Fuente de alimentación AZZA PSAZ-650B (ATX3.1) 650 W, 20+4-pin ATX, no modular, 80 PLUS Bronze, negra

AZZA PSAZ-650B (ATX3.1) is a 650 W ATX power supply designed for desktop PCs. It provides stable 200–240 V AC input at 50/60 Hz, delivers up to 650 W total power, and uses a 20+4 pin ATX motherboard connector. The unit is non-modular, comes in black, and holds 80 PLUS Bronze efficiency certification along with international safety marks (FCC, CE, TUV, RoHS, RCM, CB).

Advantages

The PSU complies with ATX12V V3.1 and features an LLC half-bridge topology with DC-DC modules and high-efficiency electrolytic capacitors for improved voltage stability. Typical efficiency is 86% under common load, and a 120 mm smart sleeve-bearing fan provides active cooling. The supply includes full protection circuitry (OCP, OVP, OPP, SCP, OTP, UVP) and supports PCIe Gen 5.1 graphics cards via a high-quality 12V-2x6 16-pin cable capable of 450 W output.

Suitable for

• Mid-range and entry-level desktop gaming PCs
• Office and home workstation builds requiring ATX form factor
• Systems using a single PCIe Gen5.1 graphics card (within cable/rail limits)

How to use

Install the PSU into a compatible ATX case aligned with the case mounting points and secure it with screws. Connect the 20+4 pin ATX cable to the motherboard main power socket. Attach the required peripheral and PCIe power cables to components, ensuring the 12V-2x6 16-pin cable is used for supported PCIe Gen5.1 graphics cards within its 450 W limit. Verify AC input matches 200–240 V and switch on the power after all internal connections are secured.

Recommendations

Ensure the system’s total power draw does not exceed the PSU’s 650 W rating and observe the 12V-2x6 cable 450 W limit when powering high-consumption graphics cards. Maintain adequate case airflow and periodic dust cleaning to preserve fan performance and component longevity.
