Seasonic 500W 80+ Bronze 8/4/2019 9:01:11 AM

Pros: Won't lie, I was hesitant on buying this based on the reviews, but I'm glad I took the chance. This was the cheapest good branded 500W power supply I could find for my first build. I know its never a good idea to go "cheap" on the PSU, but so far I have no regrets. Mine is quiet and provides adequate power for all my components.

Cons: cable management. but with patience and a good case, it's possible.

I needed a replacement power supply... 7/31/2019 2:07:20 PM

Overall Review: I needed a replacement PSU for an older AMD system that uses around 370w MAX according to power supply calculators online. This unit fit the bill. I was a bit confused to not find a 120-240v selector switch on the back, but it seemed to auto-sense 120v for me. Unit works out of the box for my requirements.

Listen to the other reviews! 7/11/2019 8:00:54 PM

Overall Review: I didn't think my psu would have coil whine and even if it did, I thought it would be unnoticeable. However, boy was I wrong. This is by far one of the worst coil whines I've ever heard. It's just a continuous high pitched sound EVEN WHILE THE PC IS OFF. It might be a good price, but please don't make the mistake I did and believe it was worth it.

Not So Lucky 6/28/2019 6:17:16 PM

Pros: It powers on the computer.
Cables are all black
Looks nice
5 year warranty

Cons: High pitch whine

Overall Review: So I purchased this PSU because I thought Seasonic was a good brand and it had a rebate making the unit fairly cheap. If only I had read the reviews. I believe the reason these have such a good rebate is because they have a high chance of producing a high pitch whine. Hopefully Seasonic will start producing these with better materials or implement better quality control. I could RMA it but would it really be worth it if I have to pay shipping. I just hope I do get the rebate but regardless this will probably be my last purchase from Seasonic's cheaper PSU line.

complete failure of psu 6/26/2019 1:21:57 PM

Pros: it worked for about a year before smoking up and burning out motherboard, ssd's, a 1080 video card (for some reason my memory still worked fine). I opened the PSU to see what caused fire and it was a wire they ran near the housing of psu and vibration over time broke the sheath off the wire and shorted out the system. This PSU is extremely dangerous. DO NOT USE!

Cons: Shorted out itself after 1 year due to poor build quality. Destroyed all components of the system it was in excluding memory modules.

Overall Review: its like burning your money in the fireplace

Good unit for budget 5/26/2019 3:14:41 PM

Pros: Got this on sale for $29 after shipping and tax and a MIR. Black cables look nice in my case, and the number of connectors is sufficient for multiple fans, 2 drives, aDVD drive, and an 8 pin GPU. Fan is quiet, and power delivery is consistent enough to do some reasonable overclocking on a 1 gpu system. 5 yr warranty encourages me that I got a quality unit.

Cons: Its been 2 months since I submitted my warranty card. I received confirmation of receipt 6 weeks ago but I still have not received it. It you are relying on a MIR to justify the price then it may be worth your time to look elsewhere.
