i am thinking about upgrading my psu around xmas time because im not sure the one have can handle my system. this is the psu i have right now...

the amps for the 12v seem kinda low for what im running which is a x800pro and a p4 3.2e. looking to spend around 100 bucks or less if i can help it.

I'd say go for the FSP550PLG-SLI or if you want to save a few dollars you can try the non-SLi version. ZZF has both of them for very good prices.

i was looking at the fortron blue storm and the 12v rails are only 15a which seems weak compared to a lot of other brands. this prescott will need more than that to achieve a good oc.

the fortron 550plg looks more promising with its 36a on the 12v line.

The fortron 500w is definately not weak, and while the fortron 550plg is stronger, it's also a lot louder. So it's a trade off.

I think you'd be surpirsed at how powerful it is, Fortron is always underating their power supplies. Plus, the cables are pre-sleeved which is a nice touch.

Agreed... while the AX500-A is sufficient for most rigs out there, Pressies are hungry critters. While you could use something good for an honest 18A on two 12v rails, you would do best with a single large 12v rail; and that Thermaltake definitely won't do it (the CPU alone would max out that single 12v overclocked).

My suggestions would be the Sparkle FSP550PLG-SLI (or FSP550-60PLG), Silverstone 560w, Etasis EPAP-560, OCZ Powerstream 520, PC P&C 510w, or the Zippy HP2-6500P or HP2-6460P or PSL-6701P.

The Zippy 460w as well as the Sparkle 550w can be found lower than $100, while the Zippy 700w is the most expensive single 12v PS2 size unit that I know of. 45A @ 12v though ;)

My SmartPower 2.0 500W PSU has a 17A and 19A rails but combined they're a decent 25.83A, pushing a respectable 310W on the +12V line and ALL combined will be less. I'm not liking this Dual Rail crap anymore, I think I'll shell out on another PowerStream or that PC P&C 470 after X-mas.

yeah ive heard that a single rail is always better than a dualie for efficency purposes. i think i might follow your leed and get a ocz powerstream after xmas just to be safe.

That fortron 550w plg does have 36 amps on a single big rail.

i am impressed with this psu's 12v rail, however you have to add in the cost of of 20pin-24pin converter which to make it work with a regular single chip board. does the retail version of this include this because the oem doesn't?
