Is 400w Enough?

[mjones1]

At the moment i have all the hardware in my signature with a dvd drive and a raptor hard drive.
i have this power supplyI have a Akasa AK-P040FG8-BKUK 400W Green Power 80
Would i need to upgrade if i wanted to buy a 4870?

When I had my overclocked E8600 and 8800gtx I was pulling around 330w ~ full load.

Most sites recommend a PSU with 32A +12V rail for the 4870. Therefore might work, but most likely be running it at high load which could result in instability & or failure of the unit over (short) time.

Your 400w PSU should be fine.

does a gtx w 260 take less power?

What's your max budget? Ask because you could squeeze in this PSU & not have to worry about that part again Could also sell the Akasa & put the money towards it

Ignore those online calculators. The power estimates they come up with take the ****. Honestly if you get a power meter and see what your PC is really drawing it will be nothing like what people recommend.

Are OCZ PSUs good quality .... I'm about to embark on a (low budget) upgrade/build for my kids PC and need a PSU. Before TWO I was leaning towards the Corsair VX450 - which I have in my main PC as was only extra £6 ... but differential is now £12 so OCZ is now more attractive!

Since they bought PC Power & Cooling they seem to be putting together some good units. The new range(s) seem to get good reviews

there is a good article on PSU power at X-bit labs. Have a look at this page on a gaming PC with an E8600 and a HD4850
