Core 2 Duo Heatsink with Core 2 Quad CPU

[reginalddeanferguson]

I have Dell Optiplex 780 Mini Tower with a E8600 Core 2 Duo and I have ordered the Core 2 Quad Q9650 CPU, I have read I need the performance copper heatsink and I plan on ordering one next week, however will this heat sink from the Optiplex I have now work for now until I can order a new one? This is the stock heat sink I have right now https://www.ebay.com/itm/Dell-K2NV1-Optiplex-780-Heatsink-and-Shroud/132076986271?rt=nc&_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D2%26asc%3D52935%26meid%3D6f8b1196e3c4492a984e6a521036f139%26pid%3D100005%26rk%3D3%26rkt%3D12%26sd%3D232853075377%26itm%3D132076986271&_trksid=p2047675.c100005.m1851 I also have artic silver thermal paste. Would it be okay to use the stock heatsink until I can buy a new one?

The 6 pin on a single rail aftermarket PSU already has the 3x12V. wires for the 150W 8pin. The 6 pin only uses 2 of them. An extra signal wire on the 8 pin allows all 3 to be used. So 6 to 8 pin adapter is OK. On multirail PSUs like Dell and HP the power is budgeted more tightly. Many 8 pin GPUs don't need the full 225W 8pin provides. Many need barely more than the 150W 6 pin provides. See what the TDP of your GPU actually is.

Okay so for an example this psu would be 336 watts on the six pin?

The 12V. rail for EVERYTHING would be 336W. CPU, GPU, drives Everything 12V. If you pull 225W on an 8 pin GPU there won't be much left for anything else.
Here is a test of the Dell 305W PSU. Bear in mind that the Dell rating is continuos and the aftermarket is peak output.

If you want to run an 8 pin PCIe card i would suggest at least a good quality 500W PSU.

Sorry for all the questions.
I found a evga 500 watt psu it only has 6pin+2 pcie would I use all 8 pins or would I use a 6 to 8 pin adaptor on the 6 pin part or do I need to find a psu with one 6 pin?

The 6+2 makes an 8 pin. As I said the 12V. power wires are the same so this works. I like EVGA PSUs.

Okay, so I have all new 8 gen parts and a MSI gaming motherboard the B360 and I decided to buy the same brand Corsair memory, case and psu I am all set to begin installing everything once my case arrives today. One thing I do not understand is connecting the power supply. The motherboard manual says to connect cpu_pwr1, atx_pwr1, and pcie_pwr1,although I have read connecting pcie_pwr1 is not necessary, it is only for overclocking, but the motherboard manual says to connect them all. I am using the corsair vs550 psu and I have a msi gt 730 gpu. I don't plan on overclocking. Should I connect all three power connectors? Even if I don't need pcie_pw1 will connecting it anyway cause any harm?

ATX PWR1 is the 24 pin MB connector, CPU PWR1 is the CPU 12V which is usually a 4+4 connector on an aftermarket PSU, use 4 or 8 as needed by the MB.
PCIe PWR1 is only needed if the GPU requires it and will be a 6+2 on an aftermarket PSU. The rest of the cables will be for the drives mostlt SATA but usuallly an FDD, and 4 pin Molex will be there also.

Okay, I got everything installed and it is working great. Thank you for all your help.
