ESD Guards ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10 kV of air discharge and +/- 6 kV of contact discharge — greatly surpassing the respective industry standards of +/- 6 kV and +/- 4 kV. Surface-mounted TVS diodes in a dual in-line package help protect your PC from voltage spikes. SafeSlot & SafeDIMM SafeSlot is a reinforced metal sheath added to a PCIe slot to keep a card firmly installed. Because PCIe 5.0 is two times faster than PCIe 4.0, ASUS enhanced SMT manufacturing processes for the faster SafeSlot―all to ensure users get the highest-possible data speeds. In addition, the ASUS SafeDIMM sheath is added to support and protect memory modules on select ASUS motherboards, empowering you to insert modules with speed, accuracy and confidence. PCIe Q-Release A physical button unlocks the first PCIe slot’s security latch with one tap, greatly simplifying the process of detaching a PCIe card from the motherboard when it’s time to upgrade to a new GPU or other compatible device.
