Works well!

Pros: Compact, fits in slim Dell cases
Provides more power than my OEM PSU
Affordable
Efficient - 80 Plus Gold

Cons: Required a small amount of modification to fit in a Dell OptiPlex 7010
Doesn't include power cable
^neither of those are a big deal to me, but I wanted to pass along the info

Other Thoughts: It is technically modular as all of the cables can be unplugged from the PSU, but it would be better if every cable could plug into it individually. however if the PSU ever fails, it will be much easier to replace it with the cables being able to unplug from it.

To fit this power supply in my Dell OptiPlex 7010, I had to cut part of the plastic plug on the power supply, and I had to cut part of my case to allow the exhaust grill on this power supply to be fully exposed to the back of the PC.

Check the date on this review, and if there isn't another review on this from Derek R., then this hasn't failed me yet! Seasonic is one of the more reliable PSU manufacturers, but there seem to be a few complaints about this one on Newegg. Maybe that's just because people don't tend to write a review on this type of product unless it fails? Not sure, I guess I'll find out!

Last nine months and died, not what I would expect from a power supply.

Pros: Fits in the smaller Dell case that it was purchased for.

Cons: Purchased 10/7/2015. died 7/6/2016. Not very good life for any price and this was more expensive than most options.

Almost lasted a year

Pros: - Worked well while it lasted.
- Didn't take anything else with it when it died.
- Quiet. For low power loads, fan doesn't spin.

Cons: - Died after about 11 months.
- Not truly modular -- there are two cables that plug in to it, and I think most people will need to use both.

Other Thoughts: I didn't read the description closely enough and thought this was a typical desktop power supply -- it's actually designed for small chassis and is long and narrow. Be careful with that.

I used this for a fairly low-power home server -- it drew about 50W and I don't think it ever needed to use its cooling fan. Aside from misreading the dimensions, I was satisfied with it and would rate it 5 had it not died after less than a year.

Completely unnecessary and uncomplimentary modular design

Pros: Great efficiency and wattage for a TFX power supply.

Cons: I agree with Larry. and those who say it isn't helpful are not objective about this power supply. There is NO way to tell this will work without buying it and trying it and hoping this unconventional and proprietary and non-beneficial design will work for you. Buy at your own risk.

The modular design serves absolutely no purpose. Modular design is supposed to give different connection options. This modular design not does not provide any connection options from if it was hard wired, none whatsoever. There is either use the power supply with the modular connection or not at all. Those are the only two options: All the modular connection does is cause an unconventional design that can only restrict it's use. I agree with Larry, the power supply is noisy, has a constant buzzing sound and a modular connection that serves no purpose, provides no connection options any different than if it was hard wired.

Seriously?

Pros: Very Quiet
The fan is off if under 50% load.
Very efficient, the computer I built draws 20 watts when idle.

Cons: NOT modular (see other thoughts)
Wires are barely long enough to reach across a motherboard
Didn't come with a power cord, not that big of a deal for me, but good to know. (probably what "bulk" means)

Other Thoughts: I didn't buy this psu for the modular aspect of it, but I just had to come and write this review because the modular aspect of this psu is such a JOKE.
The wires plug into two "modular" connectors on the psu. But the funny part is there are wires coming out of both plugs that go to the 24 pin connector for the motherboard. So you Need both plugs plugged in just to power up a standard motherboard. Making the modular aspect of this psu completely and udderly redundant (pointless). I can not think of any case where this could be considered modular. I guess it would be helpful if you needed to replace the psu. They would have been better off just not making it "modular" and making it $5 cheaper. I am sorry Seasonic, I have always been a big supporter of you, but to advertise this as modular is just plane senseless.
Don't get me wrong, it is still a great psu.

Your Best Bet for TFX

Pros: 350W in TFX form factor- Enough wattage to support most entry-level GFX cards and still fit inside those annoying Dell/HP slim cases.

Cons: The wire for the 4-pin connector is 4"-6" too short. I had to run it across the top of the motherboard, which is less than optimal, but will probably be fine. A few more inches and it would have fit cleanly into the existing cable routing/management system within the case.

Tech support over the phone is... informal, to say the least. Otherwise, you're stuck with email communication, as SeaSonic is located in Taiwan.

Other Thoughts: The "modular" plugs are not what most people would consider modular, in that they are a static configuration. It is very nice, however, if you ever need to replace the PSU-- because you can replace the PSU only, and leave the wiring in place.

Also, I was momentarily confused by the second plug that goes into the PSU. There's the 24-pin connector labeled 'Power Supply Side' and then this second 20- or 16-pin connector that also must be plugged in to the PSU. Not a con, just interesting design choice.

Big PS in a small package

Pros: Powerful and silent. Seldom have I gotten the fan to spin is at any time besides POST, and this is with a Q8400S 65W Core 2 Quad :) I haven't really loaded it yet, but I'm not worried.

Cons: If I there's a con, it's the extra space taken by the (non modular) modular cable plugs. I'm using an InWin BP series tower, and this made for a tedious upgrade. I had to pull everything but the motherboard/cpu (even memory) to get it done. I also had to separate some of the 24 pin cabling to get past the cpu cooler. It's my first Mini-Itx build, but I've worked crowded builds before.

Other Thoughts: InWin BP series tower
All that 80 Plus Gold certified power :)
Intel DQ45EK Mini-ITX socket 775 motherboard
Q8400S Core 2 Quad CPU (65w)
G.SKILL 4GB (2 x 2GB) F2-8500CL5D-4GBPK
ARCTIC Alpine 11 Rev.2 CPU Cooler
1 TB Samsung F2 Spinpoint HD
ASUS 24X DVD Burner

Best psu for ITX

Pros: High efficiency = cooler temps, lower power bills. Fan doesnt spin when under certain wattage load, I think around 100-150. Never turns on in my rig unless I'm gaming.

Cons: No cons. About as long as an ITX board and tall as a low-profile graphics card... that's my tiny workstation/gaming machine the size of a book and almost completely silent during normal use (700rpm 120mm fan on CPU is the only moving part)

Other Thoughts: If you do an ITX build and silence and space are top concern, this is your best PSU option. External PSUs are the other option but the biggest one is 160 watts and you have to shop carefully to get an efficient power brick.

With this unit you get the extra wattage headroom if you need it for gaming or heavy use, and silence during normal use, all in a package not much bigger than the size of a large power brick.
