GoKawiilGigabyte's 1000GM PG5 PSU tested: Platinum efficiency, T-Guard connector protection
Tom's Hardware reviewed Gigabyte's Gaming 1000GM PG5 1000W power supply, built by OEM HEC, finding it achieves Platinum-level efficiency despite carrying only a Gold badge. The unit uses all-Japanese capacitors, a 135mm fluid dynamic bearing fan, and includes T-Guard, a thermal monitoring feature for its native 12V-2x6 connector that can cut power if overheating is detected. It ships with a ten-year warranty and costs $170.
GoKawiil's interpretation of the reporting above, not reported fact.
The review suggests T-Guard could offer reassurance to owners of high-end GPUs, whose 12V-2x6 connectors have been a known point of failure risk in high-power systems. Achieving Platinum efficiency while only badged Gold indicates Gigabyte may be under-marketing the unit's actual performance, which could work in buyers' favor at this price point. The reviewer notes the fan gets loud under heavy load, a trade-off buyers should weigh against the thermal safety features.
- Gigabyte's 1000GM PG5 tested at Platinum efficiency despite a Gold-rated box label.
- T-Guard thermal monitoring on the 12V-2x6 connector adds a safety layer for high-end GPU setups.
- Priced at $170 with a ten-year warranty, though fan noise increases under heavy thermal load.
