new psu wont power pc
i ordered a new 530 watt psu to power my pc because of a graphics card i got from a friend ( ati radeon 1gb ddr3 4800 series) and when i connect the psu the standby light turns on but if i hit the power button nothing happens. i know the psu is not faulty because i did the paper clip test and im currently powering my graphics card only via the new psu and the rest of my pc with the old psu. also the psu is a rx530ss atx psu. any suggestions so i dont have to run two psu at once??
The paper clip "test" only tells you whether the PSU is able to turn on at all or not. It does not tell you anything about whether or not the PSU is actually capable of delivering the amount of power you are trying to pull out of it reliably.

Assuming you are correct about this and all the DIMMs appear to still be in place, there are a few possibilities:
- you may have nudged some of the DIMMs out of their slots, try re-seating them
- your CMOS settings may have been corrupted by bad power (you should have gotten a CMOS checksum error message on boot in that case)
- your RAM or chipset/motherboard got damaged by bad power and now some of the DIMMs no longer register
