2 x XFX 8800GTS 320mb - min PSU Requirements

[PoDd]

Hi all,

Just bought 2 of these cards and just 'assumed' my PSU was up to the job! I havn't connected them yet, just in case. PC Components:

4 x SATA HDD
1 x IDE Optical
1 x Floppy
X-FI Pro
E6600 @ 3.5 (1.55v)
3 x 120mm case fans (Stacker 830)
Evercool VC-RF
several USB devices
Swiftech H20 120 Kit
4GB OCZ 8500 SLI

Is my Tagan 2Force 580 going to cope?

Any help appreciated,

PoDd

Perhaps a silly question, why did you get 2 8800 GTSs?

I think an 8800 GTS uses 115W, so 2 would be 230W.

for safety's sake you would want a SLi compliant 800watt or higher i think.

although you would probably run ok on the 580, but there would be some serious heat and you may bork it woth continuous use.

I was thinking that. But then I thought, it wouldn't suprise me if 2x 320mb GTS's out-performed 1x GTX, for practically the same price ... it's benchie time!

yeah, they do asasuming you can get the sli profiles working perfectly for all games which in reality just doesnt happen lol


for 2xgts's 600w is enough. a 600w seasonic or 620w corsair would power that with ease.

Thanks for replying,

I bought these 2 320mb 8800 gts's for a few reasons:

I have a setup capable of sli, it cost a fortune, so why not make use of it. And having 2 cards is cool... (not a very good reason)

2 of these should be MORE powerful than a single GTX (all things being equal, driver support, sli profiles etc etc.

The GTX is HUGE!

I got these for just a little more than the cost of a GTX.

I only game at 1680 x 1050 so don't need extra memory buffer.

I can always sell one, if i dont need the power.


So, do i need to change this PSU? Or should i give it a go? Anyone running this sort of setup on a PSU of this power or less?

FYI:

Just out of interest, got this back from Tagan:

Hello,

"Thank you for your mail.

2x8800 GTS (sli) required around 300W from the 12V. The Max.ourput Power of the +12VDC from TG582-U22 is around 432W. So it is no problem to use the Tg580-U22 for 2x8800 GTS (Sli).

For the further questions please contact us!

Best regards,

Tech Tagan"


I'm happy with that, so time for some benchin'!! Any particular score requests?
