🌟 The Good: Why People Buy It

*Modular Cables:* This is its biggest selling point. In cases under 5L, excess cables are a nightmare. Being able to plug in only what you need is a massive advantage over standard Flex PSUs like the FSP Group units.
*Power Density:* Finding 500W or 600W in a 1U form factor at this price point is difficult. It can technically power mid-range GPUs (like an RTX 4060 Ti or 4070) alongside a modern i5 or Ryzen 5.
*Stability:* Most users report stable 12V rails and successful "high-temperature aging tests" at 50°C.

⚠️ The "Catch": What to Watch For

*The "Scream":* Small 40mm fans must spin very fast to move enough air. At high loads, the stock fan is notoriously loud—often described as a "jet engine." Many enthusiasts perform a "Noctua Fan Swap" (replacing the stock fan with an A4x20 FLX), though this voids the warranty and can be risky if the PSU overheats under maximum load.
*Certification Clarity:* While marketed as "80 PLUS Gold," some users have noted the lack of official certification labels on early boxes or variations in the actual efficiency depending on the specific batch or "Diamond" vs "Standard" versions.
*Cables:* While modular, the cables are often stiff. Some versions include "pigtail" connectors (e.g., two 6+2 pins on one cable) which can be bulky in tiny cases.

💡 Recommendation

The METALFISH Flex Gold is a solid *mid-tier* option.

*Get it if:* You are on a budget, building in a case like the K39, and value modularity above all else.
*Skip it if:* You want absolute silence out of the box. In that case, the *Enhance ENP-7660B (600W Platinum)* is the gold standard for Flex PSUs, though it is significantly more expensive and often non-modular.

*Would you like me to look up a compatibility check for a specific PC case or GPU you’re planning to use with this PSU?*
