M17x R4 - Does The 330W AC Adapter Work?

I have heard many conflicting post about the 330W PSU being a plug and play, needing to be modded, only drawing 240W if it does work, being plug and play and not working. Im confused because I currently own a 330W PSU and its only partially working. By this I mean that the computer in the bios detectes it being unknown sometimes, and with several restarts it will detect it as a 330W. If I decide to unplug it mid game or on accident, It will not detect it anymore prompting me to restart my computer several times. I decided to buy a 240W to see if the same behavior occurs. If anyone can clarify and pitch their 20 cents, it would be very helpful



Here its perfectly being detected as a 330W. But sometimes that will just become UNKOWN. I don't know if I have a defective PSU as it was listed as being brand new.

EDIT: MY 330W CHARGER WAS DEFECTIVE! I GOT ANOTHER NEW 330W CHARGER WHICH SOLVED THE UNKOWN ISSUE AND ITS PERFECTLY COMPATIBLE WITH NO ISSUES!!

 

Brand new doesnt mean functioning.

The M17x r4 is capable of pulling 200w on the MXM slot and not having issue with XM chip overclocking. This was done by joining 2 240w AC Adapters, it was shown in one of the previous R4 upgrade threads.

I spoke in the other thread stating that the 330w is useless for the 17 R1, or at least I was replying to an individual who was using the 17 R1 so I apologize if the message wasnt clear. The 17 R1 has no need for the 330w since the MXM slot isnt capable of pulling more than 115w due to EC limits that cant be altered at this time and considering the age of the laptop, will likely never be alterable. Also since the CPU cooling really isnt capable of cooling above 90+w let alone sustaining it for long periods of time then its logical that 240w is all that is needed.

 

So, I If i were to have a 3940XM Overclocked, along with the 1070, 240W is all that's needed? And if the MXM slot is capable of providing 200W, then the 1080 shouldn't be a problem then for the M17x R4 at least from my understanding?

 

Are you sure on that, what was the maximum power draw that you saw with 1070N before throttling or hitting limits ? 980M never throttled in my machine even when it was reaching to the point of getting rekt by the Blackscreen problems of the 980M PCB, 137-140W power draw on it while playing Mass Effect Andromeda garbage and the clocks were always stable (Overclocked, 1.062v). No throttling at all. Also I remember a very old post that 17x R4 has better GPU power than Ranger R1 but has a CPU hard limit, and both have a power limit unlike M18x R2 but not sure now, that was a very old post. 114W is the hard figure from what I remember when Papusan OCed his 4930MX in R1.

 

My 1070 hits a power limit of max 115W and then goes down between 90-115W under full load and keeps throttling itself on my M17x R4. Not sure how your 980 was pulling 137-140W

 

330W PSU does not need any modification on R4, it’s a plug and play accessory.

 

Then it seems like I'm possibly looking at a faulty charger then

 

Fully unlocked 980M with a full custom vBIOS will draw 200W+ in P770ZM (Desktop Haswell i7 4790K + MXM 3.0b) and P870DM chassis. And with a public custom unlocked vBIOS 980M boost clocks with Overclock and Overvolt it draws over 130W-150W with higher tessellation requirements.

The Black HP 1070 MXM GPU has a hardlimit of the 110W by it's design from what I remember while 1070N MSI is capable of 200W+ and if you unlock TDP of that HP 1070 MXM I think it might draw over 120-150W but not sure how stable the GPU will be in terms of the Hardware chipset AND MXM slot integrity, and you will be needing a custom vBIOS as well, Maxwell vBIOS hack is easier than Pascal and Turing, Nvidia blocked a lot with these new GPUs and god knows what blocks Ampere will have on Desktop.

 

Anything above 115w resulted in power throttling, I tested by reflashing the MSI 1070 one watt at a time up to 120w and it exhibited the same behavior.

Its why I gave up on the R1 and moved on to a P750ZM.

 

Even with a custom vbios, you were not able to overcome the hard limit of 115W?
