3 out of 5 eggsNoisy, Hot and bad modular design

Pros: Plenty of juice for low profile systems. That's all I can say good about it, which allowed me to put a more powerful video card in my HTPC.

Cons: I've had it in a HTPC for almost a year now and I just don't like that modular connection. I am using an InWin HTPC case and there is a fan holder bracket on the side of the case that is right against the inside end of the power supply. For me to use this power supply, it requires me to remove that and prevent me from putting a fan there. So here I am, running a higher watt power supply and a hotter running video card (vs the onboard video especially) and decreased ability to keep it cool because of the modular design. I regularly felt the PC case and it was warm, sometimes hot. I took off the cover and felt the power supply and that was pretty warm, in addition to a warmer running video card...NOT good. I decided that I just can't use this power supply since it runs warm and blocks the use of an additional fan for cooling. I want my HTPC to last a while and this eventually will shorten it's life span I fear due to the heat.

Other Thoughts: See Cons

Manufacturer Response:

Hi Actonicnet.com H.
Thank you for your review. Please note, the TGM power supply was designed to meet most HTPC cases on the market today but since not all HTPC cases are of the same design, there can be slight compatiblity issues.
As for the temperature, the PSU may feel warm to the touch when in operation, it is always important that there is good case cooling & air circulation to any system to run properly, be it HTPC or ATX.
Thank you.

5 out of 5 eggsSeriously?

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.

5 out of 5 eggsYour 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.

5 out of 5 eggsBig 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

5 out of 5 eggsBest 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.

5 out of 5 eggsSilent, Saves Power

Pros: Silent, fan stops when under 50% of load
80+ Gold saves Power

Cons: None

Other Thoughts: I purchased this TFX Power supply to replace an IN-WIN PS that I felt was too noisy for my home server mini-itx chassis. The server is on 7x24 and is near my home theatre, so I had two simple requirements: high power efficiency and low noise.

I am profoundly impressed with how this PS meets these requirements. Idle power draw has dropped from 57 watts to 40, and my server is now completely silent, even under load.
