Advice on budget power supply units

Hi there,

I am unsure which PSU to go for. I plan to configure SLI/CrossFire for my new build in future.

Here are two PSU's i am interested but need advice:

600W Corsair CMPSU-600CXv2 Builder Series 600W Power Supply (PSU) ATX v2.3 80 Plus Certified
It has 2 x 6+2pin PCI-E Power connectors.

OR

550W PSU, OCZ Technology ZS Series OCZ-ZS550W-UK, 86% Eff', 80 PLUS Bronze, SLI/CrossFire, EPS 12V, Quiet Fan, ATX v2.2
This has also 2 x 6+2pin PCI-E Power connectors.

Thanks in advance,

  1. both have similar power on their 12v rail (38-40a) have solid reviews for their price points. the OCZ ZS offers a bit more efficiency but nothing major over the CX600. both are good choices for budget units.

    as for SLI/CF, unless you plan to run dual AMD 5770 or something similar in power demands, I would get a PSU with a bit more power. What video cards to you plan to purchase?
  2. For now i am going to be running HD6770 because I don't do heavy gaming but in future this may change as you know so i was thinking of getting 600W Corsair for future expansion.

    I understand that if i do consider heavy gaming in future I will have to upgrade my Graphics card or purchase another HD6770 and run them side by side :)

    Thanks & Regards,
  3. STOP!

    That CX600 makes a very annoying whine when it's plugged into the wall.

    I recommend you get a TX650

    while some people report that, the vast majority make no noise at all.
