In practice that means specifying <strong>sustained<\/strong> (not peak) wattage, a PD 3.1 EPR-capable design, an e-marked 5A cable, and an adapter that still clears DOE Level VI and EU ErP efficiency at that load. Paiyi Power builds and tests AI PC power supply OEM programs to exactly those four constraints.<\/p>\n<hr>\n<figure style=\"width: 768px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-large wp-image-1082\" src=\"https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test.webp\" alt=\"AI PC power supply OEM: ATE functional test of a high-wattage USB-C AI PC power adapter at Paiyi Power\" width=\"768\" height=\"576\" srcset=\"https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test.webp 1600w, https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test-300x225.webp 300w, https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test-1024x768.webp 1024w, https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test-768x576.webp 768w, https:\/\/www.paiyipower.com\/wp-content\/uploads\/2026\/09\/pyi-factory-ate-test-1536x1152.webp 1536w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption class=\"wp-caption-text\">Every adapter is functionally tested on ATE before it leaves the line<\/figcaption><\/figure>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"why-ai-pcs-draw-power-differently\">Why AI PCs draw power differently<\/h2>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">Sustained load, not short peaks<\/h3>\n<p>A conventional laptop adapter is sized for bursty work: the CPU spikes, then idles. The adapter cools down between spikes, so a supply rated just above the average draw works fine. An AI workload behaves differently. Local inference, real-time transcription, and background assistant features hold the silicon at a high fraction of its power budget for minutes rather than milliseconds. The adapter therefore sees a near-continuous load, which is a far harsher duty cycle than the same average wattage delivered in bursts.<\/p>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">The NPU adds a third sustained consumer<\/h3>\n<p>AI PCs add a neural processing unit alongside the CPU and GPU. Even when the NPU itself is efficient per operation, it is one more block drawing power at the same time as the CPU and GPU. The practical effect is a higher <em>floor<\/em>: the machine rarely drops into the low-power state that let older adapters recover thermally.<\/p>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">What this does to the thermal budget<\/h3>\n<p>Heat is the real constraint. A 140W adapter that must deliver 140W continuously needs a thermal design sized for steady-state, not for a 30-second benchmark. That is why two adapters with the same nameplate wattage can behave very differently under an AI workload: one derates after ten minutes, the other holds. When you brief an AI PC power supply OEM, ask for the continuous-output figure and the derating curve, not just the peak rating on the label.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"how-much-wattage-an-ai-pc-actually-needs\">How much wattage an AI PC actually needs<\/h2>\n<p>Use the table below as a starting brief.

At 5A that is 100W, which is why 100W became the ceiling for so long. <strong>USB PD 3.1<\/strong> introduced the Extended Power Range with 28V, 36V and 48V levels at up to 5A, which is where 140W (28V\/5A) and 240W (48V\/5A) come from. Any AI PC adapter above 100W is an EPR design; there is no way to reach 140W inside the old 20V limit.

Letting the charger track the load more closely cuts conversion loss and heat &#8212; useful on a 65W&#8211;100W AI laptop that spends most of its time just below full draw. It is an efficiency feature rather than a power increase.

Certification status is per-model and per-batch, and earlier production runs were tested and certified to USB PD 3.1. We send the model-specific report rather than a blanket claim, because a blanket &#8220;PD 3.2 certified&#8221; statement is not something a serious brand can put in a filing.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"cable-and-connector-where-high-wattage-programs-fail\">Cable and connector: where high-wattage programs fail<\/h2>\n<p>This is the most common field failure in AI PC launches and it is not the adapter&#8217;s fault. Above 3A, a USB-C cable must carry an e-marker chip that tells the source what current it can handle. Above 20V, the cable must be rated for EPR voltages. Put a 140W adapter behind a 3A cable and the system silently negotiates down to 60W; the user reports &#8220;charger too slow&#8221; and returns a perfectly good adapter.<\/p>\n<ul>\n<li><strong>Up to 60W:<\/strong> any compliant USB-C cable (3A).<\/li>\n<li><strong>Up to 100W:<\/strong> 5A e-marked cable (20V\/5A).<\/li>\n<li><strong>140W&#8211;240W:<\/strong> 5A EPR e-marked cable rated for 50V.<\/li>\n<li><strong>In the box:<\/strong> bundle the correct cable, and print the rating on it.

On an AI workload that point arrives quickly. Two questions separate a credible AI PC power supply OEM from a catalogue reseller:<\/p>\n<ol>\n<li><strong>What is the continuous output at 40&#176;C ambient?<\/strong> Not the peak, not the 25&#176;C lab figure.<\/li>\n<li><strong>Where does derating start?<\/strong> A reputable supplier will show you the curve.<\/li>\n<\/ol>\n<p>GaN helps here. Because a GaN switch wastes less energy as heat, more of the thermal budget goes to sustaining output rather than to surviving it. That is why most compact 140W designs are GaN.
