I thought these Rosewill are modular PSU, i double checked they are half-modular. Because the MIR and non-modular Corsair are the reasons I'm not decided yet. non-modular kind of bothers me, if the positive of the Cosair PSU is way way better than the Rosewill... or is anyone have a better option? try to have the Case and the PSU around $100.
I totally blew it on the modular part - I apologize for the bad information. Here's a hardware secrets review of the 650W Hive (it received their Golden Award). http://www.hardwaresecrets.com/article/Rosewill-HIVE-650-W-Power-Supply-Review/1460/1
Here's the specs for the 650 and 750W models. http://www.realhardtechx.com/index_archivos/Page2917.htm
Hope this helps make an informed decision!
