Needed a good quality, preferrably silent PSU for a workstation build with an i7-10700K, 64GB ram, GTX1080 and 7 SSD's. I'll be replacing the GPU with a 3080 if I can ever find one to buy at normal prices, so also needed a bit of future-proofing for that. This PSU reviewed very well everywhere, and while it's at the higher end of the price scale for a 750W, it's clearly a quality bit of kit.Comes very well packaged. This is the latest 2018 revision, so has all the modular cables you're likely to need, including 2x 4/8 pin 12v motherboard connectors if you need them both for overclocking. Nice little bag for spare cables, and some cable ties too. Operation is silent, the eco fan mode means it only comes on when needed, and I don't think I've ever seen it come on ... MoreNeeded a good quality, preferrably silent PSU for a workstation build with an i7-10700K, 64GB ram, GTX1080 and 7 SSD's.

As long as you have a large case this shouldn't be a problem, although they made it a bit touch and go feeding the 12v cable round the back of the MB to the top in a Fractal Design R6. All's good though, after using a little thought and care.So far, very pleased with this unit. It just sits there and does what it's meant to do. An added bonus is the 10 year warranty, unusual these days and hopefully shows Corsair's confidence in their product's longevity. I prefer PSU's that last at least a decade :)

Another Great Mid-range Corsair Power Supply, Mostly

What can be said about the RMx series? This is another solid mid-range entry from Corsair that's sure to last the life of your PC. If not, it's backed by one of the best warranty's in the business. No issues getting up and running in a few minutes, cables were strong, but flexible. I'm still a little annoyed Corsair doesn't include all braided cables, but those are easy enough to replace if you want to go for that super-clean look. The power supply fired up and performed perfectly at idle and under load, no issues with whining caps, noise in the power line, or other issues some mid-range PSU's tend to exhibit. If Corsair built this thing to a price point, it certainly doesn't show. Bottom line, if I could give an extra half Egg to the RM-750x, I absolutely would - ... MoreWhat can be said about the RMx series?

Bottom line, if I could give an extra half Egg to the RM-750x, I absolutely would - it's only faulted by a few nit-picky issues and stuff we're somewhat used to at this price point. I subtracted one Egg for the lack of all braided cables, and the lack of that fan test button which, in my opinion, should be mandatory for any PSU with a zero RPM fan mode! At the end of the day this PSU breathed new life into an old HTPC for me, and the PSU will likely out-last all of the components in the machine.

Good so far

Out of all the failures I have had, the PS is the most frequent, followed by hard drives, Logitech wireless mice and un-maintained water cooling systems. You never know when they are going to fail. I personally have never had a PS fail on day 1, but I have seen anywhere from 1 month to 2 years. The ones I have seen go, go up in flames!... well at least sparks and burny smells. I always worry it might burn the house down if I am not there, and usually I am not. Some have just degraded to the point of causing strange behavior – which is really hard to troubleshoot. The few I have diagnosed turned out to be due to capacitors, usually bulging, but sometimes exploded. If this model’s “Japanese capacitors” are truly better, then I will be happy. If any PS makes it beyond ... MoreOut of all the failures I have had, the PS is the most frequent, followed by hard drives, Logitech wireless mice and un-maintained water cooling systems.

The few I have diagnosed turned out to be due to capacitors, usually bulging, but sometimes exploded. If this model’s “Japanese capacitors” are truly better, then I will be happy. If any PS makes it beyond two years in your exact same rig, you are probably good to go for a very long time. Since I don’t like down time, my approach to sizing the PS is to ensure my most likely point of failure can handle the peak load without breaking a sweat. That means not driving the whole or any components anywhere close to their limits. That is why I add +50% to +100% capacity to my calculated power draw to size the PS. Yes, that is right – double the capacity! Everything runs cool, quiet, more efficiently and in the mid-range of each components electrical and temperature specifications. This might cost you an extra $30 - $100 (maybe more on the super high end), but you will make some of that up in efficiency, come out way ahead when you don’t have to suffer down time and heaven forbid the rare case of burning the house down. 750W should be plenty for your average gaming rig with one decent video card. There are two PCIe cables, each with two connectors. Probably more cable than needed. Based on what I just laid out, driving multiple high-end video cards will likely lead to early failure of any 750W supply. Who knows, maybe this one is different. I gave it 4 eggs only because it has only been installed for 3 weeks. I will upgrade to 5 if it makes it to a year. Update (3/25/19) - Still working great. No complaints.

Grand Supply

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 ... MoreThis is one of the better power supplies available, if the wattage fits your needs.

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.

Great price for a great product

My previous Corsair Builder series PSU of many years expired, so it was time for a replacement, and what better way to replace than to upgrade? For a reasonable price I’ve got a Gold rated, fully-modular PSU. Less excess cables in the case, confidence in build quality and power supply, easily installed. Couldn’t be happier!

Modular, quiet, powerful and good brand.

I have used only Corsair and EVGA PSUs for the last 10 years. There are better, and there are cheaper, but there aren't any cheaper that are better and there aren't any better that are cheaper. This is the happy medium. I have had zero failures with Corsair PSUs. I am pretty sure, though not positive since I didn't open this one, that it is manufactured by CWT which is very, very good in my 35+ years building experience. It means that the caps are in very tight tolerances and the coil windings are done correctly. For this build, I tapped a family friend who has built her own gaming rig and gaming site. She has assembled a system that games pretty well, and now her focus is on the appearance. We saw that the first requirement of bling is plenty of stable power, and a ... MoreI have used only Corsair and EVGA PSUs for the last 10 years.

She has assembled a system that games pretty well, and now her focus is on the appearance. We saw that the first requirement of bling is plenty of stable power, and a modular PSU gives her that plus the ability to add colored cables, which is her next planned change. We took out a standard PSU that was good but not great. It had wires tucked everywhere. With the Corsair, we were able to eliminate about half of the cables. We also added a Lian Li sealed radiator water cooling HSF, so stringing some extra cables through and hiding those behind plates in the Lian Li case is a work in progress. You can see from the "After" pic that we have some clutter to clean up still, but it looks great with all fans lit in sync. Mia was very, very happy with the increased connectivity, the increased power, and the absolute silence of the PSU. Since I prefer PSUs made by CWT, Corsair is usually a no-brainer, and this was no exception. It just works right. Highly recommended.

PSU came in today, in its original box, and worked perfectly! Came with everything as described, I wired it up and finally got my PC up and running ag

PSU came in today, in its original box, and worked perfectly! Came with everything as described, I wired it up and finally got my PC up and running again. Would definitely recommend and Ill be returning for any PC parts I need going forward, thanks again guys!

Sufficient Reliable Power

This is my 4th Corsair unit, the 550W unit is still in my HTPC (4690K and an assorted of components to watch 4K content), with somewhat everyday use. Previously this 9900KF had a Rosewill unit which is a 650W, plenty good but given the circumstances the Corsair is a better choice overall, considering that it comes with two CPU 8pin power connectors. I definitely recommend Corsair power supplies, the in-line resistors give me that peace of mind the unit could not damage any core component. Just make sure to save the plastic bag to store the extra cables. Although I like the cutouts, obviously more air-slow.

Very Quiet, Very Efficient, Great Looking

For the past 8 years I’ve been using a Zalman ZM1000-HP Bronze. It’s been a good PSU but finally started giving me trouble recently. I recently reviewed a Rosewill 1200W 80+ Gold PSU, and then bought a Corsair HX1000i Platinum that I use in my main rig. Now I’m reviewing this RM750x Gold, so I have a decent number of recent comparisons to base a recommendation on. I measure total system power draw via a CyberPower 1500PFCLCD UPS which drives my entire system. The UPS seems to display power output in increments of 9W, so my numbers aren’t incredibly accurate, but should still give a good relative sense of comparative efficiency between these PSU’s. With the Zalman PSU my current PC build would idle @ 216W, and draw 450W under load. The Rosewill would idle @ 207W, and ... MoreFor the past 8 years I’ve been using a Zalman ZM1000-HP Bronze.

With the Zalman PSU my current PC build would idle @ 216W, and draw 450W under load. The Rosewill would idle @ 207W, and draw 441W under load. The Corsair HX1000i idles @ 198W, and draws 432W under load. Finally, this RM750x idles @ 189W, and draws 432W under load. Focusing mainly on the numbers between my Corsair HX1000i Platinum and RM750x Gold it’s interesting to see that the Gold actually gets better numbers overall. This aligns with the idea that it is more important to buy a PSU that is appropriate to your power needs than it is to spend a lot on the efficiency rating (although it’s even better to do both). A PSU’s efficiency sweet spot is typically around 50% of its rated maximum power. Since my PC stays between 200-450W I never quite reach the sweet spot for my 1000W PSU. This 750W PSU, on the other hand, is most efficient at around 375W power draw – right around where my PC sits, making the numbers slightly better. Overall I’m very pleased with this PSU. Deciding if it’s right for you depends on a few factors. 1. Is the price right for you (There are cheaper options available, the black version is currently on sale $119.89)? 2. Is it appropriate for your power needs (200-450W use range)? 3. Does it support enough hard drives (8 SATA is plenty for most folks)? 4. Does the color fit your aesthetics (white fits most schemes)? 5. Do you care to spend more for Corsair Link connectivity (HXi is what you want if that’s the case)? Ultimately as long as this model makes sense for your power needs then it’s a solid choice.

[Rewarded Review] Corsair RM 750W PSU

Bought this power supply (PSU) for my first PC build, saw that the Corsair RM series had pretty good rankings and reviews, so I decided to go with this power supply; the power supply feels pretty heavy and sturdy, like you could totally ice someone with it and the cables feel pretty high quality(you might have to break in the cables when you receive your PSU - as a novice PC builder I thought it was pretty normal to be delicate with PC hardware, but I made sure I lined up my PSU cables and they weren't seated all the way into the PSU itself, a couple searches on a forum, turns out you just had to push them in a little bit harder, lol)
