i have a recently purchased "Tagan Easycon 430W" PSU,
is this powerful enough to run a 320mb 8800GTS & Athlon64 X2 4600?
ps. if it is powerful enough? whats with the split/combined switch?
i gather this is for the 12V rails, what are the implications of running either?

Any advice guys?

Your psu have 26 amps and the card pulls 26/27 amps itself so no, and i wouldnt try it out either. its a little tight i would say.

You didnt?

Are you using a 6800GT or something still?

The 8800GTS, depending on OC, can pull up to 30 amps.

My X1800XT pulls 29.3 regularly. But...that is also OC'ed. Stock, it pulls around 25


I would really recommend a 550W or more for the 8800GTS. Youre spending plenty on that card...no reason to skimp on a PSU, and blow your new card.

See if this helps...

From the article

"so the GeForce 8800 GTS 320MB can be easily powered up by a quality ATX 2.0 power supply with a wattage of 350W and higher provided that the remaining capacity of the PSU is enough to power the rest of the gaming system components. On our part, we can say that not only all versions of GeForce 8800 GTS 320MB, but also the much more voracious GeForce 8800 GTX worked without problems on our Cooler Master RS-450-ACLY that provides a combined current of 22A on the +12V rail"

last time i checked, the psu requirments listed on card cases was the entire system and not the card on its own.

my card (x1950 pro) which is said to require 30 amps is being run by my 380 watt psu (22 amps) along with all the other stuff on my pc. So im pretty damn sure, the card on its own is not pulling 30 amps from my psu.

Dudes!! Play nice :p  Here's a link to powerrequirements for GPU's and there's only two things that get close to the numbers posted here and that's a crossfired 2900xt @ 295 Watts (24.6Amps) or SLI'd 7900 GX2 @ 301 Watts (25 Amps) They could be a little ways of but I think they got it pretty well.

Yikes, such strong words coupled with such ignorance.

Your VIDEO CARD isn't pulling more than 14 amps.

So should i run my PSU in split or combined mode?

LOL! so your telling me, that a single card on its own is pulling 25-30 amps from the psu.....right :roll:

in that case i shouldnt really be able to run my system on 22amps if my card alone needs 30 now would i?

i suggest you go through the psu section of the forums and just clarify your misunderstandings.

when "your card" pulls 30 or so amps on the +12V rail, its not just the card...but all the other components that use the +12V combined that do that.

I'm not sure if I got this right so correct me if I'm wrong experts.. Split mode seems to give a little more flexibility in how many Amps certain hardware can pull per rail at a specific time. So if you have a less demanding vidcard on one rail and a bunch of drives on the other, during graphically demanding times it can pull a max of 20 Amps on one rail while your drives are left with a little less juice on the other and vice versa. Whereas if you put it all on one rail it may have more stable power but you are limited to 26 Amps across the board, which could be better for more demanding vidcards and few drives/peripherals. This is what I can make of it anyway :? but I'm by no means an expert on PSU's.

Whats the verdict then?
20A X2 or 26A combined to power 320mb 8800GTS & X2 4600+?
can i do it?
July 3, 2007 8:04:39 PM

26 amps may be cutting it close.

try combined first and see if it runs fine.

If i were you, i would also get another psu just to be safe.

Use split mode, as the most power demanding HW in your rig is your GPU. With split, youll not only have the power going to the PCI-E slot, but also, power to the 6 pin power connector to your gpu.

Just checked out your link, 320mb 8800GTS under load uses 102.6W,
according to the ratings on Tagan Easycon 430W, i have 2 12V rails MAX 312W, +3.3V & +5V MAX 180W & MAX 28W for other rails,
only thing is the link doesnt state how many amps the card requires!
I believe theres a big requirement difference between amps & wattage
July 3, 2007 10:10:06 PM

Last I heard, W=VxA, so 130w = 11A at 12V :!: :!: :!:
