Aywun Megapower Elite 550W Review

[c_hegge]

Yup, that's half bridge alright. Out of curiosity, what are the switching transistors? If they were 13007s, then I wouldn't be surprised at all if it couldn't deliver more than 300W. I've found that to about the limit of 13007 transistors.

It allso lacks APFC, which is required for 80plus certification. There's no way that would comply.

I have recieved an email from 80plus requesting some internal pictures of the Aywun, which I have now sent. I'll keep you posted on what happens.

That 300W Highpower blew up at 300W (12A @ 25A = 300W, unless other rails were being severely loaded too)? I thought Sirtec at least produced honestly rated PSUs. I know that PSU is only 230V but even still...

let me know if they want better, detailed pictures of the 450W as well. those pics were just with a phone cam I'll email them

Wester:

To be honest I can't remember if I had the 5 and 3.3v rails loaded. I use a fixed resistor bank for them, but a variable active load on 12V. I can't remember if I had the bank plugged in at the time.


Obivoulsy no OPP is present either or it would have just shutdown instead.

Will do. I haven't heard back from 80plus after sending them pictures of the 550W yet.
