Zalman GigaMax 600W ATX PSU

This Zalman GigaMax unit delivers 600 W of continuous power through a non-modular ATX design. It targets builders assembling mid-range desktops or entry-level workstations who need reliable delivery without cable clutter from unused modular ports. The single 120 mm sleeve-bearing fan and all-black sleeved cables simplify installation in standard cases.

Sustained-load behaviour with Active PFC

Active PFC maintains a 99 % power factor across the 100-240 V input range, keeping output rails stable during extended gaming or compute sessions. 80 PLUS Bronze certification confirms 85 % typical efficiency at 20 %, 50 % and 100 % loads, so waste heat stays predictable even when the system runs for hours. Dual 6+2-pin PCIe connectors support multi-GPU configurations without rail sag.

Thermals noise and power draw in normal use

The 120 mm sleeve-bearing fan operates quietly at typical loads while the 105 °C rated capacitors handle internal temperatures up to 40 °C ambient. Full protection circuitry — OCP, OVP, OPP, OTP, UVP, SCP — shuts the unit down safely if thresholds are exceeded. MTBF exceeds 100,000 hours, reflecting the robust component selection and certified safety approvals.

Questions about this item

Will the 600 W capacity support a dual-GPU setup with two 6+2-pin connectors?

The unit provides two 6+2-pin PCIe connectors and is rated for 600 W, so it can power two graphics cards within that total budget.

Does the 140 mm depth fit a standard ATX case?

At 140 mm long, 150 mm wide and 86 mm high it matches the Intel ATX 12V 2.31 form factor used by most mid-tower cases.

How loud is the 120 mm sleeve-bearing fan under load?

The 120 mm sleeve-bearing fan is designed for low-noise operation, and the Bronze efficiency target of up to 85 % helps keep heat and fan speed down.
