Need an opinion about how much power this system will draw

post #1 of 6
Thread Starter 
I am building a computer for a friend of mine at school with my main goals as follows, in this order:

1. Must play modern games and games for the next 2 years at atleast medium to high graphics settings

2. Must be under $1000, $800 prefered

3. Must be highly future proof and upgradeable

So for this build I have chosen the following parts:

NZXT Nemesis case W/ 400W PSU<-- I haven't asked my friend which case he prefers or even if he wants a tower or SFF or whatever, just chose this because I have the Nemesis Elite and love it, but the Elite was too much money for this build

Asus A8N-SLI

AMD 3700+ San Diego

XFX 7800GT <-- that cool one with the black and green cooler

512MB Corsair Valueselect DDR400, either 1, 2 or 4 of them depending on what my friend wants

200GB Maxtor Diamondmax Plus 9 HDD which I already have and agreed to give to him for free since I no longer need it

LG DL DVD burner

So for this build, and considering that it will not be overclocked, but also considering that I want to leave the door to future upgrades like a better GPU etc. in a few years open, should I keep the 400W PSU that comes with the case or get a Seasonic S12-500 for $130?

Chances are the PSU that comes with the case won't be be SLI Certified. It might not even have a PCI Express connector for the motherboard.
Nonetheless I really advise you not to use any power supply that comes with a case. They are usually really poor quality and can cause system instability and random resets. Overvolting them by mistake (using high end hardware on a bad PSU) can pose a fire hazard. Since this is a budget PC you can upgrade to an SLI Certified PSU later, just get a quality one for now (well known brands, somewhere around $85+). Make sure it's 24 pins and has a PCI Express Connector.

Hi Remonster,

I think you're on the right track as far as M/B, CPU and Video card. As for the case and power supply. I think you can do better for $130.00.
Try this link:
http://www.pricegrabber.com/search_a...+supplies&rd=1

This should get you started. Everything with life and computers comes down to personal choice or monies. :-) I'm personally biased to Antec power supplies. I had many of them from 350W to my True Power 550w. No problems with any of them, but again it's my personal choice and experience.

As for cases. If your going to purchase a separate power supply, then a case with no power supply is in the realm of possiblility. Try this link:
http://www.pricegrabber.com/search_a...ord=cases&rd=1
Some these case come with excellent power supplies, like Antec, Thermaltake, etc... I like Lian Li cases, but again it's a personal choice. If your looking at a budget with a nice case and good power supply, I think these links will help you decide.

Best of luck with your decisions, because there are so many...

Take care, :-)

hey, to stay within budget I'd take a look at either the sunbeam nuuo 550w psu or the Antec NeoHe 500. both cost less than the Seasonic (although I do think the seasonic would be the better choice)

and for the RAM... try to stay away from Corsair. their customer support has gone down the drain and they are getting out of the performance RAM business. take a look at g.skill, geil or OCZ

soloz2, I think the Seasonic you are refering to is the S12-600 correct? I was not going to put a high end PSU like that one in his rig either the S12-330 for $50 or the S12-500 SLI for $120.....

well yeah, ultimately the S12-600 is the best, but I think the 500w version would be fine for the rig you are putting together. I don't think I'd get less than a 500w psu though. it's better to error on the side of being too big than too small.

I have the S12-600 and I put a Sunbeam nuuo in my brother's rig. some comparisons for you: (the S12-500 will be very similar to my S12-600)

Both psu's are very stable, and have more than enough power... that said.

areas where the nuuo is better:

price (zipzoomfly 82.99 shipped a week or so ago)
looks- this psu honestly looks better than the seasonic, and it has a 3.5" bay drive w/ fan controller and temp display
modular... if you like modular

areas where the Seasonic is better:

more powerful
more efficient
quieter
runs cooler
non-modular... if you don't like modular


with all that being said, I think there are some other very good psus in the price category you are looking at. (with some rough prices)

OCZ Powerstream 520 - 130
Antec NeoHE 500 - 100
Antec Neo HE 550 - 130
Sunbeam Nuuo 550w - 85
Seasonic S12-500 - 120

All these psus are SLI ready and are capable of powering the system you are looking at building. Furthermore, all are quality psus and I think you will be pleased with any of them. I am a big fan of Seasonic, I love my S12-600 the only downside is that the cables aren't sleeved. I sleeved my own... and they look much better now, but in all honestly I couldn't do as nice a job as the factory could do.
