Newegg PSU Wattage Calculator

Newegg PSU功率计算器

Intelligently collects component information through adaptive menus, then calculates total wattage via live Newegg CPU/GPU wattage tables + fixed tables.
scripts/calculate_psu.py
fetches the CPU and GPU wattage tables from the 
website-www-tool
endpoint (
apis.newegg.com/ex-mcp/...
, stateless JSON-RPC, no auth) and sends 
x-skill: newegg-psu-calculator
on every request. Nothing to install or register; if a fetch fails the script degrades to a warning in 
warnings[]
rather than guessing a wattage.
Core principle: Be smart about what to ask. If the user already mentioned components, skip those questions. Combine remaining unknowns into as few 
AskUserQuestion
calls as possible. Vary question wording based on context.
通过自适应菜单智能收集组件信息，随后结合实时Newegg CPU/GPU功耗表与固定功耗表计算总功耗。
scripts/calculate_psu.py
从
website-www-tool
端点（
apis.newegg.com/ex-mcp/...
，无状态JSON-RPC，无需认证）获取CPU和GPU功耗表，且每次请求都会发送
x-skill: newegg-psu-calculator
。无需安装或注册；若获取失败，脚本会在
warnings[]
中生成警告，而非猜测功耗值。
核心原则：合理设计提问内容。若用户已提及部分组件，则跳过对应问题。将剩余未知信息整合到尽可能少的
AskUserQuestion
调用中，并根据上下文调整提问措辞。

Phase 0 — Parse the user's message first

阶段0 — 先解析用户消息

Before asking anything, extract whatever components the user has already mentioned:
  • CPU model or brand → mark as known
  • GPU model or brand → mark as known
  • RAM size/type → mark as known
  • Storage config → mark as known
  • Any other component mention → note it
Then proceed to collect only the missing information.
Examples of smart extraction:
  • "I have a Ryzen 7 9800X3D and RTX 5080" → CPU ✓ GPU ✓, only ask RAM + storage
  • "I'm thinking about an RTX 4090, haven't decided on the rest" → GPU ✓, ask CPU + RAM + storage
  • "No idea what PSU I need" → ask everything
  • "i9-14900K + 64GB DDR5 + 2 SSDs" → CPU ✓ RAM ✓ SSD ✓, only ask GPU
在提问前，先提取用户已提及的所有组件信息：
  • CPU型号或品牌 → 标记为已知
  • GPU型号或品牌 → 标记为已知
  • 内存容量/类型 → 标记为已知
  • 存储配置 → 标记为已知
  • 其他组件提及 → 记录下来
之后仅收集缺失的信息。
智能提取示例：
  • "我有Ryzen 7 9800X3D和RTX 5080" → CPU ✓ GPU ✓，仅询问内存和存储
  • "我打算用RTX 4090，其他还没决定" → GPU ✓，询问CPU、内存和存储
  • "我不知道需要什么样的PSU" → 询问所有组件
  • "i9-14900K + 64GB DDR5 + 2块SSD" → CPU ✓ 内存 ✓ SSD ✓，仅询问GPU

Phase 1 — Collect unknowns via AskUserQuestion

阶段1 — 通过AskUserQuestion收集未知信息

Group missing components into at most 2 AskUserQuestion calls.
将缺失的组件分组为最多2次AskUserQuestion调用。

Grouping strategy

分组策略

  • Round A (core): CPU (if unknown) + GPU (if unknown)
  • Round B (peripherals): RAM + storage (if unknown)
  • If only 1 or 2 things are missing, combine them all into 1 call.
  • If everything is already known, skip directly to Phase 2.
  • 第一轮（核心组件）：CPU（若未知）+ GPU（若未知）
  • 第二轮（外设组件）：内存 + 存储（若未知）
  • 若仅缺失1-2项信息，将其整合为1次调用
  • 若所有信息均已知，直接跳过至阶段2

Adaptive question wording

自适应提问措辞

Vary the question text to match context — do NOT use the same fixed wording every time.
CPU question variants (pick the most fitting):
  • "Which CPU are you planning to use?" (general)
  • "You haven't decided on a CPU yet — pick one:" (when user said they haven't decided)
  • "What CPU?" (casual, when user is already in spec-listing mode)
  • "Besides [known components], which CPU are you going with?" (when some components are known)
GPU question variants:
  • "Which discrete GPU are you using?"
  • "Have you picked a GPU? Choose one:"
  • "What's your GPU?"
  • "Paired with [known CPU], which GPU are you planning?"
RAM question variants:
  • "How are you configuring your RAM?"
  • "How much RAM?"
  • "RAM capacity and generation?"
Storage question variants:
  • "What's your storage setup?"
  • "Storage configuration?"
  • "SSD only, or SSD + HDD?"
根据上下文调整提问文本——不要每次都使用固定措辞。
CPU提问变体（选择最贴合的表述）：
  • "你打算使用哪款CPU？"（通用）
  • "你还没确定CPU——请选择一款："（当用户表示尚未决定时）
  • "什么CPU？"（随意表述，适用于用户已在列出规格的场景）
  • "除了[已知组件]，你打算搭配哪款CPU？"（当部分组件已知时）
GPU提问变体：
  • "你使用的是哪款独立GPU？"
  • "你选好GPU了吗？请选择："
  • "你的GPU是什么？"
  • "搭配[已知CPU]，你打算用哪款GPU？"
内存提问变体：
  • "你的内存是如何配置的？"
  • "内存容量是多少？"
  • "内存容量和代数？"
存储提问变体：
  • "你的存储配置是什么？"
  • "存储配置情况？"
  • "仅SSD，还是SSD+HDD？"
