Is 1000W enough for a GPU mining rig in Australia?

A 1000W PSU is suitable for entry-level mining rigs running 2 to 3 mid-range GPUs such as the RX 6600 XT or RX 5700 XT alongside a CPU, motherboard, and fans. For larger rigs with 4 or more GPUs or high-power cards like the RX 6800 XT or RTX 3080 you will need the 2000W unit instead. As a rule of thumb total continuous GPU power draw plus system overhead should not exceed 80 percent of PSU rated capacity to ensure stable operation and component longevity. Calculate your total wattage including power-limited GPU settings before purchasing.

What does full modular mean and why does it matter for mining rigs?

Full modular means every cable detaches from the PSU body so you only connect the cables your build requires. In mining rigs this is critical for airflow management and clean cable routing inside open-frame chassis. Unused cables do not clutter the build which improves ventilation and reduces heat buildup around the PSU and GPUs. It also simplifies maintenance and GPU swaps since you can disconnect individual PCIe power cables without disturbing the rest of the wiring. Non-modular PSUs with permanently attached cables create clutter that restricts airflow in multi-GPU setups.

Will this PSU work on 240V Australian power outlets?

Yes. This PSU supports 110V to 220V input range which covers Australian 240V mains electricity. Ensure you use the correct IEC C13 or C14 power cord rated for Australian 240V 10A outlets. Do not exceed the PSU continuous wattage rating on any single circuit and have a licensed electrician install a dedicated circuit if you are running multiple mining rigs in the same space. Australian electrical safety regulations require all fixed wiring work to be performed by a licensed professional.

How many GPUs can I power with this 1000W PSU for mining?

The number of GPUs depends on each card power draw after power limiting. At 80 percent safe load you have 800 watts available for the entire system. A typical mining motherboard CPU RAM and fans consume 80-120 watts leaving 680-720 watts for GPUs. Two RX 6600 XT cards at 100 watts each or two RX 5700 XT at 160 watts each fit comfortably. Three power-limited mid-range cards may also work but calculate carefully and monitor rail voltages under load. For 4 or more GPUs consider the 2000W mining PSU instead.

Does MinerHub provide warranty on the 1000W mining PSU in Australia?

Yes. The 1000W Full Modular ATX Mining PSU is sold with manufacturer warranty and full Australian Consumer Law protections through MinerHub. We ship Australia-wide from Perth WA with same-day dispatch on orders before 2:00 PM AWST. If your PSU develops a fault contact hello@minerhub.com.au with your order number and fault description for warranty assessment and replacement.

Product Details

The 1000W Full Modular ATX PSU is a fully detachable-cable power supply designed for high-performance desktop builds, single-GPU gaming systems, and compact GPU mining setups running up to 3–4 mid-range cards. The full-modular design lets you connect only the cables you need, improving airflow through the chassis and keeping cable clutter to a minimum — particularly useful in open-frame mining rigs where heat extraction is critical during the Australian summer.

The PSU outputs a continuous 1000W on the +12V rail, with standard ATX connectors covering motherboard (24-pin), CPU (8-pin EPS12V), graphics (multiple 6+2-pin PCIe), SATA, and peripheral Molex. Input range supports 100–240V AC with active PFC, making it directly compatible with Australian 240V single-phase supply at 50Hz. Built-in protections cover OVP (over-voltage), OCP (over-current), OPP (over-power), SCP (short-circuit), and OTP (over-temperature) — standard safety features for any modern ATX PSU.

For Australian GPU miners, sizing the PSU correctly matters more than headline wattage. A 1000W unit running at 60–70% load sits in its efficiency sweet spot and runs cool and quiet. That translates to around 600–700W of sustained GPU + system load — enough for two RTX 3080-class cards, three RX 6700 XT-class cards, or four lower-power mining cards like the RX 580 or BC-250. Beyond that, step up to the 2000W mining PSU or pair two units with a synchroniser board.

Suitable for desktop PC use, gaming, content creation, and small mining rigs. For larger 6+ GPU rigs or ASIC miners, this PSU is undersized — consider a purpose-built mining PSU instead. Installation in standard ATX, EATX, and most mATX chassis. A licensed electrician should be consulted for any dedicated mining circuit installation to comply with AS/NZS 3000:2018 wiring rules.
