Dissection – Part 1
Disclaimer: Power supplies can have dangerous voltages inside them even after being unplugged, DO NOT OPEN POWER SUPPLIES. It’s just not a good idea. Opening a power supply and poking around inside could very well kill you. Don’t try this at home. Don’t try this at work. Just don’t do it.
Now we’ll see how Enermax managed those fantastic ripple results!
I’ll start by popping the lid off and looking at the (amazingly quiet) fan.
The warranty sticker was indeed a pain to remove.
Here’s an overview of the PSU. Not as empty as the Platimax 1350W, but not exactly packed with stuff either.
Let’s look at the transient filter first, according to the specs this should be huge so as to deal with incoming radiation.
Two Y caps on the receptacle, so far this is average at best.
On the main PCB we get two inductors and two more Y caps. No X caps to be found. There’s a space marked off for an inductor AND an X cap, but they are vacant. I am disappointed. Typical PSU X caps cost $0.68 to $1 per single unit. If you buy 1000 of ’em that drops to $0.22 to $0.28, not much. I’d really like to see an X cap there. We do get a TVS diode though, that’s good.
Next in line is the LL25XB60 (25a, 600v) rectifier. If you’re thinking this looks familiar, it may be because it’s used in the 1350w Platimax as well. Might be just a touch overkill for a 600w PSU eh?
Two K20J60U (20a, 600v) MOSFETs for the APFC switches, combined with a CREE C3D06060 (6a, 600v) diode.
Primary capacitor by Panasonic.
Two more K20J60U (20a, 600v) MOSFETs for primary switches.
