Corsair CX750M

INTRODUCTION

Long story short: My EVGA PSU made a loud air woosh sound, and it annoyed me. Not only that, but the cables on it made my cable management horrid. So, I got this for $80 at Best Buy, because most of the cables are flat, and I had a feeling that it would be quiet (like my CX430M).

 

LOOKS

Well, if you buy a Corsair power supply, you will get the Corsair treatment. The power supply itself looks nice, and it has a nice looking fan grille (although chances are you will never see it). The 24-pin cable has a decent sleeve, up until the last few centimeters, then the rainbow starts to show. The 8-pin CPU cable and all of the modular cables are those nice flat black ones like on the RM series and up, I believe. Overall, it is a really nice looking unit, especially when put up against some of the other power supplies at this price.

 

RELIABILITY

 I’ve only had this unit for about a week at this point, but it seems rock solid. Granted, I’m not pushing it that hard, but whatever. It’s under a PSU shroud and pulling air up through a fan filter which is a centimeter or just over above my fairly low carpet. And it’s happy.

 

NOISE

This thing is… WOW. I tested it in a very quiet room (my closet), and I could hear a faint fan tick and kind of rubbing sound, but other than that, it was almost inaudible. I put in my system, and legit checked all my fans (7 of them: 1x rear, 2x front, stock CPU cooler, 2 on my 7950, and then the one on the CX750M) to make sure that they were actually spinning. At idle or doing light things, my rig is almost silent, other than my stock cooler that has a tendency to sound like a very quiet supercharger, and a small woosh from my 7950. I am impressed.

 

CONNECTIVITY

The power supply is semi-modular, and always has a 24-pin motherboard power connector and an 8-pin CPU connector attached (that’s the not-so-modular part). The modular cables are as follows:

·         (2) 6+2x2? PCIe power cable (2 6+2 connectors running on a pigtail connector)

·         (2) SATA power cables (2 device)

·         (2) Molex + floppy cable (3 molex, 1 floppy)

I wish they would have made the pigtail for the PCIe connectors a centimeter or two shorter for looks, but I can see how it might be nice to relieve any possibly stress on one or more cards (depending on if both of your cards use a single connector).

 

CONCLUSION

 This PSU is amazeballs, and I love it. It’s quiet, it’s quality, it’s nice looking, and the cables don’t suck donkey. And not only that, it does have the 3 year warranty from Corsair, which is always nice. And when you can pick one of these up for $80, I think that’s a fairly good deal.

 

IS IT WORTH IT?

For sure. If my CX430M was any indication, these things are tanks. And they’re wonderful if you’re on a budget. So yeah.

You should have saved up for a G2.

It's unfortunate that the CX750M that I had for a short time had terrible coil whine whenever I moved my mouse. My brother's CX750M also does this. Do you experience this?

fix color pls?

Shit, thanks for reminding me. I typed it up in Word.

Nope. My rig is almost silent now.

Why? If you say "Because it's fully modular and gold rated and has hybrid mode," I'm going to punch you virtually.

I had a CX650M that had this problem!

next time you can just Ctrl shift v paste it , it will fix the color.

Firefox didn't let me do that. And I just started using Chrome again.

^ fixed.

 

Unless you got in on a really good sale, CX750M isn't worth the money compared to the noticeably better (Super Flower made) 750B2.

Which does NOT have full modularity, gold rating, or hybrid mode (just better build quality and warranty service), so no punchy for me.

I don't mean to be an ass, this is a nice review overall. But you really, really can't judge reliability like this.

EVGA left a sour taste in my mouth with even their low-end-of-the-high-end PSU, so buying that would kill me.

My EVGA unit was choking to death like this. And since I haven't had it that long, I decided to do that since some PSU's HATE that airflow situation. If it were like my CX430M review where I had owned it for a while, then obviously that section would have sucked less.

I think you got a bad unit, since my 850G2 has been fine. What abour RMA?

I'm not RMAing it. I just put it in Ares, since I won't hear it as much since:

A. It'll be on the floor.

B. GTX 480 POOOOOOOWWAHHHHH

C. Now I don't have to buy a CX650M for said computer.

[FatPenguin]

I am thinking of getting this PSU

 

also would you recommend running 2 970s off of this PSU

I can back that choice up.

Cause FSP sucks, and FSP made the G1 (and B1)... so blame it on FSP not EVGA lol 

 

Super Flower is amazing

At current price points the EVGA 750B2 is a better buy then this PSU. Either PSU will be fine running two 970s.

i have the same problem but its not constant it goes away for me once the pc has been on for about 30 mins

SuperFlower is love, Superflower life. Rocking a 850G2 here.  B)

For $80 you can do much better, but with this unit sometimes going on offer for around $70 it's an ok buy at that price

 

Good review either way

[RazerZ]

They're really not that reliable. The cheap capacitors in the CX series are a big downfall and can fail under moderate load. Really not ideal for a gaming PC. They are not even close to tank like build quality, if anything it's the opposite. Remember that Corsair, like many other companies, only puts their sticker on the PSU. Their OEMs include CWT, Chicony, Greatwall, and Seasonic. The Seasonics are the rock solid PSUs but are often overpriced.

 

Like anillation said, for the same price (actually even cheaper after rebate) you could have bought the Super NOVA B2 from EVGA, Super Flower OEM (the best) with build quality miles ahead of the CX.

 

While not being a firecracker, the CX series are mediocre in quality. Certainly not recommended for $80. The truth can be harsh some times, I'm just putting out there.

^{Have that exact same psu in my sons rig powering a 950 @ 4ghz, 5850s xfire and a ssd/hdd. Rock solid rails and very low noise. Got it on sale @ best buy earlier this year for $50 with a coupon.}

[Sintezza]

Corsair CX series are CWT units.

They are fine, its a good budget psu.

 

Not the best you could get, but definitely not the worst.

Nope still not worth it for $70

Keep in mind the CX750 are a different CWT platform then the other CX models, and performs better. It's more closely related to the TX and GS.
