PSU question

why would switching out my Power Supply from the 500 watt no-name brand that came w/ my case to a BFG ES series 800 Watt make me able to increase the core speed of my cpu past its previous limit w/o touching any other variable?

My computer is:
AMD: Athlon 64 X2 5200+
Mobo: Gigabyte M57SLI-S4 v.2
RAM: 4GB Mushkin DDR2 PC2-6400
OS: Vista 64bit SP2
VC: EVGA 8800 GTS 320MB

  1. It's called CLEAN power.
  2. thanx for the replies, but i still don't fully understand
  3. Take a look at this thread, the OP posted OCCT graphs with his cheap PSU. Then notice the graphs after that. I'm sure the CPU doesn't like that voltage jumping around (in the cheap PSU) that much. Hence clean power.
  4. thanx man, that actually helped some
  5. @ arges86, Probably the simplest explanation is your hardware combination with the graphics card being a major contender, required more solid power than the 500W no name brand was delivering.

    If your GPU was lower quality card you may have had enough power with the old P/S, but since it requires a certain amount its own self to properly run, your system was like getting its needed power through a crimped hose, using a water hose for an example.

    Now all your components have more power available than they actually need to function so they are able to draw all the power they need, and deliver to you all their capabilities they didn't have available when their power was limited.

    BFG being a graphics card manufacturer knows full well the requirements necessary to power the GPU and you made a good P/S choice when you decided to go with their P/S line.

    I hope that makes some kind of sense to you.
  6. it does

  8. Here's an old article (don't mind the references to the HIGH voltages) that might be of some interest:
