I'm using an NZXT C1000 ATX 3.1 power supply, model PS-2303, and recently bought a Gigabyte Radeon 9070 XT OC. I misplaced one of the original PCIe cables, so I need a safe replacement in the United States. What cables or retailers are compatible with this exact PSU, and are there any reasonably priced options?

CableMod is one option, but make sure you select the exact NZXT C1000 ATX 3.1 model, PS-2303. Modular PSU cables are not universally interchangeable, even when the connectors look identical. NZXT’s own replacement cables or support team would be the safest first choice.
Check the label on the PSU and the cable listing for PS-2303 and ATX 3.1 compatibility. You can also compare the connector and pinout with the PSU manual or ask NZXT support before ordering.
For a cheaper option, look for a replacement listed specifically for NZXT modular power supplies from a reputable cable maker. Avoid generic or used modular cables unless the seller provides confirmed pinout compatibility. A mismatched cable can damage the PSU or graphics card, so saving a few dollars isn’t worth guessing.
Are there any budget alternatives that are still safe?
The best budget route is usually an official NZXT replacement or a properly matched third-party cable. Don’t rely only on the connector shape; verify the exact PSU model and pinout first.

How can I confirm that I’m choosing the right cable and not a cable for a different C1000 revision?
