EVGA 9800GTX+ Power Supply question

Last response: in Graphics & Displays

I've been wanting to upgrade my vid cards from my current EVGA 8600 GTS Superclocks in SLI to newer cards. I finally found what I wanted. Here is the link for the video cards I intend to buy:

My question is about my power supply. My current power supply is this:

http://www.tigerdirect.com/applications/searchtools/ite...


Now the 9800GTX+'s System Requirements say:

"Requirements
Minimum of a 450 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 24 Amps.)
Minimum 550 Watt for SLI mode system.
(Minimum recommended power supply with +12 Volt current rating of 30 Amps.) "


Is my power supply good enough to handle these two 9800's in SLI or would I need to upgrade my power supply too?

Thanks in advance for any input!

Yep your Power supply is more than enough!, you have 2 rails, 28 amps each. if you need 24 amps for a single card, there's no question that 2 rails of 28 amp can handle 2 cards.

dude... i cant belive you just asked if that beast of a PSU is enough for a 9800GTX!!
your gonna be more than enough fine. you could run QUADsli with that thing....

i can run 2 3870s OCed on a cheapo 530W PSU with 17A on my 2 12V rails ;)

@ Belial69699: Unless the PSU is badly overrated, it'll handle those cards with ease, it even has enough 6-pin connectors.

A few off topic: What resoloution do you play in and what settings do you want/need to use?
What CPU/RAM do you have? Without a fairly potent processor you'll not see the best from such a combination.

17amps total?
How???

My PSU has 18amps on a 12v rail, and people did not recommend anything over a 4670.
17amps will barely run a single 3870...how did you get two running? O_o XD

no no no, not on a SINGLE rail. i have two 12V rails. both with 17A.
its been runnin stable for a year and recently just threw in a phenom II x3 720 OCed to 3.4GHZ

i do think it is time to upgrade the power supply though :p

My current rig:

2 EVGA 8600 GTS Superclocked in SLI
OCZ SLI-Ready Edition Dual Channel PC6400 DDR2 800MHz Memory (4gigs)
Seagate Barracuda 7200RPM 500GB SATA Hard Drive
Sound Blaster Audigy SE 7.1

Normally run WoW at 1280 x 960 in windowed mode atm. Haven't really adjust the screen resolution too much. Might go higher yet.

Although that psu looks like a total p.o.s.,if it can provide anywhere close to the amps its says it can you'll have loads of power.Assuming it doesn't blow up on you.
