Lenovo H30-50 Power Supply for Graphics Card

Hi Lenovo,


I've recently been trying to upgrade my H30-50s graphics card. In fact, I've bought the wrong card twice from misguided advice. Ended up buying 2 cards that were 12cm instead of the needed 7cm or so. Believe me, that's been frustrating enough.


Anyway, I've finally found a card that'll fit. It's MSI's low profile 750ti. Its got plenty of power. Looks great. Hopefully should fit. Here's the link:


Wattage on Amazon says 400W. Wattage on Nvidia website says 300W. As far as I'm aware, the H30-50 has a 240W PSU? Is this graphics card an absolute no-go?


I have the i3-4160 model. 12gb ram, upgraded with 8gb recently. 1TB HDD. 


If this is not a possibility, is it possible to upgrade the PSU considering how slimline these pcs are? I'd much rather find a new PSU than have to try and find another, decent specification, low profile graphics card.


Any ideas?

Re: Lenovo H30-50 Power Supply for Graphics Card

(My old Lenovo ID wouldn't recover for some reason. I've given up and started another on a new email.)

I read through said topic. I saw that the person in question said the 240W PSU, which I have, would be sufficient for the Gigabyte 750Ti low profile. So, I purchased it.

Link to the product:

After getting it, I plugged it in and got black screened. After trying a few fixes, I've come to conclude that it's likely a power problem. Everything still boots and works after the 750ti is removed.

I've also ran in safe mode & similar to see if it's a conflicting driver error. Doesn't seem to be the case. Only problem I can't rule out is a: the card is faulty or b: the PSU isn't enough.

Any ideas?

Lenovo supply 2 PSU for the H30, 180W and 240W.  I think the 240W is only for the i7 so you'll probably have the 180W PSU which will not be enough to power the GTX750.  


Check your PSU model number against Lenovo H30 hardware options in the manual


I've copied the details for you. 


Liteon PS-3181-02 VG 180w
Huntkey HK280-71FP 180w
Liteon PS-4241-02VG 240w
Huntkey HK340-72FP 240w
FSP240-40SBV 240W
Acbel PCB020-EL1G 240w
Liteon PS-4241-01VB 240w
