If you're looking for a power supply to feed your hungry system, look no further. The new HX850 PSU from Corsair puts out an impressive 850 watts of power and supports the latest ATX12V v2.3 standards as well as EPS12V 2.91 standards. The unit is 80 PLUS SILVER certified and has a 99% Active Power Factor Correction to ensure maximum efficiency.
The cables are extra long, to work in the largest tower. They are fully sleeved for easy routing and bundling. There are six 8-pin PCIe power connectors so you can build up a CrossFire or SLI system using today’s high end video cards. There are also 12 SATA and 12 Molex connectors so you can connect multiple drives and peripherals.
Keeping it all cool is a temperature-controlled 140mm fan. Air is vented through the hexagon mesh back panel. The universal input accepts voltages from 90V to 264V so you no longer have to worry if the switch was in the right position.

You get what you pay for.
- Pros: I purchased this PS based on [H]ardOCP's review and have been very impressed with it. I suggest looking their review (google HardOCP HX850W) and reading it, along with their power supply testing methodology article.
With that out of the way: Corsair's modular cabling system is one of the best that I've dealt with, the flat black cables look good and are easy to route out of the way. The PS is quiet and it runs very cool at moderate loads, and by all indications this thing has some of the tightest voltage regulation and lowest ripple values of any PS in this wattage range. And like most (all?) Corsair PSes, the OEM is Seasonic, which is one of the most highly regarded computer PS manufacturers. There are a few good ~850w units on the market right now, this is one of the-if not THE-best.
Running a Pentium D 820, an Adaptec 31605 16 port RAID card, 8 Hitachi E7K.1000 1TBs in RAID 6 & 2 160GB WDs in RAID 1; peak power draw is about 450w @ the wall without any complaints from the PS.
- Cons: Nothing.
- Other Thoughts: Consider this:
1. It's legal for manufacturers to take a 250w ps and sell it as a 500 watt unit-even though it'll only do 500w for 2 seconds, inside a freezer, while violating ATX specs for ripple & voltages. This is why you can find "650w" pses for 20 bucks.
2. Ripple control is almost as important as power output. Ripple is small quantities of AC electricity that make it to the DC outputs on the power supply; for instance, your multimeter might show the 12v rail being at 12.02v, but ripple will cause it to fluctuate between say, 12.019 and 12.026v hundreds of times a second-too fast to detect without an oscilloscope. ALL modern PC PSes have some ripple, just due to their design; the key is to get one that keeps it as low as possible-too much can damage everything in your system. How do you avoid that? Buy reputable brands and read reviews that are done properly-with load testers and oscilloscopes-not by putting them in PCs and checking voltages with multimeters.
Corsair 850HX
- Pros: One very solid PSU!! Running my i7 920, one HD, 2 optical drives, 5 fans and 2 EVGA GTX 260's in sli. It might be a bit more than I need but I would rather have too much wattage than too little.
- Cons: No witty comment here. :)
- Other Thoughts: If you are looking for a PSU for you sli setup check Corsairs lineup. They will not let you down.

A Solid buy.
- Pros: Modular, powerful, and connections for just about anything you could throw at it. Plenty of plugs for everything, but slim connectors/cabling for most for easy stowing of the cables you do use.
- Cons: The non-modular cabling includes the 20+4 and the 4+4 cables as you might expect, but instead of all 6 PCI-E cables being modular, 2 of them are built in. I'll be using 4 rails eventually, but I only need one right now and it's kind of a hassle.
- Other Thoughts: PSU's are so important, it doesn't make sense to skimp. This is a solid buy and it's worth an extra few dollars to do it right. If you're the kind of person that would ever consider tri-sli, or you're just not sure what you need to use, this has everything you might need.
Excellent
- Pros: Plenty of solid power. It's awesome that the auxilliary cables (not the main or PCI-E cables) are not hard-wired to the P/S. You only need to install those cables that you actually need.
- Cons: None so far.
Ridiculous
- Pros: HUUUUUUUUUGE power! Runs flawlessly, powering a Phenom II quad core, a pair of Gigabyte 5870's, 2 hard drives and a dvd drive, and 5 fans. Doesn't miss a beat.
- Cons: Modular design is a tad useless, as I am using nearly all of the cables anyhow. Cables would be more suited to a server size case, they are absolutely packed in my Antec 900 case.
- Other Thoughts: Really a nice unit, but docked one egg for the huge cables.
