SeaSonic ECO 300 300W SFX12V (v.3.1) 80 PLUS Certified Active PFC Power Supply

Pros: So quiet I can only hear a noise if I take off the case and put my ear next to the fan.

Fits SFX-compatible cases like microATX.

Cons: The basic dimensions of the PSU itself are 125mm x 100mm x 64mm, and the fan housing protrudes an additional 12.5mm from that. It slightly overlaps a corner of my motherboard, which would prevent me from plugging anything into there if that was necessary (which it isn't).

Other Thoughts: I replaced a PSU that sounded like a jet engine, with intensely heated exhaust too. The Seasonic is worlds better. Hopefully it is as reliable as people say.

Pros: Very well made and reliable power supply.

Power supply is especially well suited for legacy micro-atx cases. Connectors for a peripheral devices are more than adequate for a micro-atx build. Connectors are of perfect length for a micro-atx case.

Power supply is highly reliable.

Cons: No serious cons that would prevent me from buying this power again or recommending this power supply to friends.

The 80mm fan is audible during opertion but not loud.

Other Thoughts: I'm satisfied. My experiences are with the predecessor of this power supply. From what I can make of the specifications and pictures from then and now, this is the same unit upgraded to current SFX12V (v3.1) standards. I feel these comments are applicable.

I purchased this power supply as part of a complete rebuild of my Pastors 10-year old Dell in late 2007. This rebuild consisted of an ASUS M2A-VM 690G mobo, a 65W Athlon X2 4600+ CPU, 2 GB of Mushkin DDR2-800 memory, a Seagate ST3250310AS 250GB harddrive, Pioneer DVR-112D DVD/CD optical drive, and a floppy drive. This was powered by a Seasonic MicroATX-SS300V 300W SFX12V 3.0, the direct predecessor of this power supply. All of this was installed in the original Dell case that would only permit an SFX power supply.

This power supply has functioned in my Pastors PC for nearly 2 years without failure.

Pros: Stable power output, I sought out an 80 plus unit, and this one has done its job well! Fan is very quiet, but not silent. Temperature stays as cool as can be. SeaSonic has impressed me. Spend the extra dollars and get this quality PSU.

Cons: Fan mount may be too tall for some ITX cases. I ended up making my own case since the PSU was too close to the e8400 and was inhibiting proper ventilation.

Other Thoughts: Powering ZOTAC nForce 630i mini-itx board with e8400. Running nvidia 8400GS (at 1x PCI-e) and 3gb DDR2 @ 800. Western digital Velociraptor 300gb.

Pros: Powerful little PSU. Does what it's suppose to do.

Cons: Naw... None.

Other Thoughts: Had to purchase this PSU because the case I was using (HP Pavilion 6635) for my custom pc didn't have any. What can I say, the case is small.

Pros: High efficienty and quiet. Comes with ATX power supply bracket.

Cons: Fan is pretty quiet, but quieter.

Other Thoughts: I ended up putting it in a standard ATX case, so ATX bracket came in handy.

Pros: it is a nice and heavy unit so it has good quality components. 80 plus certified so its good for the environment and your electricity bill.

Cons: it is bigger than i thought and was no measurements that i saw when i bought it so i cannot use it.

Other Thoughts: .

Pros: Needed more power for a pci geforce 6200 256mb graphics card; (wanted 250watt and I had a ten year old 145watt psu) and this 300watt does the job. Installed unbelievably easy. 80+ is, well a plus to have. Computers draw power even when they're "off", so this SeaSonic will pay for itself eventually.

Cons: Not much quieter than the 145watt I had. Then again, the 145watt wasn't exactly loud.

Other Thoughts: On the box it's listed as being compatible with most E-Machine, HP Pavilion, and Compaq Pressario models.

Pros: Very quiet. More connectors than I need.

Cons: None

Other Thoughts: I bought this to replace a noisy proprietary psu. It fits in the case and is almost silent.

Pros: Excellent Power Supply! Very Efficient, very quiet. Cannot tell the computer is even on. The reality is the only way I get to hear any decibels is to put my ear against the power supply (nuts!).

Cons: None.

Other Thoughts: Buy it!

Pros: I bought this power supply because it was reviewed as quiet and energy efficient, and I have been happy with it. It cut the noise down to almost nothing. I also like the small form factor, which increases airflow in the case.

Cons: None.

Other Thoughts: If you are looking for a quiet, efficient power supply, this is an excellent choice.
