Summary: For what I paid after rebate, I'm happy with this PSU.
Pros: Voltages are good, and fairly stable: 3.3V - 3.392V 5.0V - 5.040V 12V - 11.827V (50% load) - 12.144V (idle) Modular cables are fairly easy to work with. Fit securely into the PSU without being a giant pain to add/remove. They have straight ends on the sata cables so you can connect bottom mounted SSDs (I would have preferred one straight and one L, but two straight is better than two Ls). Fan is relatively quiet and both idle and load, although idle could be better (s...
Cons: The fan is the loudest component in my case at idle. It has a slight, fluttery buzz that isn't too annoying but is audible. I was hoping for a little better. 80 Plus bronze really isn't something to brag about these days
Summary: Per research on the internet it is made by Seasonic which makes very high end power supplys. I went with a little more power than I need so I can add one graphics card at a later date. If you plan to run 2 or 3 graphics cards you will need more power.
Pros: Great price point, very quite, cool, great cosmetics. Power efficiency is quite good.
Summary: I'm an electronic tech and have designed and built power supplies for circuit boards and many devices. Instead of going into filtering and current supply, capacitors, chokes and heatsinks, I'll just say that this unit impresses me with it's 48 amps @ 12v and 87% efficiency. For most single video card systems this 620w model is plenty of power and I think you'll find that with even a GTX 780 it will work.
Pros: Modular PSU are the best! Antec's HCG Modular was the solution to many of my wiring tucking problems! Also the price could not be beat, at the time. Never had a problem with running out of power with this supply! Very quiet when on load, the fan is awesome!
Summary: -No light to tell when its on/off -Included is two 3x-molex connector cables, would've preferred an additional sata instead a molex, can't be picky however -If it wasn't on some sort of sale, I probably would've gone with a different PSU. Probably a Corsair, EVGA or XFX -Comes with two 8-pin (6+2) for graphic cards. If you need more you'd probably have to ask/buy from antec and I would doubt that they sell cables in single pieces.
Pros: -Modular -Got it on sale for 40 with rebate, which is a great price for this. -Noise isn't very loud, more of a low hum -Mesh covered wires -Voltages have been good so far
Cons: -First one that arrived was DOA. Thankfully newegg RMA process was quick and easy. -Wires are somewhat rigid and not very flexible.
Summary: The mail in rebate was the deciding factor between this PSU and another comparable PSU from another brand. With the rebate the HCG-620M was a better deal, without the rebate, I would've gone with the Corsair TX650M for a little more money. To recap, the actual product is perfectly acceptable, and if you can catch it on sale when there's a rebate being offered (and the rebate actually goes through), it's a good value for money.
Pros: It's good quality PSU, it's mostly modular, and has more than enough wattage for any rig with a single video card. The price was attractive with the rebate.
Cons: Without the rebate, the price isn't quite as compelling without the rebate factored in. I sent in the required rebate materials (UPC code, copy of the invoice, and the rebate form), I even printed out labels for the address and return address so that there would no legibility problems. 4 months passed and I received rebates from the other parts for this build (Corsair and Gigabyte respectively) but nothing from Antec. So I emailed Antec about the missing rebate, and w...
