Will a Corsair 650 watt PSU power my system or do I need to go higher?

NZXT Tempest Case. (FIVE 120mm fans, TWO 140mm fans & TWO 12" cathodes.)

Either a EVGA GTX 285 SSC or XFX GTX 285 Black Edition graphics card.

GIGABYTE GA-EP45-UD3P Motherboard

E8500 Proc. 3.16ghz

G.Skill 4gigs of Ram

WD Caviar Black 640gig HD

Samsung 22" widescreen


 
It's plenty.

A 140 mm fan consumes only a few watts. For example the Yate-Loon D14SL-12 claims 2W at 1400 rpm. No idea what NZXT Tempest uses but it can't be very different.

Why the Crossfire motherboard if you're buying an nVidia card? If you're sure you won't buy a second card you can save $10 or so with the GA-EP45-UD3R.

Newegg specs for the BFG GTX 285 say "575W PCI Express-compliant system power supply with a combined 12V current rating of 42A or more". You have 52A with the 650TX.

Ill look at that board, is that the only difference?

And On the card Im getting, it says it requires a minimum of 650watts... So i didnt know if that ment, it took 650 and I'd need a bigger one to power the fans..etc....
 
LOL, BFG says 575W and eVGA or XFX says 650W. These guys should be locked in a room until they agree on a number. :)

OK, if you'd rather have more room for fans and disks and so on get a 750TX or a PC Power & Cooling 750W. They would cost about $20 more.

The GA-EP45-UD3R has 3 PCI slots (the UD3P only 2). It costs $15 less. The disadvantage is that it only has one PCI-E x16 slot. That means you lose Crossfire, but you don't care with the GTX 285 anyway. You also lose the ability to add a cheap 8400GS or similar. That could be handy if you ever want to use 3 or 4 monitors. That's about it, I think.

I want to go SLI but I dont think I'd need to for a while with the GTX 285, do you? And the card is already $400... so I cant afford 2 of them now and to get an SLI mobo, it'd cost $40-50 more pluse a bigger PSU to hold two gtx 285's.....idk.
 
Last actual test I saw had the GTX 295 pulling 300W at load, so I can't imagine the GTX 285 needing more :p

As for the UD3R, I'm not so sure aevm. I agree that the layout is nice, but I just pulled up the two newegg photos side by side and the UD3R is using different capacitors. It's a bit blurry but they look like they might be rated differently. Might effect overclocking, possibly?
 
The Corsair 650TX is not modular. You are thinking of the 620HX:

Which may not be enough.

I would like to offer this modular PSU for consideration:

But, it's new and the 3 user reviews are all bad. The PROFFESIONAL reviews are good though, so maybe newegg just ran into the pallet of BFG PSUs with a forklift :p

Here we go:

That's actually a decent modular buy.
 


Your light bill may actually go down a bit, if the new PSU is more efficient than the old one. Let's say you need 300W for your parts (CPU, GPU, etc.) A typical 400W PSu would do it at 75% efficiency so you pay for 400W. A good 700W PSU would do it at 80% so you pay for 375W (80% of 375 = 75% of 400 = 300).
 
Yes and the OCZ I listed is only so good in the efficiency dept.

Pretty hard to find a decent modular at a good price. I hope BFG/newegg get's that MX thing sorted out, because that's supposed to be decent.
