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.

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.

Pros: looks good

after 3 mo. running on 11/3/14 it stoped working, fan dont run , no power output , dead power supply, not sure if warrenty will cover it are not , i dont think it had the power anyway to run R9295X2 and 2 water cooling pumps
8 fans , and lights ,1 ssd, 4 HDD , motherboard is Asus maximus VII formula 4x 8GB corsair dom GT

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

1 out of 5 eggsSQUEALING NOISE! Earplugs or RMA?

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 is currently working.

Cons: Bought this to power 2 new MSI GTX 970s in SLI. Once I got the build back together, immediately noticed an intermittent, modulating squeal--sounded like a defective fan? I was sure it was one of the 4 fans on the new 970s. Unplugged each one at a time. Nope. Then left both disconnected, hit the power button to my rig and VIOLA! Squeal was still there. Yup, it's the Seasonic PSU. An irritating, super high pitched whine, like a fan bearing gone bad or I dunno--the pitch and volume change as the fan speed changes, I guess. (The squeal changes as I open and close windows, run games, etc. as the power use fluctuates, I guess?) Maybe it's not a fan? But it's working. What the H do I do now? Buy earplugs? Is it worth an RMA? Advice anyone? First time buyer of Seasonic here...Hmmm....

Other Thoughts: What the heck am I supposed to do if I RMA this and I have no PSU for the duration waiting for a replacement or whatever? Ugh.

Manufacturer Response:

Hi Warren, thank you and sorry for the inconvenience of the RMA. Please contact our USA office to start the RMA process and possibly they can do a cross ship for you. As for the electrical noise, please enable all energy savings modes in your BIOS and this should resolve your issues. If you have any questions or issues, please contact me at newegg@seasonicus.com Thank you.

4 out of 5 eggsSolid modular 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: Nice packaging, plenty of power adapters included, 1250W of power, worked great out of box (ordered two for two separate builds). Runs quiet.

Cons: Only thing that irked me was that the modular connections on the actual PSU for the motherboard and cpu power were a major pain to get to connect. It would take it as a fluke thing if it were one of them, but both I had a difficult time getting the connector to go into the PSU for those two cables. Other than that it was smooth sailing and so far so good.

Manufacturer Response:

Hi Kevin, Thank you for your review of our product and I hope the unit will serve you well. In terms of the connector fitting, it might be a bit difficut for the first go to insert the connector as the fit can be snug and the pins tight. I will pass this issue to our PM at our HQ. If you have further questions or concerns, please contact me at: newegg@seasonicus.com Thank you.
