Most likely the PSU doesn't have enough power for the hardware in the MSI system.

Post all the information on the PSU here.

How do you know you have a PSU problem, and not something else?

"so i gotta get a new atx psu?"

No, you've got to explain what you're doing & how, plus improve your troubleshooting skills. Are you 100% sure the MSI setup works? Board, CPU, RAM, video are all "known to be good"? Are you 100% sure the Dell PSU is a standard unit & not a proprietary unit? If it's a "Dell only" unit & you connected it to the MSI board, you more than likely fried the board.

Have a look at the main ATX plug. I don't know if it's a 20-pin or 24-pin, but make sure the wriring matches the following, if it doesn't, it's a "Dell only" unit & your MSI board is probably dead.

Standard 20-pin ATX pin-out

Dell 20-pin ATX pin-out

24-pin ATX12V pin-out

the dell psu wiring matches that of a 24 pin atx 12v pin out except for the 10th and 11th wire which is white and not orange.

but the thing is when i attached it to the msi mobo, the psu wont even work. like the fan in the psu wont spin.

yeah vedio card is working, ram is new, mobo is fine when i got it the only thing i dont know is if the psu is atx or propreitary.

That PSU appears to be proprietary. It is labeled by all sellers as a Dell PSU.

I asked you at the beginning to post all the information on the PSU. Is the a line with ATX and some numbers & letters after it? If so, post that.

If it is proprietary and you connected it to the MSI board you probably fried everything.

What do you have right? I am not sure if you are still trying to fire up the MSI board or what.

If the MSI motherboard, post all the hardware specs. Which MSI board, CPU, memory, graphics card,etc.

If the board is attempting to POST then it may be overheating. Did you install the heat sink/fan using a thermal pad or thermal paste?

Do you have metal standoffs in the case under each screw hole in the motherboard and ONLY in those locations?

yeah the heat sink was attached to the mobo when i bought it and yes there was thermal paste on the cpu fan.

will not placing the cpu fan evenly onto the motherboard affect anything? like, one of the clips doesnt really clip but it seems to be on pretty tight.

"one of the clips doesn't really clip but it seems to be on pretty tight".

The heat sink must be uniformly secured on all corners, so yes I would guess that is your problem.

I suggest you either wait for a member familiar with how to repair that or start a new thread.

You need to post the full model number of the MSI board. I assume it is running an Intel processor.

It doesn't matter but Intel heat sinks are the ones having problems like that. Push pins that don't hold. There are some suggested fixes but I have no personal experience so I can't comment on them.

edit

You will need to clean off all the thermal paste/pad and reapply according to Intel instructions for your CPU.

why do i have to re apply? if it works just fine with the paste they gave me when i bought it.

You may have bent one of the pins at the bottom where it goes into the hole on the motherboard. The only way to know is to remove the HS/F. This website, http://www.pcstats.com/articleview....
has instructions for removing and installing HS/F with those push pins-personally I prefer the back plate with the normal screws.
