Corsair Platinum Modular Power Supply 750 W

Dead silent!The media could not be loaded.I bought this to replace my old Seasonic PSU which was getting a bit too noisy and so far it is doing a fantastic job. My primary reason for buying the 1000W version was to keep my system load at around (or below) 50%. This ensures the best efficiency and also the fan doesn't spin.You can hook it up to an internal USB port and view details on Corsair Link or iCue, which is a very nice feature. The only I don't like is that the test fan option is only available via the physical switch on the PSU and not from the software.The cables are very long and flat, which helps with management in tight cases. So far I can't hear any coil whine or any other noises coming from the PSU.I've included a video of the system powering up ... MoreDead silent!The media could not be loaded.I bought this to replace my old Seasonic PSU which was getting a bit too noisy and so far it is doing a fantastic job.

5/6 Corsair Products DOAs

This is the 6th time I have purchased corsair products mostly including ram for friends computers and a Force gs ssd. To date only the ssd functions like it should have. Anyway I had broke down and decided to give Corsair another chance after my raidmax power supply died after 6 months of use. This time around after doing my research and reading hundreds of the thousands of positive reviews on this product I decided it was time to buy my first "high quality" psu for my gaming rig and give Corsair another chance. After unboxing and installing in my rig the moment I had pressed the power button a loud snapping sound started and massive sparks started shooting out from the inside of the power supply. I had quickly unplugged the ps and reinstalled an old no name 500 ... MoreThis is the 6th time I have purchased corsair products mostly including ram for friends computers and a Force gs ssd.

After unboxing and installing in my rig the moment I had pressed the power button a loud snapping sound started and massive sparks started shooting out from the inside of the power supply. I had quickly unplugged the ps and reinstalled an old no name 500 watt psu that came with my case. Took me a while of resetting the cmos and reseating memory to get my computer to boot again. I can only hope that my computer is not damaged but something tells me to expect that I am out of luck here. Corsair if your reading this my faith in your company is gone, your products look great but your ability to produce a product with the quality standards you claim to have is ridiculous. My misplaced judgment deciding to give your company another shot in hopes to receive a quality power supply that would extend my computers life has backfired in a way that I may be without a computer altogether. To anyone that it may concern my computer components are not pulling anyway near the 850 watts advertised for this power supply.

Best when on-sale

I bought this back in October 2013 while it was on sale to replace an old multi-rail 650W beast that was failing to boot intermittently. I actually just cannibalized the HX750 this week for a new build that I bought a Cooler Master V750 for but the CM ended having a lot of coil whine come out of an open case. I would have gotten another HX750 but it wasn't on sale when I ordered my parts. I don't know if it's worth the extra 50-60% premium when it's not on sale... The new build is in a new Rosewill Challenger U3 mid-tower ATX case (#N82E16811147060), but I couldn't get most of the mounting screw holes the line up. Also the fan doesn't line up very well with the smaller bottom vent on the Challenger U3, so I will have to keep an eye on the temps. On an Asus Z97-A ... MoreI bought this back in October 2013 while it was on sale to replace an old multi-rail 650W beast that was failing to boot intermittently.

Also the fan doesn't line up very well with the smaller bottom vent on the Challenger U3, so I will have to keep an eye on the temps. On an Asus Z97-A mobo the EATX 8-pin 12V header is in the upper left corner of the mobo. The CM V750 doesn't have a long enough EATX 8-pin 12V cable to comfortably thread it through the mobo backplate of the Challenger U3 case without rubbing against the RAM sticks on the upper right corner of the mobo. The HX 750 does have enough room to curve around the edge of the mobo in this configuration! There are a bunch of cheaper 750W PSUs with same or higher quality internals out there so there HX750's value is questionable for its premium fringe benefits when it's not on sale.

Great power supply. My only complaint is the AC connector to the wall. It is a two prong, American style plug. The problem is the ground is just a green wire hanging off the end. You could attach the ground to an AC outlet mount for ground, but a common UPS doesn't have this. So, I had to buy aftermarket (this isn't a standard PC plug, it's big and square). Tripp Lite Heavy-Duty Power Cord, 15A, 14AWG )IEC-320-C19 to NEMA 5-15p). 10 ft. (p034-010). This is why I gave "Easy to install" One star. If you pay $800 for a power supply, you shouldn't have to purchase aftermarket cords to make it plug into AC power properly.

Inaccurate number of modular ports in product photo. The "NO LINK Compatibility" HX750 I received is a pretty nice modular PSU, but instead of the pictured five PCI-E 6+2 connections, there are only four available. Since this section of the PSU is labeled "PCI-E 6+2 / CPU 4+4" that means you only have three connectors for PCI-E and one needed for CPU power. Granted, the included PCI-E cables double up with two ends each, but that just means you are doubling draw on one cable for two cards, probably not advisable for power-hungry multi-card setups. That's the only thing that doesn't make this 5 stars. The product is not depicted correctly on the site, and would have changed my buying decision.

It may have changed my mind about modular

"I love the smell of new PSUs in the morning." OK, anytime really ;) Seriously, buying a Corsair power supply is never a question in and of itself, but I really debated about modular. My experience with modular has been less than stellar. I have purchased a few in the past, in all cases a known brand that reviewed well. And, in all cases, I had initial or eventual issues with the SATA cables. With two of them, the issue was that one of the SATA connectors on the strand was bad and couldn't be used. Not too hard to work-around, but disappointing since modular power supplies are usually touted as a premium option. The last issue I had with one was that the whole SATA cable (more likely the internal feed) was intermittently failing. It took a fair amount of ... More"I love the smell of new PSUs in the morning."

The last issue I had with one was that the whole SATA cable (more likely the internal feed) was intermittently failing. It took a fair amount of troubleshooting to determine that it wasn't the hard drive, so you can see why I am apprehensive. Enter the HX650. I do a fair amount of Video Editing and have two main i5 rigs plus another Phenom II X4 that I keep running a fair amount. One i5 has an HX850 (awesome, but a bit overkill for air cooling) the other i5 has an HX750 (maybe a bit more than is needed, but quiet & efficient). This HX650 went into the Phenom II X4 rig that has 4 SATA optical + 4 SATA HDDs, plus some add-on power needs, and it is perfect for that setup. I have been running it hard for several weeks and have had no SATA problems. So, I guess my future rule will be modular only if it is a Corsair. 5 eggs for Corsair goodness and changing my thinking about modular.

MUST BUY! great for Crypto miners to run 24/7 everyday of the week with their 10+ 1080 ti rig config (2 PSU needed). The efficiency im getting running 10x 1080 ti is 93-94%. This PSU came out on January 2018 and has better tech then the typical EVGA Supernova 1600 which came out 2014 which was 4years ago. Its very quite! its compact, and they use GALLIUM NITRIDE for their transistors and everyone will follow suit. Voltage regulation is awesome through their corsair link. Along with the cords it comes with, if you know your not going to use 3 or 4 of the cords, you can sell them for $15+ each online to recoup some cost. But jokes a side, this is a great power supply, even if your not a crypto miner, this is by far one of the best PSU for gamers too, and everyone ... MoreMUST BUY! great for Crypto miners to run 24/7 everyday of the week with their 10+ 1080 ti rig config (2 PSU needed).

Contacted support which was friendly and prompt with my exchange for a new one which was within the first 2 months of the build/purchase. Fast forward 2+ years and the replacement has been a tank. I've made two separate builds with some adjustments during the first build (with replacement MSI motherboard) before getting tired of the troubles keeping a stable overclock and switching to the ASUS motherboard and adding a second graphics card and SSD. Throughout this entire time I've not had one issue with spikes (though I do have a trusted surge supressor) and even after setting up a SLI and overclocking it is still runs smoothly and better with the higher load. There are plenty of cables that even include molex and sata connectors. This allowed me to be pretty effective at reducing the amount of cables in a crowded case. When adding the second graphics card I read over the manual which reminded me that you have to put both (1 pair) of the non-modular 6+2 connectors into a single graphics card and use the modular cables to power the second one. With multiple fans and drives all running at once, at times I've had over 6 virtual machines running of different types and OSes, from having 2 to 3 screens connected running different movies. I've stressed my builds as much as I can and this is the foundation I seemed to build them on. Definitely recommend if the price is within your budget. I believe I got this with the CPU when I first purchased it. Never regretted it.

Silent under low load!

My computer is silent thanks in part to this power supply. I calculated the overall power consumption of my other parts, and they're well underneath the minimum threshold for this PSU's most quiet operating mode. I'm so happy with this. The cables turned well and let me set up a legendarily well-managed system. I have.. literally zero cables crossing over the motherboard. The ends have wires that peek out, and that let me bend quite aggressively to get cables around the outside edges of my motherboard.
