5 Star Review   By member andrinoid - Jan 3, 2005   

Strengths: So quite the only way I can tell if my computer is on is by looking at the hard drive light.

Weakness: Absolutely none

I have an Alien Ware that I bought in the beginning of 2001. The computer has served me well all this time, but I had grown accustom the roaring fan systems. The sound of such to not only annoy me on many an occasion and cause other family members to complain. My old PSU was only a 340W and with new AGP and PCI cards added and a filling of the drive bays, that prompted me to consider upgrading the PSU. I had read on other review that this PSU was quite, but I was shocked and dumbfounded at the magnitude of the difference. If only alien were stocked all the computers with these PSU. I am so impressed that even if I don't have such a high power demands in my future computer systems as of right now I would never ever think about putting a different brand PSU in my computer. Thank you Antec.

5 Star Review   By member Rehlyimah - Apr 11, 2004   

Strengths: Lots of power to spread around, very stable power levels, small

Weakness: none, and believe me, I TRIED to find one

I'm running a system vith quite a few components reputed to be power hogs, and I'll admit that I was worried about the amount of power being used, even with a 550-watt supply. But no, no power shortages, no voltage instability, no problems whatsoever. I can't comment on noise, since I'm running five other 80mm fans, but it stays very cool without starting tornados in the room like my last couple computers/PSU, so I'm assuming it has to be quieter than most. External power feed is also a plus, use it for testing CCFLs.

3 Star Review   By member resurrection20 - Feb 17, 2004   

Strengths: Rated at 550 Watt Constant Power SATA Connectors. Special Fan Connectors. 2 90 MM fans to keep it cool. Extremely quiet. 20-pin Mainboard power input cable is shielded in mesh for better air flo

Weakness: Fan Connectors do not provide adequate power to the fans and will let your system overheat. Not enough Molex Output connectors. Mass of wires that is hard to hide and to keep out of the airflow's wa

Besides the fan connectors providing minimal power and causing my system fans to barely run and thus allowing my system to overheat, and besides the rats nest of wires that stick ouf the PSU and them being almost impossible to form into any sort of shape to allow airflow around the inside of your case, it's a damn good PSU. It's quiet, has dual 90 MM fans. Lots of features, it even has an external molex output for external devices. I got this PSU so I could have 7 IDE devices: A CD-RW, a 32X CD-ROM, a DVD-ROM, a 100MB Zip Drive, 3 HDDs, and a Radeon 9800XT which requires it's own Molex input...It's all fairly snazzy and works great so far, my system is running in tip top shape and my casefans are running faster than they ever did on my 300Watt Enermax PSU. Just make sure your fans are connected to the normal 4-wire Molex inputs and not the lame 2-wire fan inputs that are supposed to let your fans be heat-controlled, but really don't. This is a must for high-end PCs and performance enthusiasts! It's pretty cheap, too! ^_^

5 Star Review   By member JKVV - May 24, 2003   

Strengths: Lots of Power cables available.Made my AMD computer VERY quiet! Its true! Nice Online INFO FAQ (I suggest you read about it before you buy it) Very popular with PC addicts.

Weakness: NONE!!! cant say it enuff!! except for the fact that its not like the true control 550

Had to resolve INFINITE LOOP ERRORS. And didnt mind buying this one to replace the crappy 400watt psu I had (came along with the barebone system) Online forums highly suggested this. I had and ATI RADEON 9700 and a NFORCE mobo. Turns out the RADEON was a power HOG! My computer would black out when playing games. So this pretty much helped. You wont need this PSU if you dont have INFINITE loops. Another this was that this baby had soo many cables,it even had a seperate cable for just the case fans. As I read the online details turns out this is made for servers. And it made the computer very quiet. So I guess this thing is a 5 star PSU:) worth the money!

5 Star Review   By member AlexanderAkulick - Jan 26, 2003   

Strengths: This supply provides stability at each connector and is extremely quiet, excellent for gamers and any high performance system. It is also rated for continuous power at 550w and many others aren't.

I installed this power supply to resolve standby mode problems and infrequent crashes that required shutdowns and rebooting, and also after not being able to determine my exact power requirements for various PCI cards and my VGA video card as the individual manufacturer techs could not provide this information. -- WELL WORTH THE MONEY -- *note This power supply will make many computers more quiet. Antec's techs were the only people to suggest this solution and they were correct. Antec is an excellent company to deal with, offering not only great products but immediate unquestioned warranty service on products in warranty by excellent service representatives, and DETAILED PRODUCT INFORMATION at their web site www.antec-inc.com . I am a well pleased returning customer of Antec having owned several of their products in the past that continue to work flawlessly.
