i need to get a new power supply for my pc becuase the generic 450 watt one that came with the case has blown out and the ultra 500 watt Xconnect psu that i replaced it with did not supply enough power. here are my system specs

Intel prescott lga 775 3.2 ghz (not oc'd)
1 gig OCZ dual channel ddr2 (667 mhz)
one 300 gig Seagate hardrive at 7200 rpm
Asrock dual 775-880 pro motherboard
Asus nvidia geforce 6800 gt videocard
2 optical drives (one dvd burner one dvd rom)
Ultra Fan commander (fan controller)
Kingwin Aquastar water cooling (CPU and GPU cooling)
4 case fans (1-120 and 3-80's)
3 pci cards (USB Wirless and Firewire)
Xion II case (ATX formfactor)

i would really like to find a PSU that works with my system so i dont have to deal with getting a 4th one. Also i got the last one from tigerdirect.com and i will probably be getting store credit for it so i will need to find one from that site.

I did a quick newegg search for ones that have over 600 watts which should give you plenty for what you have and may have in the future.

http://www.newegg.co...N82E16817153035

That's a link with three compared side by side. All look good to me, an although TigerDirect may have credit with you, these aren't priced too badly, so I'd look into Newegg, if you can't find these on TD.

Heres a PSU calculator.

http://www.extreme.o...ucalculator.jsp

Any PSU that you buy take the rated watt's and multiply by 70% for the true rating. This is because most psu's run at 70% efficiency. They may peak at their rated wattage but they cannot steady hold that rating.

Heres a good website on PSU's.

Not to go against SRX but I did that calculator and it said I only needed a 295W PSU which is way to low for what I have (and will have in the future). If you can afford it, there is nothing wrong with getting a large power supply because as long as it stays healthy, it will last through hundreds of upgrades...in a sense.

You can also try this power supply calculator. Its a LOT more simplified that the extreme one, but it has been pretty accurate in the past.

I would go with a 550W machine, maybe from ThermalTake, Antec, or possibly Enermax.

ok well first off thanks everyone for the fast relpies. Ive been looking throught tigerdirects PSUs after i read all of your comments and tried to PSU calculators and ive found a Coolmax 550 PSU that has gotten good reviews and looks promising. Do you think this is substancial enough?

http://www.tigerdire...=719600&CatId=0

heres another one that i found, a 500 watt PSU by Ultra

http://www.tigerdire...1273338&CatId=0

Also this 550 watt Aerocool

As we stated before, you chose the 3 brands we don't recommend :blink: :whistling:

I would highly recommend the 550W Antec TruePower 2.0. I just got one, it's quiet, and it keeps everything powered. Better amperage than the Ultra Connect-X and I've never heard of Aerocool :help:

well i would look at antecs but tigerdirect.com doesnt sell them and thats where i have to buy it from, which sucks. As for aerocool, on the johnny guru site it was listed with a good rating, but besides that i have no knowledge of it, thats the only reason i posted it.

TigerDirect is as of now my least favorite. Their selection is lacking and shipping takes as long as it says it will :whistling:

I know that NewEgg has a great selection of power supplies, including Antec last time I saw.

This is what I have ( http://www.newegg.co...N82E16817103933 ) and it gets the job done quietly.

You really need to get a good brand with a system sucking alot of power although yours doesnt seem that bad as your water should be powered externally if i remember it correctly, the first one should have powered your system reasonably well. But you need a quality one or bigger numbers that top one was kinf enough to actually list its efficeincy at 65%.

Also blackpandemic 295W is actually correct.

I know that it's right it's just that's what my system NEEDS to run...I love having more than necessary and I realize that upgrades will come in the future :whistling: The other one I tried gave me 325W or something which seemed a little closer.

That looks like a winner...and at only 16dB!! Yeah I like Thermaltake...although i would go price shopping before rushing in. Make sure you find the best price. Check TigerDirect and Newegg definantly.
