Question Prebuild upgrade?

[spike135]

hello!

i bought a prebuilt pc from lenovo years ago, i wanted to upgrade his 210w power supply and the gpu but after i called the lenovo support they told me that the propietary motherboard can only support up to 310w psu (that i need to bought from lenovo off course) but to be honest i don't really believe them because after doing some search i found this video where a guy installed a psu from another manufacturer on a case that seems to be the same as mine (

I am really stuck with my PSU or can i upgrade it with something like a Corsair SF750 with a 24-10 pin-converter or will it blow up my computer? thanks

stuck with my PSU or can i upgrade it

the majority of these systems that i've worked on were not even worth the effort to upgrade in this fashion.

usually do to:
the case doesn't have good enough airflow for a decent graphics card,
no space for a decent graphics card,
the motherboard lacks many features that a decent retail board will have(PCIe speeds, etc),
board doesn't support faster RAM varieties,
board doesn't support more powerful CPUs,
the PSU area isn't designed to fit retail models,..

told me that the propietary motherboard can only support up to 310w psu

it's possible that it's such a cheap proprietary board that it can't properly manage more power but i would want to see one, or the connected hardware, actually damaged in this process.

The motherboard will only draw as much power as it needs from the PSU, provided you connect all the different voltage rails correctly. You could power it from a 1500W ATX PSU quite safely, although that would be ridiculous.

if you are technically inclined and can handle a soldering iron, a heatgun for the heatshrink sleeving and get all the supply rails connected with no mistakes, by all means butcher your PC and a new ATX PSU. If you don't get it right, watch out for sparks and "magic smoke".

It would be far better to sell the Lenovo for a few bucks and build a new system using standard components. You could fit any parts you like, instead of messing around with a potentially disastrous bodge which could catch fire if you get it wrong.

While upgrading your PSU in a prebuilt PC can be tricky due to proprietary connectors and form factors, it's possible to do so with caution. It's essential to ensure compatibility with your motherboard, connectors, and power requirements. Research thoroughly, check your motherboard specs, and consider consulting a professional if you're uncertain. The video you found can provide some guidance, but proceed carefully.

If you cannot buy a proprietary 24 to 10-way adapter specifically designed for your computer, I'd advise against "experimenting" unless you have a complete understanding of the techniques and risks involved. At the very least you need a reasonable knowledge of low voltage power electronics and practical wiring skills.

There are no dangerous voltages on the outside of an ATX PSU, but the 12V rail can supply tens of Amps and hundreds of Watts, which is more than enough to destroy components if you make a mistake.

Stick with what you've got and save up for a better computer. There are plenty of second hand bargains around if you don't want to buy a new computer.
