Im planning to crossfire two MSI R9 380's and was wondering if this 750W PSU is enough for that purpose
yes, it's plenty. a 650 watt would be too. maybe you would prefer a quieter, more efficient 650 watt at that price.
what psu would you suggest for that price at 650?
coolermaster VSM650, but it only has two pci-e connectors so you'd have to use molex to pci-e adapters. there's the seasonic S12G 650, though it's not semi modular like the other two. $5 more you can get the XFX XTR 650 full modular that's basically the same internally as the seasonic S12 G, but I don't know if you wanna be spending more than the $89.99 tha 750 B2 costs.
really im looking at the 750 b2 at $49.99 on NCIX US so im pretty sure that that's the best solution for me. Thanks for the help though!
which NCIX? http://www.ncixus.com/products/?usaffiliateid=1000031504&sku=97531&vpn=110-B2-0750-VR&manufacture=eVGA
