If anyone was interested, I managed to find out the power supply is a 12V 500W. It's basically an 80+ Platinum power supply. it was this code here: 12MXJ : MOD,CHAS,L6,500W,EPA,L,5000 If anyone knows the others I'll mark yours as the solution, but for now this is the information I was mainly looking for.  
Hi Dell Gurus!  Hope you had a great Christmas and New years!   Please may I ask whether there is a support page that explains the codes on the "System Configuration" page. When I open it up you have to decipher the codes, I don't know what they mean, I can make out CPU and GPU details as I know what I'm looking for but any more detail like what the power supply is not readable for me. I'm quite new to PCs so I'd really appreciate any help. To give an example, I've screenshot one of the components/software that doesn't make any sense to me.[IMAGE] Please let me know if you know. Thank you  Kind regards, Yogi
