Manufacturer description
The EVGA SuperNOVA 1000 P5 is a 1000W, 80 PLUS Platinum power supply built for high-draw GPU and CPU pairings that need headroom without a sprawling chassis footprint. At 92% or higher efficiency under typical loads, it wastes less as heat, which keeps case temperatures and fan noise down during long sessions. The fully modular cable set lets you run only what your build needs, so airflow stays clear behind the motherboard tray and in front of the intake. Internally, EVGA specifies 100% Japanese capacitors and an Active Clamp plus DC-DC converter design aimed at tighter 3.3V and 5V rail…

Frequently Asked Questions
Is 1000W enough for an RTX 5090 or 4090 build?
1000W is the wattage class most high-end single-GPU builds are specified around, and this unit delivers it at 80 PLUS Platinum efficiency. Check your specific GPU's recommended system wattage and connector requirements on the manufacturer listing before ordering.
Will the EVGA SuperNOVA 1000 P5 fit in my case?
The chassis is a compact 150mm deep, which is shorter than many 1000W units and fits mid-tower and smaller ATX cases. Confirm your case's PSU clearance spec, especially if you route cables through a basement shroud.
How long is the warranty on this power supply?
EVGA covers the SuperNOVA 1000 P5 with a 10 year warranty. Registration and transfer terms vary, so check the current warranty details on the product listing before you buy.
Is this power supply quiet under load?
It uses a fluid dynamic bearing fan plus EVGA ECO Mode, which holds the fan stopped at low and medium loads for a silent idle.
What is the Power ON Self Tester included in the box?
It is a small jumper tool that lets you power the supply outside a system to confirm the unit spins up before you install it. EVGA includes it with the 220-P5-1000-X1.
