OPEN BOX - Evga SuperNOVA P3 1000W Power Supply

I must say, this is an impressive power supply from EVGA backed with their 10 year manufacturer warranty. It's compact and reliable and easy to work with due to the modular nature of it. For comparison, it is also quite the big improvement from the previous generation, the P5, which I've previously owned before which had some troubles with it due to it struggling with consistent power delivery (I would get really weird issues like my video signal cut off with a black screen due to the GPU with the transient spikes). Once I upgraded to the P6, my troubles vanished and I could use my PC without worry. I must mention though, The P6 generation is built by the OEM, Seasonic, which is surprising to be honest but they are reputable with their hardware and specifications. As to the P5, the OEM is FSP, which I found to my research from that PSU they are not that great. I threw some power benchmarks such as OCCT on and see if it holds up to max power, with the context of using an RTX 3080 and R7 5800X3D for many hours. Surprisingly it does hold up stable and no crashing, quite strong. Noise level is pleasant, not distracting. I do suggest keeping ECO Mode switched to OFF for longevity because cooling is necessary. Overall, I feel very happy that this power supply holds up and does the job well, and I certainly will be at ease with EVGA's backed 10 year warranty if this power supply needs it. Definitely would recommend.

I have 5 spinning drives in my NAS and was getting errors constantly about one (or more) of my drives not being available. Reboot fixed it so I thought it was the software, reinstalled it and same problem. Bought this PSU, not expecting much, and problem solved. My old PSU is a name brand, "high quality" unit but this one is way better.

Had it over one year, still works and no issues.

I got this to upgrade from a Corsair PSU, and its worked flawlessly for 7 months since I got it with heavy daily usage.

MAJOR FAIL - No photo of the Modular Panel in the Manual!!!! With PC OFF, I can't go online to see where the SATA modular ports are on the PSU!!! PUT a photo in the booklet!! That said, this unit is super QUIET with ECO off. PSU = Fast and snappy!! Rock Solid!!!!!! Running 1 x 10 TB drive + 4 x 500GB SSD internal + one 10 TB + 4 x 2 TB external. CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz. RAM: 32.0 GB. Built my PC. Do Audio / Video Production.
