Hey is Power Max a good PSU? I found a 550W for $35 on ebay. I have a 400W now but would like larger and more connectors.

Is it really Power Max and not PowMax (Leadman -- weak, according to Tom's Hardware), Powerman (FSP, makers of Sparkle and PC Power & Cooling supplies), or Powertronic (also real good)?

How much power were you drawing? Tomshardware.com said that the 500W Powmax could put out about 425W.
I dont know for sure and have no real way to test it as I had sold it. I will try and pull the specks for it off the apc (they have a calc to figure out what size ups you will need)

So I do at least need a bigger psu. How does the ups help? Does it ensure a constant suply of steady power, such as it could improve performance during a brown out.

I had a 500W that recently died on me after about 9 months. It ran very well when it did, but expected it to last longer than that. I guess I got what I paid for.

I got a TTGI triple-fan 520W to replace it iwth from Directron.com. I found a $10 off coupon and got it for less than $50. It's been very nice so far...appears to be much higher quality than the POWMAX was too.

I won't not recommend that PSU, I'm just a little hesitant about taking a risk on one again.

You got it man,
little known is that voltage spikes / drops can cause memory errors that can go unseen and cause problems later, a true ups will prevent that kind of issue and will save you from other things like the brown outs (old homes that the lights dim when your whatever turns on), lightning strikes, over volts, ect.
