Shades of the GX line; Coolermaster swings for the fences, but a competitor (pick one) in the outfield snags it and throws this one out trying to stretch a single to second base.

A lot of hype and little delivery for that price tag of course. Lower that price down to $200 and then we may be talking. The efficiency under low loads was quite poor. I'd like to bash the 5VSB regulation, though that's going to be unimportant and unrealistic with the majority of consumers, having load changes on that rail. Though if you are charging multiple devices I'd rather have it at 5V than 4.75V.

At least the transient response performance was really good. The PWR_OK signal, eh. Aris, do you think that transient filter is really enough? I have a feeling it would fail EMI testing, only 4 y caps, 4 x caps, and 2 cm chokes on the unit.

Overall, Cooler Master paired with the wrong OEM.

the transient filtering stage looks complete since it has more than the required X caps, however you can never know unless you actually test it. I have the equipment and knowledge but I lack the time to do it :)

What are the exact requirements? I know what the ATX spec says but you have units like the FSP Hydro G 750 that failed by a good margin with 4 y caps, 2 x caps, and 2 cm chokes. So when talking about a 1200W unit with 4 y caps, 4 x caps, and 2 cm chokes, those 2 extra x caps are enough to do the trick?

The performance per dollar chart was great, it showed how badly overpriced this unit is and that there is a lot which could be improved on for the money spent on the unit

It's seem like the solid polymer caps on front side modular PCB's not from Nichicon, I think it belongs to Unicon taiwan ( UPT series ).

Sadly it is more than the AX1500i, lower efficiency and specs overall and a lower warranty (7 year vs 10 year).

If someone is going to spend that much on a PSU It would be better to go for the Corsair.
