About SUNFUN TECH

We're a U.S.-based computer hardware retailer on a mission to make genuine PC components and peripherals accessible, affordable, and easy to buy.

Built by PC builders, for PC builders.

SUNFUN TECH was founded on a simple frustration: buying computer parts in the U.S. had become unnecessarily complicated. Prices were opaque, stock was unreliable, and customer service often felt like an afterthought. We knew there had to be a better way.

So we built one. Starting from a small warehouse in Chino, California, we set out to create a retailer that puts the customer first — one that stocks the parts people actually want, ships them quickly, and stands behind every product we sell.

Today, SUNFUN TECH serves PC builders, gamers, students, and small businesses across the United States. Whether you're putting together your first budget gaming rig or upgrading a high-end workstation, our goal is the same: genuine parts, fair prices, and support you can count on.

We're not the biggest hardware retailer in America — and that's exactly the point. Staying focused lets us move faster, know our products better, and give every customer the attention they deserve.
