Pros: If you are looking for a computer power supply unit (PSU)that is capable of sustaining your computer for several years then choose a SeaSonic. I choose these for my personal build, my family members, and recommend them to anyone that want a computer built for their home. Desktop that are built to last will have a SeaSonic PSU pushing the power through them...great PSU for the price.

Cons: None so far.

Overall Review: I recommend these power supply units to anyone that build their own computer or has one built.

Pros: 80 Plus Bronze Low Wattage Great Brand Runs cool & quiet Intel i3 System Idle: 40 watts Load: 70 watts

Cons: Just in case people may not know, it should state somewhere that as an OEM PSU it does not come with a power cord. This wasn't issue for me as I have plenty but others may not and it would be best if they knew ahead of their purchase.

Overall Review: As others have noted the cable lengths are a little on the short side, this mainly applies to bottom mounted PSU cases, if your case uses a top mount for the PSU everything should reach just fine.

Pros: Significant power savings over typical/older power supplies. Using a Kill A Watt device, I measured my system at ~147W. I was using a Sparkle PSU that's about two years old. After switching to the SS-300ET, the power dropped to ~110W. My system is on 24/7, so I figure the 37W savings will net about $35-$40 a year in power cost reduction. That'll just about pay back the cost (ROI) in one year. Highly recommended.

Cons: Caps are "Su'scon" brand. Websites and discussions of the dreaded "Capacitor Plague" (early capacitor failures common in motherboards and power supplies) indicate this brand has had problems in the past. Only time will tell if the SS-300ET will suffer from capacitor failures too. I would have preferred to find top-quality capacitors inside.

Overall Review: High quality ADDA 120mm ball-bearing fan (AD1212MB-A71GL) is whisper quiet and I'd expect it to have a very long and reliable lifespan. This PSU is only 300W, but this is sufficient for many systems, and power efficiency is often better using a properly sized PSU. If you wonder how much power your system actually uses, get a "Kill A Watt" device (available on NewEgg and surprisingly inexpensive, in my opinion) and find out.

Pros: I just finished putting these in 35 systems for a computer lab. I didn't have a single problem with any of these power supplies.

Cons: None.

Pros: I bought 20 of these units over the last few months. Every single one powered right up and worked flawlessly. None have had any problems at all. They're whisper quiet and save power. Even if a power supply is still working, I think it's worth upgrading to one of these for the power savings and quiet operation.

Cons: None.

Overall Review: Power consumption is significantly lower on every system when these power supplies are used to replace the standard one. For me, replacing a typical 300W power supply nets a 20-30W reduction. When replacing an oversize power supply (450W/550W), I've seen 35-40W reduction, and these power supplies have no problem running the system.

Pros: SeaSonic are still the best. Have always used them and they are always silent running, steady and reliable. Able to withstand power outages and surges without a surge protector. And are as energy efficient as any psu on the market. (tried fsp and these are more efficient)

Cons: None

Overall Review: My old 380 watt SeaSonic used to power just about any system I put it in and it is going on 7 years old. It is still powering a system now. Tried this little 300 watt...it was not quite enough for the following htpc system: 890GX chipset, 95 watt quad core, 8 gigs ram, 2T WD "green" drive, 80G SSD, 5450 graphics card, HT omega striker sound card. System would have random shutdowns. Changed to an older 550watt Mushkin modular supply and system runs perfect. The 300watt is now in this system: 780G chipset, 65 watt dual core, 2G ram, 160G SATA drive (onboard graphics and sound). Runs perfect and idles under 40 watts.

Pros: I have been getting this power supply from another site... one that has auctions, and they are like-new, perhaps new system pulls, but sold as refurbished. I have bought 8 of them, and they have all been rock solid and QUIET. I have replaced several OEM (junk) Dell, HP, etc. PSU's with this one, and they have all worked great. And several people have commented about how much quieter their PCs are.

Cons: Don't buy this PSU for an ATX case. Don't buy this PSU if you want an 8-pin CPU plug. Don't buy this PSU to power a 6-pin video card.

Overall Review: For a basic home or office PC in an mATX case, and at the right price, this PSU is great.

Pros: Quiet

Cons: Doesn't have 8-pin CPU power that most motherboards have now days. My mobo still operates with just the 4-pin connection so not a big deal in the end.

Overall Review: Wish newegg would list all the power connectors that power supplies have.
