5 out of 5 eggs5 Years of Service

This review is from: Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Pros: Has enough cables for most uses
Is quiet
Doesn't build excessive heat

Cons: The cables can be stiff and a little difficult to position, making this a poor choice for smaller cases.
One cable is live and uncovered and in my case, would shut it down when it touched the case. (I never determined what it was supposed to power)

Other Thoughts: I used this power supply for 5 years with little trouble but for some wrangling of the cables to keep them from resting on my video card or pressing against the motherboard.

I had to replace it earlier this year due to some of the cables developing shorts and no longer providing full power to several components including my boot drive, my optical drive, and I think my motherboard, too.

If you have good space in your case and aren't planning to upgrade too often, this should be a solid power supply for most needs. If you're going to be going inside to upgrade or replace components to keep up to date, however, the cables stiffness might cause issues, and maneuvering them might be what caused mine to eventually short out.

3 out of 5 eggsLasted just 5 yrs

This review is from: Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Pros: Quiet, cheap, wire sleeves.

Cons: This PS lasted just a little over 5 yrs before it died today. I bought this originally to ensure there was plenty of power for a newer video card and memory upgrades (the OEM was 255W and noisy). Our PC is used for normal everyday computing and we are not gamers so I expected this to last more than 5 yrs. I replaced it with my OEM PS and now the PC powers up just fine.

Other Thoughts: I am tempted to buy another one of these since I really liked the one I bought and never had any issues until today. However, chances are I'll probably buy a different brand.

5 out of 5 eggsHave used several since 2008

This review is from: Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Pros: I've used this unit in multiple builds starting in 2008. I have never had one fail. I just recently sold the original unit I bought back in 2008 which was still 100% functional.

Cons: I would prefer a modular PSU for better cable management, but that's a minor gripe.

Other Thoughts: It's always important to have reliable PSU. If a PSU dies, sometimes it can take your entire build with it and if can destroy components attached to it. This unit is my go-to for mid-level builds (business/office/light-mid gaming). This card wont be powering multiple SLI/Crossfire cards or 8 hard drives in RAID, but it will cover most of your every needs.

1 out of 5 eggsDose not work

This review is from: Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Pros: None

Cons: The device dose not actually deliver the 450w of power as advertised the system i put it in only requires about 250w of power i thought that a power supply advertised to provide 450w of power would do so at least 300w but as soon as the system is under any kind of load with this power supply it shuts down due to lack of power

Other Thoughts: it would be nice for the price even great if it actually worked

5 out of 5 eggsGets the job done.

This review is from: Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Pros: Low cost
solid performance
runs cool

Cons: None

Other Thoughts: For what I purchased it for, I really went by reviews left by others.

I bought this for a replacement for a friend in need, as their PSU went kaput. Since it is not my PC in front of me, testing it was quite difficult.

But, in a nutshell, she was happy, it still works, keeps her machine cooler according to her, and, quite frankly, gets the job done.
