Pros: It did what it was supposed to do for 1 year. It was on sale when I purchased it.

Cons: Worked for a little more than 1 year. Submitted for an RMA with Antec. I can see my case on their web site, but they do not appear to be in a hurry to assist. I am without the service of my computer while they are taking their time.

Overall Review: I am disappointed in Antec's customer service. I went with them because I thought they would offer better support than companies offering power supplies for less. I realize that power supplies can go bad, but I expected to be contacted with an RMA much sooner than this.

Pros: Great design with the modular cabling. Fantastic power regulation. Quiet fan operation. Extremely efficient and reliable.

Cons: None so far.

Overall Review: I was having some thermal issues in my case and it was effecting my power supply. I upgraded the case (Antec 300) and the PSU. What a difference!! I was running around 40c core temp, not good. After the case and PSU upgrade I am steady at 27c all day long. Awesome!

Pros: Semi-(hybrid)-modular 5 year warranty Quality (it's a rebranded Seasonic) Price Quiet and stable Looks good, too

Cons: Not really any real cons as such

Overall Review: Some reviewers have mentioned the use of so many hard wired cables, but one must keep in mind the fact that everybody needs a certain minimum number of cables/connectors. Making everything modular except for the 24 pin motherboard connector would raise the price of this unit by a significant percentage. Keep in mind that "you get what you pay for", and this PSU is a good compromise for features, quality and price. The unit I received was painted a matte black, and when installed in my Antec 902 case, just the embossed Antec logo shows. It's not fancy with flashy colors, but who cares? Running two HD 5830 in Crossfire, the 12V outputs all stayed within 1% of nominal , which is really very good, and exhaust temperatures never rose above 50C, with the fan running quietly even though at max. Of course, my hearing isn't what it was 30 years ago, but noise levels were quite acceptable to me. Overall this is a quality PSU, and at the price I paid from Newegg ($80) it was a nobrainer.

Pros: *Exceptionally high quality power supply. Everything about it is well-built, sturdy, and heavy which for power supplies is a good thing. Light weight ones usually are made of inferior quality parts so don't let those light weight ones take the rest of your PC out with it. Even the cables are high quality and are properly sheathed, which means they won't unbraid on you over time. Also the smallest details like the connectors stand out. They pop in easily and out without pulling your peripheral connectors with it. You should with cheaper SATA power cables when they latch on so tight that when you remove it, it pulls the power connector with it. Not so with these ones. Never have to worry about that. *Plus it comes with the perfect amount of permanent connectors that's enough to power a motherboard (comes with both a 4 and 6 pin), video card using two PCI power connectors, two SATA DVD drives, and two WD Caviar Black Hard Drives and if you need more, can easily attach more.

Cons: *It's pricey for a 650W, but the quality justifies the price. *The included modular cables are kind of short so might have problems reaching in full towers. No other Cons to speak of atm.

Overall Review: When purchsing power supplies and receiving it, the first thing you want to do is grab a high power flash light and shine it in through the vent holes. NO i'm not talking about opening it, just talking about shinning it through so you can see the insides. If all the capacitors have a visible or non-visible thermal paste/glue under them, great that means it's a high quality power supply and the company takes great pride and QC into it. But if you see white or brown goup (thermal paste) dripped all over the capacitors, then you know it's cheap and the company doesn't take great pride in it. Never encountered one of those yet with Antec, but seem to find those ones all the time with R0$ewil! and 0CZ.

Pros: Quiet, modular, works

Cons: none, see below if you have issues with coil whine or high-pitched noises during operation

Overall Review: If you are running this PSU and noting a high-pitched noise emitting from the unit, disable EIST and C-State in your BIOS and see if the issue persists before RMAing the unit. It fixed the noise problems in my case (found the information via Corsair).

Pros: The hybrid modular cable design is nice. The main ATX power cable and a few SATA power cables are permanently connected and then you are provided with plenty of other cables that can be plugged in as needed. It works quite well. The fan in it is nice and quiet too.

Cons: None

Overall Review: So far it is working great, I have a C2D E8400, 4GB DDR2 1066, a P45 chipset mobo, 5 hard drives and an optical drive running on this without any problems.

Pros: Was less than a hundred bucks when bought. Running for over 6 years without one issue. Modular makes for simpler cable management, though there are some that still need to be tucked away.

Cons: Cables a bit difficult to manage due to thickness or stiffness of sheathing. Some aren't quite long enough to reach the top of my case easily. Some of the threaded mounting holes had some manufacturing shards left inside that I had to deal with.

Overall Review: Still running its (nearly) original hardware, save for a couple HDDs, an SSD, and upgraded GPU. I was planning to swap this PSU for something new when I upgrade, but my Sandy Bridge i5 2500k still running strong at 4.52 on air. Not worth upgrading yet. i5 6500 at stock wins some and loses some against the 2500k in benchmarks. Single core is way better on the SB but only slightly worse on multi-core. Of course, this item isn't a processor.

Pros: Delivers stable, tightly regulated power Well balanced voltage regulation and efficiency Excellent Ripple suppression, especially on the 12V output. Silent at low power loads 5 year warranty Almost nothing can compete with this unit at it's current price as of the date of this review.

Cons: Antec sacrificed a little noise to keep temperatures only slightly above ambient when under full load (This can actually be a Pro now that I think about it) Antec Goofed on the ATX12V V2.3 / EPS12V V2.91 design, both connectors are hardwired to the unit. Your system will only need one or the other so this should have been a modular option.

Overall Review: The cons are not a huge deal so this unit gets a perfect rating from me due it's terrific performance for the price making it the best value for your money.
