SFX-L 1000W platinum power supply
This fully modular SFX-L unit delivers 1000 W of continuous power for small form factor computers that need high output in a compact 130 mm chassis. It suits builders assembling dense workstations or gaming systems where space is limited but demand is high. The 80 PLUS Platinum certification confirms strong efficiency across typical loads.
Single +12V rail with 83.3A capacity
The class-leading single +12V rail provides 83.3 A, giving ample headroom for modern multi-core CPUs and high-end graphics cards running simultaneously. At full 1000 W load the unit operates within strict 3 % voltage regulation and low ripple. Continuous 24/7 rating at 50 °C ambient ensures stability during sustained heavy workloads.
SFX-L form factor and modular cabling
The 130 mm SFX-L length fits many compact cases but exceeds standard SFX dimensions, so builders must verify chassis clearance before purchase. Fully modular flat cables reduce clutter yet remain short, limiting routing options in larger enclosures. The 120 mm dual ball bearing fan runs semi-fanless at low load but spins up under sustained demand.

Questions about this item
Will the 130 mm length SFX-L unit fit in my existing small form factor case?
The SFX-L form factor measures 130 mm in length and is designed for small form factor computers, so it fits cases built to the SFX-L standard.
How can I verify the 120 mm fan is running correctly after installation?
The 120 mm dual ball bearing fan features semi-fanless operation, meaning it spins only when internal temperature requires active cooling.
Which cables come in the box and what must I source separately?
The unit is fully modular with 100% modular short cables using flexible flat arrays; only the cables required for your build need be connected.
