GoKawiilPhanteks AMP GH 750W PSU tested: solid efficiency but 450W limit on 12V-2x6 port
Tom's Hardware reviewed the Phanteks AMP GH 750W, a Helly Technology-built power supply that replaces the Seasonic-based AMP line. The unit delivers strong 12V voltage regulation, low ripple, Japanese capacitors and an 8-year warranty, but its 12V-2x6 connector is limited to 450W of output. Despite that restriction, the reviewer calls it one of the better mainstream 750W options given street prices under $90.
