The Ocypus Iota P1000 is a new entrant into the high-power supply unit market. Offered as a fully modular 1000 W unit, the PSU carries both 80 Plus Gold certification and full Intel ATX 3.1 compliance.
The unit is engineered to handle modern high-end components, featuring native PCIe 5.1 support. This is delivered through an updated 12V-2×6 connector, which is rated to provide up to 600 W exclusively to advanced graphics cards.
Ocypus, based in Beijing, is a relatively new name in the DIY enthusiast space. The company has demonstrated rapid expansion across product categories including liquid coolers, chassis, and power supplies.
Internally, the Iota P1000 is built around a full-bridge LLC resonant converter and Active PFC circuitry. Further enhancing its build quality is the use of a 100% Japanese capacitor loadout.
For cooling, the PSU utilizes a 120 mm fluid dynamic bearing fan. This fan features a zero-RPM ECO mode, allowing it to remain stopped up to 50% of the unit’s capacity. These components point toward a foundation designed for quiet operation and high capability.
From a power perspective, the single +12 V rail is rated for 83.3 A, supporting the full 1000 W output. The auxiliary +5 V and +3.3 V rails each carry a 20 A rating, providing a combined maximum of 100 W.
The unit incorporates the standard safety suite, including protections for OPP, OVP, SCP, OTP, OCP, UVP, and a surge protective device.
Reviewing its performance, the unit delivered impressively quiet operation for a 1000 W model. Strong ripple control marks the PSU as a genuine strength, distinguishing it in the market. This combination of careful engineering and quiet acoustics makes it a compelling option.
However, the unit is not without minor flaws. Cable losses were identified during testing, a type of flaw that impacts voltage regulation when measured at the end of the cable run. Additionally, the +5 V and +3.3 V rails are noted to be less tightly optimized compared to the primary +12 V rail.
Despite these two specific criticisms, the overall assessment positions the Iota P1000 as a strong debut for the brand. It provides modern ATX 3.1 compliance, a native 12V-2×6 connection, and a competitive five-year warranty for its segment.
The core appeal lies in the trade-off: the PSU offers high-end internals and quiet operation, pairing these benefits with a budget-friendly price. Buyers seeking perfect minor-rail regulation or maximum efficiency might find small gaps, but the unit should not compromise a general enthusiast build.
