Ati 4850 in CF = Gigabyte Odin 550w ?

[prince10t]

Hi Guys... I just want to have your comments or ideas about my PSU if it can handle my rig with no problem

setup:

GIGABYTE Odin 550w PRO
Athlon X2 5000+ BE
MSI DKA790GX Platinum
1GB DDR2 800 Kingston x 2pcs
Western Digital WD1600AAJS x 2 (Raid 0)
ATI Radeon 4850 x 2 in CrossFire


and thats just the main components. I've also used Extreme Power Supply Calculator Lite on the web and the calculations are near exact my 550w PSU can handle. ive also check ATI recommendation CF PSU and check whether there is an existing 550w PSU that can handle 4850 in CF, and there is. Let me know if my PSU will be overly stressed so that I can just decide to CF ATI 4670 instead (planning to play most games in 1280x1024 only). I'm techie but not as techie as some of you. any Ideas, comments, suggestions will be appreciated.

At 1280x1024, a single 4850 should be sufficient. PSUs are more efficient and will run cooler and quieter (and may last longer) if not run at or near their maximum rated output.

It should work. Just for example I had an Antec Neo 550 that ran my Q6600, ATI 2900 CF, SCSI HDs, DVDROM, etc.

Visiontek recommends a minimum of 550W for HD 4850 CF. It should work.

I have a 4850 and play in 1280x1024 (using old 4800+ 939 cpu & 2gb ddr xp home) and every game flys at that res, including C&C3, STALKER, Bioshock, Grid, COD4... Even Crysis is good at high (water & physics @ medium) 25ish fps average (on the demo).

So, you sure you need 2x 4850?

EDIT: I know that wasn't what you asked, but just thought it might help (assuming you haven't bought those components yet)

Imo, if going CrossFire get a better quality PSU. Gigabyte makes good motherboards but PC Power & Cooling and Corsair (+ a few others) makes the best PSUs.

hmm, majority wins. yeah ive decided, ill go for ATI 4850 then. and I've been thinking that to have a good CF configuration, the mobo, PCIe x16 should be both x16lanes when in CF mode, otherwise it'll bottleneck. Thanks guys, I appreciate the ideas.

Right, get a 790FX motherboard for dual 16x in Crossfire. The K9A2 Platinum is good, for example.
