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

[illya]

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 !

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 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"
And get a new 600w+ PSU for the new build.

Thanks !

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.

Great, thanks for the advice.
