Pros: I have a bunch of these on production systems and a couple on the shelves as backup. These systems have been using these supplies for over 14 months. They seem professionally made, unlike most supplies nowadays. The fans are silent and the enclosures are solid. The cables are long enough to reach in tall cases.

Cons: I paid 3x the current price over a year ago!! newegg shouldn't sell these so cheap or people will think they *are* cheap. For a 550W, I was surprised they didn't have more drive connectors or even an extra separate circuit, but it still easily supports 10+ drives in a dual-core system under load.

Overall Review: I don't understand all the bad reviews: Power supplies won't fry _good_ motherboards (overcurrent/overvoltage protection circuitry). If you're blowing components, you need to look for a better board manufacturer (e.g. Asus). All power supplies have slightly unsteady voltage rails (it's within the spec), which is why they have capacitors on the motherboards. Also under 10% tolerance on voltage is within the ATX spec. I've built my own switching power supplies and I'm amazed at the acceptable ranges for ATX power. None of my supplies seem to have any problems and I use them in beefy systems, where other 500W supplies have failed.

Pros: Good power for the price. 24-pin connector. Dual fans to keep things cool.

Cons: My switch on the back of the PS started to melt after only 1 month of use(loose connection). I replaced the switch and now it works fine. Oh and 550watts is misleading, since its peak and not cont.(400watts)

Overall Review: Its ok for the price, but keep in mind if you really need 550watts pick another PS.

Pros: It has a nice black finish. Good airflow.

Cons: It only has one Sata and no PCI-E. It's actually (according to the sticker on the side of the PSU) a 400watt power supply with a maximum output of 550watts. So don't buy this unless you only need 400watts or less. It is LOUD. I can't stand it. My Antec 1200 case with 7 fans makes half as much noise as this power supply!

Overall Review: I got it free, never would have bought it otherwise. I'll update this review when it burns my house down or something :)

Pros: It was a good price for what it was.

Cons: After calculating how much power I was drawing, I should have been under 400 watts. That's rounding up generously with my numbers. I played Jericho for about 2 hours and my box shut down. When I opened up the power supply, since that's where the smell was coming from, one of the inductors had melted. It was a great product until I needed it to live up to it's specs.

Overall Review: on the side it actually says that it's a 400 watt power supply with a 550 max. I don't think it can withstand much at a full load.

Pros: Works fine for my Athlon 64 X2 4200+

Cons: Isn't really 550w, I believe it's 400w.

Overall Review: Works great with my comp, and so far has been stable: ASRock 939Dual-SATA2 MB AMD Athlon 64 X2 4200+ 2 x 512mb Corsair PC3200 RAM LeadTek Geforce 6600GT TDH Coolermaster C5 Centurion

Pros: -Hasn't failed yet -Did it's job of providing power -Doesn't run on gasoline(although it sounds like it does)

Cons: -LOUD -LOUD -VERY LOUD

Overall Review: This thing started making noise around the 3 month mark of owning it. 2 years later, it's still making lots of noise. Save your pennies, get a better power supply.

Pros: Cheap

Cons: This thing is LOUD!!! Building two systems for a client, and when I fired it up, I thought I was at the airport! Ended up sending them back, so got stuck with return postage as well as restocking fees. If you're going to be in an environment with loud, ambient noise, these would be OK. At home or in an office setting - very few people would be happy with these.

Pros: Cheap, worked at first.

Cons: After 2 1/2 months it killed my Video card and a Hard drive before killing itself. Do yourself a favor and spend another $10 dollars and buy something decent.
