The exhaust grille on this unit shows us the same scenery as the 1kW model. That big coil you see behind the mesh is part of the line filtering on this unit to help reduce EMI.

The specifications of this unit are pretty much identical to big brother, save for the maximum output power the 12V rail, and by extension, the entire unit is capable of putting out.

You better believe I’ll be putting that fifty degrees at full power number to the test later on, too. I can’t wait… that’s why I’m speeding through the first two pages of this review like I have Ferraris for fingers. Although, I reckon that would actually make me type slower, now that I think about it.

There are some differences with the modular connector panel on this unit compared to the 1kW model, but the differences are minor. We have two fewer PCI-E cable connectors on this one, with the connectors arranged in two rows vs. three. There is also one less peripheral connector.

And yes, you can still use the SATA and Molex in any of those six pin connectors. They do interchange, and they are electrically compatible. No, you cannot interchange the VGA and CPU cables – the unit won’t let you because they are not electrically compatible.

EVGA really needs to get away from this stamped steel nonsense on the flagship model units, I think. Although this unit is just as likely to run fanless most of the time as its big brother, once the fan is moving this grill will make it louder than a traditional wire grille would.

Make sure you remove the clear plastic over the center hub if you really want the full “ooh, shiny” factor from it. I’ve removed it for this shot.

Cable time! The cables of this unit are similar and yet different from the 1kW model. The differences amount to lengths only.

All but the peripheral cables have those in cable capacitors as well, and I would like to point out that OEMs like Delta and Seasonic don’t need those to get good results on the scope later. It’s been suggested that I should start pulling points for this issue, because it does hinder cable management a little bit, but I’m not sure I’m fully on board with that idea yet. The score is my own personal opinion, and I’m not sure I find them that big of a deal just now.

With that said, I’ll be using this very unit in my main rig starting this week, if all goes well. If the capacitors get in the way, I’ll probably tweak my scoring methodology as a result. We shall see.

Once more, we get a selection of single PCI-E and dual PCI-E cables. You can power up to six PCI-E connectors at any one time, though only four of them can be eight pin. That should be plenty for an 850W unit.

This is one of three SATA cables that come with the unit. Again, similar to the 1kW model but with one fewer connector per cable save for one that has four. Ten in total, which is plenty.

The 1kW model had two Molex chains… this unit only has one. And hallelujah, the only Berg connector is off on its own adapter.

Now… let’s do something I haven’t done yet. Let’s butcher a PCI-E cable and take a look at one of those capacitors. People have been curious about these, and so have I. I can’t always do this, so don’t get too used to it, but I’ll do it just this once.

There you have it – the capacitors are Nippon Chemi-Con polymers. Better quality than I was expecting. Sweet! Whether or not they’re a functionality drawback, at least they’re excellent quality. Not that quality matters, here. General purpose electrolytic parts would have likely done the job with no impact on reliability. It’s not like these will ever be subjected to anything close to the 85 degrees even the low-end stuff can handle.

Again, the cables are different from the 1kW in length only. The CPU cables and PCI-E cables are shorter, but not so short that I think they need to be scored against.

You know what time it is now, right? Load testing time. Let’s get to the next page and hurry up!
