Frequently Asked Questions
Do I need special cables for my new GPU?
Most GPUs need PCIe power cables that match your PSU brand and type. Always confirm compatibility, as mixing modular cables between PSU brands can be dangerous.
Why would I need a DisplayPort-to-HDMI adapter?
Modern GPUs favor DisplayPort, but many monitors, TVs, and projectors use HDMI. A uni-directional DP-to-HDMI adapter bridges that gap so you can connect any display.
Are third-party PSU cables safe?
Yes, if they are made for your exact PSU model and type. Never reuse cables across different power supply brands, since pinouts differ and can damage components.
What resolution can these adapters handle?
It varies by model, typically up to 4K@30Hz or 1080P at higher refresh rates. Check the spec if you need 4K@60Hz or high-refresh gaming output.
