Dual PSU

[Dee]

Well, many of us have lighting, fan and other blings in our chassis and in most cases we power them by the one and only PSU [assuming we have a low grade PSU, indeed some of us do ]. So if you have many 80mm, 120mm or 200mm fans and multiple LEDs to connect to your PSU and worrying about power consumption, I have a solution, a simple paperclip trick that allows you to use a secondary PSU without connecting the 20pin plug to the motherboard.

All you need:
*1 ATX Power Supply
*1 metal paperclip [or gem clip]
*Pliers or any other thing for cutting the clip into two halves.

So, here, follow the steps, very easy.

Step 1. Cut the paperclip into two halves and bend, you will get one half like this:


Step 2. Find out the two holes you will plug this pin into. You can find these beside the plastic lock that holds the plug with the female. Find the green wire and beside it a black ground wire. Here I skipped the middle hole between these two.


Step 3. Push the two ends of the paperclip into these holes so that they don't come out.


Then you will have something that looks like this:


You are done!

Now where to put this?
I have a mid-tower case and it's almost impossible to find enough room to put a whole PSU. So I did put that into the Optical Drive bays. It took two bays and fits exactly into them. All I had to do is to bend the four small metal holders outside the cage using a flat head screwdriver and pliers.

Then connect the power supply using a power cable. What I did is I cut a circular hole in the PCI covers and inserted a cable through that.

Nicely demonstrated but the all of the pictures except the last one is out of focus.

My phone's no backlight. That's why. I'll change the pics soon.

@Rakin , if y6u have done the same thing as described, there is no need to solder, just put some tape around that. And if it's loose then get a soldering iron and some solder and pull out the job.

duita PSU ekshathe... kemon jani hasshokor shunai

এটা হাসার কোনো ব্যাপার না। আমার কেসিং এ ২টা ১২০মিমি এবং ২টা ৮০মিমি ফ্যান লাগানো আছে, এবং দুর্ভাগ্যবশত আমার পাওয়ার সাপ্লাই ডিলাক্স ৪০০ওয়াট। এজন্য আমি আমার আগের পিসির পাওয়ার সাপ্লাইটা এটায় লাগিয়ে দিয়েছি। মানুষ হাসলো না কান্না করলো সেটা আমার ব্যাপার না, আমার দরকার পারফরম্যান্স। অনেক মানুষ ওয়াটার কুলিং, লিকুইড নাইট্রোজেন, এইসব শুনলে হাসাহাসি করে, কিন্ত আসল ব্যাপার পারফরম্যান্স, দেখতে কেমন, শুনতে কেমন, সেটা ব্যাপার না।

LN2 ar WATER COOLING niye ami kono hashahashi kori na...
kintu koshto koire arekta notun PSU kinlei hoy...
GOOD THING amar 750W
naile amar kandar lagto... 3 ta 80mm ar ekta 200mm
BTW... duita PSU hoile je performance barbe ta kintu na...

Whats so funny here? There are full tower cases out there offering 2 PSU bays, and they exist for good reason.

kintu koshto koire arekta notun PSU kinlei hoy...

Whats the maximum wattage you can get from a PSU? 1600W as of now? But 4+ overclocked GPU workstations with highly overclocked CPUs need way more than that, and those are for enthusiasts, not for business. In those cases, more than one PSU is a must. Now the point is, as a consumer level user, you can do the same to fuse the abilities of 2 low power PSUs to form a fairly powerful PSU (say 400+400 = 800). This way, you are saving the money that would've otherwise been spent on a more powerful PSU.

That made me LOL. Correct me if I'm wrong, but even with current technology the gfx card does not scale well. So, you'd be thinking if you hook up 4 gfx in CF/SLI you'll get 4 times the performance of a single card? Wrong. Though the drivers are improving. I'm speaking from experience. I had two HD 3870 X2 in CF (essentially 4 GPUs, 2 GPU per card). The second one died about two months ago. But I didn't notice "that much" of a performance decrease from using only one HD 3870 X2. But currently using HD 5870. However, I've read that Nvidia cards scale well in comparison to ATI cards.

I use a Thermaltake 750W PSU and for three years its been going strong! Overclocked my E6850 from 3GHz to 3.73GHz and overclocked the 3870 X2's when I had em. Never ran into problems with PSU not giving enough power.

Anyway, heard about dual CPUs/quad GPUs and what not. But dual PSUs are a bit unconventional. Leave it to us Bangladeshi gamers for coming up with unique solutions! FTW

but if u use 2 480gtx and overclocked processor and the whole pc is watercooled then u would need dual psu afaik...

duh... nope... :closedeyes:

ok then..use 1600 watt psu...
and what dee did was very good.buying a 750 watt for this kind of pc is waste of money...the cleaver thing to do is buying a branded 400 watt psu for pc and a non-branded psu for lightning....

dui psu, its not essential... I told 'em a bit ago...

প্রটন চেইন ভাই আপনাকে অনেক ভাল ভাবে বুঝিয়ে দিয়েছে কেন দুইটা পিএসইউ দরকার। এখনও যদি বলেন যে এটার কোন দরকার নাই, তাহলে আমার আর কি বলার আছে...
আর আমি কেন দুইটা পিএসইউ ব্যবহার করি সেটা একদম প্রথম পোস্টে লেখা আছে, আশা করি আপনার বুঝতে কোন অসুবিধা হয়নি।

kintu ekjon ke na chine... Kono bepare kotha bolao to thik na...

কিন্তু আপনার যেই পোস্টে তানভীর উত্তর দিয়েছে, সেই পোস্ট দেখে তো আমারও তাই মনে হয়েছে। :s

Yea, you got it right, that's what I did.

ভাই, আপনি বাজারে যেই জেনেরিক পাওয়ার সাপ্লাই গুলো পাওয়া যায়, সেগুলোর ব্যাপারে মনে হয় জানেন না। সেগুলোতে এমনিই একচুয়াল ৪০০ওয়াট থাকে না, তার উপর যদি আমার ২টা ১২০মিমি [আরো দুইটা লাগানোর স্লট খালি আছে] আর ২টা ৮০মিমি [এটারও দুইটা স্লট খালি আছে] আর অনেকগুলো এল.ই.ডি থাকে, তাহলে ডুয়েল পাওয়ার সাপ্লাই সেখানে অনেক হেল্প করে। আমি সিঙ্গেল, ডুয়েল দুইভাবেই ব্যবহার করেছি, সেইজন্য আমি জানি যে ব্যাপারটা কি।

yes u wud...try to read sum reviews abt 480gtx u wud need 2 psu's at least...

2 480gtx needs 1000watt psu...Say you have a 480 and a 600W PSU and decided on going for two 480's in SLI. Instead of upgrading to a 1000W PSU, you could just buy another 600W PSU

yep.... you can spend the money on upgrading your pc

I guess u dont know much about high-end PCs.... and their power consumption

That made me LOL as well. This solution is not only used by us, its internationally used as in enthusiast grade workstations, more than 1 PSU is often needed. Who complained about multi GPU scaling? And when did someone start talking about "gaming" high end PCs? In CUDA based workstation applications, scaling is way better than games. And nobody is questioning the pros or cons of installing them, the topic here is the need of "2 PSUs"

[aayman]

Actually ai guide ta amar kaj e ashte pare. Recently chinta kore dekhtesi koyek months por 460 SLI korbo naki. Amar kase akta partially noshto TR2550W PSU ase jeta full load e prob kore but 1 GPU should not be a problem at all. Purapurai sure na though as new MOBO lagbe.

aikhane o 2 ta thermaltake ba corsair psu aksathe connect kortese na ...... so u r actually not understanding the main point.

Delux is a cheap branded psu intended for normal use. Their ratings may show 400W but actually i doubt it is even 250W. Plus inefficiency to asei. Not like the usual minimum 70% or 80% plus efficiency of thermaltakes or other branded psu.

Also matters more is the power ratings on different voltage rails which generic psu suffer more, especially in 12V+ rails. Ulta generic psu te dekha jai 5V+ e current beshi instead of 12V+.

So aikhane o 2 ta 400W + 400W= 800W pacche na. Actually aikhane Delux 400W + Delux 400W= roughly Thermatake 400W ....... taio doubtful ...... but given his budget, it is a good solution .....
