ASUS's ROG Equalizer 12V-2×6 power cable, designed to balance load across pins, has been found to underperform. According to overclocker Der8auer, the cable fails to equalize current distribution, with differences reaching up to 4A between pins on an RTX 5090.
The issue stems from an internal bridge that adds 1-2 mΩ of resistance. After removing the bridge, the maximum pin current dropped to 8.9A and the minimum to 7.5A, significantly improving balance.
Internal bridge adds resistance
The ROG Equalizer is available in China since early April 2025. Pricing is 1399 CNY (about $205) for the 850W model, 1599 CNY (about $234) for the 1000W model, and 1899 CNY (about $278) for the 1200W model.
Specifications
- Current imbalance between pins: up to 4A difference
- Additional resistance from bridge: 1-2 mΩ
- Current after bridge removal (max pin): 8.9A
- Current after bridge removal (min pin): 7.5A
The cable's design flaw contradicts its advertised load-balancing feature. Der8auer's testing indicates that in some scenarios, the ROG Equalizer performs worse than standard cables. ASUS has not yet commented on the findings.
