Psu too weak for q9550?

[demonnn]

is my cheap psu of 575 watt 25 amps on 12v enough for q9550, or do i need to get another one? my budget is tight ( $300 ) for mobo and cpu . I'm gonna get the cpu for $170


i currently have this setup:

p4 3.4 ghz 650 (85watt)
4 gb of ram ddr2 800 mhz(not upgrading)
some bad mobo atx
9600 gt ( not upgrading)
2 dvd drives
2 hdd
no fans on my case



planing to get the gigabyte ga-ep45-ud3l and q9550 and maybe some cpu cooler

the q9550 only requires 10 watt more than the p4

I'm willing to take out 1 dvd drive and 1 hdd since they are old ide.

will my psu handle these???


thanx for help!!

how accurate is this ?

everything total to 15.0 amp on 12 v

i put cpu as q6600 which requires more power

but does q9550 really run on 25amp even though the system is within psu limits??

please help

First of all, a 575 watt PSU that only has 25 amps on the 12 volt output is terrible. A 550 watt PSU should be able to put out at least 40 amps at 12 volts.

Having said that, you should not have any trouble powering your system with your 575 watt PSU.

Muuuch better.

A little overkill for your setup if you ask me, but better.

Better PSU, good choice.

Youll be fine.

Yes, indeed. Much better.

Yeah, that PSU is a good little unit. Upgrading to a quad from that puny single core P4 will be a huge improvement for you .
