Silverstone SX1000-LPT (1000W/80+ Platinum/ATX 3.0/High-End/Multi-Gpu Tier) Review

Silverstone SX1000-LPT 1000W 80 Plus Platinum fully modular power supply, ATX 3.0 certified, SFX-L form factor, native 12V-2x6/12VHPWR connector, 3-year warranty, Enhance Electronics platform.

The Silverstone SX1000-LPT is one of the highest-density SFX-L units on the market, packing 1000W of Platinum-rated power into a chassis barely larger than a standard SFX unit. Rated 1000W at 80 PLUS Platinum (Cybenetics Platinum efficiency / A- noise), it's built on a Enhance Electronics platform with a 80mm dual ball bearing fan. Fully Modular cabling and a 130mm chassis depth make it a realistic fit for an extreme small-form-factor build pushing a flagship GPU into a Mini-ITX case, and it's backed by a 3-year warranty.

Efficiency, Noise, and Build Quality

The SX1000-LPT carries an 80 PLUS Platinum certification and a Cybenetics Platinum efficiency / A- noise rating, translating to consistently high real-world efficiency at typical 50% load and low fan noise thanks to its 80mm dual ball bearing, high static pressure. It uses a Enhance Electronics platform, a common approach at this price point that keeps the unit affordable without meaningfully hurting day-to-day reliability.

Connectors and Cabling

Connector layout is 1x 24-pin ATX, 1x EPS 4+4, 1x 12V-2x6 (600W), 4x PCIe 6+2-pin, 6x SATA, 2x Molex. With 1 native 12V-2x6 connector(s) rated to deliver up to 600W to a single GPU, there's no need for a 4x8-pin-to-12VHPWR adapter on current-generation flagship cards. Cabling is fully modular, using standard flat or ribbon cables, with a single +12V rail design that simplifies load balancing across connectors.

Comparison to Alternatives

Against the Seasonic Prime 1000 Platinum (Seasonic's 1000W Platinum flagship), the Silverstone SX1000-LPT matches its wattage class but differs on connector generation and OEM platform, making the choice mostly about brand ecosystem, warranty length (3 years here), and whether native 12V-2x6 connectors matter for your GPU. Compared with the Thermaltake Toughpower GF3 850W (Thermaltake's native-12VHPWR 850W Gold unit), the SX1000-LPT sits in the high-end/multi-GPU bracket at 1000W, so the decision usually comes down to matching wattage headroom to your actual GPU/CPU combo rather than one being categorically better.

Expert rating8.7 / 10

A best-in-class 1000W Platinum-rated SFX-L unit for an extreme small-form-factor build pushing a flagship GPU into a Mini-ITX case, held back only by its premium price.

Best for

  • Builders targeting an extreme small-form-factor build pushing a flagship GPU into a Mini-ITX case
  • Anyone who wants fully modular cabling with native 12V-2x6 support
  • Systems where a 3-year warranty and Platinum-tier efficiency matter

Not for

  • Builds needing more than 1000W of continuous headroom
  • Buyers who need a full-size ATX chassis
  • Cost-sensitive builds better served by a lower-tier 80+ Bronze unit
