FSP VITA GM 1000W ATX3.1 Power Supply Review

FSP VITA GM 1000W ATX3.1 Power Supply Review

Final Thoughts

If you’re already running a high-quality Hydro G Pro or Hydro PTM model, there’s no urgent need to upgrade; those units are still excellent. However, for builders moving up from FSP’s more budget-oriented lines or older 80 PLUS Bronze or Silver models, stepping into the VITA generation is a solid long-term move.

Introduction

FSP is moving forward with a generational refresh of its PSU lineup, introducing the VITA series as the new backbone of its consumer power supply portfolio. This new series consolidates the company’s once-fragmented Hydro naming scheme into a cleaner, tiered structure. Sitting between the high-end MEGA TI models and the entry-level offerings, the VITA GM line represents FSP’s mainstream, fully modular PSUs designed for current and next-generation hardware standards.

In this review, we’ll be looking at the FSP VITA GM 1000W, a unit rated for 80 PLUS Gold efficiency, but which achieves a Cybenetics ETA Platinum efficiency certification and Lambda A- acoustic performance — a testament to how far FSP has refined its power delivery design. It’s a 1000-watt model intended to provide high efficiency, modern compliance, and near-silent operation for demanding gaming or workstation builds.

Features & Specification

The VITA GM 1000W is built to meet the latest ATX 3.1 and PCIe 5.1 standards, ensuring support for next-generation CPUs and GPUs, including 12V-2×6 connectors with up to 600 W GPU power delivery. FSP’s long-time expertise as an OEM manufacturer is evident here — the company continues to design and produce its own internal platforms, rather than rebadging third-party designs.

Key Features:

• ATX 3.1 & PCIe 5.1 compliance with native 12V-2×6 connector
• 80 PLUS Gold and Cybenetics ETA Platinum / Lambda A- certified
• Fully modular cable design with all-black sleeved 16 AWG cables
• LLC resonant converter topology with DC-DC regulation
• 100% Japanese electrolytic capacitors for long-term reliability
• Semi-fanless operation with 120 mm fluid-dynamic bearing fan
• Comprehensive protection suite: OCP, OVP, SCP, OTP, and OPP
• Global 10-year warranty

Closer Look

FSP ships the VITA GM 1000W in a clean, minimalist black box that mirrors the new direction of the series. The packaging emphasizes clarity over flair — product image upfront, efficiency and the 80 PLUS ratings badge  displayed prominently, and key feature icons along the sides.

Inside, the PSU is securely foam-padded, with a separate pouch for modular cables and a basic manual. Cable quality is solid — the flat ribbon design helps with airflow and ease of routing, while the 12V-2×6 is sleeved and feels notably robust. All connectors are clearly labeled, and the overall cabling layout is intuitive for both mid-tower and full-tower setups.

The PSU itself follows a familiar FSP industrial design: matte black coating, honeycomb rear grill, and subtle embossed VITA branding on the side panels. The fan intake uses a circular grill with a centered logo badge — simple, practical, and easy to match with most build themes.

The modular panel is clearly laid out, with segregated sections for CPU, PCIe, and peripheral outputs. The 12V-2×6 connector sits apart from the traditional 8-pins, making it easier to identify during cable management.

Overall, it’s a confident design evolution — one that prioritizes functionality, thermals, and quiet efficiency over the aggressive stylization seen in gaming-branded PSUs.

Testing and Observation

Test Setup

Processor (LOAD): Intel Core Ultra 9 285K @ Unleashed power limit
Motherboard: ROG STRIX Z890 GAMING-F
Memory: G.Skill TridentZ5 CK DDR5-8200
Storage: Kingston FURY Renegade SSD (OS)
PSU: FSP Hydro GT Pro 1000W
Cooling: Arctic Frozr III 360
Monitor: ROG Strix XG32UQ
VGAs (LOAD): varies by load required, this test: Two(2) NVIDIA RTX 5080
Measurement: Benchlab

We’re currently developing a PSU testing methodology using actual components to generate the load. That said, most modern systems will use the 12V mainly, so I’m currently studying ways to create loads for the 3.3V and 5V that replicate real-world use cases.

Loads are measured inline using either a combo setup of Benchlab or Powenetics v2 with an AC-side load meter prototype. Tests are done in an open test bench for ambient while hotbox test is done by feeding the GPU exhaust to the PSU while enclosed in a box to increase ambient temps. Nothing fancy.

Tests are done in native Philippine outlet voltage of 220V.

Loads are generated by OCCT – Power Test with CPU TDP adjusted for PSU max capacity along with GPU used for testing. OCCT Stability Test is now available directly on Steam for both Windows and Linux.

Thanks to Aris Mpitziopoulos of Cybenetics and Hardware Busters for all the support in our power-related efforts.

Conclusion and Recommendation

The FSP VITA GM 1000W marks a strong step forward in FSP’s lineup refresh. While the company’s older Hydro series remains a reliable option, the VITA line represents the modernization of that legacy — integrating native ATX 3.1 compliance, PCIe 5.1 support, and higher-efficiency platform refinement.

If you’re already running a high-quality Hydro G Pro or Hydro PTM model, there’s no urgent need to upgrade; those units are still excellent. However, for builders moving up from FSP’s more budget-oriented lines or older 80 PLUS Bronze or Silver models, stepping into the VITA generation is a solid long-term move.

Backed by a 10-year warranty, fully modular design, and Cybenetics-verified ETA Platinum performance, the VITA GM 1000W shows that FSP isn’t just renaming its lineup — it’s redefining its mainstream PSU identity for the next decade.
