Dodgy PSU. Need advice.

[xxcomputernoobxx]

Hello. I am rather a newbie to this stuff so I need help.

I recently upgraded my gpu from integrated Intel HD graphics 2000 to GTX 750 ti and while it hasn't arrived yet i checked my psu. Before i ordered the new GPU i didn't pay much attention to my PSU as I didn't think it was important. But the more i scroll through the forums the more i understand the importance of it. So I wonder if my PSU was capable enough to run GTX 750 ti without any problems.

My PSU is very old. It doesn't have a clear brand name. It only says MODEL: LPK2-23E3*SATA and there is a 400W sign on it.
Here it is: https://s31.postimg.cc/rcxe3rlej/20180516_180630_2.jpg

How bad is it? Should I change it and if so, to what? I would like to buy a new CPU later this year so PSU price should be around 30-40$.

*Other Specs*

Motherboard: MSI H61M-P22 (B3)
CPU: Intel Pentium G620 2.6 GHz
RAM: 4GB of DDR3 (Dual Channel Memory)
Hard Drive: not sure but looks like SATA 500GB (with 16 mb cache)

Suggestions are welcome. Thank You.

Really gruesome. That's a low-quality PSU that's not even designed for modern PCs; the rail distribution screams something that was designed for an early generation Pentium from the late 90s. Since printing labels for each model costs valuable pennies, it looks like they did one for all their models. If yours is listed as 400W overall, then you only have 16A on the +12V rail, which means it's not a 400W power supply, but for all intents and purposes, a <200W power supply. And not likely to be a quality <200W power supply either.

I would not run *any* discrete GPU with this power supply. Or to be honest, any PC.

This is the least expensive power supply at the moment I could recommend anyone use with a clear conscience. It's an aging platform that uses group-regulation instead of generating the minor rails, but it's safe and adequate for your needs.

So according to that picture, it is 200 W unit, it MIGHT run 750ti IF it is version that does not require 6-pin connector, however I would not advise doing that. Especially if that PSU is old. Corsair CX450 is lowest thing I would advise, and it is frequently available below 40$.

GTX750ti is a 60 w card.
Your processor has a TDP of 65w.
You can probably run.
But... I think I would not.
There is no guarantee that your psu can put out the advertised 200w.
The bigger problem is not that your parts would not run.
It is the possibility of causing damage to other parts if the psu should fail under load.

If you are considering a cpu upgrade or even a subsequent graphics upgrade, buy a quality 450/550w psu.
It is hard to go wrong with a Seasonic unit.
I particularly like the focus line.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
