EVGA SuperNOVA 1300 P+ 1300W Power Supply: features, specs and fit

The EVGA SuperNOVA 1300 P+ (model 220-PP-1300-X1) is a 1,300-watt internal power supply for desktop PCs. It sits in the P+ line, which EVGA describes as fully modular with Platinum-level efficiency. It is aimed at powerful gaming and workstation builds. Below is what the main features mean and what to check first.

What 1300W of capacity means

The wattage on a power supply is the most it can deliver to your components, not what the PC pulls all the time. Most systems idle and work well below that figure. A 1300W unit is typically chosen for builds with a high-end graphics card and a powerful processor, or for people who want room to add parts later.

A sensible way to size a supply is to add up the rated draw of the processor, graphics card, drives and fans, then leave a margin. Your graphics card maker's recommended supply wattage is a useful cross-check.

80 PLUS Platinum efficiency

EVGA lists the unit as 80 PLUS Platinum certified, with 92% efficiency or higher under typical loads. The 80 PLUS programme tests how much of the power drawn from the wall reaches the components and how much is lost as heat. Platinum is a high tier.

Higher efficiency generally means less waste heat, which the fan has less work to remove, and a lower draw from the wall for the same output.

Fully modular and a cleaner layout

Fully modular means every cable plugs into the unit and can be left out. You attach only what your system needs. EVGA says the P+ range has a cleaner internal layout to increase airflow, and the modular cabling helps case airflow too, since fewer loose cables sit in the way.

Voltage stability and protection

EVGA describes several design points:

• 100% Japanese capacitors.
• A DC-DC converter design to improve 3.3V and 5V stability.
• A Variable Resistor module to increase voltage stability.
• Two DC-to-DC modules for more efficient power switching.
• A full suite of power supply protections.

In general terms, DC-DC designs make the lower voltages from the main 12V rail, which tends to hold them steadier when the load changes. The manual lists exactly which protections are included.

Fan and ECO Mode

The fan uses double ball bearings, which EVGA says supports ultra-quiet operation and longer life. ECO Mode is EVGA's setting for lower fan noise. Check the manual for how it is switched on and how the fan behaves at light loads.

Warranty and weight

EVGA offers a ten-year warranty on all P+ supplies, and the listing gives the weight as 9.0 lb (about 4.1 kg). The listing does not give dimensions, so check EVGA's specification sheet for the length before choosing a case.

Who it suits

It suits enthusiast and workstation builds that need a lot of power, plus people who value tidy cabling and a long warranty. Smaller systems with a single mid-range graphics card typically need less capacity.

What to check before you buy

• Case fit: confirm the supply's length against your case's ATX power supply space, including cable room.
• Power need: add up your components' draw and compare with the graphics card maker's recommendation.
• Connectors: make sure the included cables cover your graphics card and motherboard sockets.
• Mains outlet: a high-wattage supply can draw a lot at full load, so check the circuit.
• Noise: consider how the fan behaves at your usual load.
• Warranty: read what the ten-year warranty covers and how to claim.

The short version

• A 1300W ATX power supply, model 220-PP-1300-X1, from EVGA's P+ line.
• 80 PLUS Platinum certified, with 92% efficiency or higher under typical loads.
• Fully modular, with Japanese capacitors and a DC-DC design for 3.3V/5V stability.
• Double ball bearing fan and ECO Mode.
• Ten-year warranty; 9.0 lb as listed.
