This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: fancy packaging
lots of cables and some nice velcro straps included
you get a fancy velvet bag
quiet fan

Cons: none

Other Thoughts: has been giving my fancy system all the power it needs and doing so stable. ended up with a lot of extra cables, the velvet bag was unnecessary but a nice touch

2 out of 5 eggsBuy something else!!!

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great looking and over-the top packaging!

Cons: I have had to RMA 2 of these units in two years and the RMA process has not been great, to say the least!

Today, I subitted a new RMA for the second Seasonic power supply and after filling out all the required information, I received a message saying " RMA Process Status: Serial number is in RMA process or has been serviced before".

I had to send an email to their customer support saying:
"My power supply is still under waranty and I received a replacement for the same power supply before. AS I said in the new RMA request "The power supply worked fine for many months and then started shutting down intermittently and often. My first Seasonic power supply had a similar history.

I have since replaced with another manufacturer's power supply and have not had any issues".

On my first RMA exchange, I received the wrong power supply and it had a big dent in the grill. I had to escalate to person in Seasonic Europe and they finally got it right.

Other Thoughts: Seasonic make a great looking power supply, but I have not had good success with them. Maybe my experience is just an anomaly, but to have to RMA twice in 2 years with 3 years remaining on the warranty, I am going to sell off my newest RMA power supply and go with another manufacturer!

Manufacturer Response:

Hi Mark,
I am sorry to read of your experience with our product and service. I am sorry we did not meet your expecations. If you have the same symptoms with the 2nd replacement power supply, perhaps the issue might be non-PSU related? I hope you have started the RMA with Sea Sonic USA and I hope that it went smoothly after the initial hiccup. If you have any comments or concerns, please contact me at: newegg@seasonicus.com Thank you

5 out of 5 eggsAwesome.

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: So far this thing has barely kicked on its fan, I did a little stress testing and it just keeps rockin'. Although this is way over kill right now because my GPU has not shown up yet. Still looks solid, and is kinda heavy. I like the modular design, I didn't have the same issue as I have read on here with the plugs being hard to plug in.

Cons: Its my fault but I didn't realize this PSU was so long and it doesn't actually fit in my ATX Mid case. My PSU mounts in the front and it runs into the MOBO if you attempt to push it all the way in. So I have an excuse to upgrade my 8 year old case! I'm gonna miss the old girl.

5 out of 5 eggsWorks great

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: - Nice packaging
- Great modular options
- Looks nice
- Quiet

Cons: None so far

Other Thoughts: This is way overkill for my hardware and I probably would not have bought it at its normal price but got it for a great price so it now gives me plenty of room to grow for a while.

5 out of 5 eggsSmooth Power: Excellent PSU

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: 1250 Watts for all your needs: Crossfire or SLI. Very good gold unit (rivals some Platinum units).

Cons: This is the 2012 model, not the most current 2o14 model.

Still is is a great performer.

Other Thoughts: For gamers and enthusiasts only: you don't need to power the USSR if you are only web surfing and some occasional apps.

5 out of 5 eggsPower to the moon

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It's quiet and feeds my hungry motherboard nicely. Packaging is awesome. LOTS of room for expansion. I got it for like half off... and plan to SLI in the future. If you have big power needs, this will satisfy.

Cons: Packaging is awesome... although I'm not sure I need my PSU wrapped in a velvet bag.

Other Thoughts: This PSU is primo! Its very quiet and works well, can't really ask for more. It also comes with an awesome cable pouch / lunch box. With the cables you don't need, you can bundle them up in a drawer for future use. Take the gold pouch it came in and use it to hold your lunch! It will hold a water bottle, snacks and sandwiches quite well.

This review is from: SeaSonic X-1250 ( SS-1250XM2 ) 1250W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Awesome PSU from a great company, no surprises here; Seasonic is my go-to company, each and every time.

Stressed everything I could to get the fan on and couldn't push it hard enough.

Cons: Nothing at all.

Other Thoughts: Great shipping and packaging from NewEgg.
Over-spec'd for my use.

Other Thoughts: sad i had all wires single sleeved , hours of work and they probably will not work with the new power supply i have to buy now going to Enermax, are corsair

Manufacturer Response:

Hi John, sorry for the inconvenience of the RMA. Please contact our service at www.seasonicusa.com and they will help with the RMA processing. Please note, to connect the R9 VGA, please use single dediated PCIe cable per single PCIe power port so you will use 2 different cables to power the VGA. Thank you and if you have any questions or concerns, please contact me at newegg@seasonicus.com
