If you would like to keep it 850W, check out the Corsair Power Supplies, they're beefy and reliable.

Hi Tom Thumb, The CP-850 will not fit in an Antec 300 regardless of what the motherboard size is. The CP-850 like CFTait has mention is made exclusively for Antec 1200/P183/P193. I would recommend getting another power supply, maybe a TP-750 from newegg. TP-750 - $90 After Rebate http://www.newegg.com/Product/Product.aspx?Item=N82E168... TP-750 w/blue led fan - $120 http://www.newegg.com/Product/Product.aspx?Item=N82E168... Antec m 0 l tom thumb May 6, 2010 12:46:53 AM Actually, I'd rather change the case then the PSU as I haven't bought either yet. Here's another question, will that PSU fit in a CM 690 mkII? (btw thanks for your help guys) m 0 l JackNaylorPE a c 139 ) Power supply a c 216 V Motherboard May 6, 2010 1:07:22 AM The PSU fits in 5 Antec cases (1200, P183, P193, DF-30, DF-85), no others. And you can't but the DF series yet. This is what you want .... though price just jumped $30 on 1st one since yesterday. http://www.newegg.com/Product/ComboDealDetails.aspx?Ite... http://www.newegg.com/Product/ComboDealDetails.aspx?Ite... m 0 l tom thumb May 14, 2010 8:02:56 PM Best answer selected by tom thumb. m 0 l Can't find your answer ?
