460w power supply question

i did set to high performance plan in power options.

i did set my cpu fan speed at highest rpm in BIOS.

i did set my AMD Radeon RX 640 graphics card fan at highest rpm in SpeedFan app.

Because i live in my warm or hot room by the time when winter ends.

Will this 460w power supply work for my optiplex 5080 mini tower??

I know AMD Radeon RX 640 graphics card doesn't needs higher than 260 w power supply but i like to use 460 w power supply

I agree w chino. It is fishy.  Dell genuine oem psu brand are delta, liteon, chicony and huntkey.  This unheard of brand on Amazon puts a Dell oem factory label on listing pic but no actual pic of psu.  I would stay away.

In agreement with both Chino and redxps.  The RX 640 is only a 50w card.  No need to upgrade PSU; wouldn't be any added benefit if you did.

It's a non-Dell brand.  So, only seller can give you a definitive confirmation.  But, they already advertised that it is compatible with OptiPlex 5080.  

If you have no higher power needs, there is absolutely no benefit to change out your OEM 260w PSU for an unfamiliar brand aftermarket one.
