2 out of 5 eggsGo with a better brand

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

Pros: Quiet

Cons: Shuts off abruptly, not reliable

Other Thoughts: I selected this Rosewill Stallion as a replacement for another Rosewill power supply that developed a loud fan. Fast forward two years later, and this has begun to shut down all of a sudden. I run it in a server that must stay up 24/7, and in that, this one has failed. It is getting adequate cooling, and it is not being drained, yet it will stay up for only up for only about 3-5 days at a time without shutting down. It is powering a basic motherboard with no additional video card or other high drain additions. This has been my last purchase of a Rosewill power supply. Going forward, I will stick with name brands.

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

Pros: Nice price and good size.

Cons: DOA.

Other Thoughts: After testing the power supply on two working motherboards with no results, I accepted that it was DOA. I'll be purchasing my next power supply from another brand.

5 out of 5 eggs6 years, still going

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

Pros: I've killed plenty of cheap power supplies over the last 20 years, didn't expect a $40 PSU to last, honestly. 6 years later, this one is still going. Looks good, works great (as long as you don't overload it) and very quiet.

Cons: The cables are very plentiful and long, so took some cramming to get it into a small MATX case. No complaints otherwise.

Other Thoughts: Hard to think of a reason you couldn't use this for a low-power PC.

This review is from: Rosewill Stallion Series RD400-2-SB - 400-Watt 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 - 400-Watt 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
