Trying to find specs

I have a Dell OptiPlex 760 MT
Intel Core2 Duo E8400 3.0GHZ
300W Stock PSU (Corsair CX500 PSU available if needed)

Looking for specs/ knowledge on how many watts/amps are available at the PCI-E Slot on this specific Mobo.

If it matters the reason I need this info is that I'm upgrading the GPU and will most likely have to modify the card to make it fit. Don't want to get it in there and find the Mobo doesn't supply enough amps for the level of card I need.

P.S.: Tried asking this in the Graphics Hardware forum and only got suggestions on different cards that don't perform to my needs.

Thanks for any help concerning the specs of the Mobo!

75watts or 75/12 = 6.25 amps is the PCIe std for the slot, any more power hungry GPU will need power connector from the PSU.
You will not be able to modify the card and leave it working.

Why dont you just get a cheap mid tower case instead of trying to physically modify any GPU. Youll void your warranty instantly. Can get a cheap case for $20.

My mistake, won't touch the card itself, just the mounting bracket and fan enclosure.

Nice! Do you know of any cases that I can put my stock Dell Mobo in? Or do I need to scrap that Mobo and get a new one as well.

Depending on the size, you can get just about any case youd want. If its a micro-atx then any mid tower will do.

Well like I said it's a Mid-Tower so ATX but I'm almost positive the Mobo mount locations are Dell proprietary. So given that, I'm pretty sure I'm stuck with this case.

Unless you're sure that Dell Mobo's aren't proprietary anymore, but I can't find anything on the line that says so. :)

Well that would definately be an issue if the holes were different. Never worked on a Dell or owned one.

Also I had this question of you rolli59:

The video card manufacturer and seller are recommending buyers make sure their PCI-E slots have 12v/20 amp service. Are there Motherboards that meet this requirement?

240watts through the slot! No! PCIe power
"Power

All sizes of ×4 and ×8 PCI Express cards are allowed a maximum power consumption of 25 W. All ×1 cards are initially 10 W; full-height cards may configure themselves as 'high-power' to reach 25 W, while half-height ×1 cards are fixed at 10 W. All sizes of ×16 cards are initially 25 W; like ×1 cards, half-height cards are limited to this number while full-height cards may increase their power after configuration. They can use up to 75 W (3.3 V/3 A + 12 V/5.5 A), though the specification demands that the higher-power configuration be used for graphics cards only, while cards of other purposes are to remain at 25 W.[10][11] Optional connectors add 75 W (6-pin) and/or 150 W (8-pin) power for up to 300 W total (2×75 W + 1×150 W). Some cards are using two 8-pin connectors, but this has not been standardized yet, therefore such cards must not carry the official PCI-Express logo. This configuration would allow 375 W total (1×75 W + 2×150 W) and will likely be standardized by PCI-SIG with the PCI-Express 4.0 standard. The 8-pin PCI-Express connector could be mistaken with the EPS12V connector, which is mainly used for powering SMP and multi-core systems."

Thanks rolli59! That's the kind of info I needed. The manufacturer and seller weren't clear enough for me. They meant ot say the 12v rail needed 20A! Darn!

So that being said thanks to all, I have the info I needed (no thanks to the dolts at manu. and sell.!)
