[SOLVED] Transformer upgrade for Dell i7 Optiplex

[alandb]

I have a Dell Optiplex 9020 MT i7 4790 3.6 Ghz with 32 GB RAM, 1 TB SSD. It has a 290 watt transformer. My old computer was upgraded with an EVGA 750 GQ that is about 1 year old. Would I benefit from installing the larger transformer and is it possible? I mostly use the computer for Photoshop and Lightroom.

First, don't use "transformer" when you refer to PSU (Power Supply Unit). Although there are (small) transformers inside the PSU, this is not the correct term.

Second - if your PC works fine in its current setup, there's no need to change it, unless you make some upgrades (eg more powerfull graphics adapter).

And last - many Dell computers in the past had incompatible (proprietary) PSUs, so before you do anything - download service documentation from Dell support site, and confirm your PC uses standard PSU.

The 9020 MB has an 8 pin MB connector in place of the 24 pin ATX, and a 4 pin CPU connector. So the PSU is different. There are adaptors. But the XE2 MT, and Precision T1700 365W PSU used the same connectors and had an added 6 pin PCIe cable (290W + 75W =365W). That would be the simplest upgrade for up to a 150W GPU.
