gtx 1050ti on a 240w PSU

SkittishGaming · Jul 17, 2018

Hello Tom'shardware,

I am currently upgrading a HP EliteDesk 600 G1. The rocks a 500GB 7200RPM HDD. 8 GB of ddr3 RAM. And an Intel Core i5 4570 (3.2GHz).
I want to stuff an SFF gtx 1050ti into it

The PSU on this thing isn't a "low quality" unit. It's certified 80+ gold, which means that it has to be delivering at least 200w. The power consumption of the GPU peaks at 75w and the CPU peaks at 85w (84w specifically). This adds up to 160w, leaving 40w for the HDD, RAM ect....

Also the 12v rail on the PSU is 16 Amps while the card uses 75w / 12v = 6ish Amps

Before anyone tells me to simply upgrade the PSU, think twice.

Would this setup work?

P.S. In case you know about the oddball HP power connectors on the z240/600g. Then yes there are adapters for the z230/z220 desktops that can be modded into z240/600g adapters but that would require a new power supply and probably a new case aswell since sff PSU's are pretty expensive. This isn't what I want to do.

Nvidia recommends 300 watts system power PSU - https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-1050-ti/specifications

As a general rule, high quality PSU makers like Seasonic do not make low capacity PSUs.

Here is one to consider - https://www.newegg.com/Product/Product.aspx?Item=N82E16817151093

You need a good 300W PSU minimum recommended for 1050Ti.
I would not try using 240W PSU on 1050Ti.

Pre-built PCs normally have always very tight PSU designed for the PC without leaving any room for upgrades. If you plan to upgrade to stronger GPU, you will very probably need a new PSU.

1.) The PC is SFF. A full ATX PSU won't fit. This is the reason why upgrading won't really work. I would have to buy a new case, since the cooler is connected to the case instead of a backplate on the motherboard, and the motherboard uses an oddball 2*3pin and 6 pin connector.I would have to buy a new motherboard. Since Windows lincesnces are tied to motherboards, I would have to rebuy windows (it can't be transfered, it's from a company). This is way to expensive. I am asking if it would work on this specific setup.

Not necessarily. Sometimes yes, as I've seen some pre-builts running on horrible 150w units, but they run. This is a quality 240w unit.Plus upgrading on a pc like this isn't that straightforward.

Try it - Don't do any overclocking.

The gold rating is for efficiency and not quality. However you would hope if they have gone to the effort of making it meet Gold standard they have built in some reasonable safety features and used ok parts but that’s not guaranteed.

That would be a kamikaze attack on the framerate counter

Not at all true. Look at EVGA’s almost entire lineup there is something wrong with the protections. You can have good parts with poor efficiency.
And there are many cases of “fake” 80+ labels.

Also, to another comment, Seasonic, or most consumer brands, don’t make many low capacity PSUs because it cost almost the same to create a 450w PSU. But OEM psu manufacutues, like Liteon or Delta, use low capacity units yet they can be great quality.

It's certified 80+ gold, which means that it has to be delivering at least 200w

The power supply rating is for it’s max delivery. If a PSU was rated for 240w, it could deliver that no matter the efficiency. What changes is the consumption from the wall.

OP, your system will consume at most 150W while gaming. https://www.eurogamer.net/articles/digitalfoundry-2016-nvidia-geforce-gtx-1050-ti-review_2
They use OC i7, and power consumption even less than they measured due to PSU efficiency.

Reaper, I said “would hope” but my point I thought was clear. The efficiency rating is just that, it’s not a quality rating. We are actually in agreement with each other.

Well my life is a lie.

Yeah thanks, this was the answer I was looking for. The math fit, just needed to know if it was really ok

Thanks
