Hi, I'm currently using the CX500 PSU and it works fine on my 8350 + 770 build, I wonder if the CX750 will have durable power supply (and not fry my mobo, CPU, or GPU) for another GTX 770?That is more than enough to the point of overkill. I do that all the time and thus the AX850w I have in here.

When I asked on other forums, they said that it's definitely not enough and has the potential to fry my hardwares if I OC my CPU or GPU, they suggest at least 850W supply or the RM750 PSU, wat's ur idea on this?

750w is enough, however the CX series power supplies are low grade tier 3, in other words they're not meant for serious systems, especially not for a sli one, the power it'll provide is enough, but the psu just isnt very good quality, if you are going to get a new psu get a better one, something like a XFX pro 750w (high tier 2) is slightly more expensive than a cx750, but it is alot better quality...DO NOT go for the CX power supply...here's a review on the XFX http://www.hardwaresecrets.com/article/XFX-PRO-750-W-Po...
when people on other forums said it'd fry your system if you oc it, they were probably talking about the quality of the capacitors used in the CX power supply, not the wattage it provides, you are at risk of slowly suffocating your system from reliable power...here's a review on a CX power supply http://www.techpowerup.com/reviews/Corsair/CX600M/

750w is plenty and there is plenty on the +12v Rail. As to the CX series, I have been around on forums for quite awhile including moderating on one and I have yet to see anything negative regarding the CX series of PSU's. In fact there are some Custom builders that are using them in their builds.

you really wanna bet your system's life on a CX psu?...look at this http://www.techpowerup.com/reviews/Corsair/CX600M/5.htm... ...the voltage regulation is more than 2%, an absolutely pathetic number and one that is highly not recommended for a high-end system (an example being a system with two gtx 770s and a power-hungry fx cpu) on the other hand, the XFX smashes the CX http://www.hardwaresecrets.com/article/XFX-PRO-750-W-Po... ...the CX is completely destroyed in cross-load tests compared to the XFX's single high quality 12v rail...the CX series is simply a bad choice, sure its better than some random 'no-brand' gunk, but that doesnt make it a good choice. You want long-lasting components working in their optimum conditions, avoid the CX line and anything below, the XFX is only a couple of dollars more anyways, while provides much much higher quality

You can easily find stuff to support a particular POV. I read a lot of it, and generally take most with a grain of salt except those that I know are reputable in theor assessment and don't have an agenda. I have been on boards for a lot of years and as I said moderated on one. I have seen a lot ot fried machines due to cheaping out on a PSU. I have yet to see anything negative regarding the CX series and I am alert to that as I have primarily used Corsair ( TX and AX ). They also have a GS and RM series, that I have not recommended and will not as I have seen issues with the RM series. Point is, I base my opinions on real world experience and not some white paper or whatever. Having said that, the XFX Pro 750 is a very good PSU and if the budget will allow for it, I would say go for it.

Although I have moved on to an AX860 to gain more headroom for my primary system, I used the RM750 with an OCed 4670K and 770 SLI with no issues, and am currently using it in a secondary build with an OCed 4770K with a single 770. I was leery of it because it had a lot of issues early on, but I think Corsair has ironed them out. I don't have any personal experience with the CX series, but have no qualms about recommending the RMs. Just my $0.02.

The one I would stay away from is the Corsair CS series as I have seen issues with those.

those models may seem good when powering your components as no visible anomalies occur and everything 'seems' to work fine. However you simply cannot dispute the 'hard facts; that testing has revealed. The power supplies blackbird mentioned are absolutely indeed low quality. People may not have heard complaints from them because they seem to work fine, but they are slowly suffocating your pc components, reducing their life spans, reducing oc potential etc. I would still strongly recommend NOT TO go with the CX...the XFX i listed earlier is one of their pro series, one of the best psus out there. http://pcpartpicker.com/part/xfx-power-supply-p1750bbef...

For the CX: http://www.techpowerup.com/reviews/Corsair/CX600M/5.htm...
For the XFX: http://www.hardwaresecrets.com/article/XFX-PRO-750-W-Po...
what i meant by slowly suffocating and reducing life-spans is ripple suppression and voltage regulation, the more stable the power delivery is the more efficient it can be utilised and so the longer the parts live with better oc potential. CX is low tier 3, the XFX is high tier 2, that just says it all
...I'm not implying that the CX line is bad, but its just not good enough to power a high-end system safely and efficiently. It's in the hard facts found out by testing by professionals . I just wouldn't trust the CX line with a high-end system that especially utilises sli...as for the money, some people say, the CX line is very good. That is indeed true, but that does not necessarily make the CX a good choice
EDIT: another slightly more detailed review of an XFX pro psu http://www.legitreviews.com/xfx-pro-series-850w-black-e... the voltage fluctuation on this is 1.5% while on the CX its 2.4% on the 12v line, that is a massive difference

That XFX Pro 750w is a very good PSU and I told him in my above post that if his budget could handle to go for it. I can remember when XFX was not considered a reliable PSU, but they got their act together and have some good solid stuff at good prices. I have always used Corsair, but there are some very good PSU's out there at a good price and I rarely even recommend them anymore. I have an AX850w in here and a TX 650w in my other Desktop. I do know that some custom Builders have been using the CX. I don't know what the parameters are on certification, but they don't just arbitrarily throw out those certifications. They do have to meet a certain standard for sure. Most builds I have seen with the CX are usually a budget mid level build anyway. Shoudn't be much of an issue. If you are running a high end card, then I would pay close attention to the PSU. Nothing less than Bronze Certified for sure. I have seen a lot of rigs fried because of a poor choice of PSU. Not pretty.
