I currently did some upgrades to my computer and the specs are as followed

G. Skill 4 gigs of DDR3 1600 mhz
Phenom II quad-core X4 945 3.0 Ghz
Radeon 4850 X2
Mobo is a Asus M4a78T-E
250 gig 7600 rpm Hard drive
600 watt power supply

Every now and then when I first turn it on in the morning I get a Hyper transport synch error, I hit F1 to continue and never see it again until maybe the next morning, like a cold car or somthin. I goggled that a few times and came up with its an overclocking error, but I do no overclocking "wierd" I was thinking maybe I am pushing the limits of my power supply and might need to go up. If so what do u guys think I would like to upgrade to two 5800 series sometimes in the future but not going to just for DX11 I will wait till I can get somthing that will be a peformance upgrade cause right now I can play anything maxed out and it runs great. Also I am putting in 2-4 more gigs of memory soon, and will that be to much for my power supply? Thanks in advanced people on Toms have always been great help to me...

Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts series which is a major improvement over Antec’s older psu’s like the Basiq models.

K thanks saint and johnny for the info. I never new they meant an entire system I thought they were saying at least that much, Its good to know that. So really if I wanted to go from a 4850 X2 to two 5870 or 5850, I would be okay since I have a 600 watt PSU currently and its a Coolmaster so maybe not the best PSU in the world, does it get points for having a green light? JK... But I guess it would be safe to go a little above the recommened so maybe I dont need an 800 watt and could settle for a good 700 watt. Cause from what I have read it is better to have a good 700 watt over a cheap 800 watt
 
Good place to narrow your PSU search down is:

Here's a summary of what's on the jonnyguru site with regard to 650 watt units:
