I think Antec hired the same company that does packaging for Apple to package this power supply. If what's inside the box was garbage, the packaging wouldn't matter - but this is one solid huge well built power supply.

The box - there's a black cardboard/paper sleeve. You slide that off to reveal a black box top and bottom with a yellow box in between. Take off the top and you are greeted with a black cardboard insert with a real live signed by a human being performance print out. Under that is the power supply in a double looped cardboard and foam box. Lift that box out and there's another cardboard card that covers the modular connectors. All neat, tidy, packaged with just the right amount of materials to keep this whole unit well protected.

The supply itself. This thing is so pretty, I almost want to have it on display. The black paint is beautiful. Actually I'd guess this supply would work great with the Antec Spider "enclosure". You can also feel the quality in the weight, this is a heavy PSU.

Cabling - the fundamental important cables are hard wired to the PSU. Wrapping is done with black nylon mesh where the loose ends are capped with a big plastic ring that should never come off (no wire ties, no sad crimping). Antec was smart about cable separation, so you should be able to route the wires cleanly inside your case. The built in wires are standard motherboard wires (24 pin, 4 and 8 pin); 2 PCI-e 8 pin; 3 Molex; and 3 SATA. Probably just the right number of connectors for most installs. There are 4 more modular sockets 2 for more PCI-e 8 pin connectors; and then more Molex / SATA connectors. The supply comes with additional modular cables: 2 x 3 Molex connectors; 2 x 3 SATA connectors; and 2 PCI-e connectors.

So this PSU could provide power for a ton of fans, a big old load of IDE / SATA hard drives (9 of each), and 4 video cards (or 2 that require dual PCI-e connectors). If you've read this far, you are interested in this PSU. Please do yourself a favor, and don't just take my word for the quality of this PSU; type exactly this in google and read the first link: jonnyguru antec signature 850. You will be very very happy you did that, and you will be very happy you purchased this PSU.

It fit perfectly in my Antec P182 case. And it is very quiet when running. There are fancier, flashier PSU's. Antec took the silent strong approach to this PSU.

I knew sticking with Antec would be in my best interest and once again, I'm not being let down. This PSU is whisper quiet, provides a ton of constant clean power to all of my devices (and I have a TON) and it looks nice and clean sitting in my case. All of my old gaming machines have Antec PSU's in them and they still work great. I know I will get a long life out of this new Signature 850 and from what I have seen thus far, I highly recommend it!

I have a brand new Dell Studio XPS 435- the Dell power supply could not handle the transients during a switch from house power to UPS power. Two Dell power supplies and two motherboards later, Dell could not provide any other solution - so I installed the Antec and have not had a single problem since. This is a high quality power supply that I most strongly recommend to anyone.

I've been using Antec PSU's for several years starting with the 350W to this 850W. Antec Signature Series specifically the 850W PSU is the best PSU I've owned. This PSU is extremely quite and provides the necessary power to run my computer with Nvidia 260's in SLI and the rest of my accessories with power to spare. Great PSU.

No disappointments. Very quiet and well built. Excellent workmanship from the packaging to the PSU. Highly recommended.
