The Enermax NAXN 850W is a well rounded power supply which offers high power output at a very respectable price point. Technically, the design is good, you are given solid 80 Plus Bronze efficiency with a very stable power delivery which held well across many days of intensive stress testing.
The NAXN 850W scores high with load regulation, ripple and efficiency and it doesn't generate a lot of noise either, which will appeal to gamers who are trying to ditch an older, less efficient power supply.
On a design level – we like the appearance. Some of the Enermax power supplies can look a little gaudy at times, but the subdued paintwork and gold fan grill will look attractive within any system build. The modular cables are high quality and sleeved, with a fantastic and clearly coded modular layout on the chassis to ensure that even inexperienced system builders don't experience any build problems.
When it comes to purchasing an 80 Plus Bronze power supply the decision can often be based around the retail price.
Right now in the UK the Enermax supply costs £120 inc vat, which compares reasonably well against the competition. That said, there are other high quality modular supplies such as the HX 850W from Corsair which cost only £5 more and offers 80 Plus Silver certification. Corsair also have a longer 7 year warranty system, Enermax is 3 years.
In real world terms, this supply has been powering an overclocked Core i7 980X system with two GTX580's in SLI for the last week. The system has been rock solid since we started using it and while the power supply could get warm under extended load we experienced no instability or random crashes, which can happen with a lesser unit design.
The NAXN 850W earns our WORTH BUYING award, it isn't a clear market leader in such a competitive sector, but it is certainly worth shortlisting for your next upgrade.
Pros:
- Price point is competitive
- technically, its a solid design
- modular layout is excellent
- nice appearance
- great build quality
Cons:
- Facing some competition at £120 from other leading units
KitGuru says: A quality product from Enermax.
I always buy enermax, this is my next PSU purchase.
I think thats the same fan that was in the OCZ 1000W PSU I bought years ago. it was quite quiet.
Interesting, especially warranty terms ive been looking into this today and many manufacturers vary from 1 year to 8 years!
Enermax are normally very expensive, this seems slightly better priced
Enermax don’t make it that’s why its cheaper, its their badge just
I have always owned enermax power supplies, they are very reliable.
I am sure others are, but I tend to stick with a company if I get a good experience
This is really nice, and the price is good. shall bookmark it for the summer when I upgrade. unless something else better comes out at 110-120.
