Enermax Revolution85+ 950w Modular PSU
In the world of PSU's its very rare to come across a unit that 'does it all'. Some have extremely solid rails, but tend to be based on industrial units and are therefore noisy. Others are extremely cool and quiet, yet fail to achieve tight voltage regulation when placed under heavy loads. Some look the part, but don't play the part. And others simply fail at everything.
However, glancing back over the previous few pages it's really quite hard to find fault with the Enermax Revolution85+. Not only does the unit look the business, but it means business too. 90%+ efficiency was effortlessly achieved across almost all load levels with 94% efficiency even being seen during one of the cross-load tests. Noise output was minimal with the unit managing to stay whisper quiet even when placed in our 50°C hot box and made to deliver more than its rated output, and the operation temperature of the unit was so low that in most cases it barely added to the ambient temperature.
Voltage regulation was also extremely good with the Revolution85+ exhibiting no signs of crumbling under the strain of our load tests, even when placed in extreme and unrealistic cross-loading situations. In fact much to my astonishment, the Revolution actually seemed to thrive on these tests, putting out better results than in some of the normal load tests! This combined with the exceptional ripple results seen on the scope certainly shows that Enermax's 19 years of experience has been put to good use.
There are however just a few small things that prevent the Revolution85+ from being absolutely perfect...
First of all, and probably most annoying for those who dabble in the dark art of cable tidying, is the crude and rather ugly splitting of some of cables a good 15cm after they have exited the unit. Should you for example only want to use one of the hard-wired PCI-E or EPS12v connectors then the other cannot simply be bundled up and hidden under/behind the unit. This may sound trivial in the grand scheme of things, but unless Enermax made a cock-up in the design of the hard wired connectors, there should be absolutely no reason for this cable split .
Of course, matters are only made worse by the use of the gold woven sleeving. Granted Enermax probably have stockpiles of the stuff coming out of their ears, but for a unit that costs just shy of £200, is some sleeving that matches the Red and Black theme used on the rest of the unit too much to ask?
And finally...still on the subject of cables, we come to the Molex conspiracy! Why on earth Enermax thought it necessary to include 12 SATA and only 6 Molex connectors is beyond me. Molex is still very much the predominant standard, especially considering that it has a much wider range of uses. 8 of each would have been a much more sensible choice.
- 90%+ Efficiency at most load levels.
- Silent operation. Even when running at 50°C with a 976w load!
- Cool running temperature. Exhaust temps were often equal to or below intake temps.
- Great scope results.
- Red + Black colour combination looks the business!
- Plenty of PCI-E cables with scope for plugging in even more.
- Safety features galore!
- Stable voltages.
- Price. Higher than most (all?) other units on the market.
- Gold woven cable sleeving. Needs to be Red damnit, RED!
- Negative 12v rail quite low.
- Too much SATA, not enough Molex.
- Some cables look like they've been shoddily spliced.
