Power packed to the core, the ENERMAX Revolution85+ ERV850EWT 850W power supply is ideal for the ultra high end multi-GPU gaming system. It is SLI, CrossFire and Quad Core CPU ready, and will add real boost to your beast machine. This modular PSU is designed to deliver maximum power with minimum heat. Instead of a small fan on the back of the unit, there is a large 135mm fan on the bottom, and the back panel is a minimally obstructive hexagonal mesh interrupted only by the power connector and switch.

The modular design makes cable management easier. The main power cables are permanently attached while all of the peripheral cables all plug into the back of the PSU. The cables are all wrapped in mesh for a cleaner installation.

Six +12V rails ensure a balanced power output for your system no matter what the load. Six 6+2P (8P) PCI-E connectors is featured for PCI Express 2.0 / DXX next generation graphic cards. Ready for the future, the ERV850EWT features four 12P sockets for possibly upcoming new CPU's and graphics with 10 or 12Pin connectors. With its 80 PLUS SILVER Certified, so less energy is wasted as heat or interference, delivering more power to your hungry system!

  • newegg ATX12V and EPS12V Compatible Compatible with the ATX12V and EPS12V standards, the Enermax Revolution85+ ERV850EWT power supply provides maximum stable power to drive the processors as well as other components for desktop and even sever computer systems.

1 out of 5 eggsSupposed to be great x2

Pros: Still looks nice and feels solid.

Cons: Hooked up to power supply tester before installing (just to make sure) and it bombed. I was shocked! Supposed to be high quality this and uber nice that. This is the second one I have purchased. I can understand one failing once in a while. But two...I'm going with another Manufacturer.

Other Thoughts: Dissapointment. I'm going with a Corsair next time.

Manufacturer Response:

2 out of 5 eggsSupposed to be great

Pros: Looks cool and feels well built. Had 0 problems untill...(see below)

Cons: Fan in unit went kapoot! It sounds like a food disposal. I've got my tower right next to my monitor and it's hard to enjoy games or web browsing with "Brararararararar" ringing in your ears.

Other Thoughts: Had no problems with unit for a few week until fan went out. I really like the look of the case however and will probably send this one back and get another.

5 out of 5 eggsHuge-o-max

Pros: Cr@p load of connection cables. This thing could power a house.

Nice finish and did I mention it came with 10 different cables.

Heavy duty wire bundle.

Cons: Wires a bit to rugged, felt like wrestling a python to get them to fit in my case.

Lots of wires, except 4- 3/2 pin, for fans.

Other Thoughts: This thing is a behemoth. I had to drill hole in my case to mount this thing. Run quiet too.

5 out of 5 eggsvery good

Pros: I'm running x58, 12gb of ddr3, 2x 4890s in crossfire, 1tb hd, 14 fans, this thing is a beast. I'm using all the non modular cables that come with it, and some. This thing is built like an animal. I have it on the bottom of my HAF 932 and it has been flawless since I purchased it and i still have plently of modulars left over for when i upgrade to 2x 5870's

Cons: none so far

Other Thoughts: the texture is real nice, its a ruff sandy kinda texture, and colors go nice with my black/red theme

4 out of 5 eggsCables & Connectors Issue

Pros: My impression is that this is a very high quality power supply. Engineering & assembly are top quality. Too early to evaluate reliability but I expect it to be as good as the 4 year old Enermax Noisetaker it is replacing.

I'm amazed at how cool this power supply runs. I thought this efficiency craze was all hype. I fully admit I was totally wrong. The Noisetaker put out a lot of heat, especially during gaming. The fan is rated for 700-1500 rpm. It starts up at 610 rpm and I have yet to see it go above 810 during gaming. It's very quiet but unfortunately all the other fans I have make that irrelevant.

Cons: On the website and in the manual they show a proper 6 pin plug for PCI-E graphics power. But what they really supply is different. The plugs are really designed for 8 pin sockets. The latch is in the wrong place for the 6 pin socket. At first I thought I'd have to break off the latch but I was able to bend the latch far enough to reach the latching point on the socket on the 8800GT. I'm sure it will break off eventually. The least they could have done was provide one or two of the correct plugs but all graphics power plugs were like this, both the "native" (built in cables) and the modular cables.

I had to buy an extra Molex connector peripheral cable through their parts retailer because the don't supply enough.

On one of those supplied Molex connector cables all 3 connectors were so poorly assembled that the pin sockets were locked at a severe angle within the connector. I had to pry each little connector tube to line up with its pin before pushing the connectors together!

Other Thoughts: Even though the cabling is modular I still ended up with a large bundle of unneeded "native" cables that I had to secure out of the way. I guess someone building a more modern system might use all those cables. After all, this is meant to be a PS for the latest technology.

The reason that I chose Enermax is for the same feature that my 4 year old Noisetaker had. The fan runs for a time after computer shutdown to avoid the sudden heat build right after shutdown. I couldn't find that feature anywhere else. I think all power supplies should have it. This unit has the new status led which I think is helpful. It's so bright that I don't have to peak around the back of the case. It reflects off the nearby wall even in daylight.

5 out of 5 eggsNice PSU

Pros: Modular, Nice build quality, Quite, Good Looking, They say it's actually 90% efficient (how would I know) the box says 80%. Psst, but inside the box they tell you different.

Cons: None so far. Oh, no FDD power cable... You need a $10.00 FDD when eveything else goes to S.... Like both of my optical drives... at the same time... really.

Other Thoughts: If you're not an electrical engineer what intelligent thing can you really say about a PSU... Modular! It's kind of dummy proof. I learned the hard way about inadequate or unbalanced power. You take a cable tree and plug into a circuit. When you use it up get a new tree and plug into another circuit. You don't overload a circuit, you get balanced power. Whatever PSU you buy get it modular, and around 150w more than what you think you need. I've got a "simple" rig that calcs out at 730w, who knew. It came with a 550w Antec.

5 out of 5 eggsvery Sturdy

Pros: 1. Very well built and heavy duty
2. 850 watts (perfect for my 2x 4890's xfire setup)
3. Color combination and design is sleek
4. the texture is rough which makes it unique
5. fits well on the bottom of my HAF 932 case with fan facing up
6. wire management is a charm

Cons: none so far

Other Thoughts: didn't include this as a con but i ran out of regular 4x1 pins (because i have 9 fans and 3 seperate cathodes.)

5 out of 5 eggsBest of the Best

Pros: Quality build
Plenty of power connector
Modular design
Keeps fans running for 3 mins when PC is shut down

Cons: Price

Other Thoughts: My rig setup.
Core i7 920 - D0 stepping overclocked at 4.1ghz
Noctua 12P cooler
Enermax Revolution85+ - 850 Watt power supply
Digital Audio Card Deluxe audio card
Kingston HyperX PC16000 6GB Tripple Channel DDR3 memory
Asus P6T Deluxe V2
Adaptec 5805 SAS/SATA Raid Card with 512MB Cache and Bettery backup option
4 WD Velociraptor HLFS drives in Raid 5 Config
3 Seagate 7200.12 1TB Drives in Raid 5 Config
Ati HD4770 Video Card
2 Samsung DVDRW SH-S223Q drives with custom firmware
7 Noctua 12P fans for interior, to make it more silent than it already is.

The case really fits all of my required hardware to make my Audio mastering rig complete.
My Ableton 7/8 mastering work so nicely and PC is super silent on top of it.

5 out of 5 eggsBest ever!

Pros: Okay I haven't owned this long enough to truly test it out, but it has the best features, more features, and is by far the best looking PSU I've ever owned.

The thing that puts this PSU truly over-the-top in my opinion is the indicator light. I love the fact that all I have to do is glance at the back side of this thing and I can tell it's on and functioning correctly. That's what made me buy it even for a rig that is not ever likely to need 850W, coupled with the anandtech review.

Cons: None.

Other Thoughts: Well, okay I almost marked this down a star for this, but I don't think it is a reflection of it's overall quality and design, so I didn't. The fact is the old-style 12V 4-pin connectors (for fans and older type drives) were hard to work with because the sockets were crooked, in relation to each other. Not a big deal and not a reliability issue, just one more little thing to irritate in the assembly process that no one should have to deal with. Otherwise the cabling is outstanding.

5 out of 5 eggsWOW

Pros: the fan is big and silent, the unit has an industrial sexy look, modular cables are long enough to reach the bottom of my TT armor full tower case easily.
efficiency is the highest available today in the USA. according to my UPS's wattage meter, now my machine uses only 150w while idle, a big difference from the 300w OCZ PSU used idle in the same PC!!!! this will translate into $150-200 yearly savings on the electricity bill.

the rear led status indicator is a neat idea.

this thing comes with enough cables to power a really monstrous machine!

great service from newegg as always.

Cons: none I can think of.

Other Thoughts: a big upgrade from a 700w OCZ GX which died on me after 2 years of 24/7 operation.

physically this is the longest PSU I seen to date, make sure your case is big enough to host it. it's built like a tank.

my PC's spec. is:
GB P35-DQ6 mobo Q6600 oc'd @ 3.2 4gb ddr2 800 4-4-4-12, evga8800gts512 oc'd, 5 x seagate 7200.10/11 hdds, 16 channels in/out external sound-card
