Hello fellow compatriots.

I bought a "Lenovo/IBM Series 3000 J115 (7387-26U)" from office depot. It's a pretty cool system with 250GB H/D, 1 GB Ram in 2x512 modules, 16x DVD R/W etc. The motherboard is a MSI-7283, and the pwer supply is 220W. The on-board video is Geforce 6100, and I wanted to play Hitman-Blood Money, which played (just!), so I purchased a MSI Geforce X1300 Pro card which expects 330W power. The system is also due an additional hard drive upgrade of a 500GB hard drive which I assume will also sap it of more power.

The motherboard is an MSI-7283 Ver 1.0.

The question is, if I upgrade the power supply to 450, or even 550W, will this kill the board? I am worried that I will fit a larger power supply and switch it on and the motherboard would start fizzing and smoking.

The graphics card is definitely soaking up power. It takes a while longer to boot since I installed the card and I am certain that its not the drivers per se that are slowing it.

Oh, and Hitman Blood-money runs like a dream.

I called Lenovo who basically said that they didn't know the answer to my question! (well, that's helpful!), and I also logged a service information request with MSI who said :

Regarding to your concern. This is OEM product. And we haven't any information
about OEM product. So please try to contact your reseller to get some help. Please
forgive for not helping you.

So, has anyone tried this or knows any info? Please help.

Mr Large.

A circuit will only draw the current that it requires to operate, As long as the voltages are the same you can use what ever size supply that will fit properly.
Make sure the pinouts are the same, it won't hurt a thing.
