I have heard that it frys your components. Is that true?
Well, it's not like it will automatically destroy you components (obviously), but Coolmax is definitely a company you should stay away from when choosing PSU. I know hardwaresecrets tested one of their 750W powersuplies some time ago, and it was basically a 450W powersupply with a fake sticker on it.
I can almost bet on that you don't need a 900 Watt powersupply anyways.
