I thought it was gonna last 7/9/2019 2:31:53 PM

Pros: Moderately priced

Cons: Literally died after 7 months

Overall Review: This power supply off as a great moderately priced PSU but after 7 months of using (more like 6) it just suddenly died. It had been shutting off for about 3 days but a simple restart would fix that problem but this morning it fully died. I went to turn my pc on and it will not turn on. I checked all the cables, checked everything i could think off. but at last it died.

Pros: -- Spot on voltages
-- SUPER quiet
-- flexible
-- self-protective

Cons: -- perhaps size, if your case is small
-- modular cable jacks could be better marked

Overall Review: This is one of the better power supplies available, if the wattage fits your needs. The quality shows in many ways: modular connections, HEAVY components (good way to judge power supplies) and it even comes wrapped like fine cognac: in a velvety, microfiber drawstring bag with cables in a nylon velcroed pouch. The supply with no cables weighs 3.5 lbs. Most cables are braided. Caps are all Japanese 105° capacitors, with their superior seal and electrolyte.

Installation is typical ATX; pick the needed cables, plug in, and go. Modular means you shouldn't have the huge snake of unused cables stuffed somewhere. But make sure your case can tolerate the somewhat long 6.25” case (+ any modular connector). The cables are a generous 18” - 24” long. A dozen cable ties are included.

It boots silently; I could only hear the fan if my ear was right next to the box when drawing significant wattage. The power good signal is produced in 200ms and the voltages are well within tolerance and rock steady: 5V line measures 4.9V, 3.3V line measures 3.2V and the 12V lines are 12V-- again an indication of Corsair’s quality design. There is over voltage protection, but also over-current, over-temperature, and short-circuit protections. I intentionally did a few tests that would blow out a lesser supply. The RM550x simply made a soft click and went black, then came on when safe. Very nice. The real test now will be how long it gives service. With a 10 year warranty, I’m not worried.

i should have got a better psu 7/11/2018 1:20:44 AM

Pros: it was a good battery for the price

Cons: after 1 1/2 years of use today it starting giving my PC power surges. and I am in need of a new one

Overall Review: it lasted long days with it on for gaming, and gave no issues till today. even tho I said 1 1/2 years it was more of a year as I didn't use it much this year as I am going back to school and don't have the time for gaming

Good PSU, but less than expected. 6/24/2018 7:56:40 AM

Pros: Consistent stable power…
Fully modular PSU at a low price…
Silent!!! The fan turns off after initial startup and rarely ever comes on…
Good quality stranded cables.

Cons: Not really any*

Overall Review: This really is a nice PSU for the price. I was surprised to find normal heavy gauge stranded cables instead of the ribbon cables my previous Corsair PSU's came with.

As mentioned earlier this thing is completely silent after startup, the fan is temperature controlled and has never came on except under extreme loads.

*My only issue with this PSU is the location of the cable ports. I didn't pay close enough attention when looking at the photos because all the connectors are located along the bottom edge… This prevented me from installing it with the fan up like I prefer.

I usually use the PSU as a extra exhaust, but since this one doesn't have Corsair LINK it really doesn't matter.

In hindsight, I wish I had purchased a different PSU but this one is working great so it's a keeper.

Easy installation 3/13/2018 1:10:47 AM

Pros: It was powering an AMD FX8350 for a few months until the Ryzen builds were ready. Now it's powering an AMD Ryzen 5 1600X in a new case. The spare connector cables stow away nicely (out of the way) in their own bag. The PSU has been quiet, only turning on as needed and even then barely noticeable.

Cons: None

Overall Review: Hope to get many years out of the Corsair supplies we are running in all of our computers now
