Corsair CX750W

[Khajiit Dealer]

So I'm getting an EVGA 980 Ti SuperClocked to replace my current 660 Ti SLI setup. I already have a Corsair CX750W in my rig. I got it a little over a month ago. I know it's not the best for Gaming and is supposed to operate at 30C but I have a few questions.

1. Is there a good chance that my PSU will blow up and destroy my computer?

2. Is there a good chance my PSU will die?

3. Will this card cause my case (and PSU) to heat up more than my 2 660 Ti's?

Poor 980ti... may its bios rest in piece.

I highly recommend a good 650w PSU maybe from evga or seasonic

Thanks for answering my questions...

Thanks for answering my questions...

 

You're welcome. The only one I missed was the last. It will run cooler.

I'm only upgrading if there is impending doom, otherwise I'm sticking with this PSU as it has given me no problems.

Considering how my 660 Ti's haven't given my PSU a problem, what makes you think the 980 Ti will?

the 980 ti will run cooler than the 2 660s... but i would not spend 600+ on a gpu without upgrading the psu first, good luck

1. Very unlikely
2. What is wrong with it. 
3. No it should be less due less power draw.

The drive? Do you mean graphics drivers?

 dont mind me its 4 am... i mean psu

I never really understood the hate for this PSU. It is extremely unlikely that the thing will die/take components with it, so why do people act like I need to replace it asap?

its not made to handle the kind of load youre throwing at it, corsair even say it themselves its to be used for light loads like office work

 

plus the fact that you hear about them going out and taking other components with them all the time, there were atleast 3 in the past week

Link to the computers going out?

I've used two CX PSUs on two gaming rigs. One of them is still alive, and the other was upgraded after three years. I've had no problems with either PSUs. I wouldn't trust a CX with a highly overclocked PC, but they are not as bad as people say they are.

Mostly because they only read what other people are saying in the forum without any experience of their own. I had a CX600 with a 4690k and an r9 290 for a while. When my son starts gaming in his room, it gets up to 85 degrees in there. (Yes even with the AC on). People like to point out that is has a low temperature rating, but we didn't have any problems.

Since you have it already, my suggestion is to keep using it until the three year warranty expires. Then get something else. That's what I did. A warranty on a power supply is comforting.

"CX Series PC power supplies are an excellent choice for basic system builds and desktop PC computer upgrades. CX Series PSUs are available in a variety of power configurations, and include features that are normally found only on premium power supplies."

1 - that happened 4 times the last 2 weeks on the forum

2 - more likely than a good PSU

3 980 Ti will warm up your case quite a bit.

Chinese primary capacitors, very low quality secondary capacitors, mediocre build quality with soldering mistakes, low temperature tolerance meaning the CX600 is actually a 400W unit when used above 30-35*C. You pay little, you get cheap products.

The CX750M is by far the best in the CX series. It's a rebrand version of one of Corsair's earlier successful PSU models, unlike the CX600 and below. It handles ripple very well and doesn't fail to protect your components from power surges along with turning itself off when it overheats instead of taking down components or popping.

@EllieThePurpleFuzzy had 2 CX750 die on her - lost an i7 3770 and a 7950. The GS were maginally better but still cheap and crap.

When I look at customer reviews in various sites and compare them to reviews for premium PSU's I don't see much of a difference. The range for the CX750M from hundreds of customers is between 3.9-4.7/5. There's a chance of any PSU failing if you push it too far or live in the middle of the Sahara.

The CX are bad and the positive reviews you see are from people using them as intended - for office PCs with USB printers, not for a gaming or anything above an i3 with an iGPU.

I encourage you to look at what many people have said here: https://www.google.com/shopping/product/10269649906844494136?q=corsair+cx750m&client=ms-android-verizon&prmd=svin&sa=X&ved=0CBsQvCRqFQoTCJq46Lz6isgCFQJWPgodtWIA0Q#reviews

Pros: Very decent price for power and performance/quality. More than enough power for a Gaming/power user PC.

Looks good, Almost fully modular with sleeved cables so it is easy to manage.

Reliable. That is why I go with a Corsair PSU in a Build.

Cons: None for me in over a year of use.

the CX series is Corsairs Entry Level PSU. If your going all out and overclocking your i7 4770k and R9 290X then a CX750M is a bit light for that type of use. But for Most gaming builds this is a good buy.

How about you link some actual reviewers and not random people defending their purchase?

From HardOCP

"This unit’s current product placement is readily apparent from the outset as the build quality has issues, particularly noticeable since these are coming from a "name brand" and not a "no name" company. The 3 year warranty support is probably trying to tell us something as well. The unit is not very quiet, and the performance just falls flat as it can not complete testing."

Form TechPowerUp

 

• 3.3V rail's performance in Advanced Transient Response tests
• Really low hold-up time (too small of a bulk capacitor)
• Only two PCIe connectors
• Would like it to have higher quality capacitors in the secondary side

  "...the CapXon caps on the secondary side most likely won't keep their good performance if they work at above 40°C constantly, which I suspect to be the reason behind Corsair's conservative temperature range, at least for full continuous power output."

  CapXon caps are extremely low quality and are one of the main reasons the CX is regarded as crap.

GTX 590 . my 7950 survived.

 

 

....just

 

but as said, my 7950 barely was working great with my dieing CX750M. yet changing to a EVGA G2 850W ....suddenly made it work totally fine.

 

also i can't believe people are defending a product that is known to not be of good quality, it's not a freaking graphics card or hard drive, it's a power supply....the freaking most important component in the WHOLE SYSTEM. if it's got bad marks against it or it's a risky product...DONT buy or recommend it. simple as.

 

Seasonic with their S12ii or XFX with their Proseries are by far much better options for the price. and if you are going to be using something that will require a 750W PSU such as a multiple graphic card setup. i'd be getting a PSU that has the quality to cope with the load (such as, EVGA's G2 and GS, XFX's XTR, Seasonic's G/SSR or Cooler Masters V Series for example) rather than something cheapo.
