Okay will this power supply support my computer?

Im getting a 650w power supply by corsair my computer currently runs On the stock 350w PSU for the hp pavilion elite m9200t. I am upgrading to the HIS 6950 x iceq turbo which recommends a 500w power supply. I am switching cases to a Antec Lanboy moduler case. I'm moving the parts from the old one to the new case. Will the PSU support it? I ask this because the case has 5 stock 120mm blue LED fans which my case does not have. Thanks
