I5K and AMD 6950... is a PowerCooler 500w PSU enough ?

Hi !

I´m plannig to build a new system with this components:

Intel Core i5-2500K
ASUS P8P67 B3 Intel P67 Motherboard
6GB PC12800 DDR3 RAM - Tri Channel, 1600MHz, 6144MB (3 x 2048MB)
MSI Radeon HD 6950 Video Card - 2GB
Western Digital Caviar Black Hard Drive - 1TB, 7200RPM, 64MB, SATA 6Gbs


The thing is, I already have a case with a PowerCooler 500w PSU and a DVD-RW wich I´m planning to use.
I´m not sure if that PSU is ok for that build or if I´d need to buy another PSU.
If that´s the case... how much watts would I need ?

By the way, I´d do some overclocking to the i5.

Thanks !

  1. That PSU will not be sufficient. Save money by getting a dual-channel memory kit, since P55 only supports dual-channel, and use that money towards a 650 watt Corsair, XFX, or Antec TruePower PSU. If you think you'll crossfire later, shoot for 750 - 850 watts.
  2. 2 18A 12V rails with 485W total available on these rails would indicate the Powercolor 500w supply ( http://www.powercolor.com/us/products_power_features.asp?id=8#Specification ) will work with your system.

    According to this review:

    your 6950 will require 158W (~14A) under load.

    Your processor will require 95W (~8A). Any fans/lights would draw additional power from this rail. You'd be well within spec of the power supply.

    On the other hand, if you can do it, grab a Corsair 500W 80-plus or more supply. I'm not so sure Powercolor has that great of a reputation as a PSU producer.

    Why did you say P55?
    It´s a P67 chipset. Or I´m getting confused ?
    Has P67 tri-channel support ?

    Thanks !

    Thanks for the reply.
    I´m thinking of leaving the Power Cooler PSU to an old Athlon XP and use that as a "download server" :kaola:
    And get a new 600w+ PSU for the new build.

    Thanks !
  5. Sorry, I mis-spoke. but P67 is also a dual-channel platform.

    No problem.

    Upgrade the power and you'll have a good solid build. Power is not the place to skimp when it comes to your parts. It has everything to do with the longevity of your components.
