Is this PSU defected?

[Mascarpone]

Hello.

after a bit of surf on the web, i decided (mostly basing my choice on this site summer roundup of PSUs) to buy a silverstone DA 750. Unfortunately, when i opened the box, i saw that the EPS port has just 23 pin on the plug....

is this normal or is it a defect? Since it's modular, should i change just the wire or the whole PSU?

here's a photo....

it's most likely a "common" as seen here: http://www.marnscda.com/Guide/Short24pin.jpg

May not be needed though it's hard to be 100% certain without a proper diagram.

It is missing the -5v, which is perfectly fine as ATX version 2.2 specifications obsoleted that voltage. This means any modern PSU will not be able to power older computers that do not run their CPU off +12v. Examples are Pentium III boards and older.

yeah thank you guys... also i noted that if you look at the photos on the review of the DA 700 on the site you'll see that even there the PSU miss a connector....


Anyhow i have a doubt. Here's the spec from the site:

1 x 24-pin motherboard connector (550mm)
1 x 8-pin EPS12V connector (550mm)
1 x 4-pin ATX12V connector (550mm)
1 x 8-pin PCI-E connector (550mm)
2 x Dual 6-pin PCI-E connector (550mm)
2 x triple SATA connector (500mm +250mm + 250mm)
2 x triple 4-pin IDE & single floppy power connectors
(500mm + 250mm + 250mm + 150mm)


I will use the pc for CUDA, so i will use many Geforce Card not on SLI. I see a 8 pin Pcie and two 6 pin... How do i know if my card is a 6pin or 8 pin? And if i would need two 8 pin cards?

Well it depends on which nVidia card you get. If you look below, I've included a couple of links to pictures that will show you what I'm talking about.

Below is a nVidia 9600gt w/1x6 pin PCI-e power connector. (5th picture from the left)

Good eye, I had my view flipped. 😉
