Question Hp Z200 Brand new power supply does not work on it?

[TheFangOfFire43]

So I ordered a hp z200 with a xeon x3450 in it, and it only works with the original power supply, the other one I just ordered and came in the mail is a 500w 80 plus rosewill and it doesn't work with the system, no lights or fan spin, and the power supply is on!

Potentially a DOA unit?

You have both the 4pin EPS and 24pin ATX connected to the motherboard?

Both are plugged in and ive tried a old dell 300w psu and the fans spin for less than a second and turn off, but the psu light on the old one is solid green on

Solid green just means that the unit itself is getting power.

Have you cleared the CMOS?

I've tried but I'm not sure if I did it right, there is a dedicated button on the motherboard for it
