Spec me a PSU

MikeHiow · 18 Oct 2010 at 20:35

Need a cheap as possible PSU for a cheap build.

E6300 @2.8GHz
2GB Ram (will need 4, but doubt this will have much impact)
A single HD
ATI 4890.

corsair cx430w

Yep, the Corsair fits the bill perfectly

Does anyone have the ampage ratings for each rail?

RJC · 18 Oct 2010 at 20:57

Link below should help:

28A on a single rail - is this going to be enough? According to the internet, the 4890 peaks at nearly 23A alone.

Interesting. I thought most PSU makers these days didn't add rails together to make the rating of the PSU sound better.

I don't think a HD4890 draws as much power as 276W though, 2 x 6 PCI-E connectors (75W each) plus the slot (75W) only adds up to 225W. I think it pulls about 200W, so 17A.

Just had a thought the Corsair only comes with one PCI-E connector so you would need to use a molex to pci-e 8 pin.

Some alternate PSU below:

The sapphire (2nd link) is a really nice PSU and could last through an upgrade or two, but it is more expensive than the corsair and it all depends on how much money you want to spend

MikeHiow · 18 Oct 2010 at 22:25

As little as possible

Jony27 · 18 Oct 2010 at 22:29

the sapphire 625w is currently out of stock with no ETA

Corsair CX 500 (spec)

MikeHiow · 18 Oct 2010 at 23:11

Ordered a CX500 - more than I really wanted to spend, but I guess its a little peace of mind, and hopefully a bit of future proofing.
