My friend upgraded his HP which is a pre-built with i7-4770 and 16 gb ram with a 960 2gb. I asked him if he upgraded the PSU he told me no and that it was a 450w. Do you guys think I should recommend a reliable 430w or a 500w to be safe? Thanks guys :D

reliable 500w is more futureproof or even better 650w or more

500W PSU would be recommended.

I say jiggly-bytes when I see "GB".

It goes down better than you would expect.

If the OEM PSU is a good brand IE Delta, etc then it should have no issues. I ran F@H on a 10 year old delta 450W PSU powering an HD6950, not the slightest complaint

450W should be enough, but if it is some random no-name brand that can't deliver what it promises, there could be issues... and fire :)

All the HP prebuilts I test with(bare in mind these are Pro/EliteDesk PCs) use Delta PSUs and I have never had a problem with them, and they run basically 24/7 on my test bench.

The biggest thing to be aware of is that not all of them have PCIe power connectors on them. Also, there cases(at least in the case of Prodesks) don't use ATX form factor PSUs, so you have to figure out how to mount the thing if he did upgrade.
