okay- I have a relatively large personal file server that has been crashing due to overheating.
it consists of the following:
generic atx 450w power supply (it was like $25 shipped at most, so its not high-quality)
tbird 1000 (I was thinking of getting a cheap 1.5v 1700+ tbred, to hopefully reduce CPU heat, would this help at all?)
ECS K7S5A 3.x (works with palominos and tbreds, notoriously picky about power supplies)
512mb sdram
intel NIC
4 maxtor 120gb 5400rpm disks
1 maxtor 40gb 5400rpm disk
1 maxtor 60gb 7200rpm disk
1 wd 120gb 7200rpm disk
1 cdrom that is virtually never used.
3 80mm case fans (32cfm each)
running voltages/temps are as follows:
core1 => 1.87v (i overvolt-modded this chip by closing a L11 bridge to give 1.85v)
Vddr => 2.48v (not really necessary, i dont use ddr in this machine)
+3.3 => 3.31v
+5.0 => 4.99v
+12 => 12.60v
core temp => 44C (111.2f), (machine crashes around 48C (118.5f))
board temp => 33C (91.4f), (room temp in the house is around 73ish f, possibly 80f very near the server)
It was all running fine (but somewhat close to the limit) in my parents basement in a cool environment. Now it is in a somewhat warmer environment, and it barely works without crashing if i have a HUGE box fan pointed at it on high. The case temp seems to be fine (air coming out of the exhaust fans in the back is near room temp), but the PS fan is kicking out some MAJOR heat (possibly overheating PS, thereby reducing its power output).
I guess what i really need to know is: do i NEED a > 400w p.s. with this system? Would a decent 400w work better than my crappy 450w?
I am looking for a cheap ($50) power supply that will work with this setup. Noise is not really an issue as long as it's not too loud (think of 7000RPM Delta Black Label fans as too loud). Here are the PS's i'm considering:
1. Antec True430 ($90 @ newegg) (damn that is expensive)
2. Sparkle 400w PS (235w combined power) ($67 @ newegg)
3. A+GPB Enterprises 400w PS (240w combined power) ($37 @ newegg) (never heard of this one, but the numbers look good, any comments?)
4. Works 430w PS (230w combined power) ($50 @ newegg) (thermal fan control)
5. A+GPB Enterprises 450w PS (260w combined power) ($60 @ newegg) (3 fans, alos see #3 comment)
6. Enlight 420w PS (220w combined power) ($55 @ newegg) (have had good experience with enlight PS's in the past)
7. Heroichi (HEC) 525w PS (??? Combined power) (80 @ newegg) (would this be better than the antec true430?)
(vote in the poll...)
and thanks for all your help!
