1 out of 5 eggsPSU Failed just after warranty expired

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: Cheap. It worked well while it lasted.

Cons: Three weeks after the warranty expired, it failed. It sounded like fireworks, and my machine was suddenly off. I removed the psu from the machine to find a green capacitor cap fall out of it.

Other Thoughts: I original thought it was still under warranty. Tech support was very courteous, but informed me it was just out of warranty.

3 out of 5 eggsIt worked fine for about 2 1/2 months.

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: -It wasn't incredibly loud
-Nice sleek black design
-Plenty of SATA cables

Cons: - 2 1/2 MONTHS!

2 1/2 MONTHS! 40$!

Other Thoughts: I used my HT/Gaming PC on occasion, as I would usually be at work/school. I frequently kept it off. One morning while getting ready for school, I needed to check on a website for some information. When I pressed the power button, nothing came on. I switched power cables and made sure everything was plugged it. It still didn't work so I waited to troubleshoot it in the afternoon. When I hooked up another PSU, it worked.

I expected a 40 dollar PSU to last longer than that, especially coming from Rosewill.

1 out of 5 eggs

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: Cheap power supply.

Cons: Died after 1 month of heavy use. Will not recommend for gaming even if its a low end system.

Other Thoughts: Look for trusted brands, never overlook a power supply as it could take down other important components as well.

5 out of 5 eggsGood PowerSupply

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: Good power supply. It does what it supposed to do.
Silent.

Cons: 8 pin cable is short if you have bottom PS case layout. So you need extension 8 pin power cable

5 out of 5 eggsAwesome for the money

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: I have used this in two builds, and it is still going strong. I took a chance on Rosewill and I am happy I did.

Cons: None.

Other Thoughts: I will need to upgrade soon due to upgrading my Graphics card again, it will probably be a Rosewill.

5 out of 5 eggsWhat I needed

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: Quiet

Cons: Not modular.

Other Thoughts: Works for what I needed on my fathers older Dell. A replacement 375w from Dell was going to cost him $100. I was able to get this to fit in the Dell case with a little creativity and it works just as good for a fraction of the cost. I would recommend to anyone needing a basic PSU replacement.

2 out of 5 eggsPick a Different One

This review is from: Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

Pros: It works.

Cons: Sata connectors are very tight, dangerously tight.
You have to push in hard and you can break your HDD or optical drive, it's very risky.

Other Thoughts: I do not recommend this PSU.

Manufacturer Response:

Dear Valued Customer,
Thank you very much for purchasing this unit.
We strive to provide the most reliable and highest quality products to our customers.

The connectors should be snug fit to the peripherals. If you experiencing problems with some of the connectors you may need to warranty the product for defects. Please contact our support team to assist you with warranty options.
