PSU good enough for new system?

[goomer]

Hey everyone,
I'm building a new system and am trying to salvage as much as I can from the old one to keep costs down. I was hoping top get some opinions on my PSU, and whether it was up to the task for the new configuration. The PSU is an ANTEC solution series 350w. The new system will be an ASUS A8N E mobo, a dual core opty 175, 2x512 OCZ gold gamers extreme, an x800 xl, two raptors in raid 0, two optical drives and a floppy. Please note that the opty, the raptors, the optical drives and the floppy are from the old system...in other words I've been running my old system on this for two years now...the only changes are the mobo, the memory and the vid card. Do these two changes warrant in your opinion a PSU upgrade. Pleae note I won't be oc'ing. Thanks for any help.

I would think it would work. You can try using a program called Overclockulator, which can give you a good estimate. One thing you can judge off the bat is weather your power supply is a 24 pin or a 20 pin. Most new boards require 24.

It appears the old PSU should work but it may be on the edge. It may help to run a utility that will monitor the electrical voltages. The ASUS A8N-E has the PC Probe II utility that works well. Set it to provide an alarm notification for 5% discrepancies. If the power dips below the 5% mark often, it may be useful to purchase a larger PSU.

Never rely on software to monitor voltages. Instead you should purchase a $20 DMM to test the voltages, but as you pointed out if they are over/under >5% you should consider a new psu.
