5 out of 5 eggsSilent very efficient power supply

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I'm using this power supply to power my home server which consist of a i7-860 processor with 8gB of ram, 4 4tb wd red drives for the main raid array and 2 4tb backup drives.

With all of these compoents I'm still averaging around 40-45 mB when I'm not stressing the system. This is down from around 55-60 with my older corsair bronze certified power supply!

Cons: None

Pros: Silent, Running almost 4 years no issues, System is always on. Easy installation

5 out of 5 eggsSolid PSU, Obviously Silent

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: *Silent
*Solid
*Plenty of length on Modular cables

Just picked up my second SeaSonic Fanless. First one is in a gaming rig, the second is now in a file server. Working great.

Cons: No Negatives, Price is a bit steep, but if Silence is your goal, its worth it.

Other Thoughts: I've got two, a 520w and a 400w. Both are working great.

1 out of 5 eggsDead after 7 months

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Silent when it worked.

Cons: Expensive and unreliable. It took me awhile to figure out that the PSU was dying. My pc would continuously freeze, at least everyother day. The unit died at the beginning of Jun 2014 The first time ever that I have problems with a PSU. Out of $100+.

Pros: None... Never got to test it.

Cons: DOA... Powers on for 2 seconds then makes a slight popping sound and shuts off.

Other Thoughts: Should have paid more attention to everybody elses failures on the reviews... thought I might get lucky but I knew it was a risk... won't buy another.

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great PSU, stable voltage and stays cool.

Cons: This PSU is slightly longer than the standard PSUs due to the modular design and connectors. It didn't fit nicely inside LIAN LI PC-Q25A case.

5 out of 5 eggsTotal Silence and High Efficiency

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: This is the best PSU I have ever owned. Not only is it totally silent (it has no fan), but it is 80 PLUS Platinum. That is as efficient as any available desktop PSU.

Furthermore, the cables are individually attached to and removable from the PSU. That means you only attach the ones you need, and if you need to upgrade the PSU to another Seasonic, you can just leave the components connected and reattach the cables to the new, larger PSU.

Cons: Very expensive.
