I know it has the 6-pin connector, but my computer I think its the C521 with the big case, if so I probably have this :280 Watt DC Power Supply. I can't tell for sure until I get home.
Thanks

I hope it is the big case ..because if its the 4.5" narrow case then even if the PSU fits..the ventilation will be constricted.
