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.

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.

5 out of 5 eggsAmazing

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: Fantastic quality PSU - professional reviews give it very high marks for its electrical performance (e.g. voltage regulation/ripple suppression)

Build quality is very good.

As good as fully modular - only the CPU power cable and 24 pin ATX cable are hard-wired, and everyone needs those.

5 year warranty

Unbeatable price!

Cables are a good length for all but the largest cases.

550W is enough power for almost all single CPU + single GPU systems.

Cons: At its price point, none.

Other Thoughts: Absolutely amazing power supply if you're on a budget and don't plan to use multiple graphics cards. Highly recommended.

5 out of 5 eggsGreat PSU

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: -Extremely silent even when pushed to the limit.
-Feels very well made.
-Does what I needed.
-Great bang for the buck
-Modular
-Has a nice little bag to put the spare wires... which I would have preferred better wires.

Cons: -Wires are the worst I ever seen. Do yourself a favor and get your own cables if you're in a professional computing business. Units were built to satisfy a consumer marker, professionals usually have their own wires they put on any machines anyways.
-Non-modular wires are too stiff and bothersome for my operation.

Other Thoughts: I bought two and both work fine and ran 24/7 since getting out of the box. Again I would advise using professional cables if you are a serious computer user. Highly recommended, quality of PSU itself far outweighs the awful modular cables.
