| 5V/5A USB-C power supply | The official one is recommended |
| Active cooler | The Pi 5 and SSD get warm |
| Ethernet cable | Recommended during install |
| RTC battery (optional) | Keeps system time offline (e.g. official SC1163) |

> **RTC battery note:** Without internet access, the Pi 5 cannot sync time via NTP. When power is lost, the internal RTC clock resets unless a backup battery is connected to the J5 (BAT) connector. If you use the official rechargeable Panasonic ML-2020 battery (SC1163), enable trickle-charging by adding `dtparam=rtc_bbat_vchg=3000000` to `/boot/firmware/config.txt`. *(Do not enable charging if using standard non-rechargeable CR2032 cells).*

> **RTC pili notu:** Afet durumunda internet bağlantısı olmadığı için Pi 5 zamanı NTP üzerinden eşitleyemez. Elektrik kesildiğinde sistem saatinin sıfırlanmaması için Pi 5'in J5 (BAT) yuvasına bir yedek pil takılması önerilir. Resmi şarj edilebilir Panasonic ML-2020 pil (SC1163) kullanıyorsanız, `/boot/firmware/config.txt` dosyasına `dtparam=rtc_bbat_vchg=3000000` ekleyerek şarj özelliğini açabilirsiniz. *(Standart şarj edilmeyen CR2032 pillerde bu ayarı kesinlikle açmayın).*
