280GTX and 4870X2 Owners: What PSU's are You Using (Watts)

[Bony Maloney]

I am curious to see what the lowest wattage PSU's are being used to run these cards Oh and the 12V rail also.
EDIT: If any, what adapters are you using? 4 pin to 6 pin, 6 pin to 8 pin etc. Thanks

I'm using a Tagan 700W modular with 56 Amps on the 12V+ rail.

i was using a 580w hiper psu with my 2900XT which was said to be a hungry beast with all the rest of the specs in my sig. cpu @ 1.6v so using a lot of power etc, 6 case fans all blue led 12cm ones and 4 hdd's so i must have been using a good 550w out of 580w of my old psu. but it was enough to run my 4870x2 but not powerfull enough to run it in games using full 3dclocks etc so iv gone for a tagan 700w psu now, and i have to say tho the hiper 580w blue psu was my favourite of all time in the looks wise and how awsome it did look, i have to say i like this powersupply better, bigger silent fan, cool led's nice modular design nice cable colours for different things, its great

Corsair HX520W, E6600 @ 1.4 and HD4870 at 830/1000

Are you sure that GTX260 is performing up the 280 levels? You havent updated your Crymark benchies yet

 

[Xez]

Well it is in Crysis but the only other games i play are source engine ones

ill re-run some this week

I'm hoping to get an E8400 to boost my scores even more if CPU really is a factor.

a post of mine from another thread, cpu does limit this card a lot especially in crysis etc, but just clock your cpu up a tad and it will be fine

Should have done 3.6, 3.5 and 3.4 for the X2. My E6600 wont clock any higher, dont know if its a limitation of the mobo or what, I dont think 3.4 is a limiting factor for the card anyway.

 

[CraigN]

i get a faster fps in crysis with a my old quad @ 4ghz than i do on my skulltrail with my Xeons @ 3.2ghz

FSP 700W, no idea what the rails are - sorry.

 

[Bizarre]

I was using a Corsair 620 with my 4870X2 but I had to unplug a few drives and wind my cpu OC back 600Mhz for the card to be stable:/ I've since ordered a 750 pc power & cooling unit.
