SFX12V 4.0 850 W power supply
This SFX12V 4.0 unit delivers 850 W in a compact form factor. It targets small-form-factor builders who need high output for modern GPUs. The fully modular design uses flexible flat cables for tight routing. All Japanese electrolytic capacitors support long-term reliability.
SFX12V 4.0 interface limits
The SFX12V 4.0 standard defines the physical envelope and the 12VHPWR connector pinout. Input voltage must sit between 180 and 264 V at 47 to 63 Hz. Overall efficiency is rated between 89 and 91 percent under Cybenetics Platinum. The 92 mm FDB fan can stop at low load for 0 dBA minimum noise.
12VHPWR connector decides fit
A single 12VHPWR 12+4 pin connector is the only Gen5 PCIe 5.0 power interface on this unit. If the graphics card requires that connector, this supply matches; if it uses legacy 6+2 pin only, the extra adapter adds bulk. No other specification overrides this connector requirement.

คำถามเกี่ยวกับสินค้านี้
Will this SFX unit fit in a case that only accepts standard SFX dimensions?
The housing measures 125 x 63.5 x 100 mm, matching the SFX form factor, so it fits any chassis designed for that size.
Can I power a modern graphics card that requires the 12VHPWR connector without an adapter?
Yes, the supply includes a native 12+4 pin 12VHPWR cable that meets the Intel SFX 12V V4.0 specification.
Is the fan completely silent at low loads?
The 92 mm FDB fan can deactivate entirely, delivering 0 dBA minimum noise until the internal temperature rises enough to require active cooling.
