The new psu cm gx series had 1 good psu gx 450 hardwaresecreet and gx 550 no review valid, gx650 fail
^+1 true as far as i've researched the CM GX psu line.
The GX 450 has different internals from another oem and is a good unit.
I've read numerous reviews of the GX 750 and it's also a Fail.
OP where do you live?
