Pretend that the computer is a human being. The CPU is its brain, the GPU is its heart, the motherboard is its skeleton, and the PSU is its digestive system. For gaming, you need a LOT of heart, normally, with Skyrim being deficient in graphic quality, it runs with less power for that organ than a normal gaming PC. A cheap PSU will starve the system to death or poison it. The brands I think you can trust all models from are Corsair, Enermax, Fortron, Seasonic, and (well, memory freak-out time -- OK, got it) "Sparkle".
Most of the Antec models have been great, but in the past they had at least one bad line, so I don't feel I can trust them quite as much.
The biggest problem with the greatest majority of PSUs, and I don't trust Rosewill myself, is that they are entirely likely to destroy the rest of a computer when they fail.
P. S. Because the majority of the PSU brands are not to be trusted, most of the component producers have chosen to greatly overstate the current requirements in watts, to encourage people to pick the highest rated among the cheap generic stuff. A quality Corsair power supply rated at 450 watts is very likely to provide MUCH more current than a Coolmax or Raidmax 1000 watt rated cheapie.
Many of the power supply makers include a simple calculating function on their sites adding up advertised wattage requirements for various components to allow a shopper to obtain a maximum wattage requirement (which usually will equate more to the low quality PSU brands' claims of watts than to higher quality brands' more accurate numbers, no matter that the calculator is hosted on a quality brand web site). Since a 30%, minimum, usability count should always be added, it will cover that and then some.
Even the best brands will deteriorate with use, about 10% loss per year.
