ATX 3.1 Titanium 1000W power supply

The FSP HTI-1000M delivers 1000 W of continuous power in an ATX 3.1 compatible form factor. It targets builders who need high efficiency and full modularity for modern graphics cards and CPUs. The unit carries 80 Plus Titanium certification and a Cybenetics Lambda A++ noise rating.

PCIe 5.1 12V-2x6 connector support

The power supply includes a native 12V-2x6 connector rated for PCIe 5.1 power excursions. ATX 3.1 allows transient spikes well above the nominal 1000 W rating, so the platform must handle short bursts without shutdown. Cable length and routing remain the installer's responsibility.

Replaces older ATX 2.x or non-modular units

Upgrading from an ATX 2.x design removes the need for adapter cables and adds the 12V-2x6 interface required by current GPUs. The jump is worth it when the existing unit lacks native PCIe 5.1 support or cannot sustain high transient loads. Fully modular cabling also reduces clutter compared with fixed-cable models.

Questions about this item

Should I pick the 1000W unit or look for a higher wattage model?

The only model listed is the 1000W unit rated at 1000W total power with 83.33A on the +12V rail, so choose this capacity if your build needs up to 1000W.

What does the 1000W rating deliver inside a real PC?

It supplies up to 1000W total with 83.33A on the +12V rail, 20A on +3.3V and +5V combined to 120W, 0.3A on -12V and 3A on +5Vsb, all at 94% typical efficiency.

How does the ATX 3.1 and PCIe 5.1 interface limit power spikes?

The PSU meets ATX 3.1 and PCIe 5.1 excursion requirements and includes a 12VHPWR connector, so it handles the transient spikes those standards define for modern GPUs.
