[Richard_191]

Hi. im looking for a Psu that can fit my SFF Dell Optiplex 780, because I need a new GPU, I was wondering where I can get a psu that fits my system. (preferably Amazon) : https://www.amazon.com/gp/product/B01GUENTKC/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A27N17VOAFJ0GR

No decent upgrades are available for DELL SFF systems.

dunno if youve opened your PC before but the mobo in the optiplex line up are on the left side meaning the gpu cooler will face upward, so you cant get something decent unless you get a small form factor gpu or there will be no space for it

I have picked out the right GPU, but I'm now looking for a suitable PSU that has at least 400W s .

You won't find a decent reliable 400w PSU for that case.

ohhhh youre thinking about the low profile 750ti, that thing doesnt need any additional cables so if your powersupply is 400w or above it will work. lets just say that your CPU uses 200w(over exageration) and the hdd takes 100w (exagerated again) the max the gtx 750 needs is 60w (but i really really really dont want to recommend you getting an upgrade on this old system, if possible dont get that card for new.... the price is just.... ridiculous... (just realized that the card you picked takes 2 slots. the optiplex is reversed so it can only use 1 slot something like this https://www.amazon.com/Zotac-Video-Graphic-Cards-ZT-P10500A-10L/dp/B01M6ZF3LC/ref=sr_1_7?s=pc&ie=UTF8&qid=1480792780&sr=1-7&keywords=gtx+1050 )

That system has a proprietary power supply , there are no real upgrades for it..It's 235w.

NOPE , they won't work with the DELL.

What do you mean though? Not trying to be mean but is it because of the case or is it because of the power connecters..

If its the case , then I should be able to use it..
