hardware question

[Rattler5150]

I have a Lenovo S20 thinkstation that I have been upgrading
Xeon proc, 12gb ram, 1tb data drive.

the power supply is 625 watts, unfortunately upgrading it is going to be tricky to say the least.
In addition to the ATX24, and the 4pin power connections to the motherboard, there is a 10 pin power connection I have never seen anywhere else.

I was thinking of putting in a Geforce 580 or 680 graphics card

Is 625w enough?
2 platter hard drives
1 DVD
6 sticks of ram DDR3. 2gb each

Well think of it this way: is it going to prevent you from upgrading if you have to get a new psu? Or will you just bite the bullet and find the psu you need?

What does that extra 10-pin connector go to anyway?

Actually, you sure it's 10 and not 8? EPS12V is defined in SSI, and used primarily by SMP/multi-core systems such as Core 2, Core i7, Opteron and Xeon. It has a 24-pin main connector (same as ATX12V v2.x), an 8-pin secondary connector, and an optional 4-pin tertiary connector. [http://en.wikipedia.org/wiki/ATX#EPS12V]

yes 10 pins, 5 black on one side, 5 yellow (indicating 12v)
it goes to a header on the motherboard, this is a Lenovo workstation not a typical desktop

The 580 requires a minimum 600 watts I believe, so you should be ok so long as you don't plan on clocking anything beyond stock settings. You might be pushing it though.

Personally, I would upgrade the power supply, but it's up to you of course.

it depends on what power your psu can actually provide. If it's a top tier psu you'd probably be fine with it, but close. If not, you almost certainly need to upgrade.

The power supply issue is the reason im here. I cannot put a standard PS into it because of the 10pin mobo power.
A lenovo part will cost over $600

I'm pretty sure 625 Watts is enough. If you want to be on the safe side of things, you can do a little upgrade. I have a 580 myself, but I think my computer came with 750 Watts. You can ask a store technician to be sure, or do a little googling.

PS. Megadeth Rocks.

I may have to do some modding to do what I want. I can get a ATX power pin extractor, take the 10 pin plug off the existing PS, put it on my 750watt,using the 8 pin and a spare 12v plug.
that may work (crosses fingers)

Pics of the power supply?

Alternatively, take this question to the Bit Tech forums! Some real hardware know-everything types lurk around there.

Anyway, GTX580 on a 1366/x58 based computer would be pushing it, 580s need a lot power. A GTX 680 would be fine as they draw much less power. Even with a big old X58 motherboard I'd bet you would stay under 500W at full load.

The Power supply is sufficient. However if it is a specialist PSU does it have the two 6 pin/4pin GFX card connectors?

Should power a 670 no probs (is more power efficient than a 580 but not as demanding as a 680) if it has the connectors.
