How Much Power Do I Need?

post #1 of 9
Thread Starter 
Im guessing a 400w would be more than enough, but how much room would that leave for overclocking?

I plan on using these specs:

Q9550
GTS 450
4GB DDR2 800mhz 2x2GB
500GB 7200RPM HDD
Zalman heatsink

edit:

Anyone know of a better/cheaper/same price as this PSU?

Thermaltake TR2 W0379RU 500W - $55/35 after MIR.
  • 1 x 6-Pin, 1 x 6+2-Pin
  • 5 year warranty
Anyone know how reliable this PSU is? Thermaltake from what I know is a solid company and it seems to have decent reviews.

400w is pretty much exactly if not a little bit less. but you should get 600-750w in case of future expansion.

It's a piece of crap in comparison to this:
http://www.newegg.com/Product/Produc...k=antec%20400w



Here's the thing with Thermaltake's PSUs. The Toughpower line is great. The TR2 / PurePower line, however... They take decent units from CWT and send them to reviewers where they get good reviews. Then they take crappy overrated HEC units and give them similar names, and pack Microcenter and Best Buy's shelves full of them.

Yeah, thats why I was going by reviews. Thermaltake is usually the lowest on my list of PSUs.

I saw that Antec NEO one too, but what I wonder is how much room I have for overclocking. 400w should be enough considering it would be running a GTS 450.

The cheapness in me says that the 500w Thermaltake with its 1 6pin + 6pin+1 would be better, but the even cheaper side of me is saying "by the time you get another GPU, you can buy a better PSU"

So you can see Im kind of torn, but I think Im leaning towards the NEO.

400w is enough but the Neo ECO 520 is only $5 more, so I'd jump on that deal. That PSU will handle any single GPU upgrades you'll make.

You would have more than enough headroom for overclocking with the 400w though. Your max stock power consumption would only be around 200-250w.

Yeah, I just saw your thread. I think I may get that instead.
