Need help chosing a PSU Hi all, I'm in the process of upgrading my computer, and I'm unsure what PSU to get. I'm thinking 650-750W (with modular cables), but don't know which brand to go. The three I'm considering are Thermaltake, Zalman and Corsair. Specifically, these PSUs: Thermaltake Toughpower 750W Zalman zm750W Corsair TX 650/750 Does anyone know which is best? For those wondering, PC specs are: CPU: Intel Quad-Core Q9450 Mobo: MSI X48C Platinum RAM: 4GB (I'll be running a 64-bit OS and programs like Photoshop) HDD: 2x 80GB SATA (in a RAID0), 1x 250GS SATA 2x DVD burners Graphics=: Currently XFX Geforce 6800GS, soon to be MSI Geforce 9800GTX (Overclocked) I have a Thermaltake TR2 430W at the moment which I'll be using until I get a new PSU (which should be less than a week), which I've been told will be ok, so long as I don't max out the PC or have it like that too long (basically all I'll be doing until I get the new PSU will be installing the OS and basically setting up the computer - I really don't want to burn it out). So if anyone can recommend something, it would be much appreciated.
