Does this power supply have enough power to power a GTX 750Ti ?

izzyfast · Oct 28, 2016

Okay, so my current PC is a really frickin' bad one in my opinion, it's the Lenovo H50-55 and I was wondering (since my current GPU is kinda "broken" the GT730) and I was wondering if my PSU could barely run a GTX 750Ti.

Here's a picture of the PSU (Remember I DID NOT build this PC it's a prebuilt so don't ask me why this is the PSU I have)

I have no option to simply replace the PSU because of Lenovo's stupid choice to have an 14 pin connector on the motherboard.
The last option would be to A. Replace the motherboard, PSU and GPU B. To just simply buy/build a new PC (Which I think is the smarter choice)

Im not sure that 14-pin mobo can power a 750 Ti because the 750 Ti gets all its power from the motherboard..

Honestly, upgrade that PSU. Upon observing the side, I figured out that it can only push 270w, which is not enough. Go for a high quality 430w or a EVGA 500w PSU. Good luck!

Just buy a new PC. I don't think that power supply could handle a GTX750Ti.

Hi there,

If you purchase a GTX 750 Ti which does not require a 6-pin PCIe power cable, you should be fine with your H50-55. The GPU gets it power from the PCIe slot.

I found a nice article which upgrades off-the-shelf OEM desktops with GTX 750 Ti's with much success, even on a 250W power supply:
https://www.pcper.com/reviews/Graphics-Cards/Upgrade-Story-Can-GTX-750-Ti-Convert-OEMs-PCs-Gaming-PCs

I myself upgraded a vanilla ASUS M11AD w/ GT 620 with a GTX 750 without any problem with it's original power supply. Same thing with a Dell Inspiron 3847.

Both PC's now have upgraded PSUs. The Dell currently has a R7 370 and the ASUS a RX 480!

Good luck!

Well this particular PC has a rated 260W so in reality probably can't do 200W stable. And the mobo is 14-pin, so not much power is flowing through to the 750 Ti

All Lenovo systems have a 14 pin connector MOBO connector tho (That I'm aware of)

A regular GTX 750 draws 55W and a GTX 750 Ti draws 60W (a GT 730 draws 23W-50W depending on the version). That leaves about 200W for the CPU and HDD. I think he should be okay but a PSU upgrade should be done down the road with a 24-14 pin motherboard adapter, just to be sure.

um, doesn't the RAM/SSD also require power ?

Note that by "broken" I mean that the fan doesn't work so I can't really play games at all
