Twenty five years is a long time in the personal computer marketplace. That's how long PC Power and Cooling has been in business. They've been a part of OCZ Technology Group since 2007, and they have a number of resources on their web site including an FAQ, a terminology page, and a product selector page to help you choose the right power supply for specific workloads.
One of the things PC Power and Cooling does provide for a small fee is a Certified Test Report showing the results of a 12-point performance test. Their Silencer line comes with a 7-year warranty including full tech support. It also has been certified by NVIDIA to support their Dual-GPU video cards. Their products also carry the 80 Plus certification which requires an efficiency of 80% or higher.
Thermaltake has been in business since 1999 and has a strong reputation in the DIY community for producing high quality products. They have a number of different power supply product lines featuring modular connectors and a wide range of wattage capacities. The latest Toughpower XT series comes in four models from 575 to 875 watts and up to 89% efficiency. Support for up to eight SATA drives is possible with the 775 and 875 watt models.
Thermaltake has a web page with links to a number of resources to help you choose the right power supply. Their power supply calculator helps you add up the power needed by different components in your system. They also offer the Purepower Series targeted at the high-end DIY gaming market.
While these three companies certainly aren't the only ones out there, they do offer quality products and have the kind of technical information you'll need to make an informed purchase. You'll definitely want to do your homework on all of these sites if you're looking to upgrade your PSU. Don't be afraid to spend a few more dollars to get a little extra power.
