Can anyone recommend A 60-70 dollar reliable 450 -550 watt PSU for SFF computers.

James_3456 · Aug 9, 2017

I need a new power supply for my Optiplex 3020 SFF to use the GTX 1050ti https://www.amazon.com/Gigabyte-Geforce-Profile-Graphic-GV-N105TOC-4GL/dp/B06WWLWWJM/ref=sr_1_fkmr0_1?s=electronics&ie=UTF8&qid=1502235308&sr=1-1-fkmr0&keywords=gtx+1050+ti+3gb+low+profile can anyone recommend a 60-70 doolar good PSU to run this card.

Your card does not need an aux power lead.
It will run off of the pcie x16 power which is a max of 75w.
If your psu is 200w or more, I would be inclined to try it.

The psu you need is a strange size.
Check the dimensions at the rear of the case.
It might be a TFX format which might work.

Neither will fit.
Check the power capability of your psu; it should be on the label.
Here is a link as to how to remove the pou.

If you notice, the dimensions are not those of a SFF format psu, regardless of the name of your PC.

And, looking more closely, it looks like you need a single slot graphics card to fit.

Looking at the images I can find. It appears to be a TFX PSU you need.
(Example listing of existing PSU)
http://www.ebay.com/itm/Dell-Optiplex-3020-7020-9020-SFF-Power-Supply-255W-PSU-M9GW7-/332329146451?hash=item4d605c5853:g:40sAAOSwzJ5Xdpgk

Example of TFX PSU
https://www.newegg.com/Product/Product.aspx?Item=9SIA9PV4XM3799

Note: The PSU I linked does not have a PCIe power connector. I just linked it as an example of the form factor. It is certainly much higher quality than what is in the Dell. I can't find any with a PCIe connector. At least not in the search. Perhaps going through them you can find one.

Be sure to take measurements. Then look at the measurements on the listing. As I am not certain it is standard TFX. It may also require special power adapters to connect to your motherboard.

The TFX example shows 225w which is sufficient for a GTX1050ti so long as the card does not need an aux 6 pin connector. Most do not, certainly low profile versions do not.

There is another problem, the GTX1050ti you linked has a cooler that will impinge on the psu.
You need a true one slot card.
I think this might be because the motherboard is proprietary or a BTX format.

I am probably going to upgrade to a bigger case then change my psu and get a gpu will this help me.

Probably not.
This, I think is your motherboard:

It is a non standard motherboard and will not fit any modern case, the mounting holes will not line up.
Possibly you could jury rig something to go into a M=ATX case or larger.

The specs say you have a 255w psu that could handle a GTX1050ti.
But, that card, in addition to being low profile would need to be a single slot card.
I found one, a Inno3D GTX1050ti that would work nicely, but I do not know where you can buy one in the US.

Otherwise, the strongest card might be a GTX1030.
Here is the evga version:

Of course, you could buy a new lga1150 motherboard and case.
Then, your current psu would not fit so you would need a new psu also.

I am probably going to get the Gtx 1030 for now since I am a bit short on cash, and will probably upgrade my computer more next year.
