PSU advice needed

Jonny Chee · 24 Dec 2012 at 14:36

I currently have a CoolerMaster 460w PSU but am upgrading my graphics card from a 6850 to a 7950. I will also be overclocking both my card and my CPU (which is currently at stock).

I feel I may get away with current PSU but also feel it's possibly a bit risky...

So firstly, do people think I need to upgrade, and if so, could you recommend me a PSU?

My build will be:

CPU: i5 2500k (will be overclocked)
MOBO: Gigabyte Z68AP-D3
RAM: 8GB DDR3 1333
GFX: HIS 7950 IceQ Boost
HDD: 500GB Seagate SATA III
1 x DVD-RW
CASE: CoolerMaster Elite 330
MONITOR: 22" 1080p @ 60hz

Do you the Model of the PSU as some of the the Coolermsater ranges were not great.

But the PSU below will be fine if you do fancy a change.

You can get away with it but you're right it might be risky.

If you really want to get a new PSU go with the Seasonic one. If that's in your price range.

If not the XFX one is perfectly fine when it's in stock.

YOUR BASKET
1 x Seasonic G series 550w '80 Plus Gold' Modular Power Supply £72.98
1 x XFX Pro 550W Core Edition '80 Plus Bronze' Power Supply £59.99
Total : £143.47 (includes shipping : £8.75).

There is also the BeQuiet range..

I was going to recommend that as well but it's only a 40W upgrade. If you're going to buy a completely new PSU at least go for a bit more

Well I did think of that but the op's system with the 7950 is not going to pull a great deal, but if his Coolermaster is one of the better ranges he might be able to get away without issue.

True.
Which type of CM PSU have you got OP?

I am not sure of the exact model as it came with the Coolermaster Elite 330 Case when I bought it in 2010.

According to my order it is just listed as Coolermaster Elite 460w PSU.

Not a very good write up:

So an upgrade required then?

The power and cooling suggested by RJC is seasonic and is a very good PSU. The seasonic G series 550W is £10 more or so but it is Gold rated for efficiency so over the years it will help claw some of the cash back. I doubt the PSU you have now (it came bundled with the case for free didn't it?) is even bronze rated like the P&C PSU.

For a single GPU setup 500-550W is more than ample
