As said before the 750 and 850 watts RM is not made by CWT but by Chicony Power Technology
Its different then the other models in RM series this is both good and bad
The good news is the 5v bridge has not been forgotten so no problems with dead 5v pin on the 24 pin ATX cable
The bad news is this
The VRMs use two Taicon electrolytic caps for ripple filtering. All the other caps in the secondary side are by Ltec. Corsair's cap choice definitely isn't the best. Lowering production cost was apparently a prerogative, yet the warranty for this product is still set to five years
The filtering caps in the secondary side are provided by Ltec—not our favorite choice. We think Corsair should use higher quality caps here since this unit usually runs in passive mode. Time will tell if they were right to trust Ltec caps or whether many units will be RMAed instead.
All capacitors on the secondary side is Taicon and Ltec
Soldering quality isn't the best we have seen. The production line probably needs some time to hit optimal quality levels. CWT implementations are clearly superior in this area, so Chicony has some catching up to do. The large metal bar shown on the fourth of the above photos is used to transfer earth to the modular panel, while the smaller bar is used by the +12V rail. We also spotted three current sense resistors right in front of the +12V pads on the modular PCB.
The fan enters the party rather late (allowing for high internal temperatures)
Capacitor choice in the secondary side
Corsair Link USB header not included
Limited functionality of the Corsair Link software (only monitors fan speed and +12V current output)
