Looking for a new PSU

Ok I am in the market for a new PSU. Currently I got a 300W antec unit. But I think I am going to need more juice for my new rig. It is going to be water cooled. I plan to use 4 120mm(2 Sunon 108cfm and 2 Panaflo 89 cfm), 5 80mm, and 2 92mm fans. I know I know, but I got a BIG server case. I think I am going to get an XP 2000+ when the price drop more.

What PSU should I get? I don't want to pay too much for one. I like the Enermax but I think they cost too much.

What other brand is good out there and where can I get it from?

Also what does all those rating mean?

How do you calculate what you need for your system?


Thanks

Get antec, people there like them. Get the 550W if you can put of $200

I got a decent 500W made by Leadman. The POWMAX 6100X. 220W combined and 50A on the 5V.

Got it for $72 shipped from SavingXoom.

It's a cheesy site but I've ordered 3 times and had good experiences.

My Leadman/Powmax 6100E 500W thingie arrived today and it says 180W combined. Next time I'm going PCC&C.

This says the combined on the Leadman 6100E is 250W. It seems impossible to get decent information regarding power supplies themselves or to figure out one's requirements for a supply.

Well, it was tested by Overclockers.au and they got a combined of 250W on theirs. I made a typo as I actually meant 250W.

All of the 500W POWMAXs read 180W combined but it is incorrect. Mine says this as well.

Are you going to buy a fanbus or build one? The reason I ask is if you want to keep you case from getting Really confusing and cluttered, you'll get one! I have 2 extra fans in my case (1 on the side and 1 on top to vent air) plus the HSF and the front fan and the "string-'em-together" method just looks tacky. Plus it would help you regulate all the noise those fans will be producing. Heres a good site for PSU's and remember, you get what you pay for: http://www.servercase.com/.

I got a DigiDoc 5 and I am going to do the Relay mod so that I will switch voltage when it reaches a certain temp. So I am not going to use a fanbus.

Thank for the help guys. $200 bucks for the antec, sh*t that is as much as a cpu.

Anyone know any links to PSU reviews??
