You might consider an AMD card, as they are thermally more efficient than Nvidia, plus BIOS support for AMD is better known on this system.


This was written in 2013, but is definitely no longer the case.   Both thermal efficiency and BIOS/driver support better for Nvidia.

Betreff: M92p Tower PSU Options

I installed a 450 Watt psu now, but the problem still remains.

 

I tweaked a little bit the downclocking and found out, that the card still runs stable if I remove the downclock of the GPU, but I Still have to maintain the 80% Power Limit, otherwiese a carsh will occur.

So right now all I have to set a limit on ist the power limit, which is set to 80%, the downclocking of the GPU is not necessary it appears.

 

It appears that the PSU is sufficient, but the problem appears to be something else.

I found a 24 pin to 14 pin adapter on amazon that sells for $5.95, with Prime shipping. It is in stock when I ordered on May 13, 2016.

The shortened URL: http://goo.gl/dp6WN1

I bought a powerful and power-sucking graphics card for 3D imaging. I have a Lenovo ThinkCentre and a Lenovo ThinkServer, and knew they had 180W PSU, but it was OK. I had an old 500W PSU laying around and could easily install it. I had not realized that the Lenovo motherboard power supply connector didn't match any available PSU except Lenovo. I was upset that I could not use old PSU to upgrade. I learned on this forum about an adapter cable, and then searched amazon to see if they had one. They have several. This looks well made in the close-up photos. I thought that I might have to buy a new computer. Yay.

I purchased an adapter on EBay ( http://www.ebay.com/itm/131684733841?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT ). Amazon also sells them.

Seasonics sells a PS in this format that are about 350W but you need an adapter for the 24 pin connector. You might also need an adapter to get the necessary 4 pin connectors.

There shouldn't be any issue with the 4-pin power connector.

Re: M92p Tower PSU Options

2017-01-04, 12:15 PM

Looking to buy an i7 3rd gen pc on ebay,

ok, on the moddiy website i see the 24 pin to 14 pin connector i need.
my question is there are 2 other 4 pin connectors next to the 14 pin one,
do those need power as well? can't find anything on these.

can i use PCI express cables or will i have to use 4 pin molex to 4 pin motherboard adapters as well?
https://www.amazon.com/StarTech-com-LP4P4ADAP-Auxiliary-Power-Adapter/dp/B00066IO2O/ref=sr_1_5?ie=UTF8&qid=1483531896&sr=8-5&keywords=4+pin+molex+to+4+pin+motherboard

not sure what to do with the ones circled in green.
Thanks in advance.

Re: M92p Tower PSU Options

-> Please notice, my question regards my M92p SFF, not the Tower version, but since this is a PSU - related discussion I posted it here <-

On intention to upgrading my PC step by step, I will eventually need to upgrade the PSU.

I have purchased a 24-pin to 14-pin adapter for the mainboard power, and the PSU that I have in mind is this one ->

https://www.ebay.com/itm/Be-Quiet-TFX-Power-2-300-Watt-Gold-Netzteil/401507559614?epid=2255371547&hash=item5d7bb728be:g:RpwAAOSwz09aqoxG

I only have one but quite important question: The current (OEM) PSU, has a "P2" 4-pin connector for powering the CPU , however, this PSU has a "P4" 4-pin power connector for the CPU.

Is it unsuitable, is there a compatibility issue (meaning this PSU won't do for my M92p SFF) ?

Please help - many thanks in advance!

I reviewed the ATX power supply specification (TFX spec uses the same connectors), and the 4-pin CPU power cable is designated as "P4", and there is no 4-pin designated as "P2".   My guess, since Lenovo was already breaking the specification with the 14-pin connector, that they labeled the 14-pin as P1, and the 4-pin as P2.  

 

Just an observation, 300w isn't much of an increase over the stock 240w.  If you're going to the trouble of replacing the supply, I suggest going to a 350w supply, which is also a more popular size, at least here in the US, and the pricing will competitive.
