In my latest project, I assembled a budget-friendly, power-sipping home theater PC (HTPC) using AMD's innovative AM1 platform. This setup runs Ubuntu as an efficient media center—details on the build here. Now, I'm giving one away. Read on for the full story.
At the core of the AM1 platform is APU technology, integrating CPU and GPU into one chip. This design shrinks space requirements and overhead compared to traditional Intel or AMD processors. With lower power draw, it pairs perfectly with picoPSUs, converting 96% of wall power to usable energy. It excels as a desktop, HTPC, or even light Steam machine at console resolutions.
That said, DIY builders must understand AM1's nuances, especially its integrated graphics (APUs). A modern media center shines by delivering content to your TV seamlessly. By consolidating components into the APU, AM1 enables ultra-affordable motherboards starting at $29.99. Power use hovers around 30W in normal operation—ideal for media playback, office tasks, and more.
This guide details key components with pro tips for an AM1-based media center or productivity rig, plus three real-world sample builds I've tested.
The AM1 platform shines in compact, efficient setups but has limits: small form factors, few SATA ports, and spotty driver support.
AM1 boards are mini-ITX (mITX) or micro-ATX (mATX). The main difference? PCIe slots. mITX offers one PCIe 2.0 x16 (quarter speed); mATX adds another PCIe slot plus the x16.
A quarter-speed PCIe 2.0 x16 is wired for x16 but runs slower.
mITX single PCIe 2.0 x16 (quarter speed):
mATX PCIe + PCIe 2.0 x16 (quarter speed):
Standard AM1 boards have two SATA III ports—enough for most HTPCs. File servers need more, but small cases limit drives anyway. Some boards add SATA via controllers with poor Linux support. For Linux reliability, stick to basic two-port boards. Windows 7 had issues on some; Windows 8 works better.
Out-of-box compatibility favors recent Linux kernels (e.g., Ubuntu 14.04 Trusty Tahr upgrade guide) or Windows 8. Older Windows needs extra drivers, often unsupported. Linux APU drivers lag Windows but AMD offers proprietary ones. Linux open-source drivers may stutter on HD video; proprietary f/ Catalyst improves it.
Basic PC-building knowledge applies (see our PC build guide). Here's what sets AM1 apart.
As of May 2014, six AM1 APUs blend CPU/GPU for lower power and space vs. discrete cards. They borrow system RAM (512MB-2GB); faster RAM boosts gaming.
RAM: No dual-channel support; max 1600MHz DDR3. A single 4GB stick works great.
Swappable APUs: All 25W TDP, socketed for upgrades (AM1+ compatible).
mITX or mATX; ~12 models, $30-$60. Extra features (SATA, mini-PCIe) risk Linux issues.
mITX preferred for tiny cases; discrete GPUs disable iGPU anyway.
Ensure 65mm cooler clearance. picoPSU-integrated: Realan E-i5 (2x 2.5" bays), E-i7 (slim DVD). 60W for SSDs; upgrade for HDDs (25W spin-up).
mITX cases:
mATX:
picoPSU best for SFF; TFX/SFX noisier. Match connectors or add adapters.
Air Mouse: Gyro-based for cursor control—my top pick.
IR Remotes: Need receiver; universal TV/PC control, no WiFi lag.
Dual-Band WiFi: Cuts interference for streaming (dual-band guide).
Standard PC assembly; AM1 socket (FS1b-like) uses guide posts for cooler install. Align, press pins to lock.
Load defaults, set RAM profile/APU allocation. For Linux, CSM to "Other OS".
Ultra-budget Linux HTPC, deluxe Linux mini-ITX, eco Windows 8 all-rounder.
Upgrade to quad-core 3850 for better GPU. Low power despite active PSU.
Stylish, portable, handles DVD, emulation, light gaming—no Blu-ray bloat.
15-25W idles; Windows/SSD/low-voltage tweaks maximize efficiency (SSD guide).
From my builds, AM1 nails Linux compatibility, efficiency, and value. Craft a stellar Ubuntu HTPC under $200—or $400 with Windows. Perfect for media or productivity.
