The Enermax 1020W power supply arrives in an attractively designed box which is very understated.
Opening up the main outer box we are presented with two smaller packages, one contains the modular cables and felt based cable ties and the other the power supply itself with manuals and other information.
The bundle is comprehensive, Enermax ship a felt pouch to store unused cables and they also supply literature detailing the unit as well as other products in their range. We are quite pleased to see the inclusion of a 120mm case fan which is LED based. There is also a little clip which Enermax are calling ‘CordGuard' – to protect the cable from being easily removed.
There is a sticker included as well as 4 screws to mount the PSU inside a case. We are pleased to see a UK plug included with this unit rather than a european model we often see bundled. The power supply is modular based and all of the cables are colour coordinated to ensure correct fitting. The majority of them are braided sleeve design which is good to note.
Both 920W and 1020W models are shipped with the same amount of cables as can be seen in the table above.
The Revolution 85+ has remained true to the previous design ethic – a beautifully finished, graphite coloured chassis with a smooth red accent around the fan area at the top. The PSU is 17.5x15x8.6cm and weighs 2.4kg (50g more with modular cables all connected).
The rear of the PSU features a power on/off switch, 3 pin power connector socket and a large grill to allow for the passage of air.
The graphite rear is home to a sticker which details the specifications of the supply.
| Model/DC Output | +3.3V | +5V | +12V1 | +12V2 | +12V3 | +12V4 | -12V | 5Vsb | Peak Power | Total Power |
| ERV1020EWT | 24A | 24A | 35A | 35A | 35A | 35A | 0.5A | 3A | 1120W | 1020W |
| 120W | 1020W (85A) | 6W | 15W | |||||||
Each of the four 12V rails can deliver 35A.
The native wiring on the rear is braided – the connectors are 24 pin, two 12V CPU (1×8, 2×4) and two 8 pin PCIe connectors. There are only a handful of connectors here which is good to see, as the majority of the connectors are focused on the modular section to the right.
Another great PSU, nice to see something else outside Corsair here this month 🙂 Tough competition for Enermax, this would have been leading the way 6 months ago.
Interesting to see the 12V mv fluctuation. clearly some circuitry changes have taken place since the last models were released. looks great however
Very tough market now with corsair dominating. Still this is a brilliant model, but the price needs to drop to under £200 to be truly competitve. Nice to see Kitguru being totally honest. i saw another review of this last week (or another model) on a tech site and they give it a top award. I fail to see how this really deserves to be put before the corsair unit considering the performance, efficiency and price differences.
The corsair Flextronics models are totally unbeatable right now until other manufacturers catch up. While this Enermax model is certainly worth buying, it shows the gulf in design between the last generation and this new cutting edge flextronics generation.
I agree. I read a review of this on johhnyguru and it was honest. a few other sites seem to have been overly supportive of this unit. the 12v mv is a little concerning, while it wont cause issues, it still shouldnt be there and compared to the AX1200 which is 15 less, produces more power, more efficiency with more stability with mv, it seems a no brainer. still enermax deserve some credit, I dont want to appear dismissive.
great testing, glad to see you raised ambient temperatures by 10c to cover a greater variety of system temperatures. 25c was too low.
Very good review and I think this is a great unit. I agree Corsair is number 1 choice, but this is a close second.
Great testing KitGuru, best review of this unit ive read online yet,
Good solid design, nice to see rubycon components, those are wiked good/
This is still extremely hard to buy, hacent seen it anywhere 🙁
been trying to buy this for weeks, still cant find it anywhere. Enermax need a new distributor.
They look really brilliant, the design is awesome and im so glad they aren’t using gold fans in this model.
£250 is too much for this, its not competitve. not thanks to corsairs new AX models. I would score it 7/10 for this alone.
Great testing, good to see ambient temperatures up. would still like to see them at 50c however. good step up however.
Efficiency is good, not quite as good as AX series from corsair, but if you have an issue with corsair as a company on some level then this seems to be the one to get.
Zardon, no offense, but how did this get 8.5/10? the testing is spot on, I have one and have taken it apart too. however, the 12V mv is quite movable by todays standards which could in theory cause an issue under full load with for example 2 480’s GTX in SLI. Not only that, but the price is £250, which is £15 more than the AX1200 from corsair which is more powerful, more efficient and doesnt suffer from 12 mv fluctuation. Views?
Garth, this power supply wont give issues with 2 480GTXs under load. dont be silly. the 12 V mv result kitguru measured is STILL well within the recommended specifications by industry experts. Certainly wont argue the corsair units are better, but lets keep it sane !
Great review, very helpful. I need to get the AX1200 now, thats my view !
No one needs this, or the AX1200. the AX850 is the best PSU on the market now when taking into consideration the price point and current modern hardware requirements.
Nice design, always loved the appearance of these products. just a shame they werent comparible to corsairs. makes the pricing seem even more ridiculous.
Found this review today and had to say great site ! very good testing and nicely laid out with high quality pictures.
GREAT REVIEW ! ill be back.
Very nice indeed, Enermax are quality. id rate them higher than corsair due to their history in this market and 5 year warranty.
Dont corsair offer a 5 year warranty also ?
@ Trev, I’m pretty sure Corsair actually offer a 7-year warranty on their PSUs…
I lost all interest in Enermax when I bought Galaxy 850W with that stupid Power Guard system, beeping every step of the way without any reason (even if UPS was well above specified data – 850W PSU require at least 1000W UPS to work properly, I have 1980W). I was using Liberty 500W for a long time then switched to Galaxy and it was biggest mistake of my PC buys. Switched once more but this time to Corsair and never looked back. Enermax messed up big time with first versions of Galaxy and Revolution. For me never again Enermax. It is good to see that this “big-success” addition Power Guard is… no more with this particular model.
Furthermore at this price point I expecting fully modular construction. It is not a secret that Enermax’s sleeving and connectors are rather poor and bulky. Cables are not as flexible as Corsair, with Enermax you need often excessive force to plug another 12V line cable, while Corsair connectors just slid in, do “click” and end of story. For now using spare Galaxy 850W on test bench with minimum loads mainly to test old HDDs with various controllers.
Best buys today are:
– (Blue) 750W Corsair – if you don’t need fully modular setup or SLI/CF
– (Gold) 850W Corsair – if you do require fully modular PSU and SLI/CF
– (Gold) 1200W Corsair – if you don’t want to buy PSU for another 5 or even 10 years.
Right now Corsair is simply unbeatable. Best quality, best price, best design (talking about cables, connectors and general ease of use not color of the box) and finally best support with 7 year warranty.
Thanks for sharing your info. I truly appreciate your efforts
and I am waiting for your next write ups thanks once again.
