5 out of 5 eggsWorks Great

This review is from: Rosewill Stallion Series RD400-2-SB 400W ATX 12V v2.2 Power Supply

Pros: Solid PSU, braided and sleeved cables, long 4/8-pin and 24-pin for harder to reach motherboard plugs, plenty of hook ups and quiet fan.

Cons: None

Other Thoughts: Plenty of power to run an AMD A8 7600 X4 CPU, MSI A78M-E45 Motherboard, Team Elite 16GB DDR3 1600MHz RAM and Crucial SSD.

4 out of 5 eggsGreat value, coil whine

This review is from: Rosewill Stallion Series RD400-2-SB 400W ATX 12V v2.2 Power Supply

Pros: -Looks pretty good with the chrome grill underneath and flat black, fits with plenty of builds.

-Does what it's supposed to, holding strong, will update if something changes.

-I previously never would have considered Rosewill concerning PSU's, but this product has successfully shifted my point of view. Will likely be more open-minded in the future.

Cons: -Little, tiny bit of coil whine. Not even noticeable most of the time, but when you have your head on certain angles if is very present and very annoying. NO issue for me personally, but I'm sure others may factor this in more importantly or like to avoid coil whine in any case.

I'm hoping after a break in period of a few weeks of regular use that it may go away, but who knows.

Other Thoughts: Great psu on my end, does what I need it do, reasonably priced, powers my parents home office build splendidly.

The coil whine is present though, maybe just bad luck. No problem though, but it would have been 5 eggs if the coil whine wasn't present at all

2 out of 5 eggsYou get what you pay for

This review is from: Rosewill Stallion Series RD400-2-SB 400W ATX 12V v2.2 Power Supply

Pros: I got it for $20

Cons: There are no receiving threads for the PSU mounting screws. It literally just sits in my case with no way to mount it to the case.
In other words my case is freeballing my psu.
This is made worse by the first issue, but the connection either in the inlet of the psu or in the cable they shipped it with is nearly non existent. If I bump the cord/psu at all when moving the computer dies due faulty connections in the psu/wire.

Other Thoughts: I can't say I expected better TBH. I bought it for my media PC hooked up to my TV so bumping it isn't too big of a problem as it sits in a corner with a wireless mouse/keyboard connection.
The real problem is that even though I bought a cheap power supply quality shouldn't be a lacking feature due to price, features and capabilities should. It's this business model that makes or breaks some companies like this. Yes you can make something cheap, but if you can make it reliably cheap with lacking better features for premium power supplies then you're doing it right., but to sacrafice quality as a simple "who cares it's a $20 PSU" is not the way to go.

1 out of 5 eggsCheap clips, dont buy

This review is from: Rosewill Stallion Series RD400-2-SB 400W ATX 12V v2.2 Power Supply

Pros: N/A when giving it a 1 star rating

Cons: I went through 2 of these, and on both the sata clips broke off when trying to connect them to harddrives / DVD drive. With the first one, it broke beyond fixing so I returned to newegg. The second broke off and I thought it was usable so I attempted to super glue it in place, which was a mistake because doing so did nothing, and also ruined the DVD drive I connected it to.
I did not know it ruined the DVD drive until after the 30 day return policy with newegg, so now I cannot return the power supply or DVD drive.
There are 4 sata clips, I needed all 4 to work, since 1 failed, this power supply does not work for me. A second sata clip broke disconnecting this power supply from the remaining sata device.
The clips are cheap, don't waste your time, patients or money on this power supply.
