370w enough for HD4870?

Need some advice / opinions from the PSU experts here.

Currently I have a HTPC/gaming rig running a HD4870, Phenom II 710 overclocked to 3.4 at 1.325v, one 7200rpm HDD, 2 sticks of ddr3, and a LG GGC (actual rig in sig). Currently a 520HX is powering this and there will be no more additions made to this rig.

I'm also planning on building a server 08 that will ultimately be running 12 HDD, 4 case fans, possibly 3 (total) PCI/PCI-E x1 cards, Phenom II quad non overclocked, onboard video, and 4 sticks of ddr2. And maybe even some USB powered deviced down the road.

RIght now I have a PCP&C 370w running my whs (which will be dismantled for the server 08 build) and I am contemplating on whether to swap these two PSUs.

My questions are would the 370w be able to power the HTPC/gaming rig safely and stably? Or will the 370w be fine powering up and running the server 08 configuration mentioned above? I understand it could possibly run up to 300w for powering up 12 HDD. The server would only be powered off for hardware maintenance. Otherwise it would stay on 24/7.

I know I'm probably better off buying a new ~500w PSU for the server also, but right now I'd prefer not to spend any more money if possible. Thanks in advance for any suggestions.
 
I believe the Silencer 370W will be enough for either application, although you'd be pushing it a little in both cases. I recommend a PSU upgrade.
 
I think the Silencer 370 would be barely capable of powering the HTPC/gaming setup.You would pushing it to 100% load. I would not recommend using it with your HTPC/gaming rig.

For the server setup, not recommended either.

You can calculate your power needs yourself using this website.

If you find that your power output is close to or over 100% of the PSU capacity, then it's probably not sufficient. You want to give yourself some reserve buffer power.

I used a similar power calculator at http://www.antec.outervision.com and the recommended PSU wattage for my HTPC/gaming rig setup was only 295W. But I'm not too sure if I trust that number.
