PSU Calculator by TechSearchers

What it does

Discover the right PSU wattage for your PC build with Tech Searchers. Add your components & get accurate, safe, & reliable recommendations.

Your PC just crashed mid-game. You’ve updated the drivers, reseated the GPU, and stress-tested the CPU — everything checks out. The real culprit is almost always the power supply, and it’s the last thing most builders think to check. An undersized PSU doesn’t always fail loudly. It trips its protection circuit during a millisecond power spike — the kind that happens every time your GPU starts rendering a new frame — and your system dies instantly. No warning. No error code. Just a black screen. This PSU calculator is built to catch that before it happens. Enter your CPU, GPU, RAM, storage, and cooling setup below. We apply real transient spike multipliers from Cybenetics…from techsearchers.com

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
