As always, we’ll start out with a fan shot. As was the case with the 850W model, Globe Fan is our supplier of wind.

Now, as I said before, I’ll do something I never do and take it apart. Why don’t I do this? Two reasons… it takes a LOT of time and often renders the fan useless. Then I have to find another fan before the power supply can be used again. It’s a massive pain in the neck I am only too happy to avoid on most units. We’ll start by peeling off that label.

Under the label, I found… another label with the letters “TNB” on it, presumably for sealing in the lubricant. Looks like the fan might actually have been sourced from Jetmotor through Globe… or something. Let’s peel off this label, too.

Ah yes, that’s a normal enough looking lubrication well, there. A single nylon washer clips the fan blades on, so I’ll just pop that off now and remove the blades.

And there you go. Fan blades.

Here’s where I’ll stop on this. I could go a bit further, but I’m determined to at least try and get this fan to work again. It’s basically a special sleeve bearing fan, and with what I see here combined with the literature EVGA sent me I’m satisfied this isn’t your normal “dies in a month” sleeve bearing job.

I won’t score against this. Rather, I’ll go get a ball bearing fan out of another power supply and swap that one into the unit instead. This one will be re-assembled and used to cool a mining rig or something.

Now… because taking the fan apart took a bunch of time off the table, we’re going to breeze through the rest of this page. We’re not going to see anything we haven’t seen already.

Hello, Seasonic!

Here’s where we’d find some line filtering components if I were to take this off. Seasonic’s pretty consistent with this platform, so take a look at the 850 GS review if you want to actually see inside here. I’m not taking the extra time today.

Soldering in this unit is top notch. Seasonic sometimes slips up, but this is not one of those times.

I count two coils, two Y caps, two X caps, and a TVS diode. The line filtering is more than adequate, combined with the parts found on the AC input board we didn’t look at this time.

Four 5R399Ps make up the main switchers.

Protection has been brought to us today by Weltrend.

Here we find two Hitachi main filter caps to the left of the PFC parts, one diode, and two 6R125Ps.

Once more, Seasonic has decided not to use thermal grease on the two parts of the 12V output sink. Clearly, they don’t feel it’s necessary, but I’m already in here so I’ll just add some. Won’t hurt a thing. That’s a CM6901 on the board nearby.

All secondary capacitors are either Chemi-Con or Nichicon. Complaints, I have none. The glue guy could have used a bit more restraint, though.

The VRM uses an APW7159 controller and six 0906NS parts to supply the 3.3V and 5V outputs.

Lastly, I have no complaints here, either. Time for the score!
