ASRock Motherboard & CPU Combo Motherboards J3455-ITX

A nice fan-less ITX board. Only issue with the board is that it doesn't seem to like my SeaWit KVM - it seems to hang for a while on the Press F2 to setup screen with it connected. It does eventually time out, but then it doesn't respond to the keyboard or mouse after that. It works fine when I directly connect the keyboard and mouse.

I had an old Ubuntu linux system that died, and I replaced the motherboard with this (J3455-ITX, plus 1 new stick of RAM). This one is nice, because it has almost everything on the board, so I don't need a bunch of extra cards for LAN/video/audio (yeah, I haven't bought a MB in a while). There was 1 setting I had to change in the BIOS so it would boot the older SATA HDD, and I was up and running in about 30 minutes for the swap. No fans, so it is very quiet, and it runs cool. All the noise comes from the HDD and the PSU, now. Could easily make this dead silent with a fanless PSU and SSD. Total power consumption is around 30W for the entire system, measured with a Kill-A-Watt. Without the tuner card, it would probably be closer to 20W. For how I use this (DVR in the backroom), it works perfectly.

Easy installation in windows 10. The board works really good. It's is not a speed demon, but it gets the job done. For a Home Theater PC is excellent. It has all the necessary ports. The included video in the processor can decode h265 in Kodi.

Got as a gift for husband and he loved it came in the mail fast and undamaged will be ordering more here soon

Board EFI is unreliable. It may stuck and require reboot when you are doing initial configuration. Same behavior after upgrade to latest 1.20 firmware. Board works well with Ubuntu 16.04 LTS. 16.10 is also ok if you are not going to use virtual machines. Intel VT-d is supported and you may wish enable and configure linux kernel with intel_iommu=on parameter. Such config works ONLY if you disable integrated ASMedia ASM1061 controller, otherwise board will stuck randomly within first 1-3 minutes. Until you need to passthrough PCIe slot to a guest, leave VT-d disabled. After 15 minutes of demo BD playback (mini ITX enclosure), CPU temperature maxed and stopped at 130 °F. No additional fans are required. Embedded quiet fan control feature does not work! It runs fan despite of configured target CPU temperature.

I realize AsRock is Asus' budget line, but come on guys. 2 out of 2 AsRock itx boards DOA. I'm not waiting for a 3rd strike. I'm going back to an I5 9400 on an Asus Prime HT10. Yeah, 3 times the price over all, but you get what you pay for.

First one was DOA. The final three worked the first time and continue to give me peace of mind. Extremely reliable and high quality devices compared to those other lower tiers boards from parts unknown that are DOA or don"t even POST.

This isn't a 2.3GHz CPU, it's an "Intel(R) Celeron(R) CPU J3455 @ 1.50GHz". I also have discovered with Linux every boot there are Machine Check Exceptions for errors, while they don't seem to affect anything it's annoying every bootup. Yes, already checked for newer BIOS and there was none, and it passes all memory and other diagnostics I can think of so I don't think it's DoA. Fortunately I'm only needing this to run a low power file-server for relatives and can cope with the lower performance and annoying "errors" but it certainly leaves me wanting to avoid ASRock Motherboards for future builds. I regret not getting a Gigabyte or SuperMicro which I've had much better success with.

2025.07.29に注文し、2025.08.12に受取りました。 mini-ITX、SATAx4、オンボードCPU、安価 という条件で探していましたが、 入手できて良かったです。 少し日数がかかりましたが、輸送状況のメールが 2度届き安心して待つことができました。 現在、順調に稼働しています。 ありがとうございました。

Die Lieferung des ordentlich verpackten Mainboards J3455-ITX über UPS verlief pünktlich im annoncierten Zeitfenster. Die Inbetriebnahme des Mainboards mit einem zusätzlichen PCIe2-SATA-Controllers (4xSATA) aus meinem Bestand auf dem einzigen PCIe-Steckplatz des Mainboards unter Ubuntu 18.04 LTS-Server (ohne graphische Oberfläche) lief problemlos durch. Die Stromversorgung habe ich mit einem Pico-PSU-Adapter 90 Watt in Verbindung mit einem externen 12-Volt-Netzteil umgesetzt, da in dem kleinen PC-Gehäuse bereits 4 NAS-HD von WD mit jeweils 3 TByte in herausnehmbaren Schnelleinschüben zu verbauen waren. Da passte wirklich kein Standard-ATD-Netzteil mehr rein. Die Kriterien für ein NAS für mich: Geringe Leistungsaufnahme, Energiesparmodi des Betriebssystems funktionieren reibungslos, Wake-on-Lan mit MagicPacket muss reibungslos funktionieren. Alle Kriterien erfüllt das J3455-Mainboard problemlos. Die Leistungsaufnahme des NAS mit besagten 4 x 3TByte-WD-NAS-Festplatten, 1 x SSD für Betriebssystem liegt im Leerlauf (ohne Hibernate/Suspend) bei 32 Watt. Die Datenübertragungsraten sind unspektakulär, die 1 Gbit Netzwerkkarte liefert beim Transfer über das Netzwerk solide 70 MByte/Sekunde ab. Über die internen SATA-Schnittstellen wird es nicht schneller, die WD-NAS-Platten sind halt keine Sprinter im Software-RAID 1 unter Ubuntu 18.04 LTS-Server. Dass der M2-Steckplatz nur für Wifi geeignet ist, hatte ich der Beschreibung vorab entnommen. Gut ausgegebenes Geld, sach' ich mal ganz entspannt. Mal sehen, wie sich das J3455-ITX-Mainboard im Betrieb verhält. Der digitale übergroße Fußabdruck des kurz zuvor "abgerauchten" ITX-Boards von Jetway setzt eine Referenz. Das Jetway-Board hat solide 12 jahre unauffällig und höchst zuverlässig vor sich hin gewerkelt.

This is a nice efficient board. I had some difficulty with installing Opensuse Linux on it, but when I switched to Kbuntu everything worked fine.

Adquirí esta placa para sustituir a la difunta Q1900ITX de la misma marca, ASROCK. En un principio estaba muy duditativo, debido a los problemas que me estaba dando la Q1900ITX. Además tras leer tanta opinión negativa, me lo pensé muchísimo. Luego Amazon me envió una que estaba abierta, no sé si usada o no, pero nueva nueva no era. Tras llegar a un pequeño acuerdo, y la ver que parecía que estaba todo en orden, procedí a quedármela y probarla en mi HTPC. Esta placa no da para juegos, ni para operaciones que requieran potencia, pero el uso que le doy como centro multimedia del hogar y de nube personal, es perfecto. No consume casi nada, al llevar disipador pasivo, no hace ruido alguno, no sube de temperatura casi nada, y para Kodi, ver películas, uso como nube, etc, va genial. Solo tener en cuenta que tendréis que tener Windows 10, ya que con W8, W7 o inferiores, no hay drivers compatibles, aunque ponga que si sirven, luego a la hora de la verdad, solo funciona bien en Windows 10.

Excellent little board, being used as HTPC to replace my older Acer Revo small form factor PC. Acer was beginning to struggle with online streaming (would sometime noticibly 'jump' a frame. This board is much more powerful, no skips at all. Had some laptop memory and an Antec ISK 310-150 case already so easy swap over. Silky smooth movies streaming and good enough as everyday tasks like browsing, office work etc. Better than expected, would buy again as a desktop machine, network server etc.
