For this specs. is it enough to have a 600W PSU or do i need more. I'm not planing in the future to have more than 1 GPU. AMD FX-8120 X8 Black Edition tunned @ 4.2GHz XFX HD 7850 Double Dissipation Edition 2GB Corsair DDR3 1866MHz 8GB Dominator GT Kit CMT8GX3M2A1866C9 120GB Vertex 3 OCZ SATA3 Seagate 1TB SATA3 64MB Gigabyte 890FXA-UD5 Cooler Master 600W RS600-80GAD3-EU Silent Pro Gold APFC Modular FSP Aurum 600W Enermax Modu87+ GOLD 600W EMG600AWT Corsair CMPSU-650AXEU 650W AX Series Corsair CMPSU-750HXEU 750W HX Series so which one i will not pay more than 120-140$
I would recommend a 750 watt. Your power draw will be around 400-450w with that setup while playing a game, so a 600w will be adequate for the first couple years but after that you will be pushing max capacity from the PSU due to degradation. I would get the HX750 as Sogetsu said, it is the best PSU of that bunch.
I grabbed an HX850 but I'm a little worried I should have held off on the purchase for power. It is going to go with a Sabertooth Z77, i7-3770 with a corsair H100 to cool it, GTX680, 4x8gb ram, 2 hard drives, 2 disc readers.
Ack. I havent done kW calcs on the new stuff, it should be ok if you dont SLI but mighta gone 1k PSU.
Thanks for the advice. The price difference is also very minimal between then HX850 and HX1050. It would be nice to have the freedom to toy with things further as I go on. I went with newegg and near as I can figure, the RMA looks to be rather painless within the 30days and they even have "I'm a dummy that didn't order the right thing" as an option ^^
As long as you dont get the HX1000 you will be fine. Its really 2 500 units put together and has issues occassionally because of that.
As a comparison, I have a Phenom II 966BE @ 3.8ghz, 16gb 1333mhz ram, and TWO Radeon 6870s. In Battlefield 3, I pull about 550-580watts at the wall. With Prime95 and Furmark I have hit over 600watts. So with a single videocard, you shouldn't ever hit above 450watts.
