Corsair RMx Series, RM750x, 750W, Fully Modular Power Supply, 80 PLUS Gold Certified, 10 year warranty

The Corsair RM Series is absolutely outstanding from its 80-Plus certification to its CONTINUOUS power ratings to its nearly silent operation plus it truly is fully modular.SILENT OPERATIONThe RM series doesn't turn on the fan as long as the computer is using less than 40% of the power output. This means, unless you're beating the heck out of your machine with Maya 3-D modeling or using the entire Adobe Creative Suite at the same time, you will hear NO NOISE from your power supply. I selected this power supply for a whisper-silent build using a NZXT H630 Case, Nexus fans, and a Cooler Master Hyper 212 CPU cooler along with SSDs, so I wanted quiet. The RM series does not disappoint.CONTINUOUS 80 PLUS POWERWhen you're selecting a power supply, it is absolutely CRITICAL that you select a supply with a CONTINUOUS power rating, not a PEAK power rating. Continuous means the power supply delivers its power rating the entire time it's on with no dipping. Peak power ratings mean that the power supply can hit that power rating briefly, but cannot sustain that power delivery. If you're talking about gaming video cards and/or running lots of drives, you want continuous power. 80-Plus certification means the power supply runs efficiently, doing the best it can to use as little power as necessary so your utility bills don't skyrocket.FULLY MODULARI've been using "modular" power supplies for a few years now, and I've discovered that modular can mean different things to different manufacturers. Some manufacturers believe that modular means that the accessory plugs can be added and taken away, but your main cables such as mobo power and at least one 6-pin power rail are going to permanently attached to the power supply. Not so with the Corsair RM series. You can pick and choose exactly what you want to run off the power supply.Why is this a big benefit? For the majority of users, it's not. Sure, it's cool to fully customize your power supply, but if it's the only PSU in the box, you'll want to run the mobo power cables, for sure. Where fully modular PSUs are neat is in options: imagine you want to run a triple or quad SLI/Crossfire rig with four SSDs in RAID with four 3TB/4TB HDDs for data? You're going to need a TON of power, possibly more than a single power supply can deliver, but, you won't need two power supplies delivering power to the mobo. Now, you can run two PSUs with only one delivering power to the mobo while the other delivers power to all the HDDs, for example.OVERALLThe Corsair RM Series is quite possibly the best solution on the market currently for power users who don't want to sacrifice silence for performance. The RM series truly gives the best of all worlds by offering quiet, consistent power at a truly reasonable price.

Got this a day early, came protected with bubble packaging (not to be confused with bubble wrap) the cables are all a sleek black, nothing came damaged.I plugged it into an old Dell XPS 420 that had a dead PSU for a test, it revived the 8 year old system with no problems. Plan on getting a cheap one for that though. This beauty of a PSU is meant for my main rig I'm in the middle of building. I mounted it in my 300r with no problems, managed to wire the cables with no problem other than having to push the connectors into the PSU a bit harder than my fingers would've liked, but that's just me, I'm gentle. Just push them till they click. Cable management was made easy with the zip ties they include, they actually included twice as many as I actually needed, and I'm on my first build, I feel like I used quite a bit.When I tested the PSU on the Dell, it ran beautifully, the system probably drew no more than about 200W and my PSU barely got warm. Thanks to the Zero RPM fan mode, it never even made a sound, the giant cooler on the Q6600 was the only thing I could hear.If you just need a power supply, get a CX series. If you care about your components, get a RM or even Hx/AX series. I would reccomend this PSU to anybody in need of a high end power supply capable of keeping your system alive until the end of your rigs days. I plan to use this model of PSU on any build I do in the future.

I love this. The company knows how to make a good first impression. The packaging was 1st class and well designed. I immediately was reassured that I made the right decision. The power supply was easy to install and I LOVE the modular power attachments. Really helps with cable management and keeping you build looking neat and orderly. It is quiet (although I have it in a noise deadening box so your experience may vary. It provides all the power I need.

First of all the PSU didn't show up DOA it worked just fine during normal use, however, it was one of the defective units (This pertains to the 750w and 850w models) which was very apparent when the fan didn't even spin up when my system was running full bore (FX 8350 overclocked to 4.4ish and GTX 770). This thing is nothing but a ticking time bomb, well at least the lot numbers under 1341 apparently. Furthermore, when I did use it I felt like my system was throttles back slightly because the performance coming from my system was less than stellar which I believe is from the droop on the +12v rail, this coming from a configuration that had the same overclocked FX 8350 coupled with a GTX 660. The deviation on the +12v rail was despicable as well. My CX500 maintained 12.055 while the RM750 barely maintained 11.9 while idle, under load it of course didn't look any better-which doesn't make much sense for a PSU that is supposed to surpass my systems power requirements.The cables were a pain to work with, the 24 pin and CPU cables being the biggest pain to work with because of the way there is multiple ribbons to one cable that twist every which way when trying to route the cables through grommets in the motherboard tray. The other cables are manageable but the 24 pin and CPU power (Which should be normal braided and possibly pre-attached to the power supply, because they are used all the time anyway...) are very difficult to work with and place a lot of stress on the motherboard headers as well.I expected much better from Corsair because my CX500m has been running like a champ for close to a year and I quite like my Corsair fans and H60 CPU cooler, however they cut corners big time with this particular series, or at least the 750w and 850w models. I cannot speak for the quality of the other wattages available (Which were produced by separate OEMs than the 750 and 850 watt models), however I would steer clear from the 750w and 850w models unless you receive a model from lot 1341 or above.
