Question Is a 300W power supply enough?

[MarkZPC]

Hello everyone,
I need a help. I've got a pc with a Lenovo motherboard, a Ryzen 5 PRO 3400G, a GTX 1650, 24GB of RAM, air cooler, an NVME, 2 HDD and a DVD RW. Is an HP 300W PSU enough powerful? I hope yes, because I don't have money to buy a new one... Another question: are there any good sata to 8-pin adapters for my GPU?
Thanks

Adapters like that are never a good idea.

And no on the adapter.

What PSU is in it now?

Is it standard ATX, or proprietary Lenovo?

it's an HP psu, the one u find in every HP Pc

I meant the PSU that was with the Lenovo motherboard.

And there are a zillion different HP systems.
Some ATX, some proprietary.

sorry...
the lenovo pc came with a 180W PSU... I took the 1650, 16 of 24 gb of ram and the hdds from another build

Right.

And trying to mate what may or may not be a proprietary Lenovo motherboard with what may or may not be a proprietary HP PSU....

Lots and lots of details needed.

(and those SATA -> 8 pin adapters are never a good idea. If you didn't get it the first or second time)

No.

Just asking about that adapter leads up to think that one or the other end of this configuration does NOT have the proper cables or required power, etc.
Either the motherboard or the PSU.

Magic smoke will escape.

strange question... if i use the old lenovo psu for the mobo only and the 300W one for the 8pin gpu cable and other things like hdds, odd...?

That is even worse.

oh... WHAT CAN I DO!?

What you do is...Don't try to make a low end office level Lenovo system into something its not.

another PSU I've got is a Tecnoware 550w that costs 25€ from amazon. Do I have to trust it?

I wouldn't trust that to power a desklamp.

 

[MarkZPC]

oh... and power supplies up to 20€ with 8pin cable?

Probably none.
And probably none that will mate with this unknown Lenovo motherboard.
