Digital Storm--VERTUE, change any components?
Some of the the Corsair "AX" and "TX" range power supply units (PSUs) are manufactured for Corsair by SeaSonic.

Personally, I'd go with main system RAM from one of these: Corsair, Mushkin, Kingston, Crucial, Patriot. (The "gskill" brand is the house brand over at Newegg, and I don't know the OEM.)
By all reports, the NVidia GTX 770 (retail around $400) card runs pretty well. According to Tom's Hardware it is "...basically a GeForce GTX 680 with higher clock rates, improved cooling, and a lower price tag..." Although to be honest, I am content with my AMD 7950 (retail around $300).
