Inter-Tech Argus HA-850BA4 — 850W fully modular ATX 3.1, 80 PLUS Gold
850W ATX 3.180 PLUS GoldFully modular8× SATA
The Inter-Tech Argus HA-850BA4 is an 850W fully modular ATX 3.1 power supply with 80 PLUS Gold efficiency, suited to gaming PCs and workstations that combine a modern PCIe 5.x graphics card with plenty of drives.
Inter-Tech publishes 86.1/90.3/92.2/90.0% efficiency at 230V for 10/20/50/100% load. The +12V output is rated at 70.8A, there is a 600W 12VHPWR cable for current GPUs, eight SATA connectors, and the fan is temperature-controlled between 0 and 1200rpm — it stays off below 65°C internal temperature. Protections include OPP, OCP, OVP, SCP, no-load protection and over-temperature.
Before you order: Inter-Tech names the GPU cable "12VHPWR". It fits graphics cards with a 12VHPWR or 12V-2x6 socket; seat the plug fully until it clicks.
What's in the Box
- Inter-Tech Argus HA-850BA4 power supply
- Modular connection cables (all black)
- AC power cord
- Mounting screws and cable ties
- Manual
What It Means in Practice
- Fully modular: connect only the cables you need, which keeps airflow clean and makes later upgrades easier.
- Eight SATA connectors cover multi-drive builds, NAS-style home servers and workstations.
- Wide 100–240V input with active PFC (>0.97).
- At light load the fan can stop completely, so idle and desktop work stay silent.
What Will Not Work
- The 165mm depth is longer than a 140mm ATX unit — check PSU clearance in compact cases.
- It is not an SFX unit and will not fit small-form-factor cases.
- Inter-Tech does not publish the fan size or bearing type.
- Do not reuse modular cables from other PSU brands — pinouts differ and can damage components.
