Well guys, I am about to build a new system here in a few weeks. The one thing I am not sure about is the PSU. Here is a list of my main components:

  • WD Caviar 500GB 7200 RPM 16MB Cache SATA HDD - http://www.newegg.com/Product/Product.aspx?Item=N82E16822136073
  • EVGA GeForce 8800GTS (G92) 512MB OC- http://www.newegg.com/Product/Product.aspx?Item=N82E16814130325
  • AuzenTech Auzen X-Fi Prelude - http://www.newegg.com/Product/Product.aspx?Item=N82E16829156005
  • 2x(8GB in total) G.SKILL 4GB(2 x 2GB) DDR2 800 (PC2 6400) Dual Channel- http://www.newegg.com/Product/Product.aspx?Item=N82E16820231122
  • GIGABYTE LGA 775 Intel P35 ATX All Solid Capacitor Intel Motherboard - http://www.newegg.com/Product/Product.aspx?Item=N82E16813128059
  • Intel Core 2 Quad Q6600 Kentsfield 2.4GHz - http://www.newegg.com/Product/Product.aspx?Item=N82E16819115017
  • 1xDVD+-RW Drive. Just basic.


    I have looked up on both New Eggs PSU calculator (which rated it at 650W) and Outer Visions eXtreme's calculator (which rated it at 400 watts). I normally have about 6-8 USB devices connected. I am guessing that a 600 watt PSU would be fine, but it do want it stable (I play a lot of games and render high quality lighting and hi-poly models) so if you guys think I should get more... Finally, do any of you have specific models (links) or even just brands that you would recommend for this setup? Thank you all in advance for your time.

    Another question that is kind of off topic, how big of a jump would you think I am going to see in performance compared to my 7950GTX OC, 2g DDR, and a AMD x2 4400+? Keep in mind that I am going to be running Vista 64 Ultimate and am now running XP 32 SP2.

    what he said :) 


    I believe the additional 2 GB of RAM will help a lot with Vista, and the quad will help a lot with the rendering (assuming your software is smart enough to use all cores - you'd better check, and maybe get an upgrade). The 8800GTS 512MB is very fast. There are some benchmarks here:

    http://www23.tomshardware.com/graphics_2007.html?modelx=33&model1=706&model2=708&chart=297
    I used 8800GTX instead of 8800GTS G92 but at that resolution they're almost identical. I used 7950GX2 as the closest thing to the 7950GTX in the list. The performance in Oblivion at 1600x1200 is about double, from weak 17 fps to playable 32 fps.

    Make sure you get a SATA burner, not IDE. The SH-S203B is pretty good.

    The 750GB Caviar (WD7500AAKS) is way faster than the 500GB Caviar.

    That's a very expensive sound card. If you have $50 speakers I suggest sticking with onboard audio instead. A sound card like that needs something serious, like Z-5300 or Z-5500.

    Thank you all for your help. The sound card is on purpose. I have 5.1 digital SS speakers, the Z-5500 actually lol. I use Maya, Houdini and 3DSM and I do believe that Maya 2008 supports Quad Core so that should be great. Few questions about responses:

  • Is there any reason to get an SATA burner instead of just using my old IDE one. I really never use CDs anymore and the whole point of even having one installed is for installation of software/games anyways. Most of the files I work with would just be a pain on any compact disc, some are almost 10 gig files...
  • "750GB Caviar (WD7500AAKS) is way faster than the 500GB Caviar. " Why is that, on the specifications they have the exact same seek and write times. Is there something else I am missing. I honestly don't need the space, I have a server with like 2 TB of space, so if its only a space difference...
  • "2 GB of RAM will help a lot with Vista". This will be my first time using Vista for a long period of time. Do you really think it needs 10 gigs of RAM, or did you not see that I'm getting 2 of those 4 gig packs for a total of 8? I do know that RAM has become an issue to me. I actually max out my 2 gigs opening 1 photoshop file sometimes now (panorama's of 10 MP images)...

    Finally, a last question. I have seen the TH VGA charts before, my question is, is that 8800GT G92 OC at the top the same as my card. I only ask because I can't find a GT G92 anywhere and mine is GTS. If not, then how big of a difference can I expect in performance.

    Once again thank you. If anyone else has a suggestion or just some information, I like to learn :) .

    Watts is not the important metric for a PSU. Look at the total amps delivered on the 12v rails. A typical pc with a 8800GTS needs a psu capable of delivering 26 total 12v amps. All of the quality psu's mentioned will do fine. A cheap psu will deliver watts on non-12v rails, to inflate their specs, and do so at 25c which is unrealistic.

    My pc is somewhat similar to yours, and I do fine with the PC P&C silencer610 (s610eps)mentioned earlier. It delivers 49a on a single 12v rail. It is, perhaps even overkill.

    The 8800gts is a slightly higher clocked 8800gt with a better cooler. I think the gts is 5-10% better than the gt

  • LOL indeed, the Z-5500s are brilliant with a good sound card. I have the Z-5500 with X-Fi XtremeMusic and love them. Good choice of sound card too with that Auzentech, because X-Fi and Vista don't go that well together from what I've read. Mind you, maybe Creative fixed the drivers by now.

    Sure, if you have an IDE burner use it. I was just thinking if you need to buy a burner anyway to avoid the wide IDE cables, they're a pain to manage and block airflow. It's not worth paying $30 just for that though.

    The WD7500AAKS uses perpendicular recording, which allows higher density and increases the average read/write speed on large files (assuming they are not very fragmented). For example I have both types in my PC and I see that the 750GB disk works better for handling videos. WD6400AAKS has it too. Seagate 7200.11 models also have it.

    8800GT cards are all G92, so retailers don't bother adding it. They doi add it for the 8800 GTS G92 512MB because that is a different animal from the 8800GTS 640Mb and 8800GTS 320MB (it's newer, faster than both, uses smaller transistors). The card you picked is an excellent choice. Very few cards are faster (8800GTX, 3870X2, 9800GX2), and not by much and not in all games and they are way more expensive.

    Vista and RAM: oops, I missed that, I thought you were getting 4 GB and I was comparing with your old machine with 2 GB. Yeah, you're getting 8 GB and that's the most the DS3L accepts anyway. Nice work. I remember my Dad struggling with AutoCAD and lack of RAM was the worst problem.

    PSU: you don't need 750W. I got that Silencer 750W myself, but I have 5 hard disks and 2 burners and my 8800GTX OC2 consumes more than the 8800GTS G92, and I wanted to buy something future-proof - as in, to support the best video card of 2010. If you don't have plans like that, the 550VX or the Silencer 610W or the Corsair 520HX or 620HX are all fine.

    Well, at best, it can do 14% better at the same clock (128 stream processors instead of 112). Of course, that's the ideal scenario, it won't always be 14% faster. The better cooler part is important, because the single-slot coolers on some 8800GT cards are a pest. The heat remains in the case instead of being pushed out, yuck...

    Thank you all so much, all your information has been very, VERY helpful.

    I think I will end up going with the "PC Power & Cooling S610EPS EPS12V 610W Continuous".
