5 out of 5 eggsVery quiet!

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I don't hear this thing while it is working. I have this installed fan side down and it works so well. It is modular so I only use the cables I need. It came with all the things needed to get me up and running. It has a 5-year warranty, which tells you how confident they are about their product.

Cons: None.

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: • 80+ gold
• unbeatable for the price and quality
• silent fan operations
• semi modular cables, i like the flat modular cables
• 550w is plenty for my needs
• Addtional Velcros, sticker, zip ties. awesome goodies!

Cons: • 8 pin cpu connector is a little short for my corsair 2300t case running it to the top cut out. I did manage to plug it in but feels tight.
• 24 pin feels very stiff

Other Thoughts: I purchased this for my first build. The cable management was a breeze.

4 out of 5 eggs

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Works great and has had only one problem (see cons). I love the modular design. Very quiet and stable.

Cons: I have had two of these in different machines. Both had this exact same problem. When you screw in the four mounting screws all the way in, the fan stays at full speed for some reason, and is extremely loud. When you back out one of the screws just a bit (a certain one), the fan goes into normal operation. I've just kept one of the screws backed out for over a year now, and it works fine, but an odd problem indeed.

Other Thoughts: Other than the problem above, this is a great power supply for the money.

1 out of 5 eggsDead Afer 1 Year

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Good while it lasted.

Cons: This PSU died after 1 year, to the date.

I give 1 egg out of 5, since warranty was 5 years, but it only lasted 1 year. Since it only lasted 1 year, I'm very suspicious about this 5 year warranty thing now. This is obviously not a 5-year PSU. I can't help to think something is amist here.

Other Thoughts: I don't plan to RMA it. Costs too much money to ship. A waste of time too.

Manufacturer Response:

Hi, I am very sorry for the inconvenience this issue has caused. Please note, it is possible, from time to time, than an item will fail within the warranty period and that is why our 5 year warranty time is here to support you. Please contact seasonicusa.com and please start the RMA process. The cost for freight within the US should be low enough to make this effort worthwhile. If you have any quesitons or concerns, please contact me at newegg@seasonicus.com Thank You.

5 out of 5 eggsBought this due to reviews and quality

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I have a kid on the way and wanted to upgrade my computer while I still have the cash, plus the fact that my old PSU was hitting close to the MBTF of 5 years. I bought this due to it's excellent reviews and the renowned quality of SeaSonic PSUs.

Cons: Nothing so far.

Other Thoughts: I had bought SeaSonic for my mom's computer that I had built and it works great for her. I think she has had it for at least 3 years or more.

1 out of 5 eggsHorrible...

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Modular.

Cons: Expensive, unreliable, faulty.
I have received this PSU today and it would not run my PC for nothing, just shut down after second of having my computer on. Bad product, bad experience, never buying Seasonic ever again.

Manufacturer Response:

Hi Maksym, Sorry to read of your experience. I kindly ask for you to check to make sure all connectors are plugged in properly, possible a loose connector will cause the PSU not to boot up. If the unit is a DOA, please contact NewEgg or Sea Sonic USA RMA as soon as possbile to resolve the issue. If you have any questions or concerns, please contact us at newegg@seasonicus.com Thank you.

4 out of 5 eggsAlmost Perfect

This review is from: SeaSonic G Series SSR-550RM 550W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great psu! It is able to run my mini itx build (Gtx 780, i7 4790k) perfectly.

Cons: I had to take one egg off, because they shipped me a psu with a bad cord. It wasn't a big deal because I had a spare, but still an annoyance.
