Changing thinkcentre m81 PSU replacement question

[mutazoid]

This is the model of PSU Im trying to replace.

Ive never changed a PSU so I dont know how to find out if will get the appropriate.  I was thinking of bring it to CanadaComputers and see what they say.

 

Do you think this will be possible?

Thanks for any tips.

Why do you want to change the PSU? It's a non standard PSU, so you'll be wasting your time by going to the store.

thats what I was thinking....

Id love to upgrade the GPU so I can play some rocket league   and work on a 4k monitor.

What's the exact configuration of your computer?

model , cpu, ram size etc

 

A 230w psu is good enough for a RX 460, RX 550, RX 560 , GTX 1050, 1050ti, 1650 ... all these consume less than 100w

You would have to improvise a bit if you need a 6pin pci-e connector ... what you could do is to get a 2xmolex or 2xsata to 6+2 pci-e adapter cable , cut the molex/sata connectors and solder (or twist the wires) to the existing 12v and ground wires (yellow and brown on the ebay psu is 12v, black is ground)

 

Alternatively, you'd have to buy another motherboard and move everything (cpu,ram) in it and that would allow you to use regular atx power supplies.

depending on cpu you have you may be able to find a motherboard for less than 30$

I through in a Sapphire Radeon HD 3650 with 512 mb of ram and it works fine at 1650x1050 but craps out when dropping out to play rocket league...  Does this card actually draw more power than a gtx 1050?  Im starting to think there is a problem with the PSU.  (This PC might just go to my father   )

It's not about power consumption, it's about the capabilities of the gpu chip on the video card and the limited amount of video card memory on the card.

Simply put, the 6350 is not as smart as more modern cards like RX4xx , RX 5xx, GTX 1050 or higher. 

 

AMD 6350 is a rebranded AMD 5450, and has only 80 "cores" running at 600 Mhz with memory running at 800Mhz (/2 for real freq), and supports  OpenGL 4.4 and Shader Model 5.0. The whole board consumes around 20 watts

In comparison, RX 460 has "896" cores running at up to 1200 Mhz, with memory running at 6500-7000 Mhz (/4 for real freq.) and supports Vulkan, OpenGL 4.6 and Shader Model 6.4 ... all this for around 60 watts (3x the power)

GTX 1050 has "768" cores, running at up to 1500 Mhz with memory running at same 6500-7000 Mhz (/4 for real freq.) and supports the same things or newer for less than 75w

 

So if a video game heavily optimizes everything for Shader Model 6 or higher, the RX card will obviously work way better.
