THIS 25GbE Server and Firewall Has it All

That is SpecTek RAM. SpecTek is a Micron subsidiary that does binning of NAND and DRAM ICs. You will generally only see their logo on low binned ICs. That doesn't mean it's not tested to work, just that it's rated for a lower speed and/or higher voltage then something Micron wants their name on.

The 150W PSU is probably to ensure it can deliver all its functionality at once. Your benchmarks showed that it was already using ~51W under load, which looked like it was with none of the front I/O populated. If we add 15W for PoE, dual 10GBaseT SFPs at 3W apiece, USBs in all four ports taking 4.5W apiece, we're already looking at ~90W without adding in populating both SATA and M.2 slots and some potential extra load for populating the 1G and 2.5G ethernet. That's also not taking into account AC-DC conversion on all those wattages, which are wattage at the device, 100W wouldn't be enough for the system fully loaded.

I love that GoWin asks their customers for feedback, actually listens to that feedback, and makes real changes in their products in response to those recommendations. In this day and age that's insane. Awesome!

Nice. The i3-N305 version is only 700 dollars. That is a very nice price for the performance and connectivity. Since they didn't include it in this review on description, the actual model number is: GW-BS-1UR2-25G

This and the 1U 4x SFP+ Qotom have me seriously considering trying one of these devices. And I can understand the POE port, makes it easy to slap a POE AP and keep it a low power device.

You also have to keep the efficiency curve of the PSU in mind. For a system that could go up to 100W with all components under load, a 150W PSU is reasonable. I'd probably still swap the fan for a Noctua for reliability alone.

POE is awesome for 5G, there are some outdoor 5G Modems that are POE powered.

They REALLY should have taken a design hint from old stereo equipment for the 'fanless' unit. Put the heatsinks on the back and/or sides, so air can rise through the fins with convection. Further, I have decided the ideal way to quietly cool a 1U chassis is with a blower fan ~2/3U thick. Plop it in there flat, blowing at your parts, Sucking in air from the 'top' which has room because it isn't as thick as 1U. Route the intake to a slot in the front. They can be quiet by running at a lower RPM and still push a lot of air. They just take up a bigger internal footprint. So not ideal for maximum density servers where everything is LEGO tight. For switches and systems like this one with big empty spaces in them it's great though.

I ordered one of these 2 days ago, waiting for it to arrive. This video came out right when i was looking for more info about it, great timing. Just my luck that they come out with a fan-less version a couple days later..

Dang they really went out of their way to send you units easy for you to review. Great on them!

I think having the POE port is a good idea. Let's you run a poe powered AP. So if you set this up a do it all machine, it's one less piece of equipment you need.

I think the 1gb Poe port is to run a 5g WWAN router, powered off the main firewall for redundant or backup internet. I think that's pretty cool!

i wish they made the fins parallel to the possible airflow in the rack. if there are other devices in the rank that has a fan i think it'd benefit from the residual airflow they produce. but if you already have a noisy server then a fanless unit wouldn't make that much sense... food for thought.

Been waiting for this review. Gonna pick one of the 10G versions up to try as a worker node in my home k8 cluster.

5:32 "There are 6 lights!" :D

I am quite surprised they're not using a Pico ATX PSU in there. You can get up to 250W in a tiny fanless package, and I don't think you'd need any more than that. That would mean you have a power brick to convert the AC to the 19v DC input, but a PicoATX is so small you'd have the space to include that inside the case, where the existing PSU was.

The POE port is a great idea in my opinion. One great use could be to have a backup connection with POE powered 5G/longrange Wifi antena from ISP etc. Great way to have acess to the devices remotly in case needed. Yeah the antena can be mounted inside the chasis but the reception is not always best in places where server racks are placed from my experience

There are two asm1806 chips on the board. They only support pcie 2.0. Would be interesting how the Lanes are shared.

a good step in the right direction, but it needs a powered sata/usb DOM header for it to be useful. props to gowin for trying out new things!

Etched/covered/marked off labels usually indicates counterfeits or import/export illegalities. Though that example was exceptionally lackluster.
