Another "How many watts" thread

post #1 of 14
Thread Starter 
Here's the system I'll be running:
4xSeagate Barracuda 500GB SATA-300
2xEvga 9800 GTX Superclocked
E8500 Processor
Evga 780i nforce motherboard
OCZ Reaper HPC PC9200 4X1024mb

Also, planning on watercooling, so overclocking will be a definite thing.
Wondering if a 600W will suffice, or if I'll have to bump to a 800W.
Thanks.

A good 600W would be fine. A Corsair tx650 is one of the better PSUs in this range and can be had for a good price here: http://www.buy.com/prod/corsair-tx-6...206178324.html

edit: The 9800GTX needs 2 6-pin doesn't it? I'll have a look around for a good PSU ~650W that has 4 PEG connectors.

I looked it up and it does . There is only one 650W that I know about that is any good with 4 PEG and that is the Xigamtek 650: http://www.newegg.com/Product/Produc...82E16817815001. It's a pretty good PSU and it is modular. Your other options would be to go up to a 750W like either of these: Corsair tx750 or Silencer 750. The 9800gtx isn't too power hungry so I'm pretty confident the 650W will run it if you didn't want to dish out for the 750W.

Alright, I hope I didn't offend you, I just don't want to spend more money than I have to on the power supply. Thanks for the help!

It's ok, it would suck to get a brand new PSU only to realize you don't have enough connectors.

For 2 GTX's? I would stick 700 and up but maybe thats just me. Also 4 hard drives will be gettin your watts up there. I would say a silverstone or pc power and cooling 750 watt would be more suited for the job.

Even overclocked, I really doubt he will see much more than 450W consumption. The 9800gtx uses about as much power as the 8800gts 512 which was ~120W. His processor even overclocked will barely hit 100W. Even if he overclocks his 9800gtxs 20% were are still only looking at ~400W. His HDs will need ~80W at spin up but the rest of the time will need no more than 10W each. There is nothing wrong with getting a 750W like the Corsair, it's a good deal and will have more overhead for better efficiency and less heat and stress on the PSU. But if he wanted modular, there's nothing wrong with the 650W for his rig.

From what Im seeing they can easily use 250 watts ea on load and about 100 for the cpu is 600, 650 for the hard drives, and 100 for leaving room..just the way I look at it.

250W each? For a 9800gtx? Not even the gtx280 can hit 250W and that needs a lot more power than a 9800gtx. Please show me where you saw a 9800gtx needing 250W by itself.
