Full throttle power

You could search the four corners of the earth for a stable and reliable power supply, but actually you need to look no further than Antec's TruePower Quattro! Available in 850 and 1000 Watts, Quattro is more compact than most competing power supplies of the same wattage, yet ideally suited for handling the most demanding system specs. TruePower Quattro is 80PLUS Bronze certified which means that Quattro consumes about 33% less energy than many equivalent power supplies with the same power output. Four 12V rails increase your system stability by letting you distribute your power more than ever before. Comes with four PCI-E connectors for powering one (or even two) of the newest generation of video cards. All modular cables are sleeved and labeled to give your system a clean and professional look-while the racing stripe paint job will add some extra style.

A bit large (expected)
I got this on sale for $100 so I really can't have any complaints.
I have never had any problems with this PSU and runs my computer like a charm. BTW I am running a power-hungry 6-core processor and a GTX460 OC. If this is on sale anywhere below $100 you should have good reason to buy this PSU.

Experience: 3 Years
A lot of cables, steady operation.
Had it for 3 years and no problems

Great PSU, super reliable, top notch build quality
Overall very satisfied after two months ownership. Don't hesitate to buy if you are looking for 850watts. System uptime stable for over a week. I havn't run any significant diagnostics on it but i know good build quality when i see it. Good modular design!

Modular FTW!
SATA power cables a little thick for the HAF case
This was my first modular PSU and it works great. The cables were just the right length and easy to install and position around the case. Although, they probably could cut down $5 on the price and not use such a fancy painted box.

Antec name brand, cheaper than competitors
not fully modular
This is a great bargain power supply when it's cheap (as in a little over 100 bucks). It's not the best power supply out there for this wattage, as professional reviews will tell you. However, it is still up there with the best and remains a fantastic deal when you can get it on sale. The racing stripe makes it look cool, in my opinion, because the interior of my case and components are all black. For those with other colour schemes, you may not be too crazy about the stripe.

stylish looking, stable power
some inconvenience due to my case, should be fine for others
Bought it when it was like 140 bucks or something. Overall a very good PSU. There is only one thing that I'm concern about, although it is not critical. I'm using Antec 183 and have to take out the middle HD tray to satisfy the space need of my 5970, and I have 4 HDs down at the bottom HD tray. Since I'm using 4 HDs so I need 4 SATA power which take up two module slots. I have to use molex power for the two 120mm fan on top of my case and this takes the last module slot. Now, I think I will have trouble to install a SATA powered Opt drive because the cable is not long enough to reach the HD on the bottom and opt drive on top at the same time. Although it is not a big deal since I don't use opt drives much anyway, this may be sort of inconvenient at some point. It's not critical though.

- Unless you're running tri/quad SLI this will be enough for anything under the sun
- I like the paint job
- Cheap, got it at $110 for 850W
- LOUD... at least to my ears
Okay, first of all the only negative thing I have to say about this PSU is the noise. My computer is watercooled by 6 x 120mm fans with 2 more 120mm for intake plus a silenx 80mm fan and the LOUDEST thing in my computer is this PSU. Disclaimer: My case is an Antec 300 (no sound proofing like the p182) that has been hacked to pieces so that it'll fit 3x120mm rad and a 2x120mm rad.

Still, I'm disappointed that this PSU is so loud since I bought this expecting it to be silent at idle as I'll only be drawing around 450W. I think the fan itself is not loud, but the wind turbulance is what's causing the low frequency noise. What really makes meis the fact that at idle, the air comming out of the PSU is only around 30C... cooler than it needs to be. I'd rather have the fan stop or spin at a lower RPM and have the exhaust at 40C

I used a multimeter and at idle, I found the fan to be drawing only 4.88v. It's a real shame that I built a fan controller for my 120mm fans (granted that most are low powered ~0.15A fans)and even at 12v they are quieter than the PSU fan is at 4.88v. Just for comparison, I would say the loudest fan in my computer is the antec tricool at high (30dba) followed by the PSU then followed by the yate loons at 28dba. (I always keep the antec tricools on low [25dba] which is why the the PSU is the loudest thing in my rig)

I might replace the 80mm fan with a noctura 80mm fan like this guy did here: just to get rid of the noise at idle in a month or two. I'll report back when I do.

This PSU looks pretty good and it works without any high pitched squeal. My computer is fairly old and I'm only running dual SLI so I'll probably never eveb hit 700W so I really won't be able to tell how solidly it performs at it's max. Just incase you're wondering if it'll power your system, my computer specs are as follows:

E8400 g 4.25Ghz at 1.4v/1.38 load/idle (vdroop on)
8800GTX 660/2120 SLI
780i FTW
4GB OCZ PC6400 DDR2 g 1020 5-5-5-15 2.1v
Swiftech MCP655
3x 640GB WD Blue
8x 120mm fans (some high performance, some low)
1x 80mm fan
1x Fan controller that controls all the fans ( DIY PWM that runs at 97% effiency)
And of course the Antec Quattro 850W powering the above.

Overall, I think if you're going for a silent computer, go for the Corsair TX950 that's on sale now for $140. The high overhead means that the PSU won't run it's fan at high RPM. The fact that it has a larger fan helps too. If you're going for the higher OC and less ripple and are running air cooled or stock GPU fans then this PSU would be better due to the better ripple characteristics below 800W than the TX950.

The look,part modular and lots of power.
No bottom side cooling fan
Picked this up for 119.99 in December. Lots of power more than i need but couldn't resist. I recommend this to any one for any build.

stable, strong, silent, good looking
not really modular
Very good PSU, you can trust antec. It does not have a fan on top, which is good with case like antec 300 where the PSU is on the bottom, as if a fan was present on top of the psu with those cases, hot air would be pushed toward the CPU.

Experience: 2 Years
One of the best PSU I've owned. Very solidly build and tons of long cables. Power excellent and stable. Very quiet for an 850!
PSU is huge, and cables are big and long. In small or medium case it might not be useable.
For 2 years of usage it's a workhouse that has no signs of stopping. Thanks Antec another top of the line product I've bought from your brand name.

Comment: The Antec True Power Quattro 850 is a top end performer that will meet the needs of all but the most power hungry enthusiast machines. Voltages during our tests stayed within 3% over all loads and the unit is good looking to boot. The modular design is a boon to cable/wire management and Antec has

Comment: Jonny gave it 9.5/10 and the recommendation sticky. Barely no ripples and this should make other high end PSU run for their money.
