PSU 390 DT Upgrade

Well... before I get crazy about the purchase... are these two power supplies compatible for the optiplex 390 DT?? 

Or I definitely need another PC...

You can verify the dimension as those may not fit into a DT form factor OptiPlex.  Also, the cost of power supply can be better well spent on a complete and newer OptiPlex.  See some example systems here  https://www.ebay.com/sch/i.html?_from=R40&_trksid=p4432023.m570.l1311&_nkw=optiplex+3050&_sacat=0

T.F.SKYWINDINTL psu has very little review and is not recommended based on scant info.  390DT stock psu Size: 17.5x 8.5x 6.5 cm.

 OP can ask this question: what is the purpose of psu upgrade? to replace a bad psu or to have more power?  DT case cannot support full height video card.  If OP intends to add a low profile video card, what is the video card spec?

@redxps630​ Well yes, to tell the truth it is for more power since the GPUs they recommend are 1050 but those need a minimum of 65w and well the psu I have is only 250w...You can imagine that this is certain death for the psu. Well anyway thanks for the response, it looks like I'll have to get a new PC that is a tower

@Chino de Oro​ well... I think I'll have to find a new PC since DT limits me to what I want to do... anyway, thanks for the response.

250w is good enough for i7-2600 gtx 1050 1x sata ssd

basic psu calculator estimate 

Load Wattage: 236 W. Never mind the “50w” limit.

Another way to word the above is "Though it's outside of Dell specs, it still works."
