SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC Power Supply

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: 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.

Pros: PSU. Very quiet as long as you keep the power draw under 150w at the plug. As cheap as you can get for a bronze plus.

Cons: Cables are on the short side; but I was warned when I read the other reviews, so no surprise here.

Overall Review: Fits the needs for probably 85% of the worlds computers!!!

Pros: Definitely seems to be efficient. I have an I5-750 with G210 passively-cooled video card idling at about 39 watts. The 120mm fan moves a decent amount of air but stays very quiet.

Cons: None so far.

Overall Review: It should be noted that I haven't installed a hard drive yet (using an Intel X25-M SSD as the boot drive.) However, my WD 1TB Green should only bring idle power up to about 43W. And most of the time it'll be ramped down, keeping my idle at about 40W.

Pros: quiet, cool, high quality materials and components plus very generous wire lengths.

Cons: absolutely none

Overall Review: Many owners have complained about the shortness of the CPU connecting wires. The four SS-300ET units that I received have the LONGEST wires of that sort I've ever seen: 14 inches!!! The SATA connecting wires were also the longest I've ever seen: 21 inches!!! This is my first experience with a SeaSonic product. I will purchase only SeaSonic PSU's in the future.
