Hi there guys. Not sure what size PSU to get. I recently shelled a lot of dough for PC parts. I'm building my first PC and want to make sure I can give it enough power, with a little overhead. I may wish to overclock the processor in the future so that needs to be taken into account. From what I understand I should get either a US or Taiwan made PSU, and that constant voltage and amperage are most important. I'd also go for one that's Gold 80 Plus certified, if needs be. Here are the parts: Gigabyte GA-X58A-UD3R mobo Intel i7 920 CPU (Will want to overclock later in the CPU's life) ATI HD 5870 GPU 6GB (3 x 2GB) Corsair XMS3 DDR3 PC3-12800 (1600 Mhz) AKASA Nero S Premier Cooler Corsair H50-1 Hydro Watercooler (Will probably use this with OC'd processor) Scythe Setsugen GPU Cooler Samsung F3 1TB HDD I also already have an old Samsung SyncMaster 243T LCD monitor, a Creative i-Trigue 2.1 Sound System, HP Photosmart 2575, HP Keyboard and Wireless Mouse. And I will probably change the keyboard and mouse for something more fanciful later on. I will be using Windows 7 64bit Home Premium. Your help is much appreciated.
