Where Can I Find Affordable Cables for My Seasonic GM-500 PSU?

Asked by Wanderlust42
I recently purchased a Seasonic GM-500 semi-modular power supply, and it requires both PCIE and SATA cables. Unfortunately, I didn't do my research beforehand, and now I'm struggling to find where to buy compatible cables at a reasonable price. So far, the prices I've seen for replacement cables are higher than what I paid for the PSU itself! Any suggestions would be greatly appreciated.

Your PSU should've come with two PCIe cables and two SATA cables included right out of the box. Did you buy it second-hand? Sometimes used units can be missing those extras. If it really didn't come with them, you might want to reach out to Seasonic directly for help; they might send you the cables for free if you can provide proof of purchase.

Unfortunately, I found that no modular cables are included with mineโ€”just the integrated options. So, I'm in the same boat and yes, it's a pain trying to hunt down separate cables.

Check directly with Seasonic's customer service. They might help you out especially if you can provide a receipt. Itโ€™s worth a shot! Also, be aware that some brands like Corsair have markings on their cables to indicate compatibility; if you find any of those, they might fit.

I totally get your frustration! Semi-modular PSUs like yours typically come with all necessary cables. Prices for new PSUs are pretty competitive right nowโ€”you can find solid models for about $50-$60, and they even go down to $40 on sale. If you're stuck, it might be worth considering just upgrading to a complete unit.

Wanderlust42: Yeah, I bought it used and didnโ€™t expect the hassle of sourcing the cables. Kinda regretting it now!
