hello i am currently using a dell inspiron 3847 which ive gotten a couple years back. Now that i plan to upgrade the gpu from a gt705 to a gtx1050ti, i think i may need to upgrade the PSU as well. Now i know that there are other posts about this but i would like to ask if i could buy a corsair VS450W instead of the CORSAIR CS750M (which everyone is recommending) since its a little pricey for me. My current PSU(Dell PSU that came with it) is only 300W. My cpu is a core i5-4460. Thanks
There are specific models that I have tried and they work fine.
CORSAIR CS750M works CORSAIR CX750 DOES NOT
lower power versions like the CS550M and CS650M do not have enough 3.3v/5v combined power.
EVGA NEX 750B works fine.
Power supplies that do not have 150W combined on the 3.3V/5V rails may not EVER work or may fail. Note the power ratings on each rail
This label is from the NEX 750B1
This is a label from a Dell 525w unit. Note the ratings on EACH rail not just the total watts.
On many other vendors as the power goes up the 3.3V/5V rails max power GOES DOWN to 100W max. However in the case of dell 875w unit the power goes UP to 225w on the 3.3V/5V rails.
This is what the NEX 750B1 looks like installed in an XPS 8500
