What is my Power Supply?

[DreamUnleashed]

I have a Lenovo Legion C530 (90JX0007UK). I have recently upgraded the front and back fans, and added 16GB RAM. It came with a GTX 1050 and I'd like to upgrade to a GTX 1650.

However, I don't know the watts of my PSU so I'm not sure if it will handle a GTX 1650. I can't see any labels whatsoever, and the only information I've found online is that the Power Supply ranges from 280w - 450w depending on the build - it's low either way but I'm led to believe a GTX 1650 requires less power consumption, although I could be wrong.

Any help is appreciated.

Take the PSU out of the case, it will have a label on it.

If the PSU doesn't have a spare 6pin PCI-e cable it will already not work, the 1650 needs a 6pin cable.

The two GPU's use a very similar amount of power, 75 watts. So not much change there, not enough to warrant fussing over the PSU the way I'm reading it.

It has PCI-e 6+2 cable. I'm a novice when it comes to this stuff - How do you know how much power a GPU actually uses? Looking at graphics cards online it usually comes with a 'power supply recommendation' and that's why I'm concerned.

Just remove the PSU from the case and see the label. You will definitely find the max output watt capacity. Then you have to compare 2 things. 1 is to get online specification of GTX 1650 and other is to see if your psu is 80+ silver or above. If it is 80+ then you will not need to upgrade it if it matches with online specs power requirements.

Hopefully that links works - How do I remove the PSU? I can't access the screws on the left. Again, novice here, so apologies.

This is the back if that helps

see the 4 black screws around the psu area opening. remove them 4 and it should come right out i assume. each case is made differently but it should come out after removing them four on the back of the case around the psu. Sorry if i dont make full sense im not native to english.

Thank you! I finally removed the PSU. I believe it says 280w (80 Plus Bronze).

The question now is, will it handle a GTX 1650? Probably not???

Every case differs in style. But the only thing is to remove those 4 screws. Then you have to check maunally if something removes easily. If it still resists, you should remove the components in the way of PSU for its smooth removal.

The GTX 1650 does not need an additional power connector, as stated by Brockenstein, so it receives all it's power from the PCI-Express slot, meaning it's a sub-75W GPU like your current one. While it may use a different amount of power, it's not enough to matter.

So, in a nutshell, you're saying I could upgrade to the GTX 1650 without changing the power supply?

Yes, as long as the card physically fits and you have no cooling issues, there shouldn't be any problem with a card like that. The difference in power use between those two GPUs is nearly nonexistent (both have a TDP of 75W, although this doesn't directly translate to what it uses) to where if you're not having issues now, I can't see why you would after.

I don't know what TDP exactly is, but I have used a few 'power supply calculators' and yeah there's pretty much no difference when I select the 1050 or the 1650. I only have an i5-8400, 16gb ram, 1tb hdd, and a few fans, so maybe it will be okay then.

TDP is "thermal design power" and while it doesn't directly mean the wattage ceiling the card may use (and differently companies may specify it differently), in this case both cards are pretty much the same in they use nearly the same 75W maximum the PCI-Express slot may provide. If your PC came with a GTX 1050 I'd have no reservation that a GTX 1650 would be absolutely fine with that PSU.
