Top Notch PSU

Item arrived as described and was packaged very well. I ordered the 1200W for some future proofing in my PC and glad I did. There are so many extra cables and connections available to where it truly lives up to being modular. This PSU works fantastic and I am very happy with my purchase.

Solid PSU

A 650W 80+ Gold for roughly $40 is quite the steal. No complaints, no issues.

Solid PSU!

This is a very solid and capable power supply that will last for many years to come. It will occasionally make a few clicks prior to turning on, but it seems this is normal for high end PSUs due to mechanical rail switches inside. Remember to register yours through EVGA for a 2 year warranty extension!

EVGA PSUs have the best quality, warranty, and cable management

EVGA PSUs are the best: great quality, great warranty, and great cable management. I went for the 1200W P2s because I needed the power and 6 VGA connectors. I typically buy the EVGA Gold PSUs, but I went for the Platinum for improved efficiency. I switched to EVGA PSUs after I had several failures with cheaper competitors, and would rather purchase a single quality PSU than multiple cheap PSUs for the duration of my PCs lifetime. I like how the different class of EVGA PSU cables all have the same connector. I like how the cables that came with my EVGA 1000W G5 are marked "G5", but I wish that had done the same for the "P2".

Very happy,very quiet

I don't have a power hungry system right now so I have it in quiet mode. The fan doesn't even bother turning on, and you don't get quieter than that. When I can get some more power hungry components I'll probably switch it to normal mode. I'm happy to have plenty of room for growth with this PSU.

Best 1200w PSU Out There!

Best 1200w PSU out there at a great price! Plenty of power at a high efficiency. EVGA makes such high quality parts and offers a 10 year warranty on on this product. Both the cables and the PSU even came in nice, branded, bags. Would recommend this to anyone.

Good Stuff

This thing is great. It's powering (3) RTX 3080 GPUs with ease. I put one PCIe to each port on the graphics card, 6 outputs and 6 inputs. There's also enough connectors for one each to the GPU riser cards. Really the perfect power supply for an RTX 3080 rig.

EVGA PSU FTW

Wonderful power supply. I bought this for my GPU mining rig. It comes with a plethora of cables. I also really like the finish on the outside. It has that rugged truck bed liner finish so you know it will be able to withstand the occasional bump here and there. They should start branding these PSUs "FTW" like their GPUs.

Amazing and quiet and rock solid power

I have an EVGA 650 and it is amazing. But when I got a new GPU, CPU, RAM, etc., I needed an upgrade. Yes, PC sites will tell you the minimum you need, but NEVER get the MINIMUM! You need head room and there are spike especially when loading, so when you think of your PC, do not skrimp on the PSU. Spend the money to buy quality. You won't regret it.

Great PSU

Great product and easy to work with. First time building with it. Powers my 3080 and 5900x without skipping a beat. Probably overkill for my build but I got a good deal on it. Only downside is the ac power cable is a bit short for my setup and had to buy a longer chord to work with my setup and cable management OCD

The best power supply I've ever had

This powersupply is handling my build with EASE and it is begging for more >1kw consisting of 2700x and 2080ti x2 OC Custom Watercooled. Excellent power supply. Too bad prices are so outrageous right now.
