Manufacturer description
The EVGA SuperNOVA 1300 G2 is a 1300W fully modular power supply built for multi-GPU rigs and high-draw workstation builds. It carries 80 PLUS Gold certification, delivering up to 90% efficiency under typical loads, so less of your wall power turns into waste heat inside the case. Cooling comes from a 140mm double ball bearing fan, a longer-lived choice than sleeve bearings in systems that run hot for extended sessions. EVGA covers the unit with a 10 year warranty, which is unusual longevity for a PSU and means it can carry through two or three GPU upgrade cycles. The protection suite is…

Frequently Asked Questions
Is 1300W enough for a dual RTX GPU build?
The 1300 G2 is rated NVIDIA SLI and Crossfire ready, so it is spec'd for dual-card setups. Add your exact GPU and CPU TDPs and confirm against the wattage table on the product listing before ordering.
How long is the warranty on the EVGA SuperNOVA 1300 G2?
EVGA lists a 10 year warranty on this unit. Check the product listing for current registration requirements and regional terms.
Can I use my old modular cables from another power supply?
No. EVGA states explicitly that you should use the cables included with the product, because third-party cables can cause the system to fail to power on. Pinouts differ between manufacturers.
What efficiency rating does this power supply have?
It is 80 PLUS Gold certified, reaching up to 90% efficiency under typical loads. That means roughly 10% of drawn wall power is lost as heat at mid-range utilization.
Is this power supply reliable enough for a 24/7 system?
It uses a 140mm double ball bearing fan, which tolerates continuous operation better than sleeve bearings, and carries OVP, UVP, OCP, OPP and SCP protections.
