[SOLVED] Corsair CX750M can't hold i7 4790K & 780 Ti playing The Witcher 3

revin · Jul 4, 2015

I've been usig the 1st version of the SS 750 Gold model, 24/7 for few years now, and it's flawless !! :toast:

As an after thought... check and make sure that the fan screen (filter, if it has one on the case) is clear and dust free.
And, if it is bottom mount, drawing external air... be sure it has clearance to draw air.

No, I bought the CX750M in September, 2015.

Running a time machine off your rig is bound to cause PSU problems...too much draw (see Back To The Future, parts 1, 2, 3)

Agh... so many feels. I guess I'm a little with everyone. An issue like this is hard to troubleshoot remotely. The CX series isn't horrible either, I agree, but there's been enough negative press about the 750 specifically that if I had to pick just one piece of hardware to replace, that 750 be the most probable culprit.

I didn't know about the low shutdown temp threshold though, and taking the side off your case is free OP. Why not give that a try then fire up Furmark/Prime95 again? That might be all there is to it.

If you can use your current PSU in another build, that's always a plus so you're not just "out money" too. As far as which PSU to buy, as long as it's 600W+, 80+ Bronze or better and made by FSP, Silverstone, Corsair, Antec, Seasonic, or EVGA with good user reviews (and professional reviews) I would buy whatever is the cheapest.

Get which ever is cheaper, I believe both use the same platform anyway.

well yes ... the AX760 OEM is Seasonic and since they have the same price (which is uncommon with Corsair ... kudos to them for that) i would recommend both, but i tend to go for the OEM without the branding

weird isn't it
using newegg for comparison but for the OP if one is cheaper than the other, then yep buy that one. (tho the Seasonic has a little rebate of 15$ at newegg )

also

AX760 WINS EDITOR'S CHOICE AT TECHPOWERUP!
“To sum up, the AX760 is a no brainer if you don't want many bells and whistles (aka digital control), but do want the best that money can buy in this category. You will invest a serious amount of money, that is for sure, but you will enjoy Corsair's support for seven years while your system is being fed by ultra-clean and stable DC outputs. As I stated many times in the past, the purchase of a PSU is an investment, so better take it very seriously. A good PSU will accompany you for many many years and will actually protect your system in case something goes horribly wrong.”

the conclusion goes for the Seasonic too ... then indeed you can't go wrong with both of them, i read Jonyguru's review too but i trust TPU own PSU reviewer cmaris does a good job too.

This works well if you have unlimited cash... not all of us are so fortunate and some of us actually like to read others experiences before taking the plunge ourselves...

Guys, I'm so glad to see so many replies. Thank you so much for help me. You guys are true help for those who are inexperienced with hardware/software.

Really, thank you so much, all of you help me with this PSU's problem.

THE_EVIL_RAPIER · Jul 4, 2015

I just RMA'd a Corsair 850w HX. finally narrowed down the problem to my PSU. I could sit on the desktop or browse the internet for hours just fine. As soon as i put any load on it i would get a high pitched squeal, like a cricket, then complete power off and restart in a couple of seconds. I ended up buying an EVGA 1000w P2. I've not had a shutdown since. I explained the symptoms in my RMA to corsair and gave a screen grab of my purchase through Newegg. They didn't question it and straight away gave me an RMA number. A friend got the new unit. lol

Tim Thrush · Jul 4, 2015

I see a lot of failed Corsair units these days. Usually it's the RM units, but it seems like their quality has fallen as a whole in the last 3 years or so. Hell, I still have a VX unit in a system somewhere around here and that thing is about 7 years old!

With that said, if my PSU was making the sound you're describing I'd get a new one. The two main things that are going to bring your computer down like you're describing is overheating and power issues. I'd recommend a different brand but after doing this long enough I really don't trust any brands anymore. I think if I was shopping for a new PSU today I'd probably get a Thermaltake toughpower grand unit (not the digital line).

All computer parts will go bad at some point, it looks like you just got one that had a manufacturing defect out of the factory.

rtwjunkie · Jul 4, 2015

Definately a problem with the PSU. You've got enough watts and amps. With that setup, Witcher 3 should not pull more than 500 wats. Mine pulls 420.

EarthDog · Jul 4, 2015

Neither. Evga supernova g2 750w.. or perhaps evga gs650w. The g2 is as good or better than those you listed AND cheaper.

hey there , "Mr genius" (lol), some people just are not as smart as you (lol) and don't have the in depth knowledge of what makes a [insert computer part here] a good quality component. People rely on hardware reviews FROM TRUSTED REVIEWERS to help them make the right choices.

There is absolutely no need to be a condescending prick, as I have seen a couple of your posts are, to members...it's also pretty obvious that you don't quite have the handle on things you think you do as far as knowledge goes. Stop being an ass.

Thermaltake? hum. only hear them about cases

Yeah. I think a PSU with 600W should be fine, right?

EarthDog · Jul 4, 2015

You can overclock the hell out of both cpu and gpu and use a QUALITY 600w psu, yes.

EVGA? Their PSU is more cheaper here. That G2 750w its 80 Plus Gold.

However, the Seasonic (on the poll) is 80 Plus Platinum.

90% efficiency?

Gold? Platinum? So many 80 Plus models... hahaha

Saru · Jul 4, 2015

I mean, if I buy a 600W, should I get Platinum? Or 700, 750W a Gold is enough? Or nothing about this with the certified 80 Plus matters?

BarbaricSoul · Jul 4, 2015

You can also look at XFX as an option as well. I have a i7 3930k OC to 4.2 with a EVGA SC GTX 780ti OC'ed to 1.25GHz that has been running on a XFX XXX edition 750 Pro ever since the 780ti was new. Absolutely zero issues, even when I had the system folding and crunching (both CPU and GPU running at absolute full load).

600 silver "would be enough"

Saru · Jul 4, 2015

So that's a good one, I think: Thermaltake ATX 650W Toughpower 80 Plus Gold TPD-0650M

BarbaricSoul · Jul 4, 2015

JonnyGURU (trusted hardware site) gave the 850 watt model of that line a 9.2 rating, so I'd say yes to the Thermaltake.

I've had the VX430 in my storage server and that thing has been rock solid! I loved the VX series while they were being made.

OP you could check slickdeals.net for any current deals on PSUs too. There's almost certainly some crazy cheap ones out there today! >Link< I see an XFX 750w for $50 after rebate. Not sure about international shipping or rebates in Brazil on some of these US-based sites though

TechPowerUp gave a 9,3 for the EVGA G2 750W ^.^

Yeah, its pretty good PSU's there...

But, I dont want corsairs anymore

OneMoar · Jul 4, 2015

meh not a fan of corsair psu's they are hit and miss have a HX750 no problems with it but I have seen plenty of CX and CM 's go up in smoke ...
either way I would spring for a 600 to 700W with at least 80+ rating,modular is also good if you care about cable management
