220 watt Power Supply question

I have 2 of these power bricks for Sager NP9280 (Clevo D900F) with male output plugs. I'm looking to upgrade the GPU but hear a single 220 watt power supply wont be enough to run the GTX 680m.

#1...Is there an adapter to combine the 2 and make 440 watts?

#2...Will my notebook handle this incoming 440 wattage without causing problems on the mobo?

I'm a novice so if you know of an easier way, please let me know. If you have a link to what I need, I would greatly appreciate it.

Thanks,
Charlie

The only one I can find has the female 4 hole plug. Mine is a male 4 pin plug. Like the one below I found on ebay.

The adapter converts two chords into one. So two males into one male.

 

If I have to use the adapter, can my machine handle 440 watts incoming?

It will draw what it needs, I can't remember if it had a global power limit but I don't think so.

 

Hey Meaker, I bought a dell 330 watt PSU for cheap. How can I go about placing my clevo plug onto the 330 watt Brick? I'm decent at soldering so would it be better to crack open the brick and go that route or, just cut the old off and replace/solder with my cable?

Thanks for the help!

Charlie

 

I opened the brick and desoldered the cable from the PCB then used the cable from another PSU to replace it.

Clean and safe if done properly.

 

You could also simply buy an adapter.

 

I have the male output style on my cable. Every adapter I've seen has been for female.

 

I mean you could also just cut the wire from a PSU that fits and solder it into the other. I did the same for a friend, even tho the way PSU cables are build makes the soldering a bit tricky.

 

This

Probably what I will do since I hear those bricks are pretty hard to separate.

Charlie

 

If you do it, make sure you cut the 3rd ring short, the 2nd ring medium and the last ring long, so that if you solder it together, that it will be way easier than if you cut all rings even.

 

After seeing the wire size difference in the 330 watt Power supply versus my 220 watt supply, I'm going to find a different route. I don't think my smaller wire can carry the load.

 

It's probably because the 330W PSU has 3 layers while the other PSU has only 2, had the same "problem" on the one I made. All you have to do is to cut the 3rd layer completely off and connect layer 1 and 2. Worked like a charm, no degrade in performance, all measued with a multimeter.

1st layer ground
2nd layer power
3rd layer pin.

The pin doesn't exist in clevo systems.

 

I opened the brick, the actual wire size is literally twice the size. There are 2 black, one white and one green, mine has one black and one white. So I would just tie the small green wire in with the ground right?

I will probably do it because there isn't any other choice out there. I wish they made an adapter for people with the round 4 pin male outputs.

Charlie

 

Not sure why there are 2 ground but I'm unsure as to which cable is corresponding to which, I'd assume white is white and black is black, but I don't really know right now. I think the green wire might be the center pin, which you can ignore alltogether if that's the case, but I'm not entirely sure, maybe we can grab @bennyg and see if he knows something.

I mean you could wire them like you think they'd be (ignoring the green wire alltogether) and measure the output of your adapter with a multimeter. That way u'd be fine I think.

I wouldn't ever connect it into your notebook before measuring anyways, just to be safe.

 

The output plug on the 330 watt psu has the 4 pin female round clevo type plug with no center pin. On the circuit board where the green wire attaches, it said idpin I believe.

 

Can you maybe post pictures of the PSU and the plugs?

 

Yeah I can when I get home later.

 

The male tip is what I currently use on the 220 watt. The female is from the 330 watt. There are actually 2 white and 2 black wires that tie together onto the board with the green wire going to psid.

 

Alright gotcha, this kinda confuses me tho, it seems it should be pretty much the same as the other PSU so what exacly is the difference? The white and black ones are power and ground, the green one is to charge the battery. I thought u had a different dell adapter, that's why I thought u'd have a centerpin

 

The Dell supply has 3 terminals.

Power
Ground
Sense

Sense is used so the notebook can detect what supply is connected and its rating (based on the resistance of the line IIRC). I believe I remember people saying they tied this to ground to stop the supply from throttling (A small bias resistor was used rather than shorting it to ground I think, it's worth looking into). The main thing is to ensure it is not wired to live.

Dual cables are used for ground and power to lower cable losses due the amps involved.

 

Update on my PSU. I contacted Eurocom and they have the male adapter so that I can use my 330 watt psu. I looked everywhere on the net and couldn't find anything even remotely close to this. Thank you guys for the help! And thanks to @Eurocom Support for hooking me up with this elusive adapter cable. Below is a picture of the adapter.

Short and decent looking, should do the job nicely.
