What Power Supply Do I Need for Starlink Standard 4?</h1>
<!-- 核心答案（Featured Snippet 优化：开门见山） --> <p style="font-size:16px; margin-bottom:20px;">
<strong>Short answer:</strong><br />
You need Starlink Standard 4's proprietary <strong>57V PoE power supply</strong> (model <strong>UTP-253L</strong>). It takes <strong>100–240V AC, 2.5A, 50/60Hz</strong> input and outputs <strong>57V DC via PoE</strong>, with a <strong>maximum total output of 195W</strong> (the dish itself operates at approximately <strong>56V DC</strong>).<br />
Average system power consumption is <strong>75–100W</strong>. A standard 48V PoE injector will <strong>not</strong> work.</p>

Critical: Why 57V — Not Standard 48V PoE</h2>
<p style="font-size:15px; margin-bottom:16px;">
Many users assume Starlink works with off-the-shelf <strong>48V IEEE 802.3af/at PoE</strong> injectors. It does <strong>not</strong>. Starlink Standard 4 requires a <strong>56–57V DC</strong> proprietary PoE feed with sufficient current (>3A).<br />
Using a 48V injector will cause the dish to fail to boot, reboot randomly, or run unstable — especially during cold-weather <strong>snow-melt</strong> (heating) mode when power demand spikes.</p>
<!-- 功率预算 --> <h2 style="font-size:20px; color:#004b98; margin-top:28px; margin-bottom:12px;">
Power Budget & UPS Sizing Note</h2>
<p style="font-size:15px; margin-bottom:16px;">
Although the dish averages only <strong>75–100W</strong>, the original supply is rated <strong>195W</strong> to handle startup transients, long cable runs, and snow-melt peaks.<br />
When selecting a replacement adapter or UPS, <strong>size for the peak, not the average</strong> — plan a minimum of <strong>120W load budget</strong> for dish-only backup, and <strong>140–180W</strong> if also backing up a router/switch.<br />
Never size a UPS solely on the 75–100W average.</p>

<br />
Standard 4 vs. Standard 4 X — Power Difference</h2>
<p style="font-size:15px; margin-bottom:16px;">
<strong>Starlink Standard 4</strong> (with Router Mini) uses the new <strong>195W PoE brick (UTP-253L)</strong> and lets you connect a third-party router directly to the PoE port without needing the Starlink router. <strong>Starlink Standard 4 X</strong> (previously Gen 3, with Router 3) uses a different proprietary supply rated around <strong>150W</strong> and binds power delivery to Router 3.<br />
Always match the power supply to your exact kit generation.</p>

Compatible & Off-Grid Power Options</h2>
<ul style="font-size:15px; margin-bottom:24px; padding-left:20px;">
<li>
<strong>AC Replacement:</strong> 57V DC, ≥195W (e.g. 57V/3.42A or 57V/4A), input 100–240V AC, IP66-rated DC plug.</li>
<li>
<strong>Official DC-DC (off-grid/RV/solar):</strong> Starlink Standard DC-DC Power Supply — <strong>12–48V DC input</strong>, <strong>56V / 3.57A output</strong> (~200W), <strong>XT60</strong> connector, 12AWG, IP66.</li>
<li>
<strong>Third-party router integration:</strong> With Standard 4's PoE brick, simply connect your own router to the second RJ45 port — no bypass mode required.</li>
</ul>
