Earth Watts 380 enough for an old phenom II system?

[Beowulff83]

I am trying to build a Extremely  low budget system for gaming in my sons bedroom.  Foxconn A78AX AM3 motherboard, 8gb ram, Phenom II 955 cpu, HD7850 1gb graphics card,  probably a standard hdd.  I am looking at a USED Antec Earthwatts EA-380D Green Power supply.    I will be overclocking both cpu and gpu.  I have the feeling it won't be enough for the overclock.  What say the experts, will it work?  If not any suggestions for a psu in the $20 range?

Probably wouldn't recommend a used PSU, if have a low budget to play with I recommend you look at a Corsair CX450M (gray label).

Looking, Phenom II 955 is 125W, and HD 7850 is 130W, that's 255W.

Overclocking that starts pushing it bit too close since EA-380D has a 12V max load of 336W

336-255=81W left… that's not much at all.

Phenom sits at 125w without overclock and radeon at around 130w , depends on implementation might be higher.

If you add ram,hdd,motherboard and various usb devices I don't think it is wise to overclock with that power supply.

In addition, these components are a bit old and if were already on a working pc all these years they might consume a bit more power due to degradation.

I will use a better power supply at around 450w and not push too much on overclocking.

You can overclock both and it will use less than 380W, but I just wouldn't do it on that old, used unit.
