i have had this antec true power 550 for almost a year now and up until last week had rock solid rails at 5-5.04v and 12-12.1v (read by a voltmeter)

then about a week ago i noticed that motherboard monitor indicated the 5v started dropping to 4.84-4.87v most of the time and sometimes down to 4.62v....

so i checked the 5v rail with a voltmeter and sure enough it's hovering around 4.87v...

should i adjust the 5v pot to give it more juice? should i RMA the psu?


the system it's powering does require a lot of juice:

DUAL Mobile Bart 2600+'s at 2.415 Ghz @1.73-9V
4x 512mb Crucial ECC, Reg PC2100
2x WD Raptors 36gb RAID-0 w/promise S150 TX2+
2x 160gb IBM 7k250 PATA
8x NEC +/- DVDRW
52x Asus CDRW
I.O. zip100
Mits. floppy
Linksys 10/100
5.1 S.Blaster Live
Winfast TV2000XP
9700pro@335/650
4-45cfm panaflos on sunbeam rheostat
2 80mm adjustable speed enermax fans

[AMD-Me]

The pot might have been just knocked, adjust the pot and call it a day, thats the beuty of the antec 550

it's such a pain to do this...but i guess the prudent thing to do would be to increase the 5v pot first and see if all is well

i wonder if it's possible when i last air dusted the psu, that i accidently lowered the 5v pot?

in any case, if raising the pot doesn't work, i will put the fortron 530 psu i have in their and see if the 5v goes back up...

if they weren't $200, i would get a pc power and cooling 510 watter...

the antec tp 550 has no internal adjustable pots to adjust the voltage...
