Q9450
ABIT IP35 Pro
2 RAM sticks (DDR-2 800)

5 to 10 SATA HDDs (five to ten)

1 8800 GTS 512 MB/EVGA

1 capture card (using PCI-E x1)
1 or 2 SATA controller cards (using PCI-E)

1 Blu-ray/DVD SATA drive
1 floppy drive

And I don't intend to do any overclocks, SLI/use more than one VGA card.

I need to know what are the best Power-supply alternatives for me today?

Thanks! :hello:

Some standard 650w ish good brand,Corsair or PCP&P will do it, the HDDs are the main prob ofc so you will most likely need to invest in some 4pin > 15pin convertors. 8800GTS is pretty hungry so 26ish 12v rail to be sure.

http://www.newegg.com/Product/Product.aspx?Item=N82E168... has 6 SATA and enough Molex to do the rest, and a really juicy 12v rail...good brand as well so your new rig will be safe :)  It is probably overkill but its a good price after MIR.

Currently, I am looking for this PSU:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CORSAIR CMPSU-620HX 620W ATX12V v2.2 and EPS12V 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply - Retail

Do you think this is a good choice? What do you mean by 4pin>15pin convertors? Will the PSU be capable of connecting all HDDs? English is not my native language, I don't understand that comment either:

"8800GTS is pretty hungry so 26ish 12v rail to be sure. "

Another thing that I need to know - what kind of cables/connectors I need to purchase in order to use 10 HDDs with this PSU? My primary choice as PSU was this model, featuring about 12 SATA connectors:

But was returned due to defective unit. I don't have any refference about a way to plug 4-5 more HDs in one PSU that can only support 6 SATA (one of them will be used by the Blu-ray drive).

That PSU is fine as well, although you may run into problems if you decide to use more than 1 graphics card.

4 pin to 15 pin convertors is just a small lead that allows you to use the older 4 pin molex connector (think IDE hard disk) in a SATA drive. http://www.newegg.com/Product/Product.aspx?Item=N82E168...


The card you have chosen requires a large 12v supply, the corsair above supplies this and so does the PC Powerl & Cooling. Some cheaper PSU's would most likely be under this cards requirements.
