Don't ask why, I just want to know if any such adapter exists as to temporarily connect a desktop PSU (EVGA 220 GS 80+ Gold 650W) to a 350W gaming laptop in CF.

I just want to know if an adapter like this exists. I've found so many weird adapters over the years that convert laptop parts to be usable in desktops but I wanted to know if I can put my laptop into a desktop. Only complication is the PSU running the mobo without a battery

You would have to bypass the laptop"s power supply / battery. So I would guess that the answer is no. You do have the option of a docking station.

this would be very temporary. So how would I google this? Laptop to PSU docking station or something? The names of the laptop jack and PSU constantly brings up common google results that don't relate to me.

My laptop is 350W under load and idles around 90W so I don't think this monster will under/overvolt from a desktop PSU. Problem is I can't google this. I have no inklink what it might be called or if it exists

the laptop plug is failing but I'm about to transition to desktop in a few months. The laptop plug causes BSoDs and Black Screens from bad power feed with my crossfire setup. The adapter is extremely expensive since the Alienware I own is very old, so it's not worth the money at all.

Before you ask more questions, I was wondering if you guys might help search this with me? I already know I can move a laptop out of its tiny case and situate it safely in a desktop case, however I need to get it to work with a desktop PSU for a short while. If it kills my laptop it doesn't matter. The laptop is nearly 10 years old but at the moment I lack the funds for a new desktop completely. This would help me a lot if it exists. I've found 204 pin to 240 pin adapters, MXM III to PCIe x16 adapters, 2.5" to 3.5" to 5.25" adapters....cables and adapters for everything imaginable. There are inverters/converters/adapters for everything but this I don't know how to google. I don't know at all what it'd even be called.

I keep trying variations of Laptop to Desktop PSU Converter/Adapter/Inverter (since batteries in laptop function a little differently than a PSU) but I get nothing but a jumble of "How to install your new PSU" results. It's all nonsense

what if I plug the laptop adapter into the PSU? Is there an adapter for that?

My laptop adapter actually needs to be 230w at 20a or else it turns off. I managed to use several bricks that were about 33% less powerful than the one I need and my laptop would disengage the plug and draw on battery. My particular brick is $220. I've used a different one in the past that was 210w 19a and it worked without causing the battery to draw but it burned out fast and would cause black screens when both of my GPUs would crossfire under load when gaming, so that was no good either. This is also excluding its overheating issues despiting the reseating of everythign in it, new thermal paste and even at one point tried new parts from friends. For example, my processor is a T9600@2.8GHz and when I used my friend's X9100@3.067GHz the power draw crackling sound issues were present 100% of the time versus just when gaming. I had thought it was the mobo in the past but unfortunately it was the brick. The mobo is $45, the brick is $220 and can only be bought in Germany used. This is all ignoring my broken laptop lid and the keys that are falling off as well. Uhg. Just not worth it. The idea for the case would have solved the overheating but not the plug. It'd also give me a sense of stepping in the right direction by purchasing desktop parts but it looks like I will have to buy everything for a new desktop all at the same time.

My laptop is 8 years old and it's simply not worth anything at all. It was my hope to find a way to plug a PSU into my mobo but I'm sure now they don't exist since I learned that laptop batteries are DC while PSUs are AC to DC. Bypassing the battery would burn the entire motherboard and everything connected, so if an adapter did exist it'd be honking huge and very expensive anyway

I know from past experience that PC repair shops have bench top power supplies that they use when troubleshooting systems. My advice is to go to s PC repair shop that specializes in laptop repair. They may be able to advise you.

If you could expose the motherboard, the power connections are probably very similar to an ATX motherboard (but modified to fit inside a laptop). It is the same technology.

that's what I was hoping for too! I'm going to open my laptop to see the connector
