Question

Enermax 85+ 920W OR Seasonic M12D 850W

Sep 13, 2015 2:35PM PDT

Hello all. I am going to be purchasing a new power supply and have come across a deal for the two PSU's listed above. I will be buying them in a private sale but they have been listed by the seller as brand new in box. Assuming this is true, they seem to be very comparable. They are both the same price so my primary concern here will be reliability. These models are dated and therefore I am getting a second hand sale without warranty, so I want to buy the one which has a better chance of being reliable.

They both have been given amazing ratings: Both silver rated. The Seasonic carries the advantage of being one of the most reputable brands, whereas the Enermax has been touted by many as a top of the line PSU.

Does anyone have an opinion on which one i should get? As I am very new to computer hardware. Please and thanks!

Knowledge how to balance +12V rails, remove units with multiple +12V rails. I don't see a link to the maker's web page so I'll share what I look for.

1. Single +12V rails when I don't have time to check out the amperes per rail and my build.
2. POUNDS. Tomshardware a long time ago made an interesting observation. The PSUs with the higher weights fared better in full load testing.
Note: Corrected typo in title.

Weights and Rails
Sep 13, 2015 3:23PM PDT

Enermax 85+ 920W
Product weight - about 5.3 lbs
12V rails - 4

Seasonic M12D 850W

That being said I won't be running anything too heavy. Just concerned about durability in the long term.

Quad rails are to be avoided

I've lost count of folk that can't make it work in spite of running something heavy or light. No sale for the quad rail.

Brands?

As per the manufacturer, would you have a preference between the two? I intend to spend some time researching the appropriate set up for the rails, so I am more concerned about the actual model and product quality.

Since I only have these choices.

The dual rail wins. It also weighs more which was a good thing noted in Tomshardware in a prior discussion.

Again, the quad rail is so hard on first time builders that it's not to be considered.
