Will my current PSU be enough?

[JediK]

I change my mind every other day on what I want to order, lol. Anyways, will my current power supply which is the Enermax Whisper 431w (specs below) be enough to power this using a 24pin converter:

System:
MSI K8N Neo4 Platinum
AMD 3700+ SanDiego
Leadtek 7800GT Extreme
WD:SE 120gb 8mb
dvd drive
cd-rw drive

Power Supply Specs:
Enermax Whisper 431w
+3.3v = 38A
+5v = 44A
+12v = 20A
-5v = 2A
-12v = 1A
+5vSb = 2.2A

Hrm...I think you need more than 20 amps on the 12 volt rail. Something more along the lines of 24 amps or greater would be best.

Compare to my rig and my PSU... runs great, and the PSU stays pretty cool.

+5V 38A*
-5V 0.5A
+12V 18A
-12V 0.8A
+3.3V 28A*
+5VSB 2.0A

* +5V and +3.3V combined output: 240Watts max.
* +5V, +3.3V and +12V combined output: 380Watts max
