EVGA SuperNOVA 1300 G+ (1300W/80+ Gold/ATX 2.x/Flagship Extreme Tier) Review

EVGA SuperNOVA 1300 G+ 1300W 80 Plus Gold fully modular power supply, ATX 2.x certified, ATX form factor, standard PCIe connectors, 10-year warranty, Super Flower platform.

The EVGA SuperNOVA 1300 G+ is a high-wattage Gold-rated unit for older-generation multi-GPU or heavy workstation builds that need eight native PCIe connectors without paying for Titanium. Rated 1300W at 80 PLUS Gold (Cybenetics Gold efficiency / A noise), it's built on a Super Flower platform with a 135mm fluid dynamic bearing fan running a zero-RPM semi-passive mode at idle. Fully Modular cabling and a 180mm chassis depth make it a realistic fit for a workstation or multi-GPU build with serious headroom, and it's backed by a 10-year warranty.

Efficiency, Noise, and Build Quality

The SuperNOVA 1300 G+ carries an 80 PLUS Gold certification and a Cybenetics Gold efficiency / A noise rating, translating to consistently high real-world efficiency at typical 50% load and low fan noise thanks to its 135mm fluid dynamic bearing. It uses a Super Flower platform with Japanese-made capacitors throughout for long-term reliability under sustained load.

Connectors and Cabling

Connector layout is 1x 24-pin ATX, 2x EPS 4+4, 8x PCIe 6+2-pin, 10x SATA, 4x Molex. It relies on traditional 6+2-pin PCIe connectors, so an aftermarket or bundled adapter is needed to power a 12VHPWR/12V-2x6 GPU natively. Cabling is fully modular, using standard flat or ribbon cables, with a single +12V rail design .

Comparison to Alternatives

Against the EVGA SuperNOVA 850 G6 (EVGA's compact 850W Gold value pick), the EVGA SuperNOVA 1300 G+ matches its wattage class but differs on connector generation and OEM platform, making the choice mostly about brand ecosystem, warranty length (10 years here), and whether native PCIe-only connectors matter for your GPU. Compared with the MSI MAG Ai1600TS PCIE5 (MSI's 1600W Titanium workstation flagship), the SuperNOVA 1300 G+ sits in the flagship extreme bracket at 1300W, so the decision usually comes down to matching wattage headroom to your actual GPU/CPU combo rather than one being categorically better.

Expert Review

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating8.3 / 10

A solid 1300W Gold-rated ATX unit for a workstation or multi-GPU build with serious headroom, held back only by the usual mid-tier compromises on cabling and OEM sourcing.

Best for

  • Builders targeting a workstation or multi-GPU build with serious headroom
  • Anyone who wants fully modular cabling with standard PCIe connectors
  • Systems where a 10-year warranty and Gold-tier efficiency matter

Not for

  • Builds needing more than 1300W of continuous headroom
  • Buyers who need the smallest possible SFX/SFX-L footprint
  • Cost-sensitive builds better served by a lower-tier 80+ Bronze unit
