Hey all, was looking for some advice on a last step budget build.

Parts ordered already and being shipped:
e7200 core duo
asus p5q pro
2gig gskill 800
asus radeon 4850 (single)

Old parts that i'll be using
Wd 74gig raptor
1 dvd burner
1 case fan.

Now comes the real question. I need a new power supply and I'm also on a tight budget ($50 or so) with this decision as well. The one i had in mind http://www.newegg.com/Product/Product.aspx?Item=N82E16817153023 as you see is only 430w which seems kind of low with todays hardware. Do you think i can squeak by with this psu with the parts listed above? I plan on getting another psu in the future if i decide to add another gpu but for the time being this is about all i can afford. thanks.

I put one of the 500's in my friends computer, Its a very solid PSU, granted its not an SLI PSU but for a single card that will do fine.

oh and awesome price when I got the one for my friend, they were $89+ S/H online, And I got his for $100 after tax here in town at staples.

Well im kinda leaning towards the thermaltake because i can buy it locally for around that price, but I guess my real question was, is 430 watts gonna be enough juice for the parts listed above? I don't know much about psu's but even the old 20 pin psu I'm using now is 550w and it's 5 years old. 430w seems low but it's in my budget and I can just drive down the street and get it if i wanted.

Oh and the 500w one comes with 1 6pin PCI-E and 1 6+2pin PCI-E power connectors.

I mention that because its not mentioned on the box or the websites. it just says "2 PCI-E connector"

That Thermaltake only has 18A on the +12V rail. It'll probably work, but that's cutting it close.

Well that Thermaltake really is pushing it, (I know they overstate the reqs to be on the safe side but......)
for the 4850

Quote:
–450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)


I caution you on running your psu so "theoretically" close to its limit, most don't handle it well.

Well thx guys. I guess ill have to scope out some higher wattage psu's with better 12v output as I don't want to take any chances. Damnit :(
