Should I get a secondary dedicated PSU for the GPU?

marvelousmindff · May 7, 2018

I'm upgrading my son's Cybertron Borg-Q in phases for $ reasons. I was told I could upgrade to a GTX 970 without problems or any other alterations so I managed to snag an MSI special edition card at a good price, but it appears all of the connections for my 500W power supply are either spoken for or don't have the right connector for the GTX 970 (the old card was an MSI GT 710 and apparently didn't need a dedicated power cable). Changing out the power supply could be rather complicated (the cords are all bundled/meshed/ziptied out of the way). Should I add an additional PSU just for the MSI GTX 970? If so, what kind?

No. You should get a single good quality PSU that will run the whole system.

Dual PSU is WAY more hassle than cable management.

You really should avoid multiple PSU systems at all cost, especially for something like this.

It may seem daunting to reroute a new PSU, but its actually not all that bad.

A 500 W PSU should be able to run a 970. If you don't have the two 6-pin connectors that you need then you can usually use an adapter.
Although, most PSUs usually have at least one 6-pin connector. It might be tucked away/tied back somewhere if you can't find it.

Giroro :

If it does not have the right connector, don't use an adapter.
Get a PC with the correct connections.

Man, just grab a high quality PSU's. Using different PSU's in the same PC might end burning your MoBo or the PCIe slot. Even with the small card to sync the PSU's, it's not worth the hassle. Probably a SeaSonic S12II 620W. Can't recommend that enough.

Old School Advice: Use the right tool for the job.

That applies to psus. Use the right one. That means a psu of sufficient size for the pc power needs, that has the right connectors for the component needs. Adapters are nothing more than band-aids.
