These are the parts that I'm going to purchase soon, but I still have some questions (non to be purchased online, all from local shops)
Motherboard: XFX LGA 775 NVIDIA nForce 780i SLI
Processor: Intel Quad Core Q9300 2.5Ghz
RAM: Corsair 2GB 800Mhz (x2)
HDD: Western Digital 500GB 7200rpm
GPU: XFX Nvidia Geforce GTX 280 1GB GDDR3
PSU: Gigabyte 800W (???)
Case: ASUS Vento 7700 or Gigabyte Aurora (???)
OS: Windows VISTA 64bit Home Premium Edition
Will the 2 following parts: the 800W Gigabyte PSU and ASUS Vento 7700 Case be able to accommodate the other parts in terms of power (PSU), space/cooling (case)??
(NOTE: Newegg currently has 2 versions of the gigabyte 800W psu the only difference I noticed is one has a software for changing some options while the other doesn't come with the software)
(The gigabyte aurora uses 120mm fans (one front and one in the rear) and the Vento uses 2 80mm fans in the back ( i think there is space to add an extra fan in the front))
(This is unrelated to this specific section but any info is appreciated )I also found in the market a Gigabyte CPU cooler 120mm (GIGABYTE GH-PSU23-PB 120mm EBR CPU Cooler). First is it a necessary purchase and will this piece fit with the motherboard and will it allow enough space in the case (also considering a future SLI)?
(I have posted this also in the homebuilt section of the threads, sorry for double-post. figured this is the best place to post my questions but I didn't realize it at first)
Single GTX 280
"A GeForce GTX 280 requires you to have a 550 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the 12 volts rails."
2 way SLI GTX 280
"A second GeForce GTX 280 requires you to have a 800 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 55 Amps available on the 12 volts rails."
based on the above from guru3d.com and Gigabyte's product specs for the 800W PSU both models (GE-M800A-D1 and GE-S800A-D1);only difference is the GE-S800A-D1 comes with software control and 4 diodes for temperature detection, can run the GTX 280 Single and 2-Way SLI.
Both models have the same current outputs:
+3.3V = 30A, +5V =28A, +12V1 = 18A, +12V2 = 18A, +12V3 = 25A,
+12V4 = 25A, -12V = 0.8A, +5Vsb = 3A
I would just like a confirmation ASAP from the experts at tomshardware then its off to get the parts and building
