Will I be able to use this Power Supply

[macl64]

I originally started building my PC with a 500W PSU installed, however when testing my PC it went dead so I decided to use a PSU from an old computer. This PSU ended up working and so did my computer - it was 170W though.

When I tested my computer for the second time with the old PSU installed, I did not have my Hard drive and Optical drive yet - now I do. Despite it working without the Hard drive and Optical drive, will I be able to use the 170W PSU with them installed? Or should I get another Power supply.

Dont see why the addition of an optical and a HDD would make a difference.

the hard drive will draw about 8 watts , the optical drive less than that .


but I feel what you are doing carries some risk even if it will boot . The PSU could be running at a wattage that gives you very little head room .
Heat may kill it relatively quickly
