1000W ATX 3.0 server power supply

The Hoengager GF3-1000W is a new single-unit server power supply rated at 1000W maximum power. It meets the ATX 12V v3.0 and EPS v2.93 standards and carries an 80 Plus Gold efficiency certification. A 135 mm hydraulic bearing fan provides cooling. The unit is fully modular with a 24-pin main connector included.

Suited for high-output ATX 3.0 builds

This unit suits builders assembling systems that require the ATX 3.0 power standard and a 1000W Gold-rated supply. It is not for buyers who need a redundant power configuration or a form factor other than standard ATX. It also does not fit builds that demand a lower or higher maximum wattage than 1000W.

Handles +12V loads up to 83.5A

The +12V rail delivers up to 83.5A while the +3.3V and +5V rails each provide 22A. The +5VSB rail supplies 3A and the -12V rail supplies 0.3A. These ratings give headroom for multi-GPU arrangements and dense storage arrays. The supply runs out when continuous draw exceeds 1000W or when any single rail hits its stated ampere limit.

Questions about this item

What motherboard power connector does the GF3-1000W require to operate?

The unit uses a 24Pin main connector that plugs directly into an ATX 12V v3.0 or EPS v2.93 compatible motherboard.

Can I keep using my existing 8-pin PCIe cables with this power supply?

The GF3-1000W is fully modular; you must use the cables supplied with it, which include a PCIe Gen.5 12VHPWR connector for modern graphics cards.

How can I verify the GF3-1000W is delivering stable power after installation?

Check that the 135 mm hydraulic bearing fan spins and that the system boots without triggering OCP, OVP, UVP, OPP, SCP or OTP protections.
