what i am wondering is will the 1000w power supply be able 2 take "2 xfx hd 5770 in C/F"

i have done a bit of diggin and found

i7 uses 270w under load
hd 5770 use 108w (216w)

Hello and welcome to the forums
Yes 1000W would be more than enough for 2 5770s

 

[coozie7]

Yes, it will handle them with ease.

Your psu won't know they are there, lol. No worries. I will be running 1 of these with a Corsair 450 watt psu and similar hardware config you have. This looks like an HTPC setup, is it?

Considering that 100% max load (using FurMark) a single HD 5770 consumes 81w (162w for two), a 1KW PSU is way more than enough.

You actually have a lot more power than is necessary.

Here are the ATI recommended power supply requirements for the new ATI Radeon HD 5770 and 5750 video cards that just became available:


450 Watt or greater power supply with one 75W 6-pin PCI Express® power connector recommended


600 Watt and two 75 watt 6-pin connectors for ATI CrossFireX™ technology in dual mode

thanks alot guys and na it my own build
i was gonna go for the 5850 but saw 2x5770 killed the 5870 and not gonna up grade for a while so yer but finding it so hard to find them all out of stock in Australia
if any1 knows where some are in stock around the AU$215 mark can u give me a yell out
and i seen in alot of forums people say should go for the 2x4890 but i want directx 11 and the HDMI to shoot the sound across to my tv speakers as well and not use my pc speakers

DX games are already out, but the good ones are still coming for most people with Stalker: pripyat being the most anticipated early realease and others coming in the new Year Like Alien vs Predator and Bioshock 2.

Can you post the link that 2x5770 killed a single 5870 ?
According to the reviews i read,2x5770 perform pretty much like a single 5870,it sometimes beats the 5870 and sometimes loses to it but the difference isn't much,so i would like to see the review that 2x5770 kill a single 5870 please
thanks

Yeah that's what I saw too, some wins some major surprising loses (lost significantly to the HD5850).

To me I would worry if it weren't for his issues with availability, and over time, the memory limitation probably will scale with the workload and not be much of an issue, but still something to be sure of with the early DX11 games/demos maybe giving some insight into the effect of limited bandwidth.
