Found this bad boy on sale, literally 25% cheaper than ANY other 850 W Gold rated PSU I can find. Like, 15 Euros more expensive than an XFX Core Edition PRO850W. It's 850 W, it's got all the cables I could dream of, modular. I'm planning to upgrade to a new graphics card soon, something high-end, but probably not multi-GPU. Would this be a good investment, considering that I will most likely not be using more than 500 W during the next couple of years? Or am I asking a stupid question since my VX 550 should, theoretically, be able to support a 300 W graphics card (like an OC'd GTX 580)?
