8800GT on My new XPS 420 Quad Core Q6600 with only 375W?????

post #1 of 27
Thread Starter 
Hi,
I'm new to this site, I just wanted to bring up a question I'm looking into a new video card since my new PC only came with a ATI Radeon HD 2400, I was really interested in the EVGA GeForce 8800GT 512MB.

My Specs are Quad Core Q6600 at 2.4GHZ, 3GB RAM, 22" Flat Screen, 500GB HD, DVD-RW/Blu-Ray Player, only 375W PSU at 22AMPS. With this Dell XPS 420 with Quad Core should I have received the 425W PSU?

And most important could I run a 8800GT and everything else on my 375W, 22AMP MAX PSU safely? And does it void the warranty if I change my video card, this PC is only about 3-4 months old and I've heard you can only use a Dell PSU with these new XPS systems.

I just want a solid answer from someone who knows a lot about this, I've read that Dell PSU are very good and can handle more then what is labeled. But I am not looking to take any risks on this new PC, I appreciate your time and any solid advice would be great. Thanks in advance. (I also attached a photo of the label on my PSU on this post just let me know if I'm getting anything wrong and anything I need to know)

firstly welcome. secondly check and read the warranty and just see what your options are, cause like most to keep your warranty you will have to a get a certified technician to complete the work .. for example my macbooks hard drive broke today and to get it fixed and to keep my applecare plan i have to take it to some engineer to do what i could do myslef in like 5 mins

back to you though, with the 8800gt you should be ok at 375watts but it all comes down to weather you can replace your card with a new one

The Dell 375w psu has 30amps
The 305w has 22amps.
That's what I had in my E521
305w psu below

360w on the 12v divided by 12 = 30 amps btw

Thats not how amperage is calculated..that dell psu in that pic has dual 12v rails running at 18A each...so 36A total..12A and 12B = 2 rails.

oh I wasn't sure how to come up with AMP I saw 22A MAX so I thought that was 22 MAX AMPs. Thanks for the correction. Do you think I could run a 8800GT without any harm or problem?

could I run a 8800GT on this PSU smoothly no harm done? Even with a Quad Core Processor Q6600? This is all I need to know I want to get Gears of War Maxed on my PC, is this card a good choice?

Wrong Maximum combined wattage on the combined 12v rails divided by 12 = amps
My 305w had 18a + 18a on the 12v 264w combined 12v divided by 12 = 22amps
