reviewed was the Tagan TurboJet 1100W. Its unusual packaging and high quality finish impressed us. However, while the performance was by no means lacking, we would have a hard time claiming it to be outstanding. We shall see if this unit steps up to the challenge. Aside from the 1500W behemoth that was recently released by Thermaltake, the ToughPower 1200W is their highest-end power supply. Thermaltake power supplies have always performed well. They have never been known to be the ultimate power supplies, but their performance has been better than many brands on the market. This unit is longer than the average power supply and features a huge 14cm fan.

When you say "good power supply" to newbies, most just look at the wattage and buy the biggest wattage power supply for the cheapest price. This is a costly mistake. Slightly more experienced users will look for brands like Antec, Thermaltake, Enermax, etc. These are very reliable and perform well enough for most users. However, seasoned enthusiasts and overclockers know that few companies match up to the name PC Power & Cooling. The quality of their units has been legendary and the units are highly coveted components. Earlier this year OCZ Technology, a leading memory manufacturer with products we frequently review here at Phoronix, had acquired PC Power & Cooling. One of the products to come out recently since then has been the PC Power & Cooling Silencer 750W power supply. The PC Power & Cooling Silencer 750W has a massive 60A single rail and four PCI-E connectors. It is ATI Crossfire certified and the Crossfire Edition refers to its bright red paint job.

During our natural sub-zero overclocking event this past winter we had chose to use the Mushkin HP-580AP power supply. The Intel processor was running 133% of its rated speed, and through the entire process the power supply was providing clean and stable voltages when monitoring the rails with multiple digital multimeters. However, now we are going back to look at this Mushkin power supply and provide some additional thoughts on this 580 Watt quad-rail modular PSU.

With time we have seen computers go from a single GPU and processor to dual and quad core CPUs with a number of different options for multi-GPU systems. As we have shoved more and more into our systems, the power supplies have gone from a single +12V rail to multiple +12V rails. Dual +12V rails has been very common in recent years, while recently at Phoronix we had looked at a few quad +12V rail power supplies such as the SilverStone Zeus 750W and the OCZ GameXStream 700W. However, the more +12V rails does not necessarily make a better power supply. What we are looking at today is one of SilverStone's newest power supplies, which was recently on display at the Consumer Electronics Show. The SilverStone Olympia OP650 is a 650W power supply that supports both the current 6-pin PCI Express power connector as well as the new 8-pin version, and supports 54 Amps on its single +12V rail.

While Tagan is not a center point with consumers for power supplies here in the United States when compared to Antec or SilverStone, they are working on improving their presence. The Tagan power supply that had caught our attention was the TurboJet TG1100-U95. This power supply provides 1100W of power and is geared for MultiGPU and multi-core systems. The Wattage may be high, but so is its price tag at $399 USD.

The last time we had a Seasonic power supply in our hands for testing was the Seasonic S12 330W back in April of 2005. Today we happen to have our hands on a new Seasonic power supply, the M12 700W. Are times still going well for Seasonic? We will see in this article as we fire up this modular power supply.

It has been quite a while since we had anything from Ultra Products in our facilities for testing, but recently we decided to take them up on an offer to look at their X-Finity 500W power supply with dual 12V rails and active PFC. This power supply is also NVIDIA SLI Ready, offers a 135mm fan, and uses FlexForce cabling.

NZXT is known as a company of gamers that design creative and attractive cases for gamers. How well is NZXT able to forge a power supply? We shall find out as we throw the NZXT Precise 650W up on our workbench.

While OCZ Technology is primarily known for their vast selection of memory products, they have had interest in developing cooling and power supplies as well. For some time they have had the OCZ PowerStream and ModStream PSU series; however, only recently did they unveil their high-performance successor: the GameXStream. The OCZ GameXStream power supply is meant to suit high-end power-hungry systems for gamers, enthusiasts, and power users. Currently the GameXStream is only available in two flavors: 600W and 700W. Some of the features for this power supply unit include OCZ PowerWhisper Technology, Multi-GPU ready (NVIDIA SLI certified), OCZ ConnectAll connectors, and Active PFC.

If the popular 500~600W power supply units are not enough to suit the growing needs of computer enthusiasts, SilverStone Technology has released a phenomenal 750W continuous power PSU. With providing just over the equivalent of one horsepower, the SilverStone Zeus ST75ZF features quad +12V rails, dual PCI-E 6-pin connectors (plus the option for two more), industrial grade components, and active PFC. Is SilverStone's ST75ZF the new front-runner for high-end power supplies?
