This article covers スーパーフラワー Leadex VII XG ホワイト 80 PLUS ゴールド.

Overview

The Super Flower Leadex VII XG SF-1300F14XG-W is a 1300W ATX 3.0 power supply with 80PLUS Gold certification. It features a native 12VHPWR connector compliant with PCIe 5.0, allowing direct power delivery to the latest high-end graphics cards without adapters. The white chassis fits perfectly into white-themed builds, and fully modular cabling makes cable management a breeze. Backed by a 10-year warranty, this PSU promises long-term reliability for demanding systems.

Compatibility Guide

This unit uses the standard ATX form factor and fits in most ATX, MicroATX, and E-ATX cases that can accommodate a 140mm deep PSU. With 1300W on tap, it can easily power a flagship CPU like the Core i9-14900K combined with an RTX 4090. The built-in 12VHPWR connector eliminates the need for dongles, streamlining the build. However, some compact cases may have limited PSU clearance, so double-check dimensions before purchase.

Product Info

Launched in 2024, the Leadex VII XG is Super Flower’s top-tier model within its gold-rated lineup. It occupies the high-end market segment, offering 1300W capacity, Gold efficiency (up to ~90% under typical load), and ATX 3.0 transient load resilience. The power supply comes with a full set of modular cables including multiple PCIe 6+2 and 12VHPWR, plus standard ATX and EPS connectors. Warranty coverage is 10 years, underscoring its durability.

Best Use Cases

This PSU is ideal for enthusiast gaming rigs built around the RTX 4090 or future PCIe 5.0 GPUs, where the native 12VHPWR and ample wattage provide headroom for overclocking and transient spikes. It also suits high-performance workstations used for 3D rendering, video editing, or AI training, where sustained loads demand consistent power delivery. For builders designing a white aesthetic PC, the white color scheme and clean modular cables help achieve a unified look. ## Alternatives
In the same price tier, the Seasonic Vertex GX-1200 (1200W, Gold, ATX 3.0) and Corsair RM1200x Shift (1200W, Gold, ATX 3.0) are direct competitors. Seasonic offers slightly lower wattage but equally stable output. The Corsair Shift features side-mounted connectors for easier cable routing in certain cases. The Leadex VII XG sets itself apart with a 1300W capacity, white finish, and a native 12VHPWR connector, making it a strong choice for white-themed high-end builds.

Things to Consider

At 1300W, this unit is overkill for mid-range systems running, say, an RTX 5070 or RX 9070; a 850W or 1000W unit would be more cost-effective. Competitors like the Seasonic Vertex GX-1200 or Corsair RM1200x Shift offer similar performance and pricing, but the Leadex VII XG stands out for its white finish and native 12VHPWR. Availability via official channels can be spotty in some regions, so and select specialty retailers are the main purchase options. If your build doesn't need 1300W, consider the 1000W version to save cost.
