Heya guys, in a couple of weeks i will be upgrading my comp and wondering if my PSU can handle whats comming. Here is what will be running:

AMD X2 5400
Cosair 2gb DDR2 800
MSI K9N SLI mobo
NV 8800GTS 640mb
2x 160gb SATA HDD
DVD-RW + DVD-ROM drives
4x 80mm blue led fans
1x 120mm blue led fan
4x 12" cold cathode tubes

My current supply is a Antec True Power its 550Watts and has 30A on the 12V rail, i bought it a while back but has not let me down a single time.

Can anyone help me? shall i purchase a new one? or will this suffice?

THNX :D
 
550 should be ok for that. 450 is recommended by Nvidia for a 8800GTX, and there isnt much differene between power use of a GTX over a GTS. So it should be ok for graphics and none of the other gear is massivly huge on power.

Keep in mind that all of that will take 14 power connectors all up. So make sure you have enough for that. As the 8800GTS needs its own power.

Although this one will suffice, with that much costly gear you may want a more beefy and powerful one to run it all without worry. You may get better performance and put less pressure on your power supply if you do upgrade. But the option is yours. The 550 Antec is a great power supply which will do the job though your gear may benefit from a bigger PSU.

So, have fun with your new gear :)
 
I have used several true power-II 550 watt PSU's


I have found them to be not all that great, I found they suffered from sagging 12volt readings and that was also documented many times on websites also

they were a PSU of modest construction and rating (not rated for 50C temps)


as long as you are not looking to run an SLI configuration have a look at the Antec Trio Power 650 watt its a very high quality build and they can be found from $100.00 to $125.00 most of the time
 
With +12V@30A that's not a TruePower II - that's an original HEC built Truepower. The ratings are sufficient for a system like that, however the crossloading characteristics are probably less than ideal, and given the age of these units the capacitors have probably degraded somewhat.

All the same it would be worth a try - if it doesn't do the job you can always replace it afterwards.
 
I have to agree that 30A on the +12V rail is slightly lower than you would hope for. Although anything >28 is usually fine, but I can't confirm that with an 8800GTS. I'm on school computers so they block everything at the minute, so: how many rails are there for +12V? Is it split into 15x2 or?
