Plex Media Server installs on most current Asustor NAS devices via App Central in a few minutes, making Asustor one of the more cost-effective ways to run a Plex server compared to Synology at equivalent specs. By the end of this guide you will have Plex running, your media library scanned, and remote access configured on your Asustor NAS. Budget ARM models handle direct play reliably but do not transcode. Intel N5105 models such as the AS5402T and AS5404T support Plex hardware-accelerated transcoding for compatible formats with Plex Pass, delivering smooth multi-stream Plex performance at a lower price point than comparable Synology hardware.
In short: Install Plex from Asustor App Central, create a shared folder for your media in ADM, and enable hardware acceleration under Plex Settings - Transcoder if your model has an Intel N5105 CPU (Plex Pass required). Check whether your NBN connection uses CGNAT before relying on direct remote access from outside your network.
What You Need Before You Start
Plex Media Server's current App Central listing requires ADM 2.0 or later, although installing current ADM updates is recommended. ADM, or Asustor Data Master, is Asustor's operating system, which manages your NAS the way Windows manages a desktop PC. Check your ADM version in System - System Information and update if needed. Check that your exact NAS model appears in Plex Media Server's App Central support list; ASUSTOR does not state a 2GB RAM minimum. and a shared folder created for your media library before beginning the Plex setup.
Hardware transcoding in Plex requires a Plex Pass subscription. Without it, supported transcodes run in software on the CPU; capacity varies by model, codec, bitrate, resolution and subtitle requirements, and some low-power ARM NAS models cannot video-transcode at all. On Asustor, Intel N5105 models (AS5402T, AS5404T, AS6702T, AS6704T) support Intel Quick Sync hardware transcoding with Plex Pass. ARM-based models (AS3302T V2, AS1202T, AS1204T) do not support hardware transcoding regardless of Plex Pass status.
Step 1: Install Plex via App Central
Plex is available through App Central, Asustor's built-in application store. Open App Central from the ADM desktop, search for Plex Media Server, and click Install. If Plex does not appear in the default App Central search, check that your Asustor is connected to the internet and that App Central is pointing to the Asustor repository. The installation downloads and installs Plex automatically; completion time varies with connection speed and NAS load.
After installation, Plex starts automatically and listens on port 32400. Open Plex by clicking its icon in the ADM app launcher or by navigating to your NAS IP address followed by :32400/web in a browser on the same local network. Sign in with a free Plex account or create one at plex.tv, then complete the setup wizard to name your server and add your first media library.
Step 2: Set Up Your Media Library
Before adding a library in Plex, create a shared folder in ADM for your media files. Open ADM - Access Control - Shared Folders and add a new folder, for example named video or media. Set the Plex user account to have read access to this folder. Plex will not be able to scan media it cannot read due to ADM permission restrictions.
In the Plex setup wizard, click Add Library, select your media type (Movies, TV Shows, or Music), and point it to the shared folder you just created. Plex scans the folder and matches files against its metadata database, automatically pulling in cover art, plot summaries, and cast information. Initial scan time varies with library size, file organization, metadata matching and NAS performance, but matched titles become playable immediately.
Accurate file naming significantly improves Plex's metadata match rate. Movies should follow the format Title (Year).mkv, for example Interstellar (2014).mkv. TV shows work best with Series Name - S01E01 - Episode Title.mkv inside a folder named after the series. Files named with raw download strings such as movie.title.2014.1080p.bluray.x264.mkv often fail to match and require manual correction via Fix Incorrect Match in the Plex interface.
Step 3: Remote Access and NBN Considerations
Plex Relay can provide a 2Mbps indirect fallback when a direct connection cannot be established. Remote personal-video playback also requires an eligible Plex Pass or Remote Watch Pass arrangement on affected Plex apps. Once signed in to plex.tv, your server appears automatically in the Plex app on devices outside your network. Asustor NAS devices also support EZ Connect, Asustor's own remote management service, but for Plex specifically the Plex relay service is the more reliable path. For full remote access options including Tailscale VPN setup, see the complete Plex on NAS guide.
For a direct Plex connection from outside your network, forward port 32400 on your router to your Asustor NAS's local IP address. The complication for many Australian NBN users is CGNAT (Carrier-Grade NAT, a cost-saving measure some ISPs use that places multiple households behind a single shared public IP address). CGNAT blocks all inbound port forwarding, which means direct Plex access fails regardless of your router configuration. To check, compare the WAN IP in your router settings with the result from a public IP lookup site. If they differ, CGNAT is active. Contact your ISP to request a dedicated public IP, or use Tailscale to create a VPN tunnel that bypasses CGNAT.
Typical NBN 50 upload speeds average 18-20Mbps. A single 1080p Plex stream at original quality can require 8-20Mbps depending on the video bitrate. Lower remote video quality in the playback app; server-side bitrate limits under Plex Settings - Remote Access require Plex Pass. Households with multiple remote users should choose a plan based on its advertised upload speed and expected combined Plex bitrate, rather than the download-tier label alone.
Step 4: Enable Hardware Transcoding
Transcoding converts a video file from one format in real time so it plays on a device that cannot handle the original. Think of it like a live interpreter converting a conversation between two people who speak different languages: the NAS receives a file in one codec and delivers it in another, on the fly, without storing the converted version. Without hardware transcoding, this work runs on the CPU, and capacity varies with the processor, resolution, bitrate, codec and subtitle requirements.
Asustor NAS models with Intel Celeron N5105 CPUs, including the AS5402T and AS5404T, support Intel Quick Sync hardware transcoding. To enable it in Plex, go to Settings - Transcoder and turn on Use hardware acceleration when available. This setting only appears with an active Plex Pass subscription. Once enabled, each transcoded stream uses a fraction of the processor load compared to software mode, potentially allowing more simultaneous transcodes, with actual capacity depending on codec, bitrate, resolution, subtitles and HDR tone mapping. For a cross-brand hardware transcoding comparison, see the Plex hardware transcoding guide.
ARM-based Asustor models, including the AS3302T V2 and the AS1202T, use a Realtek RTD1619B processor that does not support hardware transcoding in Plex. These models work well for direct play, where Plex sends the original file untouched to a device that already supports the format. For households with a mix of devices that can and cannot direct-play, the step up to an N5105 model like the AS5402T from~$699 is well worth it.
Which Asustor NAS Suits Plex Best?
The right Asustor model for Plex depends on whether you need hardware transcoding and how many bays you want for media storage. Asustor's pricing advantage over Synology is most visible in the N5105 range: the AS5402T at~$699 is a capable 2-bay Plex server with hardware transcoding, compared to the Synology DS225+ at~$638 for broadly similar capabilities. For a detailed buying guide across all NAS brands, see the best NAS for Plex in Australia.
Asustor NAS for Plex: Model Comparison (AU Pricing 2026)
| AS3302T V2 | AS5402T | AS5404T | AS6804T | |
|---|---|---|---|---|
| CPU | Realtek RTD1619B | Intel Celeron N5105 | Intel Celeron N5105 | AMD Ryzen V3C14 |
| Default RAM | 2GB | 4GB | 4GB | 16GB |
| Drive bays | 2 | 2 | 4 | 4 |
| Plex HW transcoding | No | Yes (Intel QSV) | Yes (Intel QSV) | No |
| AU price from | ~$443 | ~$699 | ~$875 | $1,999 |
| Best for | Budget, direct play | 1-2 streams, compact | 2-4 streams, 4 bays | Heavy workloads |
For most Plex setups, the AS5404T from~$875 is the practical pick. It provides 4 bays for a growing media library, Intel Quick Sync hardware transcoding for Plex Pass subscribers, and default 4GB RAM that handles Plex plus background tasks without issue. The AS5402T at~$699 covers 1-2 stream setups in a 2-bay enclosure and is the best-value entry into Asustor Plex with hardware transcoding. The AS3302T V2 from~$443 suits budget-conscious buyers whose devices primarily direct-play, avoiding the need for transcoding altogether. The AS6804T from~$443 is aimed at high-demand setups with its AMD Ryzen CPU and 16GB RAM, but most home Plex users will not need that level of hardware.
Asustor vs Synology for Plex
For a Plex-focused NAS, Asustor delivers the same media server experience as Synology at a lower price. Plex itself is identical on both platforms. The AS5402T supports Intel Quick Sync hardware transcoding in Plex. Do not assume equivalent out-of-box behaviour from the DS225+: current DSM does not enable its iGPU driver by default, so native Plex hardware transcoding requires an unofficial workaround. The price difference buys you Synology's more polished DSM operating system and its broader software ecosystem, but those features are largely irrelevant if Plex is your primary use case.
Where Synology pulls ahead is in software depth: DSM is more feature-rich, Hyper Backup is a more capable backup application than Asustor's equivalent, and Synology's app catalogue covers more advanced use cases. If you expect to expand beyond Plex into serious backup, virtualisation, or Docker workloads, Synology's more mature ecosystem is the better long-term investment. If Plex is the primary goal and storage costs matter, Asustor is the rational choice. Asustor currently lists Dicker Data as its Australian distributor, which means stock depth is more variable than Synology, where two well-resourced distributors (BlueChip and MMT) cover the market.
Troubleshooting Common Plex Issues on Asustor
If Plex is not visible after installation, confirm it is running in App Central (check the installed apps list and status). Asustor NAS devices occasionally require a manual Plex service restart after ADM updates. From App Central, click the Plex icon and select Stop, then Start. If the issue persists, confirm that ADM's firewall allows traffic on port 32400 under Settings - ADM Defender - Firewall.
For local stream buffering, open the Plex web app Now Playing view and check the quality label. If it shows Converting, the client requires transcoding. On N5105 models with Plex Pass, confirm hardware acceleration is enabled under Plex Settings - Transcoder. If buffering persists with hardware acceleration active, check ADM Resource Monitor for CPU or RAM pressure from other running applications. Scheduling intensive tasks like backups for overnight hours reduces competition for resources during active Plex usage.

Does Plex support hardware transcoding on the Asustor AS5402T?
Yes. The AS5402T uses an Intel Celeron N5105 processor that supports Intel Quick Sync hardware transcoding in Plex. You need an active Plex Pass subscription to enable it under Settings - Transcoder. With hardware transcoding active, the AS5402T can support multiple transcodes, but the exact number depends on codec, bitrate, resolution, subtitles and HDR tone mapping. AS5402T pricing changes frequently; check current listings at CPL, Scorptec and PLE before publication.
Does Plex work on the Asustor AS3302T V2?
Yes, Plex installs and runs on the AS3302T V2 via App Central. The AS3302T V2 uses a Realtek RTD1619B ARM processor that does not support hardware transcoding. It handles direct play well for devices that natively support your video formats, but transcoding performance is limited. The AS3302T V2 is available from $352 and is a cost-effective entry point if your devices can direct-play your media files.
Is Asustor a good NAS for Plex compared to Synology?
Yes, for Plex specifically. The media server experience is functionally identical on both platforms. Pricing varies by model, retailer and promotion; compare current delivered prices and confirmed out-of-box Plex hardware-transcoding support for each NAS. Synology's advantage is its broader software ecosystem (DSM, Hyper Backup, Active Backup) which matters if you plan to use the NAS for more than Plex. For a Plex-first setup, Asustor offers strong value.
How many Plex streams can an Asustor NAS handle?
The AS5404T supports Intel Quick Sync hardware transcoding, but simultaneous-stream capacity varies with codec, bitrate, resolution, subtitles and HDR tone mapping. Do not assume an ARM model can complete even one video transcode; plan for Direct Play unless the exact NAS and media profile have been verified. Direct play streams are far less demanding, and even the AS3302T V2 can serve multiple direct play connections simultaneously without strain.
Where can I buy an Asustor NAS in Australia?
Asustor NAS devices are available at Scorptec, PLE, Computer Alliance, UMart, MSY, and Centre Com. Asustor currently lists Dicker Data as its Australian distributor, which means stock depth can vary by retailer and model compared to Synology. Australian Consumer Law protections apply when purchasing from Australian authorised retailers. For Australian Consumer Law remedies, contact the retailer; any separate manufacturer-warranty process depends on the applicable warranty terms.
Does CGNAT affect Plex remote access on Asustor?
Yes. CGNAT (Carrier-Grade NAT) prevents inbound port forwarding, which blocks direct Plex remote connections regardless of your NAS brand or router settings. Plex's relay service still works under CGNAT but may limit bandwidth. To check for CGNAT, compare your router's WAN IP against your public IP at a lookup site. If they differ, CGNAT is active. Contact your ISP to request a public IP address, or use Tailscale to create a VPN tunnel that routes Plex traffic around CGNAT.
Asustor is one of the most cost-effective ways to run Plex, but choosing the right model and storage configuration matters. The complete Plex on NAS guide covers every step from hardware selection to multi-user remote access across Synology, QNAP and Asustor.
