<p dir="auto">振华850W带7900XTX跑ComfyUI是够用的，但要看具体型号。7900XTX的典型游戏功耗在355W左右，ComfyUI生图时GPU持续满载，加上CPU（假设是普通消费级）和主板、硬盘等，整机功耗大概在500-550W之间。850W留了约300W的余量，振华又是台系一线品牌，波纹和瞬态响应都不错，正常情况下完全能撑住。</p>
<p dir="auto">不过有几个地方要注意：</p>
<ol>
<li>如果你用的是振华的Leadex III或更高端系列（金牌/白金），850W完全没问题。如果是较老或入门级的振华，建议确认一下是单路+12V设计（单路更稳）。</li>
<li>7900XTX有瞬时功耗尖峰，好电源能扛住，但如果你同时给CPU超频或者插了多块PCIe设备，余量就紧了。</li>
<li>长远来看，电源用久了电容会老化，3-5年后余量变小。如果你想为未来升级留空间（比如换下一代旗舰卡），1000W更省心。</li>
</ol>
<p dir="auto">450RMB买振华850W金牌全模组的话，价格正常，不算贵也不算特别便宜。如果你现在预算允许，可以考虑直接上1000W（振华Leadex III Gold 1000W大概550-600RMB），一步到位更省事。</p>
<p dir="auto">总之：850W能用且稳定，1000W更安心。如果现在就买、近期不换大功率配置，850W足够了。想一步到位多花100多上1000W也行。</p>
