NVIDIA RTX 5090 Overclock Reaches 700 W Without a Shunt Mod

Posted on Edited on
New mVolt+ tools let enthusiasts bypass stock limits, pushing an RTX 5090 to 700 W and an RTX 5080 to 680 W in reported tests.

Quick Report

An update to the mVolt+ utility appears to let users bypass the stock power limits of selected NVIDIA RTX 50-series graphics cards without a shunt mod or custom vBIOS. One reported test pushed an RTX 5090 to 700 W and reached 3,127 MHz, while another drove an ASUS ROG Astral RTX 5080 OC to 680 W.

The RTX 5090 result used 125 W more than its 575 W reference TDP and recorded 16,523 points in 3DMark Steel Nomad. The RTX 5080 test exceeded its 400 W stock rating and reached 3,390 MHz in FurMark, but the extreme power levels create serious risks for the GPU, power supply, and 12V-2x6 connection.
