Cords are ridiculously short! Insane. 7/27/2020 11:27:44 AM

Cons: Cords way too short.

Overall Review: MB: MSI MAG B550M MORTAR WIFI AM4 AMD B550 SATA 6Gb/s Micro ATX AMD Motherboard
Case: darkFlash DLM21 MESH

Building in a micro-ATX case so it isn't like I need a full size PS, but I guess I did compared to this one. Tore the box pretty good opening it, so hope Newegg still accepts the return. The power/cpu cords are just way too short, and there's no good reason for it, imo.

Hello Marcus,

The reason for the cords being short is that this unit is meant for tiny cases and the cables' slack from longer cables wouldn't be the best in a system like that.

Cables are too short for Mid Tower 5/23/2020 4:16:50 AM

Pros: Can't evaluate yet

Cons: cables are too short to reach the power supply in a mid tower setup

Overall Review: Got this PSU as part of a full DYI build for a computer with my 15 years old son as a gift for his 15th Birthday, only to discover that as we are finalizing the build the 2 ATX power cables the 24 pin and the 12v 8 pin cables are too short to reach the PSU. I am at loss for what can be done?!

Great PSU for small form factor cases 5/22/2020 6:20:03 AM

Pros: Size, modular, silent mode, and quality

Cons: .

Overall Review: Love this power supply, I've almost never had the fan kick on because of the built in silent mode, and it is super small and works really well in a SilverstoneSG13.

Hi Ryan,

What seems to have been the specific issues you had with the PSU as advertised? The cables are indeed very short, they're meant to be used in a mini ITX case, so that would be by design.

If you have functionality problems, please contact us at any time: support.corsair.com

Nice high quality efficient Corsair psu. 3/24/2020 5:41:02 PM

Pros: - Individually braided psu cables.
- Very quiet and efficient psu.
- 10 year warranty

Cons: - My only worry is the fan staying off until a certain load is achieved. I worry about the internal components getting really hot because of no airflow. I wonder why they just do not have the fan spin at 600rpm so some air is flowing at idle loads. A low fan rpm like that cannot make that much noise. I mount mine fan up in my cases to promote convection cooling.

Overall Review: Corsair's higher end psus are my favorite power supplies. Especially with being able to replace the psu cables with ones that are different colors.

Great buy! 12/13/2019 6:29:01 AM

Overall Review: It seems like SFX power supply prices have gone up in recent years. But, at least this one comes with nice individually sleeved cables, making them easier to maneuver in a mini ITX case.
