Howard G. Smith MD, AM on Instagram: "Manik and Apex-branded ATX Computer Power Supplies Lack Shocking Warnings These computer power supplies lack a required warning label identifying electrical shock and electrocution hazards should the product be opened or disassembled. Affected: 450W, 750W, 1000W, and 1200W models. About 17,730 of these power supplies were sold in the US and an additional 500 were sold in Canada online at ApexGamingPCs.com from December 2021 through February 2026. Stop using these power supplies. Contact Apex Gaming PCs at 1-833-946-1418 or [email protected] for a free repair in the form of a safety warning label that will be mailed to you. If you are uncomfortable applying the label, request a free replacement unit. If you do, you must then return the original unit using the provided shipping label.

⚡ How to Choose the Right Circuit Breaker (Not just amps!)
A correct breaker selection depends on:
✅ Rated current (A)
✅ Poles (1P/2P/3P/4P)
✅ Voltage (AC/DC)
✅ Breaking capacity (kA)
✅ Trip curve (B/C/D)
✅ Accessories (Aux, Shunt Trip, UVR)
We published a step-by-step guide with a quick checklist you can use for panels and machines:

⚡ MCB vs MCCB vs RCCB vs RCBO — what should you choose?
Most people select breakers only by amps, but the real differences are about what fault they protect against:
✅ Overload
✅ Short circuit
✅ Earth leakage (shock/fire protection)
We published a practical guide with use-cases + a quick selection checklist.
