Okay, so first I'll list some basic specs.
GA-M750SLI-DS4
320Gb sata
1GB of DDR(had two but one quit working)
AMD Athlon 64 X2 Dual 4800+ 2.51 GHZ
MSI NSX8600GTS
(1) CD drive
Some off brand Power supply that I got for cheap(IIRC it's a 450W)

So I'm getting some more RAM for xmas and possibly a new cd drive(mine is kind of slow). Also awhile back my dad got me another 8600GTS, that I've been afraid to set up because of all the horror stories of PSU failure.

So, can anyone recommend a PSU(nothing to expensive) that will be able to power my rig that I can put on my xmas list? Thanks. Happy Holidays.

LOL read my thread much? http://www.totse.com/community/showthread.php?t=2180746

I just got a new 800 Watt BFG Tech, and literally just installed it. My computer runs quieter and seemingly cooler than with the 500 Watt.

haha I totally missed that. sorry bout that man, and ya that's exactly what I'm trying to steer clear of. Ill check out that psu, ty

If you want a super reliable psu I suggest you get brands such as SilverStone,PC Power & Cooling,Antec,BFG,Thermaltake. My main recommendations are SilverStone and PC Power & Cooling. They are super reliable I've used PSUs from both brands and I love them so much :D

600-750W is all your going to need, don't spend more then you have to.

Something along the lines of these.

just make sure you get a good one, and not another shitty 450w offbrand one.

and make sure it's 600+W

those are the two thigns that really matter

consider the brand seasonic
