My computer doesn't power on when my gpu isnt connected, one day i was playing h1z1 pretty late and in the middle of a game the computer just turned off and it didnt power on, i thought it was the mother board or power supply but i did the test with the paperclip to see if the psu works and it indeed worked so then i took the graphics card out of the pci slot but its still being powered and the fan spins, but when i put the gpu in it doesnt wanna turn on but occasionally when the gpu is in itll try with a little fan spin

It's possible when you were playing that the demand meant the graphics card needed more power which wasn't available to it.

The wattage will depend on what graphics card(s) you intend to use in future. Manufacturers tend to list their minimum requirement and generally speaking most PSUs are most efficient at half load. I believe 600W is enough for most normal use cases, but again it depends on the graphics card being used (for example, MSI's r9 390x has a 750W recommendation).

While software monitors like HWMonitor won't provide the best accuracy for voltage readings (actual hardware testing is best), they can give an indication as to whether the PSU has issues.

430 EVGA power supply, MSI AMD R7 265, AMD Athlon A8 duel core, Gigabyte flexible motherboard, 500 HHD, Roosevelt case, I'd say 2-2.5 years, sorry about the late relpy

Oh I was just puzzled because it's been working fine before and then it just shut off one day, but ig it's time to do some upgrading or just a new power supply

Oh, thank you very much I plan to future upgrade new case and everything but ima scrap the hard drive and ram to a gtx 1070 or 1080 in the near future so i suppose ima need a 600 or 700 to future proof?
