The EVGA SuperNOVA 1000 G6 vs Seasonic PRIME TX-1000 Black Friday 2026 comparison comes down to value versus efficiency: both are fully modular 1000W power supplies, but the EVGA model uses 80 PLUS Gold certification while the Seasonic model carries 80 PLUS Titanium certification. The right pick depends on your build, priorities, and the Black Friday deal you find.
I researched and compared specs, reviews and owner feedback for these two units and six alternatives. My pick for most people is a current-generation 1000W model with a native GPU power cable if a new graphics card is part of the build. For older systems, the EVGA SuperNOVA 1000 G6 remains a compact, well-equipped choice.

- Compared rated output and efficiency certification, with a focus on 1000W models suitable for high-performance gaming PCs and workstations.
- Checked connector standards and included GPU power cables to distinguish older designs from ATX 3.0-era options.
- Reviewed physical dimensions, fan behavior features, warranty terms, and modular cable layouts for practical build compatibility.
- Researched and compared specs, reviews and owner feedback rather than relying on a single benchmark or retailer listing.
- Favored products with clearly identified model variants and manufacturer specifications that make side-by-side shopping straightforward.

Which is better, the EVGA SuperNOVA 1000 G6 or Seasonic PRIME TX-1000?
Both supplies deliver 1000W and are fully modular. The EVGA SuperNOVA 1000 G6 has 80 PLUS Gold certification and a compact 150mm depth. The Seasonic PRIME TX-1000 has 80 PLUS Titanium certification and a 12-year warranty.
Choose EVGA for limited case clearance or conventional PCIe GPU cables. Choose Seasonic for higher efficiency and a longer warranty. For newer GPUs, check each model’s included cables; an ATX 3.0 or ATX 3.1 unit may offer a more direct fit.
Does a 1000W power supply suit a gaming PC?
A 1000W supply suits high-end gaming systems and builds with planned upgrades. The PC draws power according to its components and workload, not the PSU’s full rated capacity at all times.
Check the graphics card maker’s recommended capacity, then account for the processor, storage, cooling, and upgrades. Smaller systems often need less. Verify GPU, CPU, and motherboard connectors, plus case dimensions, before buying.
Which 1000W PSU is best for a newer graphics card?
The Corsair RM1000x 1000W Fully Modular ATX Power Supply (2024), MSI MPG A1000G PCIE5, and Seasonic VERTEX GX-1000 list current GPU power connections. Match the included cable to the graphics card and confirm the exact model’s specifications.
The EVGA SuperNOVA 1000 G6 and original Seasonic PRIME TX-1000 lack the same native GPU cable options. Check for a manufacturer-approved cable solution before choosing either for a newer card.
Is Titanium efficiency worth choosing over Gold?
80 PLUS Titanium ranks above Gold in efficiency certification. The Seasonic PRIME TX-1000 is the Titanium option here; the EVGA SuperNOVA 1000 G6 and Corsair RM1000x are Gold-certified alternatives.
Efficiency ratings describe power conversion under specified load conditions. Consider system use, fan behavior, warranty, capacity, and connectors alongside the certification.
What should shoppers compare for Black Friday 2026?
Compare the exact model, GPU cable, efficiency rating, warranty, dimensions, and return policy. Check the manufacturer model number and included-cable list; product variants can differ within the same family.
Confirm case fit, component connectors, regional warranty coverage, and cable compatibility. Use only cables approved for the exact PSU, and compare newer models when GPU cabling matters.
Buying Guide
Match wattage to the components
Check the graphics card’s recommended capacity and account for the processor, drives, cooling, and upgrades. High-performance builds suit 1000W; smaller systems often need less.
Check GPU power connectors
Match the card’s connector to the included PSU cable. Verify the exact model and manufacturer guidance before using an adapter or replacement cable.
Confirm case fit
Check the PSU bay and cable-routing space against manufacturer measurements. The EVGA SuperNOVA 1000 G6 is 150mm deep.
Compare efficiency and warranty
Compare certification and warranty with the system’s needs, connectors, and capacity. Neither rating alone determines the best fit.
Verify the exact listing
Use the full model name and manufacturer part number to confirm standards, cables, accessories, and return terms.
FAQ
EVGA SuperNOVA 1000 G6 vs Seasonic PRIME TX-1000: which should I buy?
The EVGA SuperNOVA 1000 G6 is the practical choice for compact dimensions and Gold efficiency, while the Seasonic PRIME TX-1000 is the premium pick for Titanium efficiency and a 12-year warranty. Check GPU cable requirements before choosing either older-platform supply.
Is 1000W enough for a high-end gaming PC?
A 1000W PSU is enough for many high-end gaming PCs, but the exact answer depends on the graphics card, processor, and other components. Check the GPU manufacturer's power recommendation and leave suitable headroom for upgrades instead of relying on wattage alone.
Does the EVGA SuperNOVA 1000 G6 have a 12VHPWR cable?
The EVGA SuperNOVA 1000 G6 1000W 80 PLUS Gold Fully Modular Power Supply does not include a native 12VHPWR cable in its original configuration. Buyers using a newer graphics card should verify a compatible manufacturer-approved cable solution before purchase.
Does the Seasonic PRIME TX-1000 support PCIe 5.0 graphics cards?
The Seasonic PRIME TX-1000 can power a compatible graphics card when the system has the correct supported cable, but the original model does not include a native 12VHPWR cable. Check the GPU and PSU manufacturer instructions and compare newer ATX 3.0 alternatives.
Which is quieter, the EVGA SuperNOVA 1000 G6 or Seasonic PRIME TX-1000?
Both models include fan-management features, but noise depends on case airflow, room temperature, system load, and fan profile. Compare owner feedback for the exact model revision and check the manufacturer's fan-mode specifications rather than treating efficiency certification as a direct noise rating.
Is the Seasonic VERTEX GX-1000 a better alternative to the PRIME TX-1000?
The Seasonic VERTEX GX-1000 is a better fit for a new build needing ATX 3.0 support and a native 12VHPWR cable. The PRIME TX-1000 is the better match for buyers prioritizing Titanium efficiency. Choose by GPU connection, efficiency preference, and system requirements.
