Experience Index must be wrong...right?

OK M8 , Example >

I can only see 4-pin plugs. I have one big four pin, and a small four pin. No six pins!
PSU model: Octigen 3294CC0Tg ATX 350W

350W is quit low power M8, i know this means a bit more £ but i would upgrade your PSU at the same time, the recommended in the spec for the card is 500w also if you upgrade your PSU you will have power to play with if your using a few peripherals.

Just some info for you Sycthus, your MOBO is 24 pin power supply and going through the 4890 spec your present PSU will struggle to run it adaptors are supplied with some cards (not sure why the chap in the review had a prob with Molex adaptors, i have found they work in the past)

Your MOBO


The 4890 has two 6 pin power inputs ... because the card draws more power than can safely be drawn through one plug, all cards above the 4870 require 2 power plugs, each 6-pin can supply up to 75W of power, along with the motherboard which can supply either 75W or 150W depending on whether it is PCI-E 1.1 or 2.0. The 4890 itself only requires about 120-130W.

So I would need a knew PSU as well? (Grits teeth...) And how hard would that hit the bank?

Peripheral wise, I only have a USB wireless adapter and a small web cam, plus obvious mouse and keyboard.

BTW: Can I change my PSU without changing my case?

A new PSU may not be as expensive as you think some own make PSUs have a very good price tag (eg ... Here) it always pays to hunt around, and yes you should be able to change your PSU without changing your case, what case do you have ?

It says the case comes with a 400W PSU, but I the guy who put my computer together may have bought it without the PSU.

Hi Sycthus, you will have no probs swapping the PSU on that case

This seems to be a better buy, +50W for a pound less! But will that make it unreliable?

Bpth this one and the PSU you posted have only 1 PCIe plug. Can you get adapters to turn it into two?

Yes go for the 800w and you will get an adaptor with the Graphics card (PSUs with two 6pin plugs are designed for SLI and Crossfire)
