GPU Dedicated power supply

[minitt]

hiii pplzz

im in the process of making a GPU dedicated PSU. The reason is i dont want to waste 6K on a PSU.

well i managed to understand all the req.

But for safety purpose i need a digital multimeter. So is there any1 who is good at using this?????? and want

to work with me ?

im willing to Do the experiment on my own system and if it works out many of us will be benefited.

That means u can buy a cheap 600 taka Psu which will be powering ur Gpu only ( only forr gpu which has

external PCI-e power connector...regrdless of 4 pin,6 pin or 8pin.... )

Thus it can save u a whole lot of money.

And the whole thing is very simple which u can do it by urself....but u guyz have to help me to sort out the

safety issues.

[Codex]

well basically yeah.But the prob is most of us have cases that don't have that much ectra space.And about which issues do u need help?I might be capable of helping at least on electronics .

[Noob™]

what kind of digital multimeter? you can surely get some cheap ones in stadium and elsewhere..

[Codex]

Yeah!Stadium has many of em.What kind do u need?U should have tried this sooner so i wouldn't have had to waste 5K on my tt TR2-420

Well i left my pc running with my HDD and dvdrom 4m the 2nd PSU from 4:00am- to 12:24pm (the same system i am typing

on ry8 now) NO issues at all not even 4 single time.

@Wintereise well basically yeah.But the prob is most of us have cases that don't have that much ectra space

bro ppl trade off all the time....sometimes u cant have everything without lossing some...in this ase its the casing space...lolz

I need help to measure resistance between the 24/20 pin mobo ATX connector (all yellow and ground wires) and the pci-e

power connector of the GPU.

If i see that the lines are shorted or near 0 resistance i have to look 4 other ways<this is where I DUN knw wut to do.

Ne ONE have knowwledge About DIODES so that i can prevent the short circuit which mi8 occur...... but if they are not

shorted then u know

simply BINGO!!

[saadbillah]

ordinary digital multimeters shows very fluctuating result measuring resistance. sometimes it varies 50 ohms. so keeo dat in mind

[minitt]

SO wut do u suggest... analog meters? or else?

[Codex]

Analog ones aren't as reliable as the digital one.For this kind of sophisticated tasks which envolve frying yo'r gpu you need to take extra procautions.Hmm........And i can't figure out after you'r part either.Damn this is complicated stuff

[minitt]

ok the GPU is powered by 2 PSU

1.PCI-E x16 slot off the mobo

2.pci-E power connector on the gpu.

SO if u want o use 2 psu their 12V will never match each other.

so lets assume MOBO PCIE slot givving 12.02V

and the PCIe power connectori s givving 12.2 V

Eventually the 12.2 mi8 see the 12.02 as a ground wire since its lower(12.02)

But then again this is not supose to happen since there is power regulator on the gpu itself.

but i wana play safe in case and want to use diode to make sure the current flows in 1 direction. i hope it

clears now.

i applied such thing be4 but forgot how to lay down the diode.

[saadbillah]

SO wut do u suggest... analog meters? or else?

i am suggesting analog ones, i am saying that dont buy the multimeter which costs 800 - 1200 tk

I saw a PSU mod by zaid haider in tomorrows gaming forum
where he drove his pc with 2 psu shorting some pins..
u can check that also..

Yup needs membership.;

[minitt]

hmmm i have seen the mods but still it needs some tweaking.....

waiting for a damn digital multimete...

You might also need a sinking resistor to absorb the power flow through the connecting line of the power supplies.

Anyway, I can help you the DiGi Multimeters...pm me.

nice ...... ami jani na kamne kore ....... but if u r successful, plz upload pics and detailed steps of how u did the whole thing ........ ami shikte parbo .....

@<nfs>SinEater u r 4m mogbazar ry8?

[SinEater]

right..
