Would it be okay to use a 300 watt psu on a build that uses ~250 watts. I am not OC’ing or anything

What PSU? What specs?

 

Most 300W PSUs are pretty crap.

My account is almost entirely dormant. Hope you all are having a grand time. Many years of fun were had here.

Well if my friend is being truthful, he said it is a dell psu, but those are typically rebranded psus. Iam unsure. But i would need it to power an i7-860, HD 7770, Asus Sabertooth 55i mobo, and 8 gb of ram (one stick)

I hAve an unfinished pc build. Pls dont bully for not having one yet or i cry.

You'll want to find one with around 400 watts instead. They will be higher quality and have a higher efficiency.

Read above

I'd get a new one as Dell PSUs from that time are s***

save up, eat some cup noodles, sometimes there are $25 PSUs that are good

can you look on the PSU and list the model or serial number

i have seen many Dell Optiplex systems in the past few years and a lot of them had 250-350Watt PSU and were even 80+ Gold rated

havent seen any of the optiplex power supplies fail so far 

 

300watts is enough to run for your system but i would strongly suggest disabling intel turbo boost 

you can probably even undervolt the CPU to use even less power without issues to stability 

 

but please list the model number so we know exactly which psu it is

If that PSU doenst have a PCIe 6pin then you cant power the HD 7770

You solder two SMD 0 Ohm Resistors next to the PCIe connector. Then you don't need it.

0 Ohm resistor = use solder to draw a line?

 

Besides, that's too much for OP who clearly doesnt understand why we care about the PSU of choice so much
