cx 600m Upgrading to a 5700XT, but I need replacement power cables...

[BloodVyper]

Hi everyone,

Long time watcher of LTT here (7 years strong!), with my first post on the forum.

 

I have a Corsair CX600M PSU unit. My old GTX 760 broke a while back, so I took out the cable (modular unit) to reduce cable congestion whilst I had no GPU. In typical fashion, I've completely lost it however!

 

I'll be getting a new Red Devil 5700XT on Thursday, but I am having trouble confidently deciding on a replacement power cable here.

 

Does anyone have experience with this PSU? Will a 6pin to 6+8 pin Y split cable work, or do I need two separate 6 pin to 6 pin connectors?

 

Thanks in advance guys!

I've bought replacement power cables for an EVGA unit before. 

i don't think you'll need two seperate cables, but make sure that whatever cables you get are advertised or branded to match with you PSU or the series that your PSU is in. Sometimes inter-brand compatibility is and issue and sometimes not all from the same brand are compatible.

There are a couple Corsair folks on the forums that can help...

 

@Corsair Nick being the most active I think.

[LukeSavenije]

i mean... with the cost of replacement cables, i'd just get a new psu... which i would advice in general with a 5700xt, that psu and that age

[Corsair Nick]

We offer dual 6+2 PCIE cables (link below) that you can purchase through our webstore.  Let me know if you have any questions.

[BloodVyper]

Thanks guys. The PSU was only bought a year or so ago, so it should be okay for a little while yet!

 

@Corsair Nick Thanks for the link, I'll take a look!

@Corsair Nick

 

I just placed an order through the Corsair site. Do you have any idea how long shipping may take? I chose standard, rather than express.

 

Order Number is 4000126265

In all honesty I also think you really should have bought a new PSU altogether, the 5700XT is a bit power hungry and a high current video card which you're pairing with a low end old Power Supply with outdated topology... it is really not a smart pairing.

Is it hungrier and higher current than the 980 Ti? I ran one of those off a CX450M (still have it btw, it was the first PSU I ever bought and it's worked fine since about 2017 when I got it) with no issue, the CXM series is a pretty solid budget platform (I think the new CXs are a bit better though?).

Grey Label CX are worlds better than Green Label CX.

 

However one thing to note is that the Grey label CXM IS NOT the same power supply as the Grey Label CX.

 

Even the Grey Label CXM uses considerably outdated topolgy and is actually a bit of a bad pick even for budget systems for today's standards.

 

Just because it worked and to some people it never gave them any issue it doesn't change there's better stuff on the market sometimes even for the same price...

 

I'd point out @jonnyGURU for this subject as no one would be more reliable to go through the differences on the many CX/CXM units out there but I think he hasn't been around the forum as much any more.

[BloodVyper]

I did a calculation using OuterVision's wattage requirements calculator and I have a good 150W of headroom. I've run a GTX 970 on it for a short while, never had any issues.

 

I will upgrade it eventually, the deal on the 5700XT was simply too good to resist!

 

In all honesty, I'm going to end up playing Project Hospital, Rimworld and Cities Skylines on it, rather than the latest AAA titles for now. Only a 60hz 1080p monitor too, so the card shouldn't be utilized much.

Yeah I knew the green label CXs were bad, I was saying new CX > CXM, though the CXM isn't horribly horrible either. Think the CXM is bad enough that it warrants an upgrade if you already own the PSU though? 

that said, the M12II is known for being very outdated and bad but I had no issues with mine, so your point that it working =/= it's always good is true. I still have it because I haven't heard much good about them (I bought it as a nooby lad without too much research) and I haven't trusted it enough since to put it in a rig to sell, lol. 

EDIT: Also note, my CX450M is a grey label, I don't know the difference between the grey and green label CXMs.

The Green Label yes, if it was the Grey Label then no.

 

Like yours a Grey Label which is fine, but OP's a Green Label.

 

Going through an old thread here at LTT we have this explanation:

Spoiler

 

The 430, 500, and 600 watt model of the CXv3 / M models (the one with the Green logo) are DSA-III based unit from CWT. They are based on an old group regulated design. The 750w and 850w models are CWT PUQ-B which utilized DC-DC for the minor rails which will yield better voltage stability than the lower wattage counterpart. All of which are warrant for 3 years and are rated for 30C.

 

The new gray labeled 450, 550, 650 models are a custom design from CWT (essentially a cost down version of the RM 450-650) are DC-DC regulated, 40C rated, black cables, and a 5 year warranty. The 750 and 850 is still based on the same platform before but has a higher rated bridge rectifier along with all of the changes mentioned with the lower wattage models

 

Just the fact it went from Group Regulation to DC-DC already is a big plus on the matters of reliability and safety.

 

@BloodVyper Wattage alone is a meaningless factor, this is a "at your own risk" sorta thing from here.

Can you recommended any good value PSU's around the 750W range?

The TX750M usually isn't too much, and it's a damn good unit AFAIK.

You don't really need 750W, 550W should be plenty.

 

If you would like some alternative how about give us a budget and your country of origin? with tools like PCPP it's pretty easy to find a good pick.

 

The TXM (2017) stated above is a very good line up indeed.

I'm in the UK, so around £100 seems like a good balance between quality and price.

 

I do want to leave some headroom. I'm going to be moving from an i5 3570k over to a Ryzen 3000 based system over the next month or so. I'm starting off with the GPU, since I've been stuck with the integrated HD4000 for the past year or so, and the i5 still performs decently in most titles.

Oh with a budget of 100 pounds it's really easy to find high end very reliable units, this was a piece of cake [:

 

650W is enough for whatever computer you possibly wanna put together, for your reference my very power hungry i9 9900K with a TITAN V is running happy on a 650W.

 

So here are 2 perfectly comparable, on the same level of performance, reliability, low noise, safe units you can consider, it's literally pick whichever you like the looks more:

You're welcome! I've used one in a rig for a friend, and though we've already established it working for me =/= good quality, I can confirm they're damn quiet (this one drives an i7 6700K and R9 290X on a custom loop). This one has only had a single clean since December 2017 as well, and every time I've seen the rig it's running quiet af and everything is in perfect working order.

Can confirm, my X5670 at 1.45v on the vcore and 4.54Ghz (high voltage for that, but I was trying to get 4.74 stable at the time) with a Gaming X 1080 Ti at max power target pulled up to 553W in synthetic tests according to my RMi. 

That said, headroom is always nice, and I'm not one to talk on reasonable wattages. Run an RM1000i in my main rig, 1000W G3 in my folding rig (low power Xeon, a 1660 Ti, and a 1050 Ti), and the 1600W T2 that was powering that rig now awaits the unveiling of my SR-2. Oh how far I've come from the days of my actually reasonable 450W and 550W PSUs, lmao.

and for reference, what if we dropped that budget down to £50-£60?

 

I have some lovely memories, age 12 of 13 (Year 2012) when I got my first gaming PC, relating to the power supply:

 

Athlon II X3 455 triple core processor

8gb ram

GTX 570

 

and... a CiT 500 watt PSU.

 

Installed my CD of assassin's creed brotherhood, it ran just fine for an hour, before the power supply blew smoke billowing into the air around the case.

 

Luckily nothing died, but that was anxiety inducing to experience!

 

Looking back, I don't know whether I'm more disappointed in choosing a tri-core CPU or that god awful power supply...

Then we get quite limited, looking through all the available units on this price range the only thing I could recommend is a 4 pounds more expensive TX550M:

Oh look what a nice coincidence, it is the TXM we were talking earlier [:

 

Anything below this (cheaper) already gets on the "you're compromising too much" category, if you want something to last then it wouldn't be a good idea.

Ooooooof. According to a recent interview with the aforementioned Jonny Guru though, PSUs often blow on the AC side and the damage never travels over to the DC side, or something like that. Recommend watching it just to get some good general info on PSUs, I only half payed attention while at work so I should watch it through again sometime.

I'm more surprised the motherboard survived.

 

An ECS MCP78PVM... horrible, nasty, cheap POS that was!

 

I was clearly too focused on maximizing the GPU horsepower at the time, and completely cheaped out on everything else lol.

I took a look, I think meeting in the middle with the TXM650 is the sweet spot for me.

 

Thanks for the help @Princess Luna!!!
