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

Pros: Live on arrival, and works great. Perfect choice for general computing desktops. The 80+ power efficiency and power factor correction. Runs much cooler than the supply it replaced. Large, quiet fan moves plenty of air. Great power supply at a great price.

Cons: None.

Other Thoughts: I installed this unit in a server that runs 24x7. This newer design 80+ efficiency and power factor correction generates noticeably less heat and fan noise than the unit it replaced. I might standardize on this supply for all future builds.

Pros: Super quiet, energy effecient, you can't go wrong.

Cons: Some of the cables are quite short. Not too short that they won't make it but short enough that you may need extensions for a good fit.

Pros: Spending a bit more for a higher end - but low wattage Seasonic PSU like this reflects someone who actually knows what they are doing.
Seasonic imo consistently has the best build quality. The metal's are heavy, the fan looks sturdy and performs well and is quiet. I've never had a seasonic psu die on me. Heavy metals = durable capacitors. (yrs exp. as corporate system builder fyi)
300watts is enough for a rig that's used for basic work and office tasks.

Cons: You can't power any gaming GPU or 6-core i7 with this. (Obviously, and you also didn't spend $100+)
Visually it 'looks' the same as $20 psu's

Other Thoughts: The benefit of a good psu is peace of mind.... even if it looks the same as a cheaper psu

Pros: This is the second one of these guys I have purchased. This one has not given me any issues yet. Voltages are better than the previous one.

Cons: The last one I had purchased died after a few hours of use. This one so far has not given me any issues.

Other Thoughts: I have always had good luck with Seasonic. I think the first PSU that I bought was a fluke, all of the other PSU's are still going strong from them.

Pros: Very quiet.
Fits perfectly in an Antec VSK-4000 case.
Paired this with an AMD A4-5300 APU - no issues, plenty of power.
Cables are all plenty long for this case.

Cons: This is a relatively heavy object - psu was wrapped in bubble wrap but the sides and corners of the psu were still exposed therefore susceptible to shipping damage. Basically, it would have been nice if it was wrapped better for shipping purposes.

Other Thoughts: People that are complaining about missing power cord, etc. - This is an OEM unit, which normally implies bare bones unit (no box and no power cord and no manual).

Pros: Plenty of cable length and SATA/IDE connectors. Amazingly quiet.

Cons: There was no box, screws, AC cord, documentation, etc. You literally receive the PSU and that's all. Personally, I didn't need them but some buyers might.

Other Thoughts: I had a Seasonic micro-ATX PSU that's still going after 9 or 10 years. I hope this one holds up just as well.

Pros: Nearly silent fan. I always test new power supplies by shorting the green wire to the ground wire and because it was so quiet, I thought it was DOA. But it was working just fine and surprised how quiet it was. The plugs supplied is adequate and appropriate for a power supply in this range. After all, it's only 300W. You are not going to power a high end gaming rig with this and it was not meant to.

Cons: No power cord but I knew that. It's OEM as listed, peeeooople. No minus egg for that. The main power cord and the 4 pin CPU cord is a little short. Works well for top mounted cases but watch out for lower mounted cases. If you have a lower mounted case, look elsewhere and save yourself the headache.

Other Thoughts: Bought this to power a new build for my brother in law. He needed a fast computer for office work for his business. It's strictly an office machine with some video/youtube and netflix streaming. This is powering:

AMD A8 APU with on chip Radeon HD 7650 video
MSI FM2 board
OCZ Agility 3 SSD 60GB (OS and all apps)
WD HD (mechanical for file storage)
Samsung DVDRW

All is working well and this power supply is more than adequate for this setup. Whole system is very quite, and plenty fast. Perfect for an office environment.

Pros: Works.

I'm currently powering three 3.5" hard drives, three 120mm fans, and an AMD Athlon II x2 with this PSU. No hiccups yet, and I leave it on 24/7 as a home server. (about 4 months of near-constant uptime atm)

Cons: n/a

Pros: Quiet, uses 10 watts less than the power supply it replaced.

Cons: None for my application

Other Thoughts: I had an older 500 watt PSU in my HTPC that was overkill, and wanted something more aligned with the purpose. This thing dropped average power draw by 10 watts, and is much quieter. Not much in the system, so I can't complain about lack of connectors. Great for most basic systems that don't have enormous video cards.

Pros: CPU 4 pin power cable is 13" without the connector. Runs quiet, no problems so far.

Cons: None, it's a power supply.
