The Antec NeoPower 550 offers super quiet operation and high - up to 85% - efficiency thanks to Active PFC (power form correction). This efficiency factor, along with Antec's innovative "straight-through" airflow path allows the fan to run slower – and quieter – as it exhausts heat from the power supply. As a result, you'll save energy – and money – on your power bills each month. The power supply is backwards compatible with all ATX 12V systems while supporting ATX12V v2.2 and EPS12V systems.
With 550 watts of power at your command, dedicated power circuitry delivers a more reliable – and safer – output to your system's components with voltage feedback circuitry and tighter regulation for improved system stability. Maximum, stable power to your CPU is delivered via three +12V output circuits independently of the other components and dedicated power connector supplies energy to any PCI Express graphics card.
The NeoPower 550 is certified Nvidia SLI-ready. In order to reduce cable clutter, the advanced cable management system lets you use only the cables you need to power your system. All of this is backed by Antec's AQ5 5-year warranty.

The skinny on Antec and Asus
- Pros: Knowledgeable tech support that answers the phone in person and speaks great English, nice dark gray finish, quiet, ATX v2.2, handles 7900GTs in SLI, dark cable sleeves give case a less cluttered look, modular connections mean you can eliminate some cable clutter.
- Cons: might not support some power-hungry DirectX 10-based SLI systems in the future.
- Other Thoughts: Antec support is PERFECT. They knew all about the Asus/Antec issue, and had options for resolution, even though the root cause is not with Antec's hardware. According to Antec support:
There is a timing incompatibility between certain Asus motherboards (A8N and one other series I can't remember) and all ATX v2.2 compliant power supplies (not just Antec). You can solve the problem by updating your BIOS (as of 7/27/06, you have to use a beta). All of the newest supplies from Antec (serials beginning with S06 or higher) have been pre-modified to be Asus-tolerant, and won't need to be RMAed. Again, this is Asus' problem, not Antec's.
The symptoms of the Asus incompatibility are very strict. Symptom 1: The computer won't boot, period. 2: The computer will randomly power off from Windows. There's no association with a particular activity in Windows. If it powers down only when you run certain applications (such as 3D games), then the problem is unrelated to this incompatibilit
Excellent is the word!
- Pros: 1. Modular connectors. Contrary to what "some experts" believe the amperage loss due to modular connectors is of the order of few micro amps. They definitely give a clean and organised look to the system.
2. 3 rails each at 18A for more balance and stability.
3. Tight voltage regulations on all rails. In my tests, it never went off by more than 1-2%.
4. SLI ready. Plenty of amps on 12V for a high end SLI system.
- Cons: No cons with this PSU. Although people like to point out low amps on 3 and 5V lines, I don't think that's a fault, because atx2.2 compliant mobo should use more of 12V rails. Those amps on 3&5V are more than enough.
- Other Thoughts: ASUS messed up and then corrected the issues they had with this unit. NOTE that I have abit an8-sli, and didn't have any problems. Quite contrary to what others have said here, this PSU works with all but Asus mobos.
One last thing I wanna point out that people tend to overbuy their PSUs based upon tonnes of internet posts about stability issues because of lower wattage PSUs. e.g. my system at top load consumes 225watts, with 4 harddrves, 3800X2, 6600GT, 2 dvd-roms. I needed at most 350watts. So, buy smartly. Read a lot. Don't listen to 'buy 600 watts expensive PSU for your high end SLI system'. Mostly look for amperage on 12V rail (on the spec sheet), and how tightly the voltages are regulated (internet reviews). At least combined 25amps on 12V and less than 3% fluctuation on voltages.

works good
- Pros: modular is nice it makes my case look nice and clean inside. more than enough power my basic gaming system
- Cons: none
- Other Thoughts: purchased as a combo deal with my antec 300 i was buying and after the savings this cost me around $25 and had free shipping :) yippee! new egg is the BEST!
Sloooooooow delivery
- Pros: It is my second one and it is very quiet, got it on sale for 60$
will buy Antec in the future
- Cons: Not really a cons for Antec...but
never take Newegg's free shipping, it's slooooooooow
- Other Thoughts: Need to upgrade PSU to handle my 8800GT
Whatta Deal!
- Pros: I got this for 59.99 with free shipping - Modular, XF Ready, solid 550W... score!
- Cons: price back up to 69.99... too bad for you!
- Other Thoughts: Cornerstone of my major overhaul... got power to spare!
