Should I buy a good power supply or a dedicated video card?

Hi guys,

I'm preparing a virtualization rig. I will use this computer to run virtual computers. These virtual computers will run mainstream software (mainly web browsers and photo editing softwares).

Here, at home, I have an old 500W power supply (High Power HPC-500-A12C). I don't remember exactly when I bought it. I think it was between 2010 and 2012. This power supply is not certified 80+ at all, but on the box, it's printed that it provides 80% efficiency. (Without any official certification, it worth what it worth... indeed.)

If I use this power supply on my virtualization rig, I will not need to buy a brand new power supply and I will be able to buy a Intel Xeon E3-1231 V3 and a Radeon R7-360.

If I buy a brand new power supply, I will buy a EVGA 220-G2-0550-Y1 (EVGA SuperNOVA G2 550W 80+ Gold Certified Fully-Modular) and a Xeon E3-1246 V3 (which comes with an HD 4600P IGP).

So here is my question:

For desktop computers virtualization, is it preferable to have a dedicated video card or a high fidelity power supply?

Thanks for your help.

All good quality 500W PSU could supply 500W output regardless their efficiency are. The only difference is how little they waste energy upon AC/DC conversion inside PSU.

ex: 500W PSU Bronze 80% rate may took 550W from wall to output 500W, while 500W PSU Gold 80% may took only 510W to output 500W.

You can use PSU calculator such as this https://play.google.com/store/apps/details?id=com.psudatabase.app to check if your psu give enough power to your system.

My old PSU has no certification at all... I think I'm better of with a well rated power supply (the EVGA power supply I chose has 10/10 from jonnyGURU).

Yeah, that what I though... With a well rated power supply, I will stay away from troubles.

any modular SeaSonic, EVGA, or any XFX PSU.

You mean just Seasonic and XFX, Evga has some not so good psu's out there.

What not simply stick to power supplies that jonnyGURU rated over 9.5?

I never said anything about that, I just said not all Evga psu's are good.
