Dual PSU In a build

[Billy_Mays]

I'm wondering is there any danger of dual PSU in one system? One PSU is from atleast 2003 and the other is from 2011

very dangerous especially with old PSUs, just get a good single PSU.

@nerdslayer1 is correct. Using dual PSUs is not as simple as simply jumping one of them. They have to both turn on at the exact same time, because of the way inductors in a system accumulate current, so you need some kind of control board for the PSUs, so that a single switch turns both units on at the same time, which is not worth it over just buying a new PSU.

An application that uses a dual PSU setup requires a set of units that are properly equip to deal with the irregular loads that it is going to be put through. You most likely aren't going to get that in a dated 14 year old power supply.

 

As for what power supply has two 8 pin PEG connector, most quality modern 450w PSU has that. Like the Corsair CX450M for example.

 

What are you powering?

Well, you can power that on a 450w. But I'll just recommend the Seasonic G 550: https://ca.pcpartpicker.com/product/DPCwrH/seasonic-power-supply-ssr550rm
