12 Capacitors blown in one RX-700AC 80Plus power supply. Not always an easy job but all working great now.

Now we've seen capacitors blowing their tops but this is abnormal. Where's the fanfare, the loud pop, the smoke and the terrible smell that comes with it? 😂

WhatsApp accounts taken over in South Africa

WhatsApp Scam Warning for South Africans

Cybercriminals are increasingly hijacking WhatsApp accounts belonging to South Africans and using them to impersonate victims in order to scam their friends, family, and colleagues.

Victims are often locked out of their own accounts while scammers send messages requesting money or sensitive information from trusted contacts.

Experts say these attacks are carried out using phishing links, social engineering, leaked login credentials, and SIM swap fraud.

⚠️ Protect yourself:
* Never share your WhatsApp verification code with anyone.
* Enable two-step verification in WhatsApp.
* Be cautious of unexpected messages or links.
* If a friend asks for money via WhatsApp, verify the request by calling them directly.

Stay vigilant and share this warning to help protect others from becoming the next victim.
