I recently decided i buy the NVIDIA GeForce GTX 560 1GB rather than AMD Radeon HD 7770 1GB and i know what it needs more power. For this reason should I get a better PSU, maybe 600W. I know people don't seem to like Xigmatek so i can get another brand, i just need to know if i need more power or not.
btw -- Xigmatek seems fine for cases. We seem to have several companies making cases who decide to branch out into other components, but are clearly small and don't have the proper resources (or motivation) to do a good job at psus...Cooler Master and Thermaltake being other examples.
