The DeepCool PX1000G is a 1000 W fully modular ATX 3.0 power supply with an additional hybrid fan mode. Priced at $149.99 USD, it is advertised to be 80PLUS Gold rated and Cybenetics Platinum.
As of June 2024, DeepCool is notably placed on the ‘Specifically Designated Nationals and Blocked Persons List’ (SDN List) due to sales worth over $1 million to two Russian companies. DeepCool has since issued a statement stating that they were only selling computer parts for civilian use. As a result of being placed on the SDN List, 80PLUS does not have an official database listing for the Gold certification despite DeepCool using the Gold badge, and marketing as such. Its Cybenetics ratings listing is under a pseudonym, “Gamer Storm PX1000G”, and from what we can tell, this is likely the same PX1000G power supply.
Despite this, the power supply itself delivered low voltage ripple and consistent protections, surviving the OCP tests. As of publication date DeepCool power supplies are not available from US online retailers.
WHAT YOU NEED TO KNOW
THE GOOD
- Voltage Ripple
The power supply delivers low voltage ripple/noise; it stands out for its stability.
THE BAD
- Availability
As of publication date DeepCool power supplies are not available from Canadian or US online retailers.
THE REST
- Overall
The power supply delivered low voltage ripple and reasonably long brownout duration. It also came in sturdy packaging.
The DeepCool PX1000G is an ATX form factor power supply. In the Box, it includes sufficient accessories, providing plenty of cables, user documentation, mounting bolts, PSU tester, and velcro cable ties. The included cables are flat and flexible. The included 12VHPWR cable is rated for up to 600 W.
This unit is equipped with a 135 mm Fluid Dynamic Bearing fan. The power ratings and specifications align with expectations for this price range. On the DeepCool specifications webpage it specifies that the Operating Temperature range is 0°C to 40°C, though we cannot verify this through testing.

The PX1000G offers an additional hybrid fan mode. In its zero RPM mode it is advertised to dynamically adjust once the system load hits a certain threshold. This mode can be controlled using a physical switch on the rear of the power supply.
This unit comes with all of the standard protections and is backed by a 10 year warranty.
In terms of overall performance, the PX1000G demonstrated average capabilities. During testing the 12V rail showed a voltage drop of 0.234 V across the full 1000 W output, which remains within ATX specifications but is worse than other power supplies we’ve tested. This power supply meets ATX ripple specifications, with a peak-to-peak ripple of 22 mV on the 12V rail under full load. The 5V and 3.3V rails also performed better than expected, exhibiting signal ripples of 15 mV and 25 mV, respectively.
In terms of excursion testing, the power supply was able to sustain all of the excursion tests, and passed most points, except for the 12V rail at the faster/shorter duration excursions. The voltage dipped below the minimum specification (11.2 V) and exceeded the maximum voltage specification (12.6 V) in some cases.

The PX1000G is advertised to be rated at 80PLUS Gold, and despite the aforementioned sanctions disputations, we have tested the PX1000G as such. During testing it achieved 90% efficiency at 50% of its maximum rated load. The efficiency is a bit lower than the average power supply that is advertised as 80PLUS Gold.
This power supply provided a bit higher than average resilience to brownouts and power dropouts, enduring 17 ms at full load for both 115V and 230V inputs. The OPP engaged at a maximum of 125% of rated load, with the 12V rail alone capable of 104 A, or 125% of its rating. This is equivalent to similarly rated power supplies offering good protection against component faults.
