Corsair Power Supplies , RM 750W

This review is based on the Corsair RM Series 750 Watt ATX/EPS 80PLUS Gold-Certified Power Supply (CP-9020055-NA RM750)I have bought this power supply after my friend recommended it to me for use in my custom gaming computer. So far I am not having any issues with it, and I would recommend this if you're into quietness, and performance. This review will cover several aspects of this device such as Noise Level, Design, Quality, and Support!First off is the Noise Level. The Corsair RM 750 Watt 80plus Gold Power Supply Unit is very quiet. I'm using around 377 watts, according to PC Part Picker. This PSU unit is a must if you want a build for quietness because it has a Zero RPM Fan Mode. This occurs when your not using a big load on the unit.The design of this PSU works for me. It's fully modular, which means you don't have any wires coming out from the back. You can choose what cables you want in the case and it's great for better air flow. This is the main reason why I choose this model. All of the cables work with my build and they work fine.Corsair uses quality products in all of their products. This is the reason why I'm stuck with them. The RM750 has high quality transformers and capacitors which means for starters, you won't hear any noise coming from the unit its self. It delivers clean, and stable power. I am using an APC UPS for backup power because in my area, blackouts are often. I can run my 377 watt system fine from the UPS for 45 minutes.I have yet to contact Corsair's support team because the power supply works great for what I need! While I was looking through reviews they seemed very good. I'm pretty sure you won't have to call them, or Amazon when you buy this product.So in conclusion, this product is a plus, and I would recommend it to anyone who needs a reliable, and efficient power supply!

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.
