This is a very high quality, high current power supply! At 900W you can easily run SLI or crossfire with 2+ graphics cards. I have never had a problem with mine in the nearly 5 years I have had it running pretty much continuously! The price is amazing for what it is, 900 watts and 80 plus bronze efficiency! Now it may not be gold, platinum or silver but 900W should be more than enough power that the waste to heat shouldn't matter unless you plan on running quad SLI/crossfire, this PSU will be more than enough! With the active PFC and 135mm double bearing fan you get great cooling along with excellent efficiency! With these features, and the high current gamer series branding, you get a PSU that looks great and preforms even better!
