Now that we’ve got all the hard part taken care of let’s split us a seal.
Popping the hood we find that the layout is very clean inside this big monster. Look at the size of the choke on the primary side, it’s huge! The choke takes up as much if not more space than the two Teapo primary caps. The 12V rail has not one but two transformers. I’ll go into this in a bit greater depth in a bit but let’s move on after just enjoying the view.
Remember I said that the X3 was based on a server platform? It’s built on the AD800 platform. Yes, that’s right it’s based on an 800W unit. I spoke to Jon about this and he got with the fellows at Ultra and their answer to Jon was that they’ve essentially stuffed a big block in a small block chassis (no joke, that’s the analogy they used) so I don’t know how for sure but they did manage to pull a couple hundred more watts from the design.
One interesting thing I noticed with the X3 is that they used two bridging rectifiers feeding the DC to the secondary side. Not only that but Andyson wisely chose to tie them together on the same heatsink and then married that heatsink into the main heatsink for the primary MOSFETs. This adds a whole lot of radiating area for the heat from those rectifiers without adding a lot of mechanical complexity to the unit.
The 12V is split up into four rails inside the PSU but it obviously doesn’t stay that way. we’ll see how it becomes a single rail in a bit. Also worth noting are the mongo wires running up to the modular interface. 14AWG baby! Sharp eyed readers will note that the secondary caps are also Teapo at least I’m assuming that they are…
Look at the size of that primary choke…yowza!
I saw something I thought was interesting… look at the MOSFET in the upper center of this pic, did you use enough thermal paste guys? ROFL! It’s all over the place.
Taking a look at the back of the modular interface I notice that the solder is a bit on the clumpy side. At least there aren’t any solder bridges shorting out rails. I would like to see things cleaned up though.
Here we see how the four 12V rails merge into a single rail. It all ties together on the modular interface.
Heh, at least the primary side MOSFETs aren’t dunked in thermal paste. 😉
I’d sure like to know what parts are used in the AD800 so I could compare them. I know that the 12V transformers share the same numbers but that just proves that they have plenty of guts in the AD800 to potentially push 1KW. I’d like to know what the FETs are and the rectifiers ETC from both units just so I could see what was tweaked to pull that extra wattage out of it.
I can’t get over how well packed the X3 is yet it’s still very open inside. This means that the 135mm fan has no trouble pushing air through it.
