Okay, so I realise I have a problem. I ordered the eVGA 7800 GT from newegg, I believe im recieving it tomorrow along with the new case and mobo I ordered.

Video Card I ordered - http://www.newegg.com/Product/Product.asp?Item=N82E16814130247

Okay about 4 hours after I ordered it I realised that eVGA 7800 GT requires a minimum PSU of 450 W. The case I ordered is a MicroATX Aspire Case w/420W PSU.

Case I ordered - http://aspireusa.net/product.php?pid=176

I am getting this case mainly for mobility, my other case I know is way better and that case has a 420 W PSU as well but I believe is much more stable than the stock Aspire one.

My ThermalTake Case - http://www.thermaltake.com/product/Chassis/fulltower/xaser3/2000a.asp



So basically I have a few options:

1) I plug and play with the stock Aspire PSU

2) I swap the ThermalTake PSU with the Aspire one and plug my 7800 gt up to that.

3) I buy a new PSU (But where will i get a 450+ W Micro ATX size?)
 
The q-pack can run standard PSUs I believe. The stock one might work, but I would change it anyway. I say swap it out for an OCZ, Fortron, Antec or some other name brand PSU.


If you have the cash, go for it. If you don't, run the ThermalTake.
 
the eVGA box says 400W for single 7800GT, 500W for SLI ( 2 7800GT)

Thats what my eVGA box says, i'd trust it over Neweggs description.

Edit: i run a POWMAX 480W PSU with only 17amps on the +12v rail and have had no issue running my 7800GT @ 500/1.18!
 
in my opinion. make sure that your dvd drive will fit with the thermaltake psu. unless you have a lite-on or sony drive, it will be pretty tight. i used the standard aspire psu with a 6600gt, but you will need a few more watts probably. i heard a legend that the new qpacks have a "better" power supply than the one i have. mine only has 13amps on the 12v rail, but i have had it over a year. it powered - 3700 san diego, 2x512mb ram, 2x160gb hd, floppy, 6600gt, tuner card, dvd drive. if you have a new aspire power supply, and it has like 18 to 20 amps on a single 12v rail, you will be ok.
 
i just checked your link and the spex claim 30amps on the 12v rail. this is a tad optimistic, there are some very good 510 watt power supplies that dont push 30 amps. anyway, should be fine for your 7800gt.
