FG423-30 vs FG423-48 — Compare
AMX PS3.0 Power Supply - 12VDC 3.0A 1.3mm Barrel Connector vs AMX PSR5.4 Power Supply - 12VDC 5.4A 1x 3.5mm Phoenix Connector, Retention Screws
The PS3.0 is a compact, budget-friendly option with a standard barrel connector for simpler installations, while the PSR5.4 delivers nearly twice the current (5.4A vs. 3.0A) with a more secure Phoenix connector for multi-device or higher-draw systems. Choose the PS3.0 for single light-load devices; pick the PSR5.4 if you need to power multiple networked devices or anticipate future expansion.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
What's the main difference in power capacity?
The PS3.0 delivers 3.0A, while the PSR5.4 delivers 5.4A—nearly twice as much. For systems with multiple networked devices or higher-draw equipment, the PSR5.4 provides more headroom and reduces risk of brownouts.
Which connector is more reliable for permanent installations?
The PSR5.4's Phoenix connector with retention screws is more secure and less prone to accidental disconnection than the PS3.0's barrel plug, making it better for fixed AV systems where cables stay connected long-term.
Does the PSR5.4's lower ripple matter for my setup?
Yes, if you're powering networked control processors or sensitive audio/video devices. The PSR5.4's 200 mV ripple specification ensures cleaner DC power and can reduce noise or intermittent connectivity issues in professional installations.
Will the PS3.0 work with all my AV equipment?
The 1.3mm barrel connector is widely standardized in professional AV, but always verify your device's connector size and current requirement before purchasing. The PSR5.4's Phoenix connector is less universal, so confirm compatibility with your specific equipment.
