4 out of 5 eggsIf youre wanting to get this for the Silverstone fortress case -Keep reading

Pros: Seemingly well reviewed, works as expected for a powersupply...

Cons: If youre wanting to use this for the Silverstone Fortress cas (http://www.newegg.com/Product/Product.aspx?Item=N82E16811163197) and you have the expectation that you can use a 3.5" drive, or an optical drive -This is NOT your powersupply, since that case only works (with those perph's with a PS thats 100mm long or shorter)

I wouldent say that this is a seasonic problem, since any reference I could find alludes to SFX powersupplies all having the same dimensions...

2 out of 5 eggsI dunno...

Pros: It works, mostly.

Cons: I moved my system from an ATX case with a 400w PSU to a microATX case with this Seasonc 350w PSU. Before, I could put the PC to sleep and it would resume with no problem. Now, when I resume, my second hard drive doesn't wake up. The PC resumes fine, but the sound of a device uninstalling comes a few seconds after resume, and no 2nd drive. I have to shut down/restart. I docked 2 eggs for this.

Also, this has 2 SATA power plugs, 4 molex plugs and 2 floppy power plugs. WTH. Another egg docked.

Other Thoughts: This is my first seasonic PSU and I expected top notch stuff given their reputation. Not sure what to make of this.

Like others mentioned, the fan is a tad loud as well, and hardly even pushes much air for the noise it's making. I didn't dock any eggs for this, though maybe I should have.

1 out of 5 eggsTHIS IS USED

Pros: It works?

Cons: This PSU was shipped, wrapped in bubble wrap only, even with a sticky note from some other company attached to it.

1 out of 5 eggsTHIS IS USED

Pros: It worked, but not sure how long since it was USED.

Cons: Next day air took 4 days because of "processing."

I was shipped this PSU, in wrapped in bubble wrap, it even had a post-it note attached to the side of the unit with a bunch of numbers from another company.

Other Thoughts: This is unbelieveable, and marks my last purchase from Newegg, ever.

5 out of 5 eggsit fit's... sort of

Pros: Not able to actually mount but it slipped into my Dell optiplex desktop case no problem. Got it to give me a little more power when I upgraded my vidcard... does exactly what I want it to do.

Cons: it's only 350w, would have liked a little more power but it's a good steady 350 so I'm happy.

Other Thoughts: Have seen so many other Power supplies of the microatx/sfx form factor that are so junky and it's hard to find a decent brand in this form factor.

4 out of 5 eggsNewegg - Please update fan size.

Pros: Works fine powering my HTPC, which includes an AMD 6870. There aren't any PCIe connectors, so be sure to have adapters.

Cons: Newegg, please tell me how an 80mm fan can fit in a 63.5mm tall case? This is a 60mm fan, not 80mm. The fan is also very noisy and many enthusiasts would likely want to replace it.

Other Thoughts: Silverstone has some new, more expensive power supplies that weren't available when I built my HTPC. I'd probably lean towards one of them due to the cables not being modular and the loud fan.

4 out of 5 eggsSS-350SFE

Pros: Solid, good quality PSU. Small footprint, bought this to take up less space in ITX case (better airflow). Does just that!

Cons: You may need an SFX/ATX adapter. There are not lots of SATA cables. This was not a problem for my situation.

Be warned: if this is for a media server / HTPC, that needs to be silent, I think you will be disappointed! The fan is incredibly loud, my personal rating would be 2/5 eggs with the stock fan. I had no choice but to swap it, whether it affects the warranty or not. Get one of these from Newegg: Item# N82E16835191003. Run it out to a header, so you can control the speed. The difference is NIGHT and DAY. Highly recommended...

Other Thoughts: It's a very nice power supply, with a terrible fan. Solid 4/5 eggs with a fan swap, it's simple to do.

3 out of 5 eggsToo loud, would not buy again

Pros: Very good levels & regulation, 80+ efficiency, SATA power separate from IDE power, computer controlled fan RPM.

Cons: Cables at critical length, no spare length. Small (~60mm) fan is very loud. When idle, can hear fan from 5m away

Other Thoughts: Having owned other SeaSonic supplies, I expect premium quality to go with their price, but not on this one. Otherwise a quality supply, but fan noise makes it unusable, even for a desktop, forget HTPC. Maybe I got a bad one, but when it idles at 1900 RPM, I can't imagine it being quiet. After two weeks, I swapped it out for the no-name that came with the case.

4 out of 5 eggstoo short

Pros: It's a power supply, what can you say?

Cons: The cables were too short. If you are making a compact system, this might be the choice for you.

Other Thoughts: Keep in mind that peoples' opinions, who were insulted by newegg's uncriticizable guidelines, are not represented in this venue.

4 out of 5 eggsgood for the price

Pros: good Powerful 350W SFX PSU
very Quiet fan
works flawlessly

Cons: cables are too short. limits your cable managment options.
24 pin is aobut 13" long barely long enough. if I used a ITX MB where the connector is on the far side of the MB (as most

are) this wouldn't reach in most cases.
4 Pin CPU is about 11" long.
no PCIe

Other Thoughts: I put this in the a APEX MJ16 uAXT case.
Seasonic shoudld update the connectors used on the PSU:
Should put a PCIe 6pin connector
should swap a 3 x 4 pin molex string for a 2 or 3 SATA
the 4 pin 12v CPU should be a 8/4 pin connector and should be about 6" longer

MSI H61 E35 uATX MB
Core i3 2120 CPU
2x2GB G.Skill PC 1333 ram
120GB Phoneix Pro SSD
500GB WD Green HDD
Sapphire HD 6850 GPU
Lite-On DVD R/W
APEX MJ-16 w/ a SeaSonic SS-350SFE 350W SFX

I own the Silverstone ST45SF 450W N82E16817256063 also, and it is a MUCH better PSU, but $40 more :-(
