Question on my power supply, can it handle it?

I've got this power supply.
An allied AL-A350ATX.
Its outputs are: +3.3V@28A;+5V@30A;-5V@0.3A;+12V@15A;-12V@0.8A;+5VSB@2A

I want to upgrade my video card, I'm still sticking with AGP for now, to this card.
evga-GeForce 7800 GS CO SUPERCLOCKED agp.

Now there is a problem... The minimum requirement on that video card is a 350watt power supply with a 12v current rating of 18 amps. If I'm correct, the power supply I have only produces 12v at 15amps.

What would happen if I ran this video card with the power supply I currently have? I do not run any sort of printer/scanner on this computer. I'll run down the specs. This is without my current video card, obviously. Which is an ATI Radeon 9800xt.

3.4ghz Northwood P4 HT
200gig Seagate hard drive, 7200rpm (hard drive cooler as well)
2gig of ram, 4x512, corsair twinx xms.
CDRW/DVD drive
7 case fans.
vantec pci fan card
Sound blaster audigy 2 zs (no front bay)


Now. Second question. If my power supply will not run this video card, could someone refer me to a high quality power supply that will run this and is UNDER a hundred dollars? I'm on a super tight budget.
Thanks in advance!

  1. You will likely be underpowered using the current PSU. If you want a new one that costs less than 100 bucks, check out Newegg.com. They should have at least 6-8 good, name brand PSU's in that price range. Check out the Antec, Thermaltake, OCZ, Seasonic, Silverstone, Enermax and Fortron brands, they are all worthwhile. You will need at least 500 watts just to be safe, up to 550 watts would be accetable. And you can never go too high, but you'll just be wasting money if you plop in a Kilowatt of juice.

    i have 350watts for my system before. i oced both cpu and video card, the system would freeze in 3dmark06 benchmark.

    after i got antec truepowerII 550watts, everything is fine now. it costs less than 100$ on newegg.
  3. Thanks for the replies, folks! Most of the suggestions you've given are gold, as usual.

    I -knew- when my Enermax 600watt power supply blew out ((Due to me fiddling with the red switch on the back that changes the voltage for european countries. "I wonder what this button does...")) that I shouldn't have let that repair guy put in a 350 watt power supply.. And by a brand I had never heard of.
  4. save your money, u dont need 550 freakin watts of power, Antec 480w(blue or not)/380w Truepower 2, or smart power 450w/500w, or NeoHE series, the NeoHE 430w has 48A combined 16 A on each of its 3 12v rails
  5. I would not trust even a 500W Allied power supply because Allied is made by one of the worst manufacturers, Deer. Get something reputable, such as a Fortron-Source, Antec, Seasonic, or Enermax.
