Asus ROG Strix 1000W Platinum ATX v3.1 PSU Review

The ASUS power supply ships in a box with a photo on the front, along with some key selling points listed bottom right. These include the Platinum efficiency badge, the Cybenetic A+ noise certification, the 10 year warranty logo and the ATX 3.1 compatibility. I was rather confused to see the Cybenetics efficiency badge doesn't seem to be listed, just the noise one.

The rear of the box is loaded with information, including the GaN MOSFETs, Intelligent Voltage Stabiliser – GPU Sense and other things such as ‘DIY Friendly' cables, and the ROG Heatsinks.

The power supply ships well sandwiched between pieces of foam. Packaging is good. Inside the box, we see some ‘stickers' that ASUS include to let the end user customise the looks of the power supply.

The ASUS bundle is comprehensive. You get a variety of cable ties, both plastic and felt, and our sample included several power cables for Europe and the United Kingdom.

Package contents:
Power Cord x 1
Motherboard Power Cable x 1 (610mm)
CPU Cable x 2 (1000mm)
PCI-E Gen 5.1 (16-pin-to-16-pin) Cable x 1 (750mm)
PCI-E (8-pin-to-6+2pin) Cable x 4 (750mm)
SATA 1-to-3 Cable x 2 (400+120+120mm)
Peripheral 1-to-3 Cable x 1 (400+150+150mm)
ROG Strix DIY sticker x 1
User Manual x 1

The quality of these individually sleeved cables seems really good, they are soft and flexible and are easily bent during use. Asus say the cables operate at temperatures '50c lower than the safety limit when bent'. They meet UL1581 flame test and UL758 certifications.

Asus say that these cables have upgraded copper pins which improves thermal conductivity for cooler operation and improved power delivery efficiency.  Their claimed reductions in temperatures are 29% which translates to up to 12.28c.

  • ATX connector 20+4 pin (610mm) x 1 Cable and 1 Connector.
  • 4+4 Pin EPS12V (1000mm) x 2 Cables and 2 Connectors.
  • 12+4 Pin PCIe (745mm) (600w) x 1 Cable and 1 Connector.
  • 6+2 Pin PCIe (750mm) x4 Cables and 4 Connectors.
  • SATA (400mm+115mm+115mm) x 1 Cable and 3 Connectors.
  • SATA (400mm+120mm+120mm) x 1 Cable and 3 Connectors.
  • 4 Pin Molex (400mm+150mm+150mm) x 1 Cable and 3 Connectors.

The cable configuration for this power supply is pretty robust and the cables are long enough to suit a variety of large case designs on the market today. None of the cables have in cable capacitors inside and they all measure around 18AWG Gauge with the 600W cable measuring 16-24AWG. Asus did a pretty good job here of supplying quality, flexible cables which are noticeably better than most I have tested in recent years.
