Hey I have a 2 fan gtx 1650 with a 6 pin connector, the GPU fits in the dell PC fine but the PSU doesnt have a 6 pin connector, did the PSU in you're video have a 6 pin connector? EDIT: reviews on that psu arent very good is there a higher quality option that'll fit the computer and work on a 6 pin connector gpu

[@eliteellis9003]

@Mxkdi bro I used the same power supply you did in this video with the same Optiplex but whenever I try to turn it on it shows a orange light flashing and I was wondering if you knew how to fix that. Please respond ASAP because it may not work.

JUST GOT A dell optiplex 9020 AND REPLACED the 290w power supply with a eva 600 w powersupply i got alot of extra cables i had to get a adapter for the mother board to the power supply tho and on the mother board there is a plug in cable tha powers the hard drive and dvd/cd rom, im using the old one for now snice the new one doesnt plyg into the mother board should i unplug it and just plug the cables into the hard drive and dvd rom drive ? it seems like this power supply wll power the hard drive and the dvd rom , right now the old cable on the mother board is powering the dvd and hard drive

[@benellim4543]

Hey dude I have an Optiplex 790 and was looking at an antec vp450p on eBay, is this the exact model of psu you’ve used here? Will I need any different power connectors or will it just plug right in? It says it’s non modular in the description, not sure if that matters or not

[@hossamahmed1959]

I have an Optiplex 9020 MT. Is it ok to upgrade it's 290w psu to a 500w psu to run a gtx 1060 ? and what adapters should i buy to run an evga mini gtx 1060 with the new power supply?

[@sonnyc3826]

this video is nice....i looked online and saw a slimline of models that can replace mine only 300 watts but still better than my 240 so hopefully that will work and Dell or this place or soembody will make a better one... 600watts is the goal

[@mxkdt]

Hi, you don't need 600w power supply and if you are using gtx 1050 video card 300w power supply should be enough. Thanks

Vinny M. Hi, I'm currently working on the DELL 990MT, and you mention the EVGA 750w, and so I was wondering if you managed to get it to fit, did you? if so did you run into any space issues? I hope to hear from you as it can really help me out to know if i can install the EBGA 650w G1+ with these dimensions, 85mm (H) x 150mm (W) x 170mm (L) thank you if you can help me out ahead of time.

get a new power supply with higher wattage(about 600w or up). but if your motherboard does not even have slots for that then obviously you need a new motherboard
